3D printing that's safe, fast, and completely automated.


Running a factory of 3D printers is dangerous and expensive.

... but what if it wasn't?


We solve the biggest problems with 3D printers.

3D printers aren't appliances. Skilled, technical workers need training to safely operate and maintain printers between each and every print. This takes time and costs a lot of money.

3D Printers Can Cause Injuries

Moving components, high-temperature parts, and the need for sharp tools to remove completed prints from the build area leads to injuries.

Injuries prevent 3D printing adoption. Consumers don’t want these printers in their homes, businesses can't have them in the office, and 3D printing services are expensive because they price in the operating costs. The world needs an automated printer to break this barrier.


3D Printers Are Slow

A print the size of a coffee mug can take as long as 8 hours!

3D printing adoption requires speed. Engineers and designers need to iterate within the same business day, and consumers hoping for custom-manufactured goods want to get them quickly. Printing services are constantly backlogged, because their current printers simply can't deliver.


3D Printers Are Inefficient

It takes a shockingly large printer to print something relatively small.

You need a lot of 3D printers to get work done. Large prints need to be split into multiple pieces and assembled, and you need several printers working simultaneously to get it done quickly. The value of any one printer on the market just isn't that great.


The R3 Printer

The R3 Printer is the next step in additive manufacturing. Designed solely with automation and reliability in mind, it's a standard-setting machine that unlocks the future we've all been promised.

The R3 Printer is Safe

Automation eliminates the need for operators to engage with the printer. Without the need for hands-on administration, there's no opportunity for injury.

Operators of an R3 Printer won't get burned, cut, or scraped.

Prints automatically eject when they're complete, eliminating the need for sharp tools in the confined space inside a 3D printer. 


The R3 Printer is Fast

With a patent-pending and completely reimagined print head that's 84% lighter, we put the "rapid" back in "rapid prototyping".

The R3 Printer prints 90% faster than competing 3D printers.

The R3 Printer also has Active Overheat Prevention™, a proprietary system that detects print head overheating and immediately pauses the printer, eliminating the need for monitoring and intervention by an operator.

The R3 Printer is Efficient

Coupling thoughtful chassis design and the R3 Printhead™ which sports a 75% smaller footprint than the competition, leads to unbeatable results.

The R3 Printer has a 200% increase in build area.

Factories and businesses alike can print full-size parts and vastly reduce the amount of file-splitting and reassembly in their workflows, dramatically reducing overhead costs.
