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.

The environments frontier AI trains on, and the agents that do the recurring work
Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.
