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.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
