Metropolis Design and Prototyping is a full service product development and prototyping firm. Since 1989 we have been helping our clients grow their business by transforming ideas into successful products. Keeping design, prototyping, and small-run manufacturing under one roof guarantees better quality control and faster turn around times.

prototyping questions

Q: What do I need to get a prototype built
A: A 3d file is required to make an accurate quote and to build your part. An STL is preferred but we also can convert IGES, STEP, or SLDPRT. if you do not have a 3d file of your part our experienced design team can model it for you. We ask for wall thicknesses to be larger than .04 inches. Make sure your 3d part is a completely closed surface/solid model.

Q: What resolution are your rapid prototyping machines capable of?
A: The PolyJet process uses inkjet style technology to apply photo curing resin in layers only 16 microns thick (.0006 inches) or 1600 dpi. Each layer has an x and y resolution of 600 x 600 dpi. This results in rapid prototypes and rapid manufactured parts with highest resolution available and smooth surface finishes.
Our SLA machine typically has a layer thickness of .004 inches you can expect dimensions under 5” to be within .005 inches over 5”, expect +/- .002 inches.

Q: What are your lead times?
Our lead times for RTV tooling is typically 1 week.
Our lead time for rapid prototyping is typically overnight (depending on the size).

Q: What rapid prototyping machines do you use? A: We have two SLA (stereolithography) machines and a 3d Polyjet printer. For more information about our 3d printers click here.
