3D computer graphics are graphics which are
using three dimensional representation of
geometric data (by Wikipedia)
Printing process
Printing is a process for
reproducing text and
images, typically with
ink on paper using a
print press.
3D + Printing = 3D Printing
3D Printing is a
phrase used to
describe the
process of creating
three objects from
digital file using a
materials printer, in
a manner similar to
printing images on
paper.
Different methods
Selective laser sintering (SLS)
Stereolithography
Fused deposition modeling (FDM)
Laminated object manufacturing
SLS method (not SLS Mercedes)
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
SLS method
STEREOLITHOGRAPHY
Stereolithography
is an additive
manufacturing
process using a
vat of liquid UV-
curable
photopolymer ”resi
n” and a UV laser
to build parts a
layer at a time.
FDM
Fused deposition
modeling (FDM) is an
additive manufacturing
technology commonly
used for modeling,
prototyping, and
production applications
Laminated object manufacturing
Laminated object
manufacturing (LOM)
is a rapid prototyping
system developed by
Helisys Inc. In it, layers
of adhesive-coated
paper, plastic or metal
laminates are
successively glued
together and cut to
shape with a knife or
laser cutter.

What is ABSplus?
ABSplus is a production-grade thermoplastic that
gives models the ability to perform just like
production parts in real-world functional testing.
How it works ? Stratasys FDM (Fused Deposition Modeling) technology
provides the foundation for all Dimension 3D printers. Two
materials — one for models, one for support — are
heated in an extrusion head and deposited in thin layers
on a modeling base. The model is precisely built layer
upon layer. When the model is complete, the support
material is removed leaving an accurate, durable
functional 3D model.
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

SUCCESS stories
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;
