Materials, Tolerances & Process Limits
We work with engineering-grade polymers for prototypes, replacement parts, functional components, and production runs. Materials and processes are selected based on how the part needs to perform — not simply what's easiest to print.
Structural & Filled Polymers
Brackets, fixtures, motor mounts, and other components that need strength, stiffness, and dimensional stability.
High-Temperature Materials
Components that need to withstand elevated temperatures while maintaining their shape and performance.
Outdoor & Chemical-Resistant Materials
Components exposed to UV, solvents, fuel, cleaning chemicals, and other demanding conditions.
Flexible Elastomers
Gaskets, bushings, dampers, grippers, and other components designed to flex, compress, or absorb impact.
Fit & Form Prototypes
Economical prototypes used to check fit, form, clearances, and design before moving to a production material.
We keep a working stock of filled nylons, structural and outdoor-rated polymers, and elastomers on hand for common applications. If a project calls for something outside our standard stock, we can source the appropriate material for the job.
One-off prototypes through low-volume production and full production runs. Repeat orders use the same validated setup for consistent, repeatable results.
Heat-set inserts, tapped threads, support removal, bead blasting, and vapor smoothing are available where the material allows.
Parts larger than the available build volume can be split, keyed and bonded, or redesigned as a bolted assembly for the finished application.
Some parts call for more than additive manufacturing. We work with trusted partners to bring in the processes and components your project needs.
