How Does 3D Printing Work?
Let’s just say at some point in our lives as humans, we’d often wish
it was possible for some of the things running through our mind to
exist in the real world. Like. I remember wishing someone would just
buy me a PS 1 console back in the days. Well, in the world we live in
today, I’m glad to say we’re finally getting to the era where we could
get things just as they were in our imaginary minds. This is the era
of 3D printing and in this post, we are going to be looking at how 3D
Please understand that while we at fortune hill homes try to
describe how 3d printing works, we’ll also throw more light on how
this technology is going to better our lives now and in the future.
Let’s just describe 3D printing as one of the revolutionary
technologies of the 21st century. It’s a revolutionary technology
because it’s going to usher a new way of doing things, whether in
medicine, engineering, art, robotics, space travel, in all aspects of
3D Printing Techniques
Well, there are tons of 3D printing technology in the world today, but
we’re going to be looking at the 4 most common forms;
How Does 3D Printing Work?
It’s very important to understand that there are other forms of 3D
printing that might not be discussed in this article today this is
because we saw the need to create awareness on the most widely
used 3d printing Techniques today.
Let’s explain these techniques briefly
Fusion Deposition Modelling
FDM is an acronym for Fusion Deposition Modeling. The FDM 3D
printer is the one you must have seen in real life.
Let’s see how it works
How does an FDM 3D printer work?
This type of 3d printer works like a hot glue gun. But this time, a hot
glue gun operated by a robot.
In this printer, a solid material known as the filament enters the
printer in one end and is pushed off through a hot nozzle which
melts this filament and after then, lays it in layers.
The entering and melting, laying in layers is a sequence that
continues till a full Three-dimensional object is achieved.
What this means is that we could liken the Fusion Deposition
Modeling to a 2D printing. The slight difference is that after each
layer, the Hot Nozzle goes off what’s created and starts printing the
next layer right on top of that printed before lifting off.
This is also known as SLA. It works by casting ultraviolet light into a
pool of photoreactive resin.
The resin solidifies on receiving the ultraviolet light to form a layer of
the object being printed.
The difference between Fusion Deposition Modeling and Stereo
Lithography is that the SLA produces objects with finer details than
Now let’s talk about the other 3D modelling technique which is laser
laser Sintering working by casting a very powerful laser beam over
a layer of superfine powder thereby fusing the particles to produce a
thin solidified layer
On achieving the thin solidified layer, the machine further sweeps
more powder over the top of the layer and continues to repeat the
sequence a 3D object is completely created…
laser Sintering 3D Printers are not used in domestic
environments, however, they are industrially used to create large
and durable objects from metal.
Recent research mentioned that SpaceX uses laser Sintering
technique to manufacture super Draco rocket engines
PolyJet 3D Printing Technique
The PolyJet technique combines Fusion Deposition Modeling and
Stereo Lithography techniques to achieve its objectives.
In PolyJet Technique, the machine squeezes out tiny droplets of
photoreactive resin onto a built surface and this resin is hardened
with ultraviolet light. The process is repeated several times till the
object is formed from the bottom to the top
The PolyJet is a 3D printing technique that is super fast with
precision. However, you might be a bit disappointed to learn it costs
a couple of tens of thousands of dollars to buy 1.
Application areas of 3D printing
Because we care about quality and spreading the good news about
latest technology, we shall be talking not only How 3D Printers work,
we want to share with you the various areas where the innovation
would be more appreciated
As you know, in prosthetics, every limb, arm needs to be customized
for every individual which makes it a bit hard for prosthetics to be
produced on a larger scale. Thanks to 3D printing which has made it
so easy to the extent that a person’s body could be scanned and fed
into the printer which then produces a copy to match the body
geometry of the benefactor.
Well, in the world of medicine, 3D printing doesn’t only work for
prosthetics, it also touches such areas as organs. This is because
scientists did print a mini human heart from stem cells. the heart
printed with this technology is about 40% functional and currently
used for pharmaceutical studies.
Well, the heart so printed isn’t fully functional, but we believe a few
advancements would be made within a few years that would enable
the printing of more than a thousand functional hearts that could be
used for heart transplant surgeries.
3D Printed Shoes
Take it to the doors of NIKE. The company is currently running their
fly brand. The fly brand is a collection of 3D printed textile to be used
in the production of sneakers. These shoes are easily customized
for specific sports or athletes and the process allows these shoes
to be designed 16 times faster than regular shoes
3D Technology in Construction Industry
Well, as we speak, there is a home known as Appis Coe in Russia,
another in Dubai and Germany. These were 3D printed homes. We all
understand how rigorous the construction industry has been over
the years. It would take an advanced Construction company a few
weeks to build a home. But with 3D printing, a home could be built
within 24hrs and at a very reduced cost since labour and wastages
won’t be there.
Still on construction. A nonprofit startup company, ICON printed
homes that provides 800 square foot living spaces. These are
affordable housing solutions that cost less than 5000USD…
The technology has helped the construction industry provide
housing solutions in poor communities. These are cheap and quick
to build since the 3D printer is there to print the walls in layers.
Let’s remember it takes over 2 years to build a yacht. But with 3d
Printing, this Herculean task would only take 90 days.
The showbiz industry uses 3D Technology in Set design and prop
making. Allows studios to create custom props quicker and far very
cheaper than traditional it would be in traditional methods.
What about 3D printed meals? Nova is using 3D printing to print
foods such as Sushi, Pizza, Burgers, etc. It is believed that 3D
printed food could be the solution for the world’s food shortages in
the nearest future.
Truth is, with 3D printing, we could outgrow printing rocket engines,
prosthetics, objects and find ourselves in a world where even
humans could be printed with machines
Conclusion: How Does 3D Printing Work?
While we were able to understand the different types and
techniques in 3D Printing, we were also able to mention some
application areas that we believe the technology would bring
improvements to. Finally, we were able to understand that 3D
printing is a technology that has more benefits to offer. Now that i
understand how 3D Printers works, i am sure it would bring much joy!
Yes, i can’t wait to be able to print my favorite Marvel Superheroes
as soon as i lay my hands on a 3D Printer
