1. What is 3D printing?

3D printing is also known as desktop fabrication or additive manufacturing, it is a prototyping process whereby an real object is created from a 3D design. The digital 3D-model is saved in STL format and then sent to a 3D printer. The 3D printer then print the design layer by layer and form a real object. Read more..

This video describe how laser-sintering process melt fine powders, bit by bit, into 3D shapes.

 

2. 3D printing technologies

Quite a few technologies are capable to do 3D printing. The main differences are how layers are built to create parts. 

SLS (selective laser sintering), FDM (fused depostion modeling) & SLA (stereolithograhpy) are the most widely used technologies for 3D printing. Selective laser sintering (SLS) and fused deposition modeling (FDM) use melting or softening material to produce the layers. 

This video describe how laser-sintering process melt fine powders, bit by bit, into 3D shapes.

The video belows explains the process of Stereolithography (SLA).

Generally, the main considerations are speed, cost of the printed prototype, cost of the 3D printer, choice and cost of materials and colour capabilities.

 

3. The history of 3D printing

October 5, 2011 – Roland DG Corporation introduced the new iModela iM-01.

Sep, 2011 – Vienna University of Technology, a smaller, lighter and cheaper printing device has now been developed.

This smallest 3D printer weighs 1.5 kilograms, it costs around 1200 Euros.

Aug, 2011 – The world’s first 3D printed aircraft created by Engineers at the University of Southampton.
