Our 3DXSTAT™ ESD-Safe OBC is made using Evolv3D™ OBC (Olefin Block Copolymer) from Dow.  This is an engineering-grade material based on a novel polyethylene copolymer and multi-wall carbon nanotubes.  OBC is the state-of-the-art in polyethylene 3D printing and eliminates many of the problems associated with printing polypropylene-based materials. Target surface resistance:  10^7 to 10^9 Ohm.
