3-D Printer Produces Polymer-Based Dental Appliances

Dentistry Today


Kulzer’s cara Print 4.0 3-D printer can produce polymer-based dental appliances in-house. According to the company, it provides a cost-effective alternative to milling for certain indications and is more competitively priced than other 3-D printers on the market while meeting all accuracy requirements. Applications include night guards, impression trays, surgical drill guides, dental models, and CAD-to-cast structures, with most printed in less than an hour.

The cara Print 4.0 uses Digital Light Projection (DLP) for performance that’s quicker, more economical, and more accurate than laser-light technology, Kulzer reports. It’s also faster than most other DLP printing systems, the company says. Plus, it produces smoother and more homogenous surfaces than competing 3-D printers, according to Kulzer, while its long-lasting resin tray remains transparent and stable as long as it isn’t mechanically damaged.

The cara system for 3-D printing is open, working with open STL files commonly used by CAD programs such as 3Shape’s Dental Designer. The printer includes cara Print CAM software, with no hidden licensing fees. Kulzer encourages technicians to use cara Print 4.0 with the company’s dima Print materials, followed by post-curing in its HiLite Power for the highest quality results and guaranteed clinical performance.
