Introduction to 3D Printing
3D Printers
3D printers are used in designing and prototyping,
and production process. The objects that are
created in these printers can be of any shapes, sizes
or geometry. Today's 3D printers had their start in
the rapid prototyping (RP) technologies of the
1980s and found their use in the industrial market.
As patents expire, 3D printing technology is
becoming more available to consumers.
The 3D Printing Process
3D printers build objects using a process known
as additive manufacturing. Material is put down
in layers; each layer adds to the previous layer
and in turn becomes a base for the next layer.
Most 3D printers in the consumer market use
thermoplastic inks in the printing process. These
polymers become soft and pliable within a
temperature range and then resolidify when
allowed to cool.
How do 3D printers work?
These printers first formulate the fundamental design of
the object that you desire to form. This plan is made
through a CAD file which applies 3D modeling program
which is used to make a new project or it can also use 3D
scanner which duplicates the exact model of the object
and also builds a 3D digital file of the object. These
scanners put together different techniques for making 3D
models. For making a digital file for printing, the
software used in 3D modeling splits the final model into
millions of layers.
Technology used in the 3D printers
Different types of 3D printers make use of different
technologies. There are many ways that are available for
printing that merely differs in the manner by which the
layers are built to complete an absolute entity. While
some of the technologies use the process of melting to
produce the layers for which they utilise the process of
either selective layering or fused deposition. One of the
most widely used technologies is Stereo lithography. It
also makes use of other technologies like Vat photo
polymerisation, material jetting, sheet lamination,
powder bed fusion and many more.
3D Modeling
The printable 3D models can be shaped using CAD
package or 3D scanner that uses plain digital camera
and photogrammetric software. 3D scanning
procedure evaluates and saves digital data and makes
it materialize as a shape of a real object. Based on this
technique, three dimensional models can be
produced. Irrespective of the 3D modeling software
used, this 3D model gets converted into .STL or .OBJ
format to allow the software that prints the object to
make it readable.
Applications of 3D printers
3D printing finds many applications in various sectors
of industries from automotive to aerospace and aviation
to bioprinting and healthcare instruments. 3D printing
can also be of great use in creating objects of day to day
use, and personal projects.
The technology of additive system can deduct your time
from being wasted and help to print the object in few
hours.
3D Printing Services
3D printers are expensive and not everyone can afford
it for their individual purposes, and so there are various
companies and firms that offer 3D printing services.
There are also online 3D printing services which
deliver 3D printing services at economical price range
and can print and deliver any object from a digital file
that you upload to their website.
Finally, It's Fun!
For engineers, makers, and creators, it's a fun time to
get into 3D printing. Many sites offer files for
download, and there are options to utilize 3D printers
even if purchasing one isn't in your near future. As 3D
printers become more commonplace, more and more
uses will become available.
