3 d打印机制造商Stratasys宣布推出其最新的多物质PolyJet 3D打印机。
Developed specifically for dental applications, theJ5 DentaJet最多可一次沉积五个不同的生物相容性树脂，包括支撑材料。因此，它使医疗专业人员能够在一项工作中使用高精度牙科零件的3D打印托盘，包括刚性植入物型号，软牙龈口罩和功能性手术指南。对于每个义齿或植入物需要几个不同的组件和材料，J5 Dentajet最终旨在消除对多个3D打印机和打印作业的需求。
“Dental and orthodontic models have been growing their adoption of 3D printing but the process has remained too manual and time consuming,” explains Stratasys’ Healthcare Vice President Osnat Philipp. “The J5 DentaJet advances the full digital transformation of dental modeling 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.”
PolyJet 3D printing with Stratasys
The PolyJet range is Stratasys’ proprietary line of material jet 3D printers, a technology in which the company is an industry leader. The flagship J8 Series includes the full-color J850 Prime 3D printer, the mid-level J850 Pro, and the entry-level J826. With a maximum model size of 255 x 252 x 200mm, the J826 is compatible with Stratasys’ extensive suite of rigid, transparent, and tear-resistant materials for engineering applications.
Looking at some of the company’s other dental-specific 3D printers, theJ700 Dentalis designed for clear aligner production; theJ720 Dental启用全彩3D打印正畸组件；和J750 Digital Anatomyis indented for the production of bone and tissue-mimicking life-like medical models.
The J5 DentaJet 3D printer
If Stratasys estimates are anything to go by, the addressable market for dental 3D printing currently stands at around $1 billion. With so many manufacturers now entering the market space, the J5 DentaJet is carving a niche for itself in the high-volume realistic model segment, which was previously only possible using time-inefficient wax materials.
新的3D打印机的最大零件尺寸为140 x 200 x 190mm，构建面积为1,174厘米，这使该系统每天只需两个托盘即可打印多达41个植入物。根据Stratasys的说法，这意味着该机器的聚合物牙科组件至少可以产生五倍的竞争对手，同时仅需要4.6平方英尺的地板空间。
The system’s multi-material, multi-color printing capabilities are expected to facilitate a whole host of part types, including implant and orthodontic models, removable denture frameworks, try-ins, indirect bonding trays, and even custom impression trays. Alongside the 3D printer, Stratasys is also launching a number 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 lab in the U.S., has already had a chance to beta-test the J5 DentaJet. Christian Saurman, CEO and co-owner of the company, states, “We produce 600 orthodontic appliances every day. The DentaJet 3D printer is easy to use, can produce a lot of models in a single print, and we don’t spend much time post-processing the models after they come out of the machine. Our models go from printer to production floor faster than ever.”
