From concept to finished parts

Every project runs through the same three steps — scoped on their own, or end-to-end as one pipeline. A short technical conversation is enough to get to a manufacturing-ready 3D model; prototyping and production then run on the same manufacturing network, from single parts to medium-series runs.

Step 01

Concept & CAD

A short technical conversation to capture what the part needs to do, followed by concept sketches and full parametric CAD — tolerances, GD&T, and assembly detail included. What feels like one step delivers a manufacturing-ready 3D model.

What this includes

  • Technical intake conversation
  • Concept sketches & feasibility check
  • Parametric CAD in SolidWorks or Fusion 360
  • Tolerance stack & GD&T
  • Deliverables: native CAD, STEP/IGES, drawings

Step 02

Prototype

Your design becomes a physical part within days — CNC-machined or 3D-printed in the material that matches its function — iterated until fit and performance are right.
