Soft Elastomers for FDM

From: Jan Helge Bohn (

We have developed the capability to fabricate with soft thermoplastic
elastomers on FDM 1600 rapid prototyping systems. The resulting parts
are soft (72 Shore A), tough, smooth and without the "pinholes" found
in ABS parts fabricated by FDM. Support structure removal is quicker,
cleaner and easier than that of other FDM build materials (i.e., P400,
P301, and ICW05).

This technology can be made ready for commericialization within months
for FDM 1600, 1650, 2000 and 8000 rapid prototyping systems.
We are seeking beta-sites and investors.

NOTE: This material was developed with assistance of Stratasys, Inc.
===== It is our intention to continue to develop this and future FDM
       materials in collaboration with Stratasys, Inc. and to market
       resulting products through Stratasys, Inc. only.
