Digital Manufacturing Equipment
Posted May 14, 2013, Published 2013-05-01
The proliferation of digital technologies continued to flourish at the IDS, with more and more digital manufacturing solutions that enable users to address a greater number of applications and work with a larger range of materials. In addition, the 3D printing market continues to expand.
Zubler—known for its handpieces, suction systems and ovens—has entered the digital market with a milling solution marketed through its new CAD/CAM division, Dental Concept Systems. The IDS was the European launch of the system, which includes Dental Softworks CAM software, Zubler VARIO SCAN™ strip light scanner and the five-axis DC5™ milling machine.
The DC5 offers dry milling of zirconia, alumina, PMMA, composite, splint resins, wax, cobalt-chromium and model materials, as well as wet milling of cobalt-chromium, titanium and glass ceramics. Designed specifically for dental applications, it also features an optional seven-disc changer, two separate cooling tanks and a built-in suction system that allows you to switch between wet and dry milling in under five minutes. The company has also opened a new office in Santa Ana, CA, that offers training and a back-up milling facility.
Roland featured new enhancements to its DWX-50 five-axis mill including fixtures to support pin-type zirconia, resins and nano ceramics and tooling options for a variety of applications, including the production of models, custom abutments and zirconia implant bars. Attendees also had the opportunity to preview Roland's DWX-4, a dry mill designed for smaller labs that's scheduled to launch later this year.
DATRON AG has a new model D5 milling machine that features linear glass scales that provide precision (+/- 5 microns) and thermal stability, making the system even more suited for large-span work, custom abutments (including implant interface and screw channel machining) and implant-supported, grade-5 titanium frameworks and bar structures. DATRON Dynamics, the company's North American representative, will have this model available this summer.
The company has also integrated a preform abutment milling solution that uses FDA-approved blanks, allowing labs to manufacture their own custom titanium abutment designs in as little as 15 minutes each. The preform fixture fits directly into the D5 blank holder and allows for the milling of up to six abutments in a single cycle.
In the additive manufacturing arena, 3D Systems launched the new ProJet 3510 MP and DP printers; the MP is the dental model printer and the DP is for printing waxups. Both printers have the same inkjet technology and no-touch, melt-away wax support system as the company's previous ProJet systems but with a new look and touchscreen interface. The company also introduced a new material for printed models, VisiJet® Pearlstone™. "It's a thermal/UV combination material that's lightweight and has a matte finish, making it look and feel like a stone model. It offers excellent accuracy, detail and definition," said Lee Dockstader, Vice President, Business Development.
The company also showed two solutions for surgical guide printing: one solution is based on inkjet technology and the other uses SLA laser printing technology.
Orthodontic laboratory owners took note of the DigitalWax® 020D, DWS's new desktop additive manufacturing system for orthodontic applications. The 3D printing system produces orthodontic models, surgical guides and positioning trays quickly and accurately. On the heels of its Chicago launch of the dfab™ desktop printer, DWS also showcased dfab Chairside, its first digital printer designed for the dental office, which enables dentists with an intraoral scanning unit to print temporaries in as little as 20 minutes.
The company's new light-cure provisional material, Temporis® , is available in six shades, and its new DigitalWax™ material line includes DS transparent resins for surgical guides and RF casting resins for C&B and partial frameworks.
Stratasys also launched a new 3D printer, the Objet30 OrthoDesk for manufacturing models for orthodontic appliances including clear aligners and retainers and delivery and positioning trays. It's specifically designed for smaller labs and orthodontic offices. The company's new material, MED690 is the second-generation version of the Objet VeroDent, an acrylic-based photopolymer; it's more opaque than VeroDent and offers higher-resolution details.
