Functional Parts for Urgent Robotics Builds
We 3D print custom plastic prototype parts in-house using FDM, SLA, and SLS technologies.
Fast DFM feedback, engineering-aware material choices, and repeatable small batches for robotics builds, tests, demos, pilots, and design revisions.
Eligible rush jobs can move into production the same day.
FDM and SLA typically 1-3 business days. SLS typically 2-4.
Next-day rush available for eligible jobs
We treat files as confidential
Built Around Production Start, Not Just Quoting
A fast quote does not help much if parts sit in a queue. We help robotics teams turn approved CAD files into a real print job quickly, with process and material review before the job moves into production.

Upload models, choose process, material, color, quantity, and lead time, then place the order online
Avoid Slowdowns
Our in-house FDM, SLA, and SLS production gives urgent jobs a clearer path forward when your current solutions may be slower
Keep the Build Moving
Get the plastic parts needed for test builds, assembly checks, demos, and revisions, so the next build cycle is not waiting on missing parts
Made for Robotics Build Cycles
Robotics parts need to be handled, assembled, checked for fit, tested, used in demoes, and sometimes revised. We support fast build cycles so waiting on plastic parts does not slow engineering work.
Test Builds
Parts for assembly checks, validation work, and engineering iteration
Assembly and Fit Checks
Plastic parts for checking clearances, mounting points, covers, brackets, and real-world fit
Demos and Pilots
Functional parts for demos, pilots, and customer-facing build milestones
Specialty Materials
Flexible, tough, heat-resistant, carbon-filled, and other engineering plastics for demanding builds
Design Revisions
Updated parts printed quickly so the next version can be checked and revised
Repeat Quantities
Small batches for teams that need more than a one-off prototype
