What a 5-Axis Prototype Costs and How to Keep It Down

September 30, 2026

A 5-axis prototype quote can surprise you. One part costs several hundred dollars, and five of the same part cost not much more. Once you see what the shop is paying for, the number makes sense, and you can change a few things on the drawing to bring it down.

This guide breaks a prototype quote into its parts. The dollar figures are rough orientation for machined aluminum parts in North America and Western Europe. Rates vary widely by region, shop size and how busy the shop is. This guide is part of our wider look at CNC prototype cost, from the first quote to the order.

The five lines behind every quote

Cost line	Paid	Share on 1 piece	Share on 20 pieces
CAM programming and simulation	Once per order	Large	Small
Setup, fixturing and first-part check	Once per order	Large	Small
Machine time	Per part	Moderate	Large
Material	Per part	Small to moderate	Moderate
Inspection and finishing	Mixed	Small to moderate	Moderate

The first two lines are why prototypes look expensive. They do not shrink when you order fewer parts.

Programming

Before any cutting, a programmer builds toolpaths in CAM, checks them in simulation for collisions and posts code for the specific machine. For a simple 3+2 part this may take an hour or two. For a simultaneous 5-axis impeller or blended port it can take a day or more.

This is the biggest single reason a 5-axis prototype costs what it does. It is also the line most affected by the shop’s experience. A shop that cuts similar parts every week reuses strategies and programs faster.

What you can do: send a clean STEP file, not a mesh. Avoid tiny fillets and chamfers that do not matter for function. Each one is another toolpath.

Setup and fixturing

A production part gets a fixture designed for it. A prototype does not. The shop holds it in a vise, soft jaws or by leaving a tab of extra stock that is cut off at the end. Then it indicates the part, sets tool lengths and checks the first cut.

On a 5-axis machine this usually happens once, because the tool reaches most faces in one clamping. On a 3-axis machine it may happen three or four times.

What you can do: leave a flat, parallel area the shop can clamp on, or allow a small tab witness mark somewhere that does not matter.

Machine time

5-axis machines cost more to buy and run than 3-axis machines, so their hourly rate is higher. As rough orientation, 5-axis time in North America and Western Europe is often quoted somewhere around USD 100 to 200 per hour, and 3-axis time lower. Treat these as ranges, not benchmarks.

Machine time depends on how much material comes off, how hard the material is and how fine the finish must be. Titanium and nickel alloys cut several times slower than aluminum.

What you can do: start from the smallest stock that fits. Use aluminum for early form and fit tests if the alloy does not matter yet.

Material

For a small aluminum part, material is a small share of the price. For titanium, Inconel or PEEK it can be significant. Shops also buy in standard bar and plate sizes, so a part that needs 101 mm stock pays for the next size up.

What you can do: check whether a standard size would work, and ask whether the shop already has suitable stock on the shelf.

Material choice changes both the stock price and the machine time. The multipliers below are rough orientation only, relative to 6061 aluminum for the same part:

Material	Stock cost	Machine time	Notes
Aluminum 6061 or 7075	Baseline	Baseline	Fast cutting, good for early revisions
Brass or free-cutting steel	Moderate	About 1 to 1.5x	Clean chips, stable dimensions
Stainless 303, 304 or 316	Moderate	About 1.5 to 3x	303 cuts easiest, 316 slowest of the three
Titanium Ti-6Al-4V	High	About 3 to 5x	Low cutting speeds, tool wear
Nickel alloys such as Inconel 718	High	About 4 to 8x	Very slow, specialist tooling
PEEK or acetal	Moderate to high for PEEK	About 1 to 1.5x	Heat and burr control, thin walls move

Tolerance and inspection

Tight tolerances mean slower cuts, more tool changes and more measuring. A bore at ±0.01 mm may need a finishing pass and a check on a CMM. The same bore at ±0.05 mm may need neither.

What you can do: put tight tolerances only on the features that mate or seal. Let everything else follow a general tolerance such as ISO 2768 medium.

Inspection is a cost line of its own. A visual check and a few caliper readings add little. A full first article report or a CMM report on every feature can add several hours. Ask for the report level your test actually needs. Typical tolerance bands by material are in the materials table on the home page.

Finishing

Anodizing, passivation, bead blasting and coatings are usually done by outside specialists with their own minimum lot charges. On one part, a finishing step can cost as much as the machining.

What you can do: skip cosmetic finishes on functional prototypes. If you need anodizing for a demo, group several parts into one lot.

Illustrative example: one bracket, three quantities

The numbers below are illustrative, not a quote. They show how fixed and per-part costs combine. Take a 7075 aluminum bracket with features on four faces, cut on 3+2 5-axis. Assume an hourly rate of USD 150, about 2 hours of programming, 1.5 hours of setup and first-part check, 30 minutes of machine time per part, USD 15 of material per part and USD 20 per part for deburring and inspection.

Quantity	Fixed cost	Per-part cost	Order total	Price per piece
1	USD 525	USD 110	USD 635	USD 635
5	USD 525	USD 550	USD 1,075	USD 215
20	USD 525	USD 2,200	USD 2,725	about USD 136

The fixed cost is the same in every row. At one piece it is over 80 percent of the price. At twenty pieces it is under 20 percent. That is why the price per piece falls so fast between 1 and 5 and much more slowly after that.

3+2 or simultaneous: how the cost changes

The choice between 3+2 and simultaneous 5-axis moves the programming line more than any other. A short comparison is in simultaneous vs 3+2 for prototypes. The pattern, as rough orientation:

Cost line	3+2 positional	Simultaneous 5-axis
Programming	Hours	Often a day or more for complex surfaces
Simulation and prove-out	Short	Longer, collision checks on every move
Machine time	Similar to 3-axis once tilted	Can be shorter on contours, less hand finishing
Hand finishing	Needed on blends	Usually less

If every feature on your part sits on a flat face at a fixed angle, ask for 3+2. If the part has blades, blends or freeform surfaces, simultaneous is usually the lower total cost once hand finishing is counted.

Drawing changes that lower the quote

Small design changes remove toolpaths, tool changes and inspection time:

• Internal corner radii larger than you think you need. A radius that fits a 6 mm cutter cuts faster than one that needs a 2 mm cutter.
• Pocket depth within about 4 times the tool diameter. Deeper pockets need long tools, slow feeds and extra passes.
• Standard thread sizes and depths. Odd threads need special taps or thread milling.
• One datum scheme. Dimension features from the same datums the part locates on. Mixed schemes make the programmer guess.
• Surface finish only where it works. An Ra note on a sealing face is useful. The same note on every face adds finishing passes.
• Edge breaks as a general note. One line such as “break all sharp edges 0.2 to 0.5 mm” replaces dozens of callouts.

Why revisions matter more than quantity

Most prototypes go through two or three revisions. Where you place those revisions changes total cost more than anything on this list.

• Same shop, small change: the programmer edits existing toolpaths. Rev B costs noticeably less than Rev A.
• New shop, same change: full programming and setup again.
• One piece per revision, many revisions: you pay setup every time.

If you know testing needs three pieces, order three. If Rev B is likely, keep it with the shop that made Rev A unless something went wrong.

How to compare prototype quotes

Two quotes for the same part can differ by a factor of two and both be fair. Before you compare totals, check each quote for:

1. Quantity and price breaks. Does it show 1, 5 and 10 pieces, so you can see the fixed cost?
2. Material and certs. Same grade, same temper, mill certs included or not.
3. Finishing. Included, excluded or quoted as a separate line.
4. Inspection. Visual only, selected dimensions or a full report.
5. Lead time basis. Counted from order, from drawing approval or from material arrival.
6. Shipping and Incoterm. Delivered to your door or ready at the shop.
7. Revision terms. Whether programming is charged again on Rev B.

Quick checklist before you send the RFQ

1. STEP file plus PDF drawing with the critical tolerances marked
2. General tolerance note for everything else
3. Material grade and whether certs are needed
4. Quantity per revision and the likely next quantity
5. Finish only where it is needed
6. Your real deadline, not an early buffer date

A clear RFQ gets tighter quotes because shops do not have to price in guesses. When you are ready, send the drawing and we match it with up to three 5-axis shops that take prototype work. The shops quote you directly, matching is free for buyers and you get a reply within 24 business hours. If you are unsure whether the part needs 5-axis at all, read when 5-axis beats 3-axis and 3D printing.
