PROCESS PLANNING
Machining & Finish
RapidMfgPro reviews geometry, tolerance, material behavior, finish, quantity, and inspection requirements before matching the project with suitable manufacturing resources.
CNC Turning
Useful for clear rings, tubes, lenses, knobs, and inspection components.

Designing Parts in PMMA (Acrylic)
Use the following points as an early DFM checklist. Final recommendations depend on part geometry, stock form, quantity, finish, and functional requirements.
Request a DFM ReviewUse generous internal radii
Sharp corners can concentrate stress and promote cracking.
Protect optical faces
Identify surfaces that must remain scratch-free during machining and handling.
Allow finishing stock
Reserve material for polishing on critical transparent edges.
Avoid aggressive fastening
Use washers, controlled torque, and suitable clearance around screws.
