For the dental industry, the new Vida cDLM, from EnvisionTEC, is the second 3D printer based on EnvisionTEC’s patented Continuous Digital Light Manufacturing (cDLM) technology, which allows accurate, high-speed 3D printing with fewer supports. The Vida cDLM will have limited availability in the second quarter, with a full production launch to follow.
The original Vida 3D printer launched in 2015 has helped drive EnvisionTEC’s global machine sales up 29% in 2016 over 2015. Overall, sales of 3D printers to the dental industry grew 75% in 2016 over the prior year.
The Vida cDLM has a build envelope of 3.78 x 2.13 x 3.94 in., but puts print speeds into overdrive with continuous motion of the build platform in the Z axis. The machine is accurate, with an XY resolution of 50 microns and a Z resolution range of 25-150 microns, depending on material. The new technology also reduces the need for supports, allowing for easier cleanup and 3D printing of castable partial frameworks with delicate clasps.
EnvisionTEC will have a new 3D printing material, E-Model, an accurate and durable resin that has been in development for more than a year. It is suitable for creating models for thermoformed aligners, crown and bridge models and more. The material can also be printed on EnvisionTEC’s large production 3D printers such as the Vector 3SP, which does not require consumable parts.
E-Model joins EnvisionTEC’s dental materials library for 3D printing. That library includes three recent material releases that are now shipping to consumers:
E-Dent 400, which is more affordable than E-Dent 100, for the direct printing of temporary crowns, bridges and roundhouses.
E-Gum, which was previewed at LMT Lab Day in 2016, creates flexible gingiva masks for integration into 3D printed dental models.
E-Guard, also previewed at last year’s show, is an FDA-approved biocompatible crystal clear material for direct production of accurate night guards, bite splints and retainers.
