What is 3-D Printing?
3-D Printing is defined as the
process of building 3-D objects by the use of CAD model (Computer-Aided
Design). 3-D printing is also called Additive Manufacturing, it is a collection
of processes which are used for the creation of 3-D objects depending on the
computer control. 3-D has appeared with this name in 1990s but, in that time,
it was being used for rapid prototyping only. Nowadays, 3-D printing techniques
are used widely in the industrial field for creating complex objects.
The production of very complex
geometries became very easy with the discovery of 3-D printing. Electronics was
manufactured by 3-D printing processes for the first time in 2014 when the
first multi material (VIPRE) was demonstrated by Dr. Manos M. Tentzeris and Dr.
Benjamin S. Cook.
General Principles of 3-D Printing
Modeling_ CAD packages are used for
creating 3-D printing models. These models are known by the possibility of
correcting errors before printing. In this step, a digital model is created for
the object by collecting the data about the shape and appearance of the
required object, it’s called 3-D scanning process. The information about the
object is stored on the STL file which is a CAD file format.
Printing_ It’s required to examine
the file for checking if there are errors before printing. These errors are
fixed if found then, a slicer is used to process the STL file for converting it
to series of thin layers. After that, it can be manufactured by any type of 3-D
printers.
Finishing_ it’s the last step of 3-D
printing. In this step, the needed accuracy can be achieved by different
processes. The object can be also curved or improved by using different
additive manufacturing techniques.
How will 3-D printing change our future?
3-D printing became one of the most
important techniques in the world. People started to use 3-D printing in all
fields without exception. Scientists expect that 3-D printing will change the
world in the near future. This expectation can be true according to the
following points:
§ All kinds of
business will be affected by 3-D printing for being able to fit market needs.
So, business models have to be changed by applying new strategies. 3-D printers
can easily exist at homes so, companies have to do their best to get new
customers.
§ 3-D printing
will lead to a huge improvement in the medical field. Human body parts can be
now manufactured accurately to fit all bodies which will help to increase
people’s quality of life.
§ By 3-D printing,
you will be able to get any product with the specifications you need. The
companies which offer the customization possibility of products will be the
best in the near future.
§ When using 3-D
printing in factories in the future, the production process will be better and
more efficient and the products will be cheaper.
§ In the future,
the world will start to manufacture anything by using 3-D printing techniques;
cars, machines, and even planes.
