2. Introduction
3D printing is a form of additive manufacturing technology where a
three dimensional object is created by laying down successive
layers of material. It isalso known as rapid prototyping, is a
mechanized method where by 3D objects arequickly made on a
reasonably sized machine connected to a computer
containingblueprints 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.

3. 3D printing is the perfect
manufacturing method to
use if you need to do some
rapid prototyping. ... By
using 3D printing you save
time on your assembly

4. 3D Printers are machines that produce physical 3D models
from digital data byprinting layer by layer. It can make
physical models of objects either designed witha CAD
program or scanned with a 3D Scanner. It is used in a variety
of industriesincluding jewelry, footwear, industrial design,
architecture, engineering andconstruction, automotive,
aerospace, dental and medical industries, education
andconsumer products.

5. PRINCIPLES
• The manual modeling process of preparing geometric
data for 3D computer graphics is similar to plastic arts
such as sculpting. 3D scanning is a process of analysing
and collecting digital data on the shape and appearance
of a real object. Based on this data, three-dimensional
models of the scanned object can then be produced.

6. 3D PRINTING
• 3D printing consists of an inkjet printing system
• Layers of a fine powder are selective bonded by
printing an adhesive from the inkjet print head in the
shape of each cross section as determined by a CAD file

7. 3D PRINTING
• It is also recognized as the fastest method
• These photopolymer phase machines use an ultraviolet
flood lamp mounted in the print head to cure each
layer as it is deposited

8. Definition:-
3D + Printing = 3D Printing
3D Printing is a
p h r a s e u s e d t o
d e s c r i b e t h e
process of creating
three objects from
digital file using a
materials printer,
in a manner similar
to printing images
on paper.

9. Printing process
Printing is a process for
reproducing text and
images, typically with ink
on paper using a print
press.

11. History of 3d Printing
• 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.

12. The Basic Process of 3D
Printing
• 1.Create a CAD model of the design
• 2.Convert the CAD model to STL format
• 3.Slice the STL file into thin cross-sectional layers
• 4.Construct the model one layer atop another
• 5.Clean and finish the model

13. FINISHES
3D-printing is usually considered as a great technology for
ready-to-use object, but for many projects, an additional
treatment of the surface or the part is needed to reach
the desired rendering. To learn more about available
finishes at Sculpteo and when to use them or to get good
tips from our team for the different steps post-3D-
printing, you can refer to the following documents.

Stereo lithography (SLA)
Multi jet Modeling (MJM)
Laminated object manufacturing (LOM)
Electron Beam Melting (EBM)

17. SLS method
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).

19. Stereo
lithography is
an additive
manufacturing
process using a
vat of liquid
UV-curable
photopolymer ”
resin” and a UV
laser to build
parts a layer at
a time.

20. FDM
Fused deposition
modeling (FDM) is an
additive manufacturing
technology commonly
used for modeling,
prototyping, and
production
applications.

21. Laminated object
manufacturing
Laminated object
manufacturing
(LOM) is a rapid
prototyping system
developed by
Helices 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.

25. 3D printing Vs conventional
technologies
3DP does not and will not replace completely
conventional technologies such NC and high-speed milling,
or even hand-made parts. Rather, one should regard 3DP as
one more option in the toolkit for manufacturing parts.
Figure depicts a rough comparison between 3DP and milling
regarding the costs and time of manufacturing one part as a
function of part complexity10. It is assumed, evidently, that
the part can be manufactured by either technology such that
the material and tolerance requirements are met.

27. Types of Material Used
There are Many different materials can be used for 3D
printing, such as ABS plastic, PLA, polyamide (nylon),
glass filled polyamide, stereolithography materials (epoxy
resins), silver, titanium, steel, wax, photopolymers and
polycarbonate

33. 3D Printing Capabilities

34. 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
certain fields.
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.

35. 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
