• Digital fabrication technology, also referred to as 3D printing or
additive manufacturing, creates physical objects from a geometrical
representation by successive addition of materials. 3D printing
technology is a fast-emerging technology. Nowadays, 3D Printing is
widely used in the world. 3D printing technology increasingly used for
the mass customization, production of any types of open source
designs in the field of agriculture, in healthcare, automotive industry,
locomotive industry and aviation industries. 3D printing technology
can print an object layer by layer deposition of material directly from
a computer aided design (CAD) model.

5. Digital Fabrication Technology or
3D Printing, also known as Additive
Manufacturing, is a Revolutionary
Technology that enables the creation of
three-dimensional or physical objects from
geometrical representation by adding
material layer by layer. This process
opposite to traditional subtractive
manufacturing methods, where material is
cut away from a solid block to create the
desired shape.
INTRODUCTION

6.  First patent for Rapid Prototyping Technology ( Dr. Hideo Kodama)- 1981
{ use uv light to harden polymers and create object}
 StereoLithoGraphy (SLA) invented by (Charles Hull) – 1984
but release in 1987{ uses light-reactive thermoset material called “resin”
to create object}
 Selective Laser Sintering (SLS) Patent ( Carl Deckard) -1989
{ To create an object use laser to fuse polymer powder}
 Fused Deposition Modeling (FDM) Patent ( Scott Crump ) -1992
also known as Desktop 3D Printer{ To form object ,printer heats cable of
thermoplastic into liquid form and extrudes it layer by layer }
 Selective Laser Melting (SLM) (Dr. Dieter Schwarze) -2000
{ use high power laser to melt and fuse metal powder into solid object}
 Commercial available RepRap(Replicating Rapid Prototyper) patent (Dr
Adrian Bowyer) -2009

7. Constructing a 3D printer involves assemblingvarious
components to create a machine capable of printing
three-dimensionalobjects layer by layer.
Components Needed:
 Frame
 Print Bed
 Extruder
 Nozzle
 Motors and Belts
 Control Board
 Power Supply
 Controller Board
 Cooling Fan
 Hot End
 Filament/Raw Material
 Rods, Bearings, and Pulleys
CONSTRUCTION

9. 2D PRINTER VS 3D
PRINTER
2D PRINTER 3D PRINTER
Prints on a flat surface , like paper or
cardstock.
Prints 3D objects layer by layer.
Can only create 2D images or text Can create physical objects with depth and
volume
Uses ink or toner transfer the design onto the
surface
Use various materials , such as plastic ,metal or
resin ,to build the object
Commonly used for printing documnts , photos
and illustrations.
Commonly used for prototyping,manufacturing
and creating customized objects.

12. The future of 3D printing is bright and became an important pillar in
various manufacturing industries
 E.g.( Medical , Aerospace, Automotive, Defense, Architecture etc.)
 3D printing innovators are even exploring, how to make the process
itself more sustainable.
 Researchers are focusing on ,how to print of different material
integration.
 Future applications for 3D printing might include creating open-
source scientific equipment to create open-source labs.
Reconstructing heavily damaged evidence acquired from crime scene
investigations.
Reconstructing bones and body parts in forensic pathology.
 To construct complex engine parts
To construct on demand parts in space
