Global, diverse data collection at scale for training, with privacy and security vetting on every dataset.
Belt 3D printers for automated additive serial production
The One Pro prints onto a moving belt rather than a fixed plate, so objects travel continuously and print length is practically unlimited — including multi-meter profiles.
Printing at an incline allows complex overhangs with significantly less support material, improving both part quality and material efficiency.
Finished parts leave the build area automatically, so the printer can run batches back-to-back without an operator clearing the bed between jobs.
Ready-made bundles for orthopedic insoles (scanner, software, printer, material) and for meter-long extrusion profiles for prototyping and custom parts.
