Dental labs must produce several parts in multiple materials for either removable partial denture (RPD) applications or dental implant cases. For example, each implant case comprises a top and bottom rigid opaque model, a soft gingiva mask, and a biocompatible surgical guide. This requires three different materials, forcing technicians to either use multiple 3D printers or do separate 3D prints using different materials.
Stratasys Ltd. introduced a new 3D printer that gives dental labs 3D printing efficiency paired with PolyJet’s realism and precision. The J5 DentaJet 3D printer is the only multi-material dental 3D printer, enabling technicians to load mixed trays of dental parts. The new 3D printer can produce at least five times more dental parts on a single mixed tray, yet its compact footprint consumes only 43sqm of floor space.
The multicolour, multi-material J5 DentaJet also produces 3D-printed case presentations with realism previously only possible using time-consuming wax models. Now designs can be produced digitally in a few hours. The high resolution of PolyJet materials means dentists can seat crowns and bridges in minutes due to the accuracy of the models – to 18.75 microns, or less than half the width of a human hair.
‘Dental and orthodontic models have been growing their adoption of 3D printing but the process has remained too manual and time-consuming,’ said Stratasys’ Healthcare Vice President Osnat Philipp. ‘The J5 DentaJet advances the full digital transformation of dental modelling with the potent combination of automation with accuracy. The system runs largely unattended and you can even produce a build tray with a wide variety of different models using several different materials. It’s a productivity monster.’
The J5 DentaJet is launching with a full range of resins tailored to meet the needs of the dental industry. Available biocompatible resins include a clear resin, VeroGlaze opaque white for temporary in-mouth placement, and a clear and flexible resin. In addition, Separator digital material automatically coats models to make it much easier to separate the acrylic device from the model and remove wax and residue. Other available resins include VeroDent PureWhite, and CMY resins for colour.
