Shapeways has an elasto-plastic material, I believe it’s made by Materialise (TPU 92A-1). I need a prototype made from this material (or similar) but the lead time from Shapeways is a little to far out. Does anyone know of a North American based company that can print with this material?
Solid Concepts. Expect a price several times that of Shapeways but a lead time measured in days, not weeks.
Their PolyJet machines can print in an elastic material.
Try Airwolf. They make their own (I believe) TPU filament that is ShoreA87, designed to run on their machines, but it’s 3mm (2.88mm) filament:
