The MoonRay S High Resolution DLP 3D Printer from SprintRay Will be Going Through Clinical Testing Soon




Shhhhhhh… do you hear that?  That noise you hear is the sound of an approaching change in technology in dentistry.

Digital 3D printing is coming to dentistry and it is coming in a big way.  In the past 2-3 years we’ve seen its arrival in a lot of different ways and it is only getting better.

3D printing can be used for models, occlusal guards, surgical guides, stents, even dentures.  You can even print in materials that can be used in a burnout oven to perform similar to the lost wax technique, which “sort of” allows for digital printers to be involved in the fabrication of permanent prostheses.  However, no one yet has come cup with a material that can print a permanent restoration… not yet anyway.

The technology promises a lot for our profession and not in some faraway future, but right now.  There are several companies that have entered the dental space and are looking to gain market share with reliable, accurate, and easy to use hardware.  One of those companies is SprintRay.
This week I’m going to be installing and then I’ll be using their MoonRay 3D printer.  The device is incredibly accurate in its printing due to the fact that the light curing unit is a UV DLP projector named RayOne.  It virtually eliminates distortion that is a problem with regular DLP and laser SLA 3D printing.  There is an array of tiny mirrors that reflect the light and cure with uniform precision.  If you don’t have the best quality DLP projector, you don’t get a good quality 3D rendering.
Here are some specs:

RAYONE PROJECTOR TECHNICAL SPECIFICATIONS
  • 100 Microns XY Resolution (Pixel Density)
  • 1280 by 800 Pixels
  • Glass + Polycarbonate Lens Construction
  • Texas Instruments DLP Chip
  • 405nm Blue-Violet Light
  • LED-based Light Source
  • 50,000 Hours Expected Lifetime
  • Machined Aluminum Structure
MOONRAY S TECHNICAL SPECIFICATIONS
  • Build area: 13 x 8 x 20 cm
  • Layer Thickness Options: 20 x 50 x 100 Microns
  • Minimum Feature Size: 100 Microns
  • Print Speed: 1 in/hour at 100 Micron z height
  • Wireless: LAN or Ad-Hoc WiFi b/g/n
  • Wired Connectivity: LAN via Ethernet
  • Unit Size: 38 x 38 x 50 Cm
  • Unit Weight: 14 kg
I’m excited to begin integrating this system into our clinical workflow including our CBCT 3D x-ray unit, digital impression acquisition unit, and now the MoonRay 3D printer.

I’ll be putting the device through some testing in the office and have it work on a variety of projects for me.  I’m planning on his evaluation taking a while, but rest assured that I’ll be back with some thoughts and opinions after I’ve taken adequate time to experiment and test.  The MoonRay is available from SprintRay.
