3D printer maker Stratasys has announced the launch of its latest PolyJet multi-material 3D printer.
The J5 DentaJet was specially developed for dental applications and can deposit up to five different biocompatible resins at the same time, including a carrier material. This allows clinicians to 3D print mixed trays of high-precision dental parts in one job, including rigid implant models, soft gingival masks and functional surgical guides. Since several different components and materials are required for each prosthesis or implant shell, the J5 DentaJet was ultimately designed in such a way that multiple 3D printers and print jobs are no longer required.
“Dental and orthodontic models are increasingly relying on 3D printing, but the process has remained too manual and time-consuming,” explains Osnat Philipp, Vice President Healthcare at Stratasys. “The J5 DentaJet advances the full digital transformation of dental modeling with the powerful combination of automation and accuracy. The system runs largely unattended, and you can even make a construction drawer with a variety of different models from different materials. It’s a productivity monster. “

PolyJet 3D printing with Stratasys
The PolyJet series is Stratasys’ proprietary line of material jet 3D printers, a technology the company is industry leader in. The flagship of the J8 series includes the full-color printer J850 Prime 3D, the J850 Pro in the mid-range and the J826 in the entry-level range. With a maximum model size of 255 x 252 x 200 mm, the J826 is compatible with Stratasys’ extensive suite of rigid, transparent and tear-resistant materials for technical applications.
Looking at some of the company’s other dental 3D printers, the J700 Dental is designed to make clear aligners. The J720 Dental enables 3D printed orthodontic 3D printed components. and the J750 Digital Anatomy is mimicked to create lifelike medical models that mimic bone and tissue.

The J5 DentaJet 3D printer
If Stratasys estimates are correct, the addressable market for 3D dental printing is currently around $ 1 billion. With so many manufacturers entering the market, the J5 DentaJet is conquering a niche in the high-volume, realistic model segment that was previously only possible with inefficient wax materials.
The new 3D printer has a maximum part size of 140 x 200 x 190 mm and a construction area of 1,174 cm², so that the system can print up to 41 implant cases per day with just two compartments. According to Stratasys, this means the machine can produce at least five times as many polymer dental components as its competitors while taking up just 4.6 square feet of floor space.
The system’s multi-material and multi-color printing capabilities are expected to enable a wide range of part types including implant and orthodontic models, removable denture frameworks, try-ins, indirect adhesive floors, and even custom impression trays. In addition to the 3D printer, Stratasys is also launching a range of new clear, white, and flexible biocompatible resins. The system will also be compatible with the company’s previously released VeroDent PureWhite and CMY materials.
NEO Lab, an orthodontic laboratory in the USA, has already had the opportunity to test the J5 DentaJet. Christian Saurman, CEO and co-owner of the company, explains: “We produce 600 orthodontic devices every day. The DentaJet 3D printer is easy to use, can create many models in a single print, and we don’t spend a lot of time post-processing the models after they leave the device. Our models move from printer to production faster than ever before. “
