PADT, a provider of simulation, product development, and additive manufacturing (AM) services and products, has been awarded a U.S. patent for its Support Cleaning Apparatus (SCA) system, invented by Rey Chu, Solomon Pena and Mark C. Johnson. The SCA systems are intended for use with any Stratasys 3D printers that use the Soluble Support Technology (SST) material, and are currently sold by Stratasys.

“When Stratasys first introduced its soluble support material that can be dissolved with chemicals to help remove supports in the 3D Printing process, we knew that existing support removal devices were not reliable or efficient enough to handle the innovation,” says Rey Chu, co-founder and principal, PADT. “We used computational fluid dynamics simulation, our extensive product development skills and knowledge from over two decades of 3D printing experience to design the industry’s most efficient and reliable support cleaning solution. We are proud that our SCA system has now been granted patent protection.”

PADT shipped its first SCA system in November 2008. There are currently two units in the SCA family, the SCA-1200HT with a 10 × 10 × 12" part basket and the larger SCA 3600 with a 16 × 16 × 14" part basket. The systems offer temperature ranges suitable to remove support from all fused deposition modeling (FDM) and PolyJet materials including: ABS, ASA, PC, nylon and PolyJet resins.
