Prototek Sheetmetal Fabricatin began in 1987, specializing in quick-turn prototypes for the precision sheet metal fabrication markets. Due to our success in our field, we have experienced two expansions and currently operate out of our new 40,000 sq.ft. facility in Contocook, N.H. In addition to state-of-the-art bending and welding departments, we offer laser cutting as well as a traditional turret department. We can also meet your milling and lathing.... read more
Stereolithography uses additive fabrication method where a UV-sensitive photopolymer resin is cured by a laser to build parts a layer at a time. Part are traced by the laser beam on the surface of the photopolymer, causing it to cure and solidify the prototype layer. After each layer has been traced, the build platform lowers the part by a single layer thickness, typically 0.002" to 0006", and sweeps a blade filled with photopolymer ("resin") across... read more
Z Corp uses an ink-jet based process that prints the 3D part's cross sectional geometry on layers of powder spread on top of each other. Powder is frist spread over the surface of the 'bild position'. Using the inkjet print head, the Z Corp printer sprays a binding solution onto the powder in the shape of the first cross section of the CAD model. The build piston lowers one layer and more powder is spread using the spreading apparatus... read more
