Materials, rapid prototyping, and CNC design notes from the JS Model engineering team.
Nylon Prototypes: Moisture, Fit and Process Selection
Choose a nylon prototype process and define grade, moisture condition, mating features, and inspection before testing fit or wear.
Rapid Prototyping: Match the Process to the Test
Compare CNC, sheet metal, casting, and printed prototypes by test purpose, material fidelity, geometry, and production handoff.
Large CNC Parts: Plan Stock, Setups and Inspection
Prepare a large-part CNC RFQ with stock dimensions, handling constraints, tool access, datum requirements, and an inspection plan.
Accuracy in Large CNC Parts: Datums and Distortion
Control large-part machining risks by defining functional datums, clamping conditions, material removal, and measurement conditions.
CNC Bicycle Components: Design for Fit and Repeatability
Review CNC bicycle components for mating interfaces, material condition, tool access, finish, inspection, and prototype validation.
