Estimated Prototype Cost

Per Unit (Low)

$15.00

Per Unit (High)

$40.00

Total Range

$15.00 – $40.00

Estimated fdm 3d printing prototype: $15.00 – $40.00 per unit for 1 unit(s). Total: $15.00 – $40.00.

Key Factors

•Single-unit prototype — no quantity discount applies. Setup and programming costs dominate.

Example

A medium-sized CNC-machined aluminum bracket, 3 units, basic finish:

Estimated cost: $60.00 – $150.00 per unit. Total: $180.00 – $450.00

Frequently Asked Questions

When should I use CNC vs. 3D printing for prototypes?

CNC machining is better when you need tight tolerances, specific production materials (e.g. aluminum), or a surface finish close to production. 3D printing is faster and cheaper for form/fit testing, especially for complex geometries that are difficult to machine.

How many prototype units should I make?

Typically 1–3 units for form/fit checking, 5–20 for functional testing or user trials. More units mean lower per-unit cost due to setup amortization, but don't over-order if the design may change.

Does the cost include design or CAD work?

No. These estimates cover manufacturing only. If you need design services, 3D scanning, reverse engineering, or DFM optimization, those are typically quoted separately.

What is Vacuum Casting and when should I use it?

Vacuum casting uses a silicone mold to produce small batches (10–30 units) of polyurethane parts. It's ideal for bridging between 3D-printed prototypes and injection-molded production parts, especially when you need material properties close to production plastics.

How do I reduce prototype costs?

Increase quantity to amortize setup costs, choose lower-cost finishing (as-printed instead of professional), simplify geometry, and use standard materials. Also consider whether you really need all units finished to the same level.
