3d printing
created by>Rakesh kumar.m>Trinity college of engg&tech.> 2nd- Ece.
A process for making a physical object
from a three-dimensional digital model,
typically by laying down many successive
thin layers of a material.
This also called as additive manufacturing.
INTRODUCTION
HISTORY OF 3D PRINTING
History of 3d Printing 3D PRINTER-DESIGNER
This technology
developed by Charles
Hull in 1984. He
named the technique
as Stereo lithography
and obtained a patent
for the technique in
1986.

performs creation,
modification, analysis, or
optimization of a design.

Current 3D Printing Technologies
Stereo lithography
Fig:2
In this process layers are added by curing photopolymers with ultraviolet light lasers. Hull defined the process as a "system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed.
Fused deposition modeling
fig:3
FDM begins with a
software process
which processes an
STL file (
stereolithography
file format).
Selective laser sintering
fig:4
Selective Laser Sintering (SLS) is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3Dmodel, binding the material together to create a solid structure
Multi-jet modeling

Ink jet printing comes from the printer and plotter industry where the technique involves shooting tiny droplets of ink on paper to produce graphic images.
VARIOUS 3D- PRINTERS
Vedio of 3d technology
In Medical Field, Surgeons are using 3d
printing machines to print body parts.
3D printing allows artists to create objects
that would be incredibly difficult,costly, or
time intensive using traditional processes.
Advantages
Product formation is currently the main use
of 3D printing technology.
3D Saves Time and Cost: Creating complete models in a single
process using 3D printing has great benefits.
This innovative technology has been proven to save companies time, manpower and money.
Misusage of this technology by anti-social persons like terrorists causes great effect.
Unchecked production of dangerous items. imitations of size, raw material. Cost of printers
DISADVANTAGES
We can give life to our ideas from our desktop.
Not time consuming process. 3D printing can provide great savings on
assembly costs. 3D printing could even challenge mass
production method in the future.
