The desktop 3D printers on the market today fall into two groups: expensive and high resolution or less expensive but with sub-standard printing quality. We designed the MoonRay to bridge this gap and bring high-quality printing capabilities to an affordable desktop 3D printing unit.
We tapped the top engineering, 3D printing and industrial design talent to create the MoonRay, a printer that combines high printing resolution, a small and sleek form factor and a price tag that’s within reach for artists, designers, businesses and hobbyists who are serious about creating high-quality, 3D-printed projects.
The MoonRay's UV projector allows for pin-point accuracy when creating your project. The MoonRay can print features as fine as 100 microns, making your finishing touches easy and less time consuming than with other 3D printers.
3D printing is the process of printing 2D layers over and over, stacking them on top of each other. The thickness of those 2D layers is the Z resolution. The intricacy of features on those 2D layers is defined by the XY resolution. It's important to know the difference when you're evaluating 3D printers. The MoonRay's Z resolution is 20 microns and the XY resolution is 100 microns. This allows you to produce highly intricate designs with ultra-fine details.

UV DLP Light Source
3D printing resin requires UV light for proper curing. Other DLP 3D printers use regular projectors which produce visible light, but not pure UV light. The advantages of the UV LED projector in the MoonRay are in the resolution and curing process. The MoonRay’s UV projector, RayOne, was custom designed with some special qualities:
- Perfect light spectrum: The resin used for 3D printing cures under light with a 405nm wavelength. The RayOne uses exactly that wavelength to cure our resin. The light spectrum of a regular projector ranges from 350nm to 700nm, which means most of the output light is wasted. The wasted light will generate heat and negatively affect the resin quality, lowering the resolution of the printed part. Our custom-built projector allows you to get real 100-micron resolution.
- Runs cool and quiet: Utilizing a UV projector allows the MoonRay to avoid any overheating and makes it much quieter than other 3D printers.
- Long lifespan: The RayOne’s 50,000-hour lifespan means you won’t have to replace the bulb.
Grid Calibration for Uniform Output
The light intensity of each area of a projector is different. It is normally dimmer in the corners and brighter in the center. To create a part with higher accuracy, the intensity of the entire projecting area should be uniform. We measured the intensity of the light in a grid for our UV projector (RayOne) and calibrated the projecting image to have a uniform output. This enables you to achieve repeatable results from all parts of the platform. It also ensures the MoonRay can accurately print flat surfaces and straight lines.
Intuitive and Honest Design
When we designed the MoonRay, we aimed to strip away the clutter and keep things as simple as possible. As a result, the MoonRay has no moving parts that aren’t essential to the printing process. This simplicity allows the MoonRay to keep running smoothly over time.
The MoonRay is small (15” x 15” x 20”), perfect for sitting on your desk or work area. You have your choice of two colors, Cosmic Gray or Lunar White, to make sure your MoonRay matches your style.
Plug and Print - Seriously
The MoonRay was designed to be easy to set up, easy to understand and easy to use. There’s no assembly required - just plug and print. After printing, simply take off the top (attached by magnets instead of hinges to save space) and grab your finished product.
Automatically Generates Supports
When you’re designing your project, you won’t need to worry about creating an elaborate support system. The MoonRay’s RayWare software will do that for you. Our advanced support-generation algorithm is optimized to make strong, correctly placed supports without wasting material.
Our software will also slice your model. You provide the STL file and RayWare will do the rest.
Surface Smoothing Technique
RayWare features an anti-aliasing algorithm that significantly smoothes the surface of your finished product.
3D printing normally has a stair-stepping issue because layers are stacked together to build 3D parts. In our software, we give you option to smooth out the stair-stepping so you can have smoother surface straight from the printer.
Large Build Platform
The MoonRay may have a small footprint, but the build volume is surprisingly large for such a small machine. Your creativity shouldn’t be limited by the platform of your printer. The MoonRay has a build volume of 5 x 3.2 x 9 inches.
Our Custom Resins
We’ve developed a variety of resins for the MoonRay printer, including a high-resolution orange resin and a high-volume green resin. We also have a castable resin, perfect for jewelers who do lost-wax casting. We’ve priced the resin to be affordable (even after the Kickstarter is over), so you can continue to print to your heart’s content.
Long-Lasting Resin Tank
Most resin 3D printers have a consumable resin tank that needs changing after every 1-2L of resin printed. We designed the MoonRay’s resin tank to last, so there’s no more replacing your printer’s resin tank or changing the PDMS layer. We've put an end to the frustrating PDMS process, so you can focus on making great prints without worrying about costly maintenance of the resin tank.
With the high resolution and easily removable supports, this is a jewelry maker's dream come true. Our castable resin makes it easy and affordable to start creating your jewelry with the MoonRay.
Industrial Designers and Engineers
The MoonRay has many uses that will make life easier for industrial designers and engineers. Use it to print parts for a mechanical experiment or to prototype your next product. You can also print parts to make appearance models for presentations. Our resins accept primer, so you can paint all of your printed parts.
You’ll find that it’s easier than ever to create character figures and costuming parts with the MoonRay.
Whether you’re dabbling in mixed media or even developing your latest cosplay creation, the MoonRay will deliver the finest resolution and produce projects that are ready for your finishing touches.
3D printing allows architects to create scale models of buildings without the constraints of traditional modeling material, like balsa wood or cardboard.
Fashion and Accessory Designers
For toy designers, 3D printing is a fantastic way to create toys of every shape and size. Whether you want to make detailed figurines or modular toys, the MoonRay can help you do it.
The MoonRay will make your other technical toys jealous. The small footprint fits easily into your workshop and the large build volume and fine resolution will let you create toys, gadgets and pieces for all types of projects.
We’re a new company with a product we believe in. In order to produce this printer at a high volume and deliver it at the price we’ve set, we need funds to ramp up production. Backing our Kickstarter helps us ensure everyone has access to the most advanced desktop 3D printing technology available.
Further Research & Development
We have some neat plans in the works for the MoonRay and are currently working on developing additional resins. Kickstarter funding will help keep the momentum going with our R&D team.
Early backers get can a MoonRay with early delivery at a special low price. The longer you wait to back the project, the longer you’ll have to wait to receive your MoonRay.

Risks and challenges
The largest challenges for a complex project like this one are manufacturing and timing. We’ve seen from other Kickstarter campaigns that it can be difficult to deliver everything on schedule, especially when the project is extremely successful.
We have experience on our side, though. SprintRay has a manufacturing base in China, so we already have a team in place. This is a different market with different challenges and we will be approaching the manufacturing process carefully to avoid any potential bumps in the road during Kickstarter reward production.Learn about accountability on Kickstarter
