3D at the speed of 2D

The z.trusion® technology upgrades one of the most commonly used manufacturing technologies in the world, namely extrusion*. By retrofitting the z.trusion® technology onto existing extrusion lines, 3D structures and topologies can be achieved in one easy manufacturing step.

*Extrusion typically involves forcing material through a die to create a continuous profile, but it is limited to a fixed cross-sectional shape.

The invention

The patented z.trusion® technology uses integrated rotating elements in the pressurized zone of the extruder to manufacture complex structures with remarkable precision and minimal resource consumption and is 100% compatible with any existing extrusion lines.

"Designers really go crazy when they realize the potential we bring"

Mikael Eklund, CEO at Reliefed – the home of z.trusion®



All materials that are normally suitable for extrusion can be used, until proven otherwise. Even some materials that are normally not intended for extrusion are possible to use with z.trusion®.

  • Polymer
  • Rubber
  • Aluminum
  • Ceramics
  • Composites
  • Bio-composites
  • Cork composites
Profile width/height
Width: 5—500 mm
Height: 1—100 mm
  • Cut-outs are possible along the edge of the profile in the extruded direction
  • Punch-outs for holes and other features are possible, depending on the surrounding geometry
  • Holes through a profile are possible in certain materials
