We’ve had a desktop 3-D model printer for more than three and a half years, and it’s been convenient for a variety of routine procedures. Recently, we were introduced to the new cara Print 4.0 by Kulzer Dental. The digital light projection (DLP) technology offers exceptional accuracy compared to laser light technology and is faster than most other DLP printers.
Laser-based printers are usually slower, as they have to trace each layer, point for point. DLP technology with the cara Print 4.0 can project an entire layer in a single flash and achieve a finer level of detail. This allows for greater precision, speed, and homogeneous surfaces.
The cara Print 4.0 has automatic speed adjustment to adapt to the accuracy requirements of your material and product you want to produce. The ability to vary layer thickness from 30 to 150 μm allows for optimal balance of accuracy and speed. This allows you to optimize the process. Therefore, if you don’t require high accuracy for a specific appliance, you can increase layer thickness and reduce build time.
Some resins for 3-D printers come in cartridges, which can often prevent you from selecting the materials of your choice (closed-system), making it overall less convenient. Cartridges are less efficient and require more maintenance and extra care when cleaning. The cara Print 4.0 is an open system and cartridge-free for easy cleaning and maintenance.
This printer offers a variety of appliance options, including occlusal guards, surgical guides, diagnostic models, acrylic teeth, and full dentures. I was able to print a full set of upper and lower dentures, including teeth, in less than two hours. Designed properly, these can serve as final or transitional dentures. The printed denture system by Kulzer offers six denture bases and six teeth shades, all FDA-approved.
The cara Print 4.0 is a revolutionary printer that is fast, efficient, and versatile. I’d definitely recommend taking a close look at it if you’re interested in a digital workflow.
