Nanoscale 3D printing

March 14, 2012 By 17 Comments

This 3D-printed model of the Tower Bridge is only 200 micrometers long. To put that into perspective, the distance between the towers is the width of a human hair. This model is the product of research at the additive manufacturing department of the Vienna University of Technology

The models were fabricated much like normal stereolithography – a laser shines onto … Read the rest

Build your own Stereolithographic 3D printer

November 14, 2011 By 26 Comments

[Andy's] 3D printer build uses lasers to create objects from goo. The Stereolithographic process uses resin that is cured by UV light to create the finished product. A single laser mounted to a CNC gantry is able to precisely target a point on the surface of the resin to begin the printing process. As the layers are built up, … Read the rest
