Abstract
Additive manufacturing technology (AMT) popularly recognized as 3D printing is a disruptive technology that has the potential to change many conventional or subtractive manufacturing methods such as drilling, forging and machining. The technology is capable of joining some materials and creating objects from 3D computer-aided-design (CAD) model data, usually layer-upon-layer in distinction to traditional subtractive manufacturing technologies. Among others, there are popular techniques, such as stereolithography (SLA), fused deposition modelling (FDM), powder bed fusion and inkjet 3D printing (3DP), which are employed broadly in low quantity components production for more than a few applications. Additive manufacturing gives many strategic advantages, inclusive of extended design freedom for constructing complex internal and external section geometries that cannot be made in any other way, and the potential to repair expensive components for aerospace, clinical and many different industries. In this work, an overview of additive manufacturing processes and their impact on industrial practice is provided. Discussions are on some of the medical, automobile and aerospace applications of AMT and the usage of the SWOT analysis, describing the strengths, weaknesses, opportunities and threats dealing with AMT applications. Manufacturers, therefore, can adopt this technology for standardization of quality manufacturing practices in our country.

Nice write up,
Thank you Sir Paul
This is a well articulated paper, with good graphics to make studying interesting.
Good one Mr. Woju
Thank you Sir UgoWise
From the point here….. I can say that this guy is highly intelligent to help in moving the way forward in Engineering Sector….. Kudos Bro
Thanks Engr Attah.
AMT… The way forward in our manufacturing industry. You have written well!
thanks Ms Amara
Nice
This is great. Woju is an explicit writer. More knowledge. Nice work. Please Woju what is the operational principle of this technology
Thanks for your comment Sir Henry.
Now concerning the question: the operational principle of this technology. As noted in my work, this technology otherwise known as 3D printing is a manufacturing technique that builds objects layer by layer directly from raw materials in powder, liquid, sheet or filament form using a 3D CAD model data without the need for moulds, tools or dies.
I hope this satisfies your question Sir.
Alright Woju. I understand it very well now.
Great job well done. Kudos
Keep the good works sir
It’s a good topic to discuss on which can help elavate the manufacturing industry.
The word “Additive Manufacturing Technology” as used in your paper is indeed a huge one but you expressed it by saying popularly known as 3D printing. I do disagree with you on this one because that is not all to Additive Manufacturing Technology because we have so many like Powder Metallurgy, Metallurgy itself etc. I think you need to recast your abstract such that it can capture what you intend to say. Thanks
Thanks for your comment Sir Ebikemefa.
Concerning your uncertainty, 3D printing is the versatile generic name or word used to describe the additive manufacturing technology. Others like powder metallurgy is stereotype to just the use of metal powders. Hope I have cleared your uncertainty Sir.
Permit me to say this: Hope you understand the meaning of the word ”generic name”. How does generic name imply to additive manufacturing technology. This is more of technical explanation and not a biological term. Also, 3D printing has to do with a technology that included the layer to layer addition of materials such that it can be seen in a 3 dimension form which agrees to additive manufacturing but it is not a generic name as you claim.
Furthermore, i think you need to recast that line. Thanks
Maybe you need to understand that the word “generic” implies that a word that is applicable to an entire class or group.
From my knowledge of”generic” it means something general so you be the one getting the author wrong.Still,I maybe wrong.
Thanks for your comment Sir Ebikemefa.
Concerning your uncertainty, 3D printing or additive manufacturing technology is sometimes used interchangeably. Additive manufacturing (AM) or 3D printing is the broader and more all-inclusive term. Others like powder metallurgy is stereotype to just the use of metal powders. As you read along my full paper, you will understand the different various technologies of AMT. Hope I have cleared your uncertainty Sir.
Mr author, you have not done justice to making good clarity on what i pointed out and also, as a point of notice, my stated observations are not ”uncertainty” as you often use. They are observations which are drawn from your work. I will let this slide but i am still not clarified on the both issues i raised. To some extent i may say i do understand where you might be driving to but your usage of word is misleading. That i must say
My usage of word is not misleading at all. Only that you fail to recognize that language is dynamic and so is its use.
Generic is not only used in biology. It is technical in every sense as meant in the field of engineering just like saying specimen can only be used in biology which is not true. It is an engineering term too.
Exactly,generic are not only used in biology,it can be applied in any field as in generalization usage.
It’s cool
Thank you Ebuka
Also, most of your key words are not in align with the topic. Examples are Opportunity, Challenges …. All these can be discussed probably under your scope or methods but it has nothing to do with your key words. Thanks
That’s not correct. In fact they constitute an important aspect of discussion in the paper.
this is an educative write up keep the flag up
Thank you Charles Michael
Wonderful..just like every bit of it keep it up and see ur self excel with God knowledge

Nice work
Thank you Engr. Favour Ndubuaku
Great read.
Do you mind adding in your next article, how developing countries like Nigeria can take steady efforts to additive manufacturing?
Thanks for that additional insight Sir Christian
AMT is the next big thing in the manufacturing world. It’s so nice gleaning some beautiful insights from piece. Kudos Moses.
Thanks coach. Your help and proofreading went a long way bringing me this far. I’m grateful
This is such a wonderful piece!
Thanks
Wow, nice piece of work here.. A really great engineer in the making. Expecting more articles from u
A very educative essay
Alright
I will always take advantage of related opportunities. Thanks to NESTEC for this one and thanks to you also for commenting.
Great and well articulated essay. Inspiring one indeed.
Nice write up. Its clear that AMT will impact positively to the manufacturing industry and as such a great technique to adopt.
Kudos Moses for this great insight!
Yes indeed!
AMT will greatly reduce the amount of materials used in the production of engineering components and as such increase the efficiency of production.
You did well, further reviews greatly recommended sir, so as to improve upon your position.
Keep up the nice work
Alright Sir Abednego
Whereas traditional methods requires the gradual removal of materials from a large material until the desired shape is gotten and this removed materials becomes waste thereafter, the AMT methods involves the addition of materials to the digitally defined AM system slice upon slice or layer upon layer and saves the amount of materials used with more reliable dimensional accuracy.
From here we can deduce that AMT is the future of manufacturing industries and should be adopted even here in Nigeria.
Thank you
@Wojuola, Oladamola Moses, I believe you will be an astute researcher and writer. Keep evolving in this your might
God willing Uncle Ben.
I am really aware of my potential of an astute researcher. I am evolving and thanks to NESTEC for giving me a chance on this platform
Nice abstract but am still going through your paper.be expecting a question later in the day
ok Sir Favour
This is good.
Thanks Sir
Quite insightful. Keep it up Moses.
Thank you Engr. Samuel
I love this write up. It’s inspired me..
You are a good writer bro and no doubt about your outstanding skills and techniques….
Great engineers.
#wealth of the #Nation
Thanks Brother. Greater opportunities ahead
This piece is incredibly superfluous
Nice one Bro Damola
Thank you Ziks Dara for your comments. You encourage me
Hi friend, such a nice papar you have here. However, thier are some over sight i would love to highlight. Taking about AMT being limited for mass prodcution, it actually depends on the type of AMT process considered, for instance proceses like selective laser sintering that uses a very high energy laser to sinter photo sensitive resins is a very rapid process that can be utilized for mass production. Also, i exoected you talk about some of the ethical issues suroonding the use of AMT as some countries are consdering putting strict policies on this technology. Thanks
Thanks Sir Ukeje for your comments,
Going through your statements, I can’t find any oversight I proposed you were trying to oversight. For example, let us consider an automobile production. Theoretically speaking, AMT can be used to produce the whole components of a vehicle but due to the large components that needs to be produced, it is quite expensive. But then as the saying goes in the world of engineering that what is valid today can become obsolete tomorrow, many processes are still unfolding to improve upon and combat the current challenges of additive manufacturing.
And next time sir, please try to put your words together as I had to go extra length to understand some of your statements by my instinct. Thank you for your time.
Good day author, i just came across a word in your work that caught my attention and i immediately had to check for the meaning. The word is ”disruptive”. It simply means causing disrupt or unrest. Permit me to say that such word has no technical basis to clarify your audience as regards what your abstract is conveying. Thanks
Once again Sir Ebikemefa, you have just misjudged the context of my paper. I didn’t just said disruptive but “disruptive technology”. Maybe you didn’t check the meaning well. A disruptive technology is one that displaces an established, old, conventional and traditional methods or technologies and shakes up the industry, the manufacturing industry in this context and creates a new industry altering the way manufacturing is been done with greater and reliable properties.
‘Engr’ Woju thumbs up for good work here. Well done.
Thanks Sir for going through my paper. Please do well to ask questions for clarity and knowledge sake. Thank you
What a deep research… I have learned a lot from this your piece. Well done sir.
Knowledge and the world of research altogether is progressive. That I must admit. Thanks Sir
Nice work Woju.
I’ll appreciate if you can clarify me on the irregularities AMT is said to avoid. For example the use of AMT to print in licensed weapons for terror attacks…. I believe you know my point.
Thank you Mr Oscar for your question. But it seems you mix up your questions here because there is no clarity in your statement. Nevertheless, I will give you the answer as to what I think you are trying to ask.
One of the irregularities that AMT is said to avoid is the lengthy time it takes to produce fixtures or molds creation to produce a component using conventional methods of production.
Concerning the use of AMT to produce weapons for terror attacks is one of the ethical constraints that will be addressed by governmental policy on the use of this technology. Any company that wants to use this technology must obtain a license from the governmental agencies or body that oversees the issues of production or manufacturing in Nigeria.
well sir, i am still trying to relate this to what Nigeria needs now?
Its a very brilliant work but then how can every Nigerian benefit from this 3D printing and how does it boost the economy, image and of course the standards of a developing country like Nigeria
Here are the ways every Nigerian can benefit from the adoption of this technology ranging from students to the governments.
1. They enable authentic exploration of objects not readily available to schools – e.g. ancient structures and fossils
2. They help develop spatial intelligence – mentally generating, rotating, and transforming objects in
3 dimensions
3. They also have broad cross-curricular applications – e.g. examining arts and relics related to our history (physics/history/ICT) or designing and marketing different kinds of products (art/design/economics/ICT)
4. They address key points in national curricula – planning projects, employing technologies, executing design tasks, sharing, examining, and reviewing work, etc.
4. They stimulate students’ imagination, creativity, and independent-thinking – providing many opportunities for self-directed projects and truly original creation
5. They prepare students for the jobs of tomorrow – whether in engineering, design, science, medicine, manufacturing, or economic management setting up the foundation of a creative (not consumptive) life – a generation that does not only buy but rather principally makes and sells.
6. The development of SME’s can spur new economic growth is a strategic decision worth considering. It will yield savings on foreign exchange, on spending for expensive spare parts and give government the chance to spend on new programs.
7. When we visit the road-side garages or inner city metal works areas located in different parts of Nigeria, one is convinced that with a fabrication tool like 3D printers, the concentration of creative minds in Nigeria can be unleashed to formulate a new successful economy; an economy dominated by maker-communities digitally connected but located at different parts of our country.
8. Lastly, one can easily apply this technology in our houses; to 3D print a broken metal door handle instead of having to wait for a welder. Likewise, it can be used to fix little toilet fixtures instead of waiting for a plumber.
Nice write
Thanks Sir for going through my paper. Please do well to ask questions for clarity and knowledge sake. Thank you
This work will be of great improvement to our Engineering system. Could you please show us more benefits. Thanks
Thank you Sir Abiola for your comments.
Here are the following benefits AMT can offer:
1. They make abstract concepts tangible – e.g. visualizing 3-dimensional geometric objects and modeling chemical molecules
2. They enable authentic exploration of objects not readily available to schools – e.g. ancient structures and fossils
3. They help develop spatial intelligence – mentally generating, rotating, and transforming objects in
3 dimensions
4. They also have broad cross-curricular applications – e.g. examining arts and relics related to our history (physics/history/ICT) or designing and marketing different kinds of products (art/design/economics/ICT)
5. They address key points in national curricula – planning projects, employing technologies, executing design tasks, sharing, examining, and reviewing work, etc.
6. They deeply engage ALL students – even those whose attention tends to drift. Every one’s stimuli is up when it comes to learning a new technology.
7. They stimulate students’ imagination, creativity, and independent-thinking – providing many opportunities for self-directed projects and truly original creation
8. They prepare students for the jobs of tomorrow – whether in engineering, design, science, medicine, manufacturing, or economic management
9. Lastly, they set the foundation of a creative (not consumptive) life – a generation that does not only buy but rather principally makes and sells.
I hope this is enough benefits we can derive from the adoption of this technology, AMT. Thank you.
No sir, i do strongly disagree with you if you say 3D and Additive Manufacturing is used interchangeably because you must know the fact that every word has its different meaning in all fields. I am not disputing the fact that 3D printing can also be seen as Additive Manufacturing but my ”bone of contention” is when you said Additive Manufacturing is… ”popularly recognized as 3D printing”. This is highly professionally fallacious because other field might see it differently from what you intend to represent. I think you may have reconstructed it in a much better way such that all field or discipline can relate to your work with full understanding of what you are conveying. 3D printing can also be said to be Additive Manufacturing but don’t say it is popularly recognized as Additive Manufacturing Technology. Wikipedia put it this way …”which is why it is also called additive manufacturing…” This is much more better because it brought it to a point where all field can relate to it from the authors point but not what you said in your abstract. If you say that it is popularly called, it means all filed and discipline sees Additive Manufacturing as just 3D Printing which is really not true. Thanks
hmm Sir Ebiks, there seems to be something that you don’t understand about the use of language. One thing you should know is that language is dynamic, a ruler does not only mean a stick used for measurement. It can also mean a person in authority. As such what I meant that additive manufacturing is popularly recognized as 3D printing is that it gives its product as a 3-dimensional shape output and hence the popularly known as a 3D printing.
Good morning brother. It was a pleasure reading though your paper. I have got some questions I’d like to put through for your answers.
1. It was obviously a fact that additive manufacturing AM helps in easy manufacture of high-tech weaponry. Do you think a country like Nigeria with terrorism threat (Boko Haram indeed) should employ something that would help people in acquiring weapons easily—you know how the country is good at intelligence, ironically?
2. AM is also known to consume high power in its process. Do you think it is realistic with the present paralytic power supply of the country for the AM to be implemented?
Thank you Sir Abdulbaki for your question.
One thing we should understand is that technology is not bad in itself but technology in the hands of a criminal is worse, not only bad.
Thanks for your comments Sir Abdulbaki.
What an interesting question.
Considering the fact that AMT can be used to produce high-tech weapons, it is therefore paramount for our national security step up their game by proactively setting up additional regulations and measures in the direction on the use of this technology that will thwart worst case scenarios.
Good day Mr. Abdulbaki.
Concerning your question on the issue of the current epileptic power supply we are experiencing in Nigeria and the. A common concern for manufacturers in Nigeria is the unreliable power supply, but research has shown that, that won’t be a problem. Each 3D printer consumes about 100 watts, about as much as a few light bulbs, and little enough that two printers could be powered by one solar panel.
Mr. Wojuola, it indeed a good work you have here. But, I have some questions and needs further clarifications:
Can you explain this statement, ” Recent tendencies in AMT have reduced the value of 3D printers.” As used in your paper, I don’t really understand the statement.
Secondly, in section 3.1 where you explained sintering, you said: sintering is similar to traditional 2D photocopying where toner is selectively melted to form an image on paper (figure1d)..”
My question is, what is the relationship between that statement and figure 1d (powder bed fusion).
Can you explain how “Hype and unrealistic expectations” serves as a threat to AMT. And you didn’t defined Manufacturing 4.0 as additive manufacturing, or does it connote something else?
What is the full meaning of .STL and ‘GE’ as used in your work?
The challenges outlined in your work, is it specific to Nigeria alone or a general factor affecting the globe.
More so, do you agree with that statistics that in the subsequent 5 years to come AMT will be used for producing 75% of engineering components?
Also, I don’t understand why AMT as a whole is not fit for mass production
Lastly, what makes you work different from other publications of this sort?
Thank you once more for the knowledge shared. I would be glad if the answers to my questions are provided in Clare conscience.
Thanks for your comments.
The recent tendencies I meant is that considering the large availability and improvements of AMT so far, it is now easier to acquire a 3d printer for commercial use without industrial restrictions as information on how to operate one is readily found on the Internet.
Furthermore, the Powder Bed Fusion (PBF) technology is used in a variety of AM processes, including direct metal laser sintering
(DMLS), selective laser sintering (SLS), selective heat sintering (SHS), electron beam melting (EBM) and direct
metal laser melting (DMLM) (Figure 1d).
The relationships between these systems or how they relate is that they use lasers, electron beams or thermal print heads to melt
or partially melt ultra-fine layers of material in a three-dimensional space. As the process concludes, the excess
powder is blasted away from the object.
What I mean by that statement hype and unrealistic expectations is that even though this novel technology is promising, it cannot still replace the whole manufacturing methods such as mining or extractive metallurgy or where a conventional method is more viable for mass production of a component.
Manufacturing 4.0 simply means the fourth industrial revolution.
.stl simply means STereoLithography or standard triangle language or standard tessellation language.
GE means General Electric
It is a name of a company that specializes in the use of this technology to produce high-tech aviation jet nozzles.
, since my paper is focused on Nigeria, the challenges as posed is specific to only Nigeria.
Good day Mr Ebuka.
From my research so far, AMT is already been used in the biomaterials engineering field to print prosthetics, hearing aids, kidneys and replicas of a beating human heart. Also, while the US is working on making a3D printed car, China has already printed a house using AMT. Now, we can come to an agreement that 3D is continuously growing and it is the future of our consumer lifestyles.
AMT is not fit for mass production yet because of its huge capital investment.
What makes my work different from others of this sort is basically my unique approach to addressing this novel technology and how it can boost our manufacturing practices.
I respect this wonderful work sir.
Keep it on
Thanks sir Great
The point made by this erudite scholar is very clear on the above topic. It’s really a nice and interesting topic and he did justice to it.
Thanks Sir for going through my paper. Please do well to ask questions for clarity and knowledge sake. Thank you.
Nice write. AMT is an impressive improvement in the manufacturing industry. Thanks to the author for the enlightenment
Thanks Sir for going through my paper. Please do well to ask questions for clarity and knowledge sake. Thank you.
Wonderful write up.
Thank you sir Sam
The paper has introduced a new more of doing things in the field of engineering. It is worth further exploring.
The paper has introduced a new way of doing things in the field of engineering. It is worth further exploring. But, how effective do you think this method can be and have you tested it anywhere?
Thank you Sir Gideon for going through my paper.
Concerning your question above, this technology is effective in that while there is a lot of material wastage in mass manufacturing, there is hardly any wastage in 3D printing. This translates to low costs of production and cheaper products that is affordable.
I hope this satisfies your question Sir.
Thank you
I have not tested it anywhere Sir but I am making plans to get a training soon at YTF academy. Thank you.
Nice write up. But I need you to expantiate on the following; (1). What method of metal joining is adopted in the various additive manufacturing processes you highlighted in your abstract? (2). What’s the cost implication of this process & how does it impact on the final cost of the product?
Thank you Sir Ojo for your comments.
Concerning your questions
1. The methods used in additive manufacturing include the Powder Bed Fusion: This technology uses a variety of additive manufacturing processes like Direct Metal Laser Sintering (DMLS), Selective Laser Sintering (SLS), Direct Metal Laser Melting (DMLM) etc. These technologies use lasers, electron beams or thermal print heads to melt or partially melt ultra fine layers of metal materials in a 3-dimension space, and as this process concludes, excessive powders are blasted away from the object.
There are still other methods used in additive manufacturing and they are well articulated in the full paper. Kindly find the blue link below the abstract to download and please ask me more questions after going through it and I will gladly reply. Thank you.
2. Unlike mass manufacturing, or subtractive manufacturing, where pieces are cut from raw materials and assembled into the final product, 3D printing makes objects by adding materials layer by layer. While there is a lot of material wastage in mass manufacturing, there is hardly any wastage in 3D printing. This translates to low costs of production and cheaper products that are affordable. Thank you
Great stuff here. Would really like to see how this can be applied in more industries and how developing countries like Nigeria are able to tap into this. Well done Mr. Wojuola.
Good job hope to see more from you. Keep it up.
Nice write up sir.
Quite informative
Also, note that the additive manufacturing process, is not a holistic manufacturing process. In that, you need some form of subtractive process to complement the additive process. Most components can not function in isolation. You need to assemble components together to get a desired product. Therefore, after producing a component additively, you need to subtractively drill holes for fasteners so it can be assembled with other components. Take your refrigerator compressor for instance. In summary, the additive process though very good, but can not entirely “disrupt” the conventional subtractive process. You need to combine various manufacturing processes in varying degrees to achieve your result
Thank you Sir Ojo for your insightful comments.
Wow, this is superb. A new method in engineering that needs to be implemented. How can it become effectively maximized?
Thank you Mmerichi Agina.
This technology can be effectively maximized by introducing it to our schools and colleges of higher education and also our government should encourage the industrialization of this technology by promoting small scale enterprises in line of this technology. These ways I believe it can be effectively maximized.
Great piece!
Thank you Presh

Thank you Chukwukaire for your comments.
In my own views, I will say its high time we start developing interest in the intricacies of a technology than the results we derive from them. AM is one of those technologies. I mean we can build our own AM technology, learn how it works and use it to develop our local contents.
Great one Wojuola!
Thank you Nkechi
Nice write up
I actually learnt that AMT is of great important to engineering sector in all around including production,designing and Construction etc
And it help to minimize material for production.
Thank you Chikasie for your comments. AMT is the future of contemporary manufacturing industries. Yes they help to reduce the materials cost by minimizing the amount of materials needed to produce a component without compromising the mechanical properties of the final product and eliminates wastage of materials as is the case of other conventional manufacturing methods.

You have alot to offer mr.moses…Go hard! Man…impossible is nonsence
Thank you Abonyi Kingsley.
Awesome article, hope we see an implementation of this technology in our industries as soon as possible. Knowing this country, I’m not holding my breath.
Like seriously we need to step up in our manufacturing industries and stop limiting ourselves to a consumptive lifestyle. This technology is a good step in a right direction as it makes manufactured parts easier and faster to produce. We will not need to go through lengthy process of molds creation or pattern making before we can produce spare parts to replace damage parts of a product or to make life easier through the adoption and proper implementation of this additive manufacturing technology (ies).
Thank you Prince Chuks for your views on this paper.

It’s really awesome. More grease to your elbows. What a superb technology that changes the way we do manufacturing most especially in this part of the continent. Nice work. Keep it up Sir.
Thank you Engr Okafor Frankline for your comments. Really this technology changes the way we get things manufactured in this part of the continent. It does not require lengthy processes of manuals molds or pattern creation. It simply uses the 3d CAD software model data that converts the designed product to a language that the AM system understands i.e. standard tessellation language (.stl) format. It is the information that now guides the nozzle path or print head to precisely deposits the material we are using as our layering material (metal powder, thermoplastic, ceramic or even edibles like chocolate) upon the preceding layer until our solid model is completely designed from the bottom layer up to the upper layer. Then cools or cures and we finally gets our 3d product.
Having perused and digested this article,I vehemently recommend the implementation of this technology.
Thank you Engr Frank for your comments.
Really it is countries that adopts and invests in technologies that benefits from it.
Nice one. .
Keep it up!
Thank you Engr Steve

It’s a very useful process for production, especially for intricate designs.. But in a country like Nigeria, do you also recommend it’s application considering that fact that it will drive many workers into extinction?
Thank you Odo Vital is for your comments.
Yes I strongly recommend the adoption of this technology in Nigeria. As a matter of facts this technology cannot drive workers into extinction, instead it will put manufacturing in the hand of individuals. This way we can build of network of makers-community and boost our economy.
A wonderful research work. Keep it up
Thank you Chike Nweze

Thank you Michael Hannah for the comments.
Very good work
Thank you Okoye Peace for your time going through my paper.
This is superb. Indeed a new method in engineering that needs to be implemented. How can it become effectively or implemented.
At least there should be a way to start this.. Or what do u think Bro.
This write up shouldn’t just be a read and comment or like, but something positive must emerge..
At least an experiment or operation should be done with this..
Thank you brother for your comments.
This technology is currently being adopted in many professional career fields that include engineering and biology as a result of the technological advancement in developed countries. Only countries that adopts this technology will reap the economic benefits.
Nice write-up, Oladamola. However, what prospects are there of achieving economic growth through additive manufacturing?
In addition, what is required for sustainable impact on the manufacturing industry in Nigeria?
Thank you Sir Victor Akpan for your views and comments.
However, in response to your questions, the prospects Additive manufacturing technology offers to our economic growth are in the following areas:
1. When applied in our educational sector i.e. trainings offered in our colleges of education and universities. They prepare students/youths for the jobs of tomorrow – whether in engineering, design, science, medicine, or manufacturing, setting up the foundation of a creative and not consumptive lifestyle – a generation that does not only buy but rather principally makes and sells – a generation that is not just interested in the end result of a technology but also in the making of that technology.
2. Likewise in the manufacturing sector – When we visit the roadside garages or inner city metal works areas located in different parts of Nigeria, one is convinced that with a fabrication tool like 3D printers, the concentration of creative minds in Nigeria can be unleashed to formulate a new successful economy; an economy dominated by maker-communities digitally connected but located at different parts of our country. This is one aspect that really excites me about this AM technology. We can create such an enabling environment where we can email 3d CAD files or products from one location to another where we have a 3d printer and then print out the 3d physical object in space.
Also from research, AM has
been identified as having the potential to provide a number of
sustainability advantages. These advantages include the generation
of less to no waste during manufacturing due to it being an additive
process; the capability to optimize geometries and create lightweight components that reduce material consumption in
manufacturing and energy consumption in use, just as the saying “the lighter, the more efficient”; the subsequent
reduction in transportation in the supply chain; and inventory
waste reduction due to the ability to create spare parts on-demand.
In addition, investment in infrastructure and innovation/technology are required for sustainable impact on Nigeria’s manufacturing industry as they serve as crucial drivers of economic growth and development in as much as they improve our competitive performances and advantages.
I do hope this satisfies your questions Sir.
Hi Moses, great tech paper. What, in your view, is the primary benefit of additive manufacturing to SMEs in Nigeria?
Thank you Engr. Ben for your views and question.
From the wealth of my research and my point of view, the primary benefit of AM technology to SMEs in Nigeria is easy fabrication of small quantity of customised components faster than traditional manufacturing techniques, which drastically reduces the “time to market”, cost, and ability to create spare parts on-demand.
Nice one
Much love Daniel🙌
Its a Good Research
Thank you Omaliko Ugochukwu
Its quite awesome and I am cool with it

Additive Manufacturing Technology (AMT) is the new way to go in manufacturing, and it will be a very good innovation in Nigeria’s manufacturing system! It’s a really superb technique!
What intrigues me is it’s geometrical preciseness
I can recall that i wrote a paper about Additive Manufacturing four months ago (June, 2019)
I
Wow. You did😱
Well that’s good to know.
Another interesting feature of AMT is it’s digital nature. The fact that I can email a 3d CAD file or product to another location where there is a 3d printer and just print out the 3d physical object without any sweat.
Thank you Engr. Ogunkayode Oluwaseyi for your comments.
Nice write up 👍
