This document discusses 3D printing and additive manufacturing. It describes subtractive manufacturing and casting/forming as traditional manufacturing methods that remove or shape materials, whereas additive manufacturing builds objects up layer by layer from materials like plastic, metal or ceramic powders. Specific additive methods covered include selective laser sintering, stereo lithography, fused deposition modeling, and laminated object manufacturing. The document outlines the benefits of 3D printing such as reduced waste, complex designs, and customization, but also notes potential intellectual property and misuse concerns.

1. A Technology towards revolution
3D PRINTING

2. Printing is a process for
reproducing text and images,
typically with ink on paper using a
print machine.

3. Subtractive Manufacturing
Additive Manufacturing
Casting
Forming

4. Creates a product by removing
sections from a block of material.
Generates waste through the
excess material that is removed.
Limited design capabilities.
EX: CNC machines
lathe
milling machines etc.

5. Creates a product through adding
materials to the object.
Adds material layer by layer until
printing is finished.
Allows for complex and intricate
designs.
EX: 3D printing

6. A method of Additive Manufacturing that
adds material to an object layer by layer
to create the final product.

7. Selective laser sintering (SLS)
Stereo lithography
Fused deposition modeling (FDM)
Laminated object manufacturing

8.  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

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

10. • CAD (Computer
Assisted Design)
Programs help users
create STL Files for the
3D Printers to read.
• STL
(STereoLithography) file
format – a file format
which uses many little
triangles to make a 3
dimensional plot of the
objects intended

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

12. Laminated object
manufacturing (LOM)
is a rapid prototyping
in this process layers
of adhesive-coated
paper, plastic or metal
laminates are
successively glued
together and cut to
shape with a knife or
laser cutter.

13. Technique

14. • Prototyping
• Modeling
• Custom parts
• Design
• Research

15. • 3D printing with non harmful chemicals.
• 3D printing generates almost no waste during
manufacturing, and does not require lubricants.
• 3D Printing can be used to create replacement parts.
• High flexibility in design.

16. Intellectual property rights of the 3D Printer users.
Nearly anything can be printed by 3D Printers and this
is a troubling prospect if criminals use 3D Printers to
create illegal products.

17.  Nothing communicates ideas faster than
a three-dimensional part or model. With a
3D printer you can bring CAD files and
design ideas to life – right from your
desktop.
