3D Printing

What is 3D printing ??

In 2007 3D printing was suggested for artistic purposes. we people are used to get printed copy of any digital file, but what if we could get a three dimensional object as a result of printing a digital file !!

How it works ??

3D printing or we can also call it additive manufacturing is a process for making three dimensional object from a digital copy. In an additive process an object is created by creating suitable layers of material. All the layers can b seen and differentiated uniquely as a thinly sliced horizontal cross-section of eventual object.

Technologies and methods of 3D printing :

Selective laser sentering (SLS)
Fused deposition modeling (FDM)
Stereolitheography (SLA)

What is SLS ?

Selective laser sentering is a process of building three dimensional parts using laser sentering which means heating and fusing a powdered material. It was developed by Dr. Carl Deckard in middle of 80's.

What is FDM ?

Fused deposition modeling commonly used technology for modeling, prototyping and production applications. It was developed by Scott Crump in late 80's.

What is SLA ?

Stereolitheography is a technique for creating three dimensional object in which computer controlled moving laser is used to build the required structure.

Applications :

• Design visualization
• Metal casting
• Architecture
