Prototype materials.

Material selection for prototyping — fast availability, machinability, cost. Lower priority on production-grade properties unless functional prototype.

01 · Key principles

Key principles.

CNC aluminum 6061

Standard prototype

Most common prototype material. Cheap, fast, machinable.

CNC ABS

Plastic prototype

Bar-stock ABS approximates injection ABS for prototypes.

CNC acetal

Wear surfaces

Bar-stock acetal for wear-resistant prototypes.

SLA photopolymer

High detail

Resin SLA for highest detail visual prototypes.

SLS PA12

Functional prototype

SLS nylon for functional prototype. Good mechanical.

FDM ABS

Lowest cost

FDM extrusion for low-cost concept prototype.

Urethane casting

Production-like

Silicone-cast urethane parts approximate injection ABS.

Aluminum tooling

Bridge production

5-10K shots from aluminum mold for production-grade prototype.

Sheet metal CNC

Quick fab

Laser-cut + bend sheet metal prototypes from production-grade stock.

FAQ

How to select prototype material?

Match production material family if possible. Use CNC bar stock for plastic prototypes — closer to production injection grade than 3D print.

Functional vs visual prototype?

Functional needs production-similar properties. Visual needs surface finish. Different material choices.

Speed vs quality tradeoff?

3D printing fastest (1-3 days). CNC quality (5-10 days). Each suits different prototype phase.

Material cost in prototyping?

Material cost negligible vs labor for one-off parts. Don't under-spec material to save trivial amount.

Cosmetic prototype materials?

SLA + paint for highest visual. CNC + brushed/anodize finish for premium look. Choose per intent.

Iterative refinement?

First iteration cheap material/process. Final iteration production-representative material. Different priorities each phase.
