Stratasys Crownworx

CrownWorx allows you to seamlessly transition to a digitized workflow so you can quickly and easily create quality wax-ups for crowns, bridges & other dental restorations.

The Stratasys Crownworx is great for:

  • Creating dental crowns, bridges and partial dentures.

Based on accurate, reliable WDM (wax deposition modelling) technology, CrownWorx 3D prints in a familiar wax-like material that works with your normal investment-casting process.

You gain digital accuracy and efficiency by running CrownWorx unattended day, night and weekends. It essentially adds an automated second shift to your model-making capacity, freeing your hands and mind for other activities. The system incorporates an icon-based user interface for intuitive programming and operation; no special design knowledge is required to run it.

With software specially optimized for small, detailed wax-ups, CrownWorx delivers the highest resolution in the industry (5,000 x 5,000 x 8,000 dpi). This results in reliably precise margin lines and occlusal morphology. Wax-ups can then be directly investment cast, with minimal post-processing.

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.

  • 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.
  • Pre-processing: Specialized software automatically calculates where and how much TrueWax and TrueSupport material to deposit.
  • 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.
  • 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.

Enjoy Per-Unit Savings

CrownWorx can create exceptionally thin-walled wax-ups, saving material costs, labor and finishing time. Plus, its large build plate can easily produce 35 to 40 restorations a day, so you can reduce or eliminate hand-waxing and its associated costs.

    CrownWorx uses non-toxic WDM materials that burn away clean with no ash, residue, shrinking, cracking or expansion, and pose no biohazard or disposal concerns.

    TrueCast model material is firm but flexible, enabling you to 3D print any dental wax-up with extreme accuracy. It’s 100 percent castable for any alloy.

    TrueSupport enables 3D printing of even the most delicate restorations, and melts away easily before casting.
