We are responsible for the phenomenally popular Chicago Model City on public display at the Chicago Architecture Foundation.  The entire model all 25 feet, by 35 feet, is 3D printed - so, yes, we know about this technology. We bought our first 3D printer in 2002. 

All our machines read a three-dimensional computer file generated by us or generated by our client and processed by us. Each has its own input requirements and parameters, creates builds using different processes, and is best for producing different types of models. 

The Objet Eden  prints a .001” layer of liquid urethane that is then hardened with UV light. The largest part that can be built by the Eden is 9 ¾” x 9 ¾” x 7 ¾” high. Small texture like detailing can be approximately 0.015’’ or less. Small wafer like objects can be as thin as .045”. Most should be .0625” (1/16”). Taller, vertical wall-like objects require additional thickness and/or supports. 

The
 Dimension machine lays down a melted bead of ABS plastic that is about .010” in diameter, one layer at a time. The largest part that can be built by the Dimension is 7 ¾” x 7 ¾” x 11 ¾” high. Small details should be at least .0625" (1/16") thick. Lager objects must be at least 0.125’’ (1/8’’).  

The Form 2 prints a 0.001” (0.025mm) thick layer and uses lasers to solidify acrylic resin, each layer fused onto the layer before it. (Stereo lithography)  Form 2 parts can be clear or white or painted the color of your choice. This is the highest level of surface finish of all our machines. A lattice of support material is generated by the machine from the same acrylic material, so generally the parts are easy to clean and finish than other 3D printing technologies.
