3D printing is a form of additive manufacturing technology where a three
dimensional object is created by laying down successive layers of material. It is
also known as rapid prototyping, is a mechanized method whereby 3D objects are
quickly made on a reasonably sized machine connected to a computer containing
blueprints for the object. This revolutionary method for creating 3D models
with the use of inkjet technology saves time and cost by eliminating the need to
design; print and glue together separate model parts. The basic principles include
materials cartridges, flexibility of output, and translation of code into a visible pattern.
3D Printers are machines that produce physical 3D models from digital data by
printing layer by layer. It can make physical models of objects either designed with
a CAD program or scanned with a 3D Scanner. It is used in a variety of industries
including jewelry, footwear, industrial design, architecture, engineering and
construction, automotive, aerospace, dental and medical industries, education and

History of 3d
• The technology for printing physical 3D objects from digital
data was first developed by Charles Hull in 1984. He named
the technique as Stereo lithography and obtained a patent
for the technique in 1986.
• While Stereo lithography systems had become popular by
the end of 1980s, other similar technologies such as Fused
Deposition Modeling (FDM) and Selective Laser Sintering
(SLS) were introduced.
Selective laser sintering (SLS) is an additive manufacturing technique that
uses a high power laser (for example, a carbon dioxide laser) to fuse small
particles of plastic, metal (direct metal laser sintering),ceramic or glass
powders into a mass that has a desired 3-dimensional shape).

As anticipated, this modern technology has smoothed the path for numerous new
possibilities in various fields. The list below details the advantages of 3D printing in
1.Product formation is currently the main use of 3D printing technology. These machines
allow designers and engineers to test out ideas for dimensional products cheaply before
committing to expensive tooling and manufacturing processes.
2.In Medical Field, Surgeons are using 3d printing machines to print body parts for
reference before complex surgeries. Other machines are used to construct bone grafts
for patients who have suffered traumatic injuries. Looking further in the future,
research is underway as scientists are working on creating replacement organs.
3.Architects need to create mockups of their designs. 3D printing allows them to come
up with these mockups in a short period of time and with a higher degree of accuracy.
4.3D printing allows artists to create objects that would be incredibly difficult, costly,
or time intensive using traditional processes.
What will be in the future?
For many products the
standard conveyors can
be greatly reduced or
completely replace by
3D-printer, because the
end product - for
example, a car - will not
be collected from
hundreds or thousands of
individual parts but will be
produced in one process
Auto parts: for example, parts of "Formula 1" car engines, are made by
direct laser sintering of metal;
Aircraft parts: F-18 (fight aircraft) tube for the control system environment;
Individual orthodontics: the company Align Technology uses the 3D
Printing to generate accurate individual dental braces for hundreds of
thousands of patients worldwide by stereolithography from 3D-scans of the
mouth; polymer is used as a material for the production of staples;
Individual hearing devices: manufactured by companies Siemens
and Phonak, based on 3D-scan of the ear canal, so that the device is ideally
suited to the user;
Relatively New Technology.
