From part design to production

We take your part from design review and mold development through sampling, process validation, and final production, with each stage building on the last.

01
DFM Review
Reviewing your design

We review wall thickness, draft, parting lines, ribs, bosses, and undercuts before tooling. Required changes are identified to improve moldability and production quality.

Cadlete Designs helped me design a 3d model for a quite complex project: the Lightsaber. There were a lot of design decisions which mattered here, and they executed them perfectly! After 3d printing everything worked out well and connected well. The response time is phenomenal, after asking for fixes they were done the next day or even sometimes the same day. They also provided nice explanation videos each time to explain the design choices made. Would definitely recommend!
