Rapid Prototyping for Custom Precision Parts
JADMAKE helps engineering teams turn CAD files into functional CNC prototypes for fit, function, assembly and design verification. Each RFQ is reviewed for manufacturability, material choice, tolerance risk, finishing needs and practical delivery planning before machining begins.

Rapid Prototyping Design Guidelines
State the Prototype PurposeTell us whether the prototype is for appearance, fit, assembly, functional testing, thermal testing or buyer approval.
Mark Critical FeaturesOnly dimensions that affect fit, sealing, alignment or test results should receive tight prototype tolerances.
Keep Internal Radii RealisticSharp internal corners usually require EDM or design changes; CNC prototypes need cutter-radius-friendly corners.
Avoid Unnecessary Cosmetic FinishEarly functional prototypes often do not need full cosmetic finishing unless appearance is part of the test.
Choose Production-Like MaterialUse the intended production material when strength, heat, threads, weight or finish behavior must be validated.
Plan the Next RevisionIf the prototype may change after testing, separate must-have features from areas likely to be revised.
Include Assembly ContextMating parts, screw size, inserts, gasket faces and clearance needs help avoid avoidable prototype rework.
Upload 2D Notes With 3D CADThe 3D model defines geometry, while the 2D drawing should clarify tolerances, threads, finish and inspection needs.
FAQ
What is CNC rapid prototyping?
CNC rapid prototyping uses CNC machining to produce functional metal or plastic samples for design validation, fit checks, testing and buyer approval.
How many prototype parts can JADMAKE make?
Prototype projects commonly start around 1-20 parts, depending on geometry, material, finish and inspection requirements.
When should I choose CNC prototyping instead of 3D printing?
Choose CNC prototyping when the part needs production-like material, tighter dimensional control, surface finish, threads, strength or functional testing.
What files are needed for a CNC prototype quote?
Send 3D CAD files, 2D drawings, material, quantity, critical tolerances, finish requirements and the purpose of the prototype.
Can prototypes be finished or anodized?
Yes. Surface finishing can be reviewed with the prototype material, cosmetic requirements and tolerance impact.
Can a prototype move into low-volume production?
Yes. Once the design is validated, JADMAKE can review fixture strategy, inspection requirements and repeat production planning for low-volume orders.
