3D print the industry’s most accurate wax-ups

WDM (wax deposition modeling) produces extremely precise wax-ups with incredibly fine detail and smooth surfaces, in a casting material that burns away clean for a beautiful final product with minimal post-processing. The technology is consistent, reliable and repeatable so you can create high-quality dental restorations every time, every day.

How WDM Technology Works

WDM 3D Printers build smooth, detailed casting wax-ups by jetting tiny droplets of a wax-like material called TrueWax onto a build tray. Where overhanging shapes and complex geometries require support during production, the 3D printer deposits a removable wax-blend material called TrueSupport.

  1. Imaging: A dental scanner or CAD program generates a high-resolution 3D image to be exported as an STL file and prepared for 3D printing.
  2. Pre-processing: Specialized software automatically calculates where and how much TrueWax and TrueSupport material to deposit.
  3. Production: The 3D printer heats and deposits the materials onto a build plate, one fine layer at a time. After each layer is deposited, a fine rotary planer levels the build surface to ensure accuracy before adding the next layer.
  4. Post-processing: The support material easily melts away at a relatively low temperature to reveal a wax-up ready for immediate investment casting.

WDM 3D Printing Benefits

  • Create wax-ups for crowns, bridges and partial dentures, directly from digital files.
  • Achieve high-quality casting with minimal post-processing.
  • Produce the industry’s most accurate wax-ups with a resolution of 5,000 dpi on the X and Y axes and 8,000 dpi on the Z axis.
  • Avoid shrinking, expansion, cracking and residue with WDM materials that burn away cleanly. Formulated specifically for investment casting in dental applications, WDM materials are safe and TSCA-registered, and require no special waste disposal.
