3D Printers

RSPro 1400

The Big Dimension in Stereolithography

This innovative dual laser-dual scanning additive manufacturing system is perfectly suited for the industrial production of large, high quality finished parts as well as mass part production.

System Features

  • Automatic calibration set-up ensures accuracy.
  • High precision parts with no visible joint lines.
  • Carbon fiber reinforced recoater system ensures non-deformation across 1400 mm length.
  • Granite recoater frame enhances stability.
  • Open design for freedom of choice of materials and software.
