A look on 3D Printing’s future
Figure 1: Illustration of a 3D printing methodology.
The increased use of 3D printing is a trend that has a range of applications relevant to the manufacturing
supply chain. As an example, it can help in the sample management process as it is often quicker and less
costly to produce a sample. Speed and efficiency are two key advantages of 3D printing which are crucial in
the race to bring products to market if a new fad arises. 3D printing is also being used to advance custom
product ordering as it makes it easier to create customer-driven, tailored products to more closely fit the
requirements of the end user. 3D printing is categorised under Rapid prototyping processes, this is one of
the important steps to finalize a product design. It helps in conceptualization of a design. Before the start of
full production a prototype is usually fabricated and tested.
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital
file. The creation of a 3D printed object is achieved using additive processes. In an additive process an
object is created by laying down successive layers of material until the entire object is created. A virtual
design of the object is created. CAD (Computer Aided Design) uses a 3D modelling program or 3D scanner
for virtual design. The software slices the final model into hundreds or thousands of horizontal layers. The
printer creates the object layer by layer, resulting in one three dimensional object. Here, few important
Additive manufacturing processes namely Stereolithography (SL), Selective Laser Sintering (SLS), Fused
Deposition Modeling (FDM) and Laminated Object Manufacturing (LOM) are briefed:
Stereolithography (SLA) : Photopolymerization is used to produce a solid part from a liquid. This
technology employs a vat of liquid ultraviolet curable photopolymer resin and an ultraviolet laser to
build the object’s layers one at a time. UV Laser solidifying the pattern.

Fused deposition modelling (FDS) : uses a plastic filament or metal wire as input material to an
extrusion nozzle. The nozzle is heated to melt the material and can be moved in both horizontal and
vertical directions by CAM. The material hardens immediately after extrusion from the nozzle.

Laminated Object Manufacturing (LOM): process that creates models from inexpensive, solid- sheet
materials. It is similar to stereolithography in that it slices a three-dimensional electronic file from
the computer to the LOM machine to produce parts for visualization models, casting patterns, and
designs.

Selective laser sintering (SLS) : uses a high power laser to fuse input materials like plastic, metal,
glass, etc. It scans the powdered material layer by layer.

3D printing was once used in the generation of 3D puzzles and minimal applications in manufacturing.
However, the world of 3D printing, which may be referred to as additive manufacturing, is evolving. Through
the 3D scanning of items, manufacturers can streamline the design and manufacturing process to rapidly
create microscopically identical parts from nearly any location. 3D printing has major applications for the
creation of service parts much closer to the end user than historically available. In 2016, the use of 3D
printing for manufacturing will grow to focus on the customer-driven designing and co-creating of individual
items. This aspect of manufacturing in 2016 will dramatically change how customers view custom product.

alterations. Now, imagine these applications on a broader scale in all forms of manufacturing, such as
printing electronics on-site, during the construction of an airplane. This trend will really change the industry.
3D Printing technology could revolutionize and re-shape the world. Advances in 3D printing technology can
significantly change and improve the way we manufacture products and produce goods worldwide. If the
last industrial revolution brought us mass production and the advent of economies of scale - the digital 3D
printing revolution could bring mass manufacturing back a full circle - to an era of mass personalization, and
a return to individual craftsmanship.
