As 3D printing becomes more commonplace in the dental industry, Stratasys introduces two new high-precision wax 3D printers—CrownWorx and FrameWorx. Both devices use wax deposition modeling technology to produce well-fitting wax-ups for crown, bridge, coping, and denture frameworks through an automated method that could enhance production capacity. The CrownWorx and FrameWorx 3D printers both use wax-like material that produces smooth surface finishes and reduce post-processing. The materials leave no residue, material shrinkage, cracking, or expansion.
CrownWorx is for manufacturing crown, bridge, and coping wax-ups. WDM Technology is used to jet micro-drops of TrueCast—a flexible material that mimics real wax and allows for accuracy—in order to build dental wax-ups, layer-by-layer. FrameWorx also uses WDM technology to jet micro-drops of TrueCast material, but does so for denture wax-ups layer-by-layer. TrueSupport—a wax-blend material that is auto-generated to protect a wax-up during printing—is sprayed around the casting material to create a support structure. TrueSupport is dissolved after printing.
