Stratasys Crownworx

The Stratasys Crownworx is great for:

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.
