We had a look at the new MoonRay S desktop 3D printer from SprintRay.
The SprintRay MoonRay S is an evolution of their previous product, the MoonRay, which had an extremely well received crowdfunding campaign, raising over USD$400,000. Since then they’ve been successfully producing the machines, but now have developed new versions.
The MoonRay “D” model is designed for dental use, but now they’re announcing the MoonRay “S” model. Apparently the “S” stands for “fun” as it is designed to be an “all in one” system that is applicable to hobbyists, inventors and artists.
It’s a resin machine, to be sure, using a DLP-style projection system to cure the photopolymer. But there’s a big difference between this machine and others: SprintRay has developed a custom DLP projector for the machine, and has not simply co-opted an existing visual DLP projector for this use. The difference means they can tune the light to precisely the correct wavelengths for optimum curing of the liquid resin. Prints can be more accurate as excess off-wavelength energy does not heat up surrounding resin.
The print quality from the MoonRay S is awesome. This print was made with one of SprintRay’s standard resins, which are recommended for use. I believe it’s possible you could use alternative resins in the machine, but you’d do so by risking the quality of the output, and that’s what this machine is all about.
Equipped with multiple improvements based on user feedback on previous models, the new model S is equipped with WiFi networking and is priced at USD$4,000.
Not bad for a company that started with an idea by two PhD students from Los Angeles.
