3D Dental Printer - 05 Jun 2014

NEW from Stratasys - Stratasys have extended their 3D Dentistry printer range by introducing two new machines offering low cost wax-ups for Crowns, Bridges or Denture Frameworks.

Utilising WDM technology (Wax Deposition Modelling), a jetting technology that is designed to enable both consistent quality & a reliable process. The machines produce superior-fitting wax-ups for crown, bridge, coping and denture frameworks via an automated method that can fit easily into a lab's established workflow, enhancing production capacity.

Stratasys CrownWorx and FrameWorx 3D Printers use Truecast wax-like materials that produce smooth surface finishes to minimize your post-processing. The materials burn-out with no residue, material shrinkage, cracking or expansion to allow precision casting and reduce the cost incurred when finishing gold and other precious metals.

TrueCast and TrueSupport

TrueCast is a firm but flexible material that mimics real wax and allows labs to 3D print any dental wax-up with extreme accuracy. It is 100 percent castable for any alloy. TrueSupport is a true wax-blend material that is automatically generated to protect a wax-up during printing. It has a low melting point that produces delicate restorations and is easily removed from each wax-up, after production

Stratasys CrownWorx

Based on resolution, the CrownWorx 3D Printer is best-in-class for creating crown, bridge, and coping wax-ups. CrownWorx allows you to seamlessly transition to a digitized workflow so you can quickly and easily create quality wax-ups for crowns, bridges and other dental restorations. 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.

Stratasys FrameWorx

The FrameWorx 3D Printer uses WDM Technology to jet micro-drops of TrueCast material onto the build tray to create a denture wax-up layer-by-layer. TrueSupport material is quickly sprayed around the casting material to form a support structure. This enhancement increases production speed for partial denture wax-ups because they require more support material than crowns and bridges. After printing, TrueSupport is dissolved, leaving behind smooth and detailed wax-ups.
