What is 3D-Printing
A printer that uses an additive process of successive layers of materials to create a 3D object.

Software Used to Give in
struction to
3D printer
are :-
Auto CAD
3dsMax
Blender
SketchUp
etc...
There are
6

main
methods for 3D printing.
Stereo lithography
Digital Light Processing
Selective Laser Sintering
Electron Beam Melting
Multi-Jet Modelling
Fused Deposition Modeling
Process of solidifying "liquid ultraviolet curable photopolymer", with a laser.

Traces out successive layer with a laser on to the resin.
Similar to stereo lithography but, uses a precision light -138 microns (the same precision of a laser).
Uses a high power laser to fuse small particles of plastic, metal (direct metal laser sintering), ceramic, or glass powders into 3D-Products.
Uses high temperatures to melt plastic. Then applies it layer by layer to create 3D object.

Plastic solidifies immediately on impact.
Applies powdered metal
In a vacuum, metal is melted using electron beam
Melted metal molds on to previous layer
Final 3D product is formed after many successive layers
Applies layer of powdered resin
Spreads a glue-like substance to solidify the resin as well as add color

3D Printing
- The first machine named SLA-250 was
delivered to the public

- Introduced Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS)

- FDM was invented by Scott Crump who
made the company Stratasys.
Timeline
- Massachusetts Institute of Technology (MIT) created a model

- similar to the Inkjet technology used in 2D printers

- called “3 Dimensional Printing techniques” (3DP).
- Z Corporation starting developing 3D Printers based on 3DP technology after acquiring the license from MIT
- The term “3D Printer” came to be due to 3 models of this time :

> "Genisys" from Stratasys,
> "Actua 2100" from 3D Systems
> "Z402" from Z Corporation,
- Spectrum Z510 was launched
- was the first high definition 3D Printer
- also printed in color
- Reprap (open source printing project) was developed in England
-The model made could replicate 50% of itself
- Connex 500™ by Objet Geometries Ltd.
was released
- Could make 3D parts using several different materials at the same time
Evolution of Methods
1. Stereolithography (SL)
2. Fused Deposition Modeling (FDM)
3. Selective Laser Sintering (SLS)
4. Dimensional Printing (3DP)
5. Polyjet

1984
- developed by
Charles Hull

- termed "Stereolithography Apparatus."

- founded "3D Systems"
which developed the first commercial
3D printer.
Future Scope / Conclusion
Endless Possibilities
Ability to create anything and everything
Many people will adapt to 3D Printer made appliance because of the customizations
Some industries might be gone in the future,
and some industries may rise.
- Vienna University of Technology made the smallest 3D printer
- Weighs 1.5 kilograms
- It costs only around 1200 Euros

Why should any one
use 3D Printer?
Increase Innovation
:- Print prototypes in hours, obtain feedback, refine designs and repeat the cycle until designs are perfect

Improve Communication
:- Hold a full colour, realistic 3D model in your hands to impart more information than a computer image. Create physical 3D models quickly, easily and affordably for a wide variety of applications.

Speed Time to Market
:- Compress design cycles by 3D printing multiple prototypes on demand, right in your office.



AutoCAD
:-
AutoCAD is a commercial software application for 2D and 3D computer-aided design (CAD) and drafting AutoCAD was first released in December 1982, running on microcomputers with internal graphics controllers.
Autodesk 3ds Max, formerly 3D Studio Max, is a professional 3D computer graphics program for making 3D animations, models, games and images.
Autodesk 3ds Max:-

Blender:
- Blender is a professional free and open-source 3D computer graphicssoftware product used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games.

Sketch up:-
Sketch Up (formerly: Google Sketch up) is a 3D modeling program for applications such as architectural, interior design, civil and mechanical engineering, film, and video game design.
• Step 1: CAD
-- The software may provide some hint as to the structural integrity you can expect in the finished product, too, using scientific data about certain materials to create virtual simulations of how the object will behave under certain conditions.


• Step 2: Conversion to STL
-- Convert the CAD drawing to the STL format. STL, which is an acronym forstandard tessellation language, is a file format developed for 3D Systems in 1987 for use by itsstereo lithography apparatus (SLA) machines.


• Step 3: Transfer to AM Machine and STL File Manipulation
-- A user copies the STL file to the computer that controls the 3-D printer.





Working of 3D Printer
• Step 4: Machine Setup
-- This includes refilling the polymers, binders and other consumables the printer will use. .

• Step 5: Build
-- Let the machine do its thing; the build process is mostly automatic. Each layer is usually about 0.1 mm thick, though it can be much thinner or thicker. Depending on the object's size, the machine and the materials used, this process could take hours or even days to complete

• Step 6: Removal
-- Remove the printed object from the machine.

• Step 7: Postprocessing
-- Many 3-D printers will require some amount of post-processing for the printed object. This could include brushing off any remaining powder or bathing the printed object to remove water-soluble supports.

Reduce Development Costs :-
Cut traditional prototyping and tooling costs. Identify design errors earlier and reduce travel to production facilities.

Win Business :-
Bring realistic 3D models to prospective accounts, sponsors and focus groups.

Personalise products :-
Personalise merchandise such as pens and other items at conventions etc. This can increase mindshare with potential clients.
Another way 3D printing is more cost effective is because it is a lot faster than most traditional methods of manufacturing. Where traditional methods can take up to days to make a particular object,

3D printing only takes up to a few hours.
This saves a lot of valuable time, which in turn saves money. Along with being faster and more cost effective,
another benefit of 3D printing is that it produces less waste. Since 3D printing uses additive process, it only makes what is required. Because traditional
manufacturing uses the subtractive process, at times most of the original material is removed and not useful anymore. With less waste, companies will save on material costs, and that will have a significantly lower impact on the environment.
