Introduction 3D printer is a modern technology in which 3

dimensional objects are printed from digital data Three dimensional object is created by laying down

successive layers of materials.

History

The technology for printing physical 3D object from digital data was first developed by Chuck Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1984.

What is 3D Printing? 3D Printing is a form of additive manufacturing in which

components are fabricated in an additive fashion by adding successive layers of materials together.

It is also know as: Rapid Prototyping Additive manufacturing.

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created.

How 3D Printer Work????

How 3D Printing work1. A person created a of an item using a computer aided

design Software Program.

2. The CAD information is send the printer.

3. The Printer forms the item by depositing the materials in layers, Starting from the bottom layers on to a platform. In some cases light or lasers used to harden the materials.

How 3D Printing work

General Principles Modeling

Printing

Finishing

Modeling Additive Manufacturing tasks virtual blueprints form computer aided design

(CAD) or animation modeling software and “Slices” them into digital cross-sections for the machine to successive use a guideline for printing.

Printing The perform a print, The machine read the design and lays down

successive layers of liquid, powder, or sheet materials to build the model from a series of cross sections. These layers, Which cross ponds to the virtual cross section from the CAD model, are join together or automatically fused to create the final shape. The primary advantage of this technique is its ability to create almost any shape or geometrical feature.

Finishing Though the printed product resolution is sufficient for may

applications, Printing a slightly oversized version of the descried of in slandered resolution, and the removing materials with a higher-resolution subtractive process can archive a higher-resolution.

Different Methods

Stereo lithography

Selective laser sintering (SLS)

Fused deposition modeling (FDM)

Ink-Jet 3D Printing

Value proposition of 3D Printing

Fabrication on demand

Shorter Product development time due to rapid prototyping

Less reliance on logistics

Mass Customization

Caters to each individual’s wants and needs instead of mass production and consumption

Advantages

Print movable parts Print Items in remote locations Ability to send items over internet and print out at home Plastic use is strong

Disadvantages

No regulations on what can be made example weapons Kids could print out dangerous Items Provide advantages for criminals Counterfeiting Expansive

Examples

Conclusion

Nothing communicates ideas faster than a three dimensional parts or model. With a 3D printer you can bring CAD file and design ideas to life- right form your desktop. Test form, Fit and function as and many design variations as you like with functional parts.
