Process description

Material Jetting is an advanced extension of ink jet tech used by conventional 2D printers. A print head deposits a small amount of either liquid or particles which is fused to the rest of the print using different methods depending on the material type. This process is most often used with a UV curable resin, but processes also exist for metals and ceramics.

Strengths & Weaknesses

Strengths

  • Resolution: High precision print heads allow for very fine detail.
  • Multi-material printing: Multiple jets in the print head make it possible to print multiple materials together.

Weaknesses

  • Supports required: Supports are required for overhangs.
  • Post processing: Parts often require a second cure to fully harden.
  • Limited materials: Material Jetting printing is limited to waxes and photopolymers.
  • Slow print times: Since very little material is placed down at a time, production times can be very slow.

Machine Ranges

Material Jetting is capable of producing high resolution parts at large sizes.
