CNC Prototyping Cases
Materials for CNC Prototyping
CNC prototyping is essentially using CNC machining to quickly make prototypes. This means any material that can be CNC machined can also be used for CNC prototyping. If you break it down to specific material grades, there are literally hundreds of them to choose from.
ABS
A general-purpose prototyping plastic that CNC machines cleanly for durable consumer-product housings
PC
A tough transparent plastic for CNC machined shatter-resistant prototype lenses or guards
PMMA
An optically clear plastic for CNC polishing into glossy display prototype parts
POM
A dimensionally stable slippery material ideal for CNC prototyping low-friction gears and bearings
PA6
A tough wear-resistant nylon for CNC prototyping durable mechanical sliding components
PA66
A higher-strength nylon variant for CNC machining heat-resistant functional test parts
PA6 GF30
A glass-filled nylon that stays rigid under load for CNC machined structural insulators
PP
A lightweight chemical-resistant plastic for CNC prototyping living hinges and tank linings
高密度ポリエチレン
An impact-resistant easy-flow plastic for rapid CNC cutting of budget-friendly large covers
PTFE
An ultra-low-friction fluoropolymer for CNC prototyping non-stick chemically inert seals
覗き見
A high-temperature engineering thermoplastic for CNC prototyping aerospace and medical load parts
Surface Finishing Options for CNC Machined Prototypes
Experience the convenience of First Mold's one-stop service with our full range of surface finishing options and competitive pricing
As-Machined (Raw)
部品の表面は、粗いものから滑らかで洗練されたものへと変化します。透明な素材の場合、研磨後の透明度は著しく向上します。.
Removes all visible machining marks to give the prototype a smooth, uniform, and non-reflective matte finish with a subtle frosted texture.
Adds a protective layer to aluminum prototypes, resulting in a premium, metallic-tinted appearance in custom colors without hiding the metal’s natural texture.
パウダーコーティング
Covers the raw material entirely with custom Pantone colors, making the prototype look exactly like a colorful, retail-ready mass-produced product in either a glossy or matte finish.
研磨
Smooths the surface completely, giving metal prototypes a highly reflective mirror-like shine, and turning clear plastics (like Acrylic) into a fully transparent, glass-like state.
Coats the prototype with a thin layer of metal (such as chrome or nickel), transforming its exterior into a shiny, ultra-smooth, and highly reflective premium metallic finish.

CNC Prototyping vs. Other Rapid Prototyping Methods
CNC prototypes are used for various types of validation on your products, such as material validation, functional validation, assembly validation, tolerance validation, appearance validation, and tactile validation.
| 特徴 | CNCプロトタイピング | 3Dプリンティング | 真空鋳造 | 高速射出成形 |
|---|---|---|---|---|
| 最適 | High-precision functional parts | Complex geometry, visual & functional prototypes | Small batches (10–50) of flexible/rubber parts | Bridge production (100+) with final materials |
| Accuracy | ±0.01–0.05mm (High) | SLA ±0.05mm, FDM ±0.15mm (Med) | ±0.15mm/100mm (Med) | ±0.05mm (High) |
| 素材 | Metals & Plastics | Resins, Plastics, Limited metal powders | PU simulating ABS/PC/Rubber/Silicone | プラスチック |
| 強さ | Excellent (Isotropic) | Isotropic (SLA/SLS) or Anisotropic (FDM) | ミディアム | Excellent (Isotropic) |
| リードタイム | 3–7 days | 1–3 days | 7–10 days | 10–15 days |
| Cost (1–10) | Medium–High | 低い | Medium (tooling amortized) | High (aluminum tool) |
| Min. Wall/Feature | ≥0.5mm (tool limited) | ≥0.8mm (SLA/SLS), ≥1.5mm (FDM) | ≥1.5mm recommended | ≥0.8mm (same as production) |
| Max Part Size | Very large (e.g., 1000mm) | Medium (~300mm) | Medium (~500mm) | Small–medium (mold frame limited) |
| Ideal Quantity | 1–50 pcs | 1～100個 | 10–50 pcs (mold life ~50) | 100–10,000 pcs |
| Design Constraints | Tool reach, internal sharp corners | Support structures, overhangs | Draft angles ≥1°, uniform walls | Draft ≥0.5°, avoid undercuts |
If you need high precision, a fine surface finish, and parts that are transparent or made of metal, CNC is your best choice.
If your design is complex, still being updated often, and you need to keep costs down, 3Dプリンティング is the way to go.
If you only need 10–50 plastic parts, want a rubber-like feel or clear material, and don’t want to pay for a mold, vacuum casting is the best option.
If your design is final and you need thousands of parts for market testing, rapid injection molding is the top choice.

FAQ for CNC Prototyping Services
What happens if my CNC prototypes are out of tolerance?
Can you recommend the best material for my CNC prototype?
Certainly. Whether you are aiming to make a plastic prototype or need to make a metal prototype, just tell us the intended use of the prototype, such as high temperature resistance, high toughness, transparent display, or food contact, and our engineers will recommend suitable materials (e.g., ABS, PC, POM, aluminum alloy 6061, 7075, etc.).
How do you prevent deformation in thin-walled parts?
Before quoting, we assess the machining risks of the thin-walled structure and provide professional advice. If our assessment shows that deformation will not occur, the parts you receive will be free from deformation. We control deformation by optimizing the jigs and fixtures plan, using small depth of cut with layered CNCプログラミング, removing material symmetrically, and adding process stiffeners.
Can you match custom Pantone colors for painted parts?
Do you charge set-up or programming fees for prototypes?
Our prototype quotations do not have a separate set-up fee. Programming costs are usually absorbed into the unit part rapid prototyping price. For very few complex orders or single-piece orders, a minimum charge may apply, but this will be clearly listed in the quotation with absolutely no hidden fees.
Can you transition from prototyping to small-batch production?
How long is the CNC prototype quotation valid?
Our quotation is valid for 30 days. Due to price fluctuations in raw materials such as aluminum alloys and plastics, the CNC加工費 may need to be reconfirmed after expiry. If raw material market prices experience extremely large fluctuations during a certain period, the validity period may be relatively shortened accordingly.
