The process
of printing in 3D consists of creating the objects in layers superimposed from
bottom to top. Before starting printing, the software divides the 3D
graphic into layers as thin as the diameter of the output plastic. For
each layer, the printer moves on the plane to release the plastic on the
appropriate coordinates. Finally forming a three-dimensional
figure, an object that you can touch and use in real life. A 3D printer is
basically a three-axis numerical control (CNC) machine and an
extruder. The extruder is the component that heats and presses the plastic
cable (the ink) so that it comes out as a fine thread and remains with the
desired shape. How much does 1kg of plastic yield? The equivalent of
392 chess pieces, they calculated in Makerbot once!
Areas where 3D Printing is already
used
Architects:
The hours it
takes to make an architectural project model are the main savings for
professionals in this industry when
using 3D
printing as a work tool. The other important factor is the precision
obtained with the use of these machines and how possible it is to make a
physical part with dimensions that respect the designed or modeled digital
pattern. A third component, and no less, is the possibility of applying a
variety of interesting materials, such as plastics, rubber, wood, cement, among
others.
Jewelry:
3D printing
offers a shortcut to traditional lost wax casting processes. Fewer steps,
greater possibilities of creation and savings in materials, are some of the
advantages in its application in this business.
Medicine and Dentistry:
The
materialization of bio models to apply in the
practice and surgical planning of different branches of medicine is already
common with 3D printing. From exportable files of tools such as Scanners,
tomographs or ultrasound scanners, it is possible to materialize all or part of
the model obtained digitally. This allows the professional to work and
plan practices on personalized and real
models of a patient
Injection molds:
Injection
molding is still the preferred process for manufacturing high-volume plastic
parts, which is why it is used to create things like housings, containers,
bottle caps, combs, and other mass-market
applications.
Education:
The use of
these tools in the educational field forces an incalculable impact in the
future. In different areas of a standard curriculum, the possibility of
materializing ideas in a short time gives educators infinite
possibilities. Mathematical models, mechanical parts, tools, design
objects and parts of the human or animal anatomy are just some of the
possibilities open to students when using these technologies in the school
environment.
Rapid prototyping:
This is a
growing service with the appearance of this technology and its application
possibilities. The generation of on-demand prototypes has grown a lot in
recent years and continues to increase with the continuous emergence of new 3D
printing methods.
Industrial Designers:
This is
perhaps the most common user, due to its use independently or in your company
or industry. It is who should be the one who obtains the greatest
advantages from the use of technology by being responsible in the process of creating
products.
Small-scale Final Products:
Due to its
low cost and speed in obtaining products, for many market niches the supply of
products from the use of 3D printing is a viable way. Design products,
decoration, games, toys, accessories, are some of the examples of the use of
this technology to reach final products without the need to go through a
traditional manufacturing method or depend on dies or molds.
