Shenzhen Alu Rapid Prototype Precision Co., Ltd.

Estimating CNC prototyping costs—especially when working with high-end Shenzhen-based firms like Alu Rapid Prototype—requires looking at the project as an "iceberg." The raw material is only the tip; the real drivers are machining time and setup.

In 2026, a standard CNC prototype typically ranges from $50 to $500 per part, but complex or large aerospace-grade components can easily exceed $1,000.

1. The Core Cost Formula

Most precision shops use a variation of this bottom-up estimation:

Total Cost = Material Cost + (Machining Time X Machine Hourly Rate) + Setup Fee+ Finishing

A. Material Cost (15-25% of total)

Calculated by the volume of the raw stock "block" (billet), not just the finished part.

Aluminum 6061: ~$5-$10 per kg.

Stainless Steel 304: ~2-3x more than aluminum.

Titanium: ~$100-$200 per kg.

B. Machine Hourly Rates (2026 Benchmarks)

The type of machine required dictates the hourly burn rate:

3-Axis Milling: $30 - $80/hr (Best for simple brackets/plates).

4/5-Axis Machining: $80 - $200/hr (Necessary for complex, organic geometries).

CNC Turning (Lathe): $40 - $100/hr (Best for cylindrical parts).

C. Setup & Programming (The "Hidden" Cost)

For a single prototype, setup is often 40-60% of your bill. This covers CAM programming,fixture building, and "First Article" testing. 

Simple Part: $50 - $150

Complex Part: $200 - $500+

2. The "Multiplier" Factors

Design choices act as multipliers on the base cost. To estimate accurately, identify if your part has these

3. Post-Processing Estimations

If you need the part to look "retail-ready" (as is often the case with Alu Rapid Prototype'saesthetic parts):

Bead Blasting: $5 - $15 per part.

Standard Anodizing: $10 - $30 per part (note: minimum batch charges often apply).

Hand Polishing/Mirror Finish: $50+ (very labor-intensive).

4. Prototyping vs. Batching (The 2026 Shift)

With the rise of automated quoting, the "price gap" between 1 and 10 units has shrunk.

 1Unit: $300 (Total)

 10 Units: $650 (Total) - Unit price drops from $300 to $65.

Tip: If you suspect you'll need more than one prototype for testing, ordering 3-5units upfront is almost always more cost-effective than ordering one now andanother in two weeks.
