DIPROmat develops low-shrinkage olefin compounds for large-format polymer printing

Materials developer DIPROmat reports new olefin-based compounds that shrink noticeably less than conventional semi-crystalline plastics. The company aims them at pellet-fed and robot-based large-format printing, where material behaviour largely decides dimensional accuracy. Founder Uwe Stenglin presented the work in the 3D Druck Podcast.

Context Semi-crystalline plastics shrink as they cool and crystallise, which warps large printed parts and makes dimensional accuracy harder to hold.
