6 Vídeos, 6 Métodos de Impressão 3D

Dúvidas sobre Impressão 3D?
Pois eis aqui, pela Ponoko, 6 diferentes métodos de Impressão 3D, explicados por Vídeo:


Vai aqui só o primeiro, vão ao Blog para os outros 5:

The different technologies behind 3D Printing

What we call “3D Printing” includes different fabrication methods. It would be more accurate to call it “Additive Manufacturing”. Only one technology works like printing and worth to be called 3D Printing: it’s 3DP.
- Stereo Lithography Apparatus (SLA) use a vat of liquid UV-curable photopolymer “resin” and a UV laser. Exposure to the UV laser light cures, solidifies the pattern traced on the resin. It was developed by Chuck W. Hull (co-founder of 3D Systems) in 1986

Graphene's 'quantum leap' takes electronics a step closer
by Staff Writers
Manchester UK (SPX) Jul 27, 2011

Writing in the journal Nature Physics, the academics, who discovered the world's thinnest material at The University of Manchester in 2004, have revealed more about its electronic properties.

Research institutes and universities around the world are already looking at ways to build devices such as touch-screens, ultrafast transistors and photodetectors.

Now the research from the creators of the material promises to accelerate that research, and potentially open up countless more electronic opportunities.

3d printed Mario Kart racers
Bored architect + Makerbot = totally awesome RC turtle shells

Michael Curry (aka Skimbal) has brought Mario Kart gaming nostalgia to life with his remarkably comprehensive Turtle Shell Racers.
I think we can all agree, life would become much more interesting if I launched a turtle shell at you every once and a while.
All of the .stl files are available on Thingiverse, including full assembly instructions and a parts list for the electronics, motor and other RC components needed to get those wheels turning.

E já viram o TAMANHO desta Impressão 3D, atenção, do nosso amigo Junior, vejam isto!!!

O nível de detalhe é poreiro...
Este exemplo acima, faz-me lembrar que com o método da Resina permite vários materiais, tal como cera, para Fundição de Molde de Cera Perdida, para Ourivesaria!
