Choosing the right material for your campionamento del prototipo is make-or-break for product development. Il materiale che scegli influisce sulla qualità dei test di funzionalità del tuo prototipo, mostra i dettagli del design, e si allinea con l'uso nel mondo reale. Sia che tu stia costruendo un 外壳 di plastica (alloggiamento) per un gadget o una parte metallica per un'auto, understanding your material options helps you avoid rework, save money, and create a prototype that truly represents your final product.
Sotto, we’ll break down the most common prototype sampling materials, their key features, ideal uses, and practical tips—with easy-to-read tables and real-world examples to guide your choice.
1. Plastic Materials for Prototype Sampling: Versatile and Cost-Effective
Plastics are the most popular choice for campionamento del prototipo because they’re lightweight, easy to shape, and mimic the properties of mass-produced plastic parts. From transparent lenses to durable gears, there’s a plastic for nearly every need. Let’s compare the top options:
| Materiale | Proprietà chiave | Ideal Prototype Uses | Surface Treatment Options | Fascia di costo (Per kg) |
| ABS | Good welding strength, matches injection molding plastic performance; available in standard and flame-retardant grades | General product housings (per esempio., custodie per telefoni, telecomandi), electronic device shells | Galvanotecnica (water/plating), vacuum evaporation plating, pittura | \(2.50 – \)4.00 |
| computer | Excellent strength, tenacità, and transparency; glass fiber-reinforced versions boost rigidity and heat resistance | Lens parts (per esempio., obiettivi della fotocamera, LED covers), high-strength structural components (per esempio., cornici per laptop) | Lucidatura, pittura, silk-screen printing | \(3.80 – \)5.50 |
| PMMA (Acrylic/Organic Glass) | High transparency (92% trasmissione della luce), easy to dye | Transparent parts (per esempio., coperture dello schermo, light fixtures) | Dyeing, galvanica, pittura, silk-screen printing | \(3.20 – \)4.80 |
| PP | Semi-transparent, elevata resistenza agli urti, flessibile | Impact-resistant products (per esempio., car cup holders, packaging boxes, children’s toy parts) | Surface grinding, stampa | \(2.20 – \)3.50 |
| PA66 + GF30 | Alta resistenza, special thermal stability, hydrolysis resistance | Mechanical part shields (per esempio., gear boxes, motor covers) requiring rigidity and dimension stability | Sabbiatura, pittura | \(5.00 – \)7.20 |
| POM | Excellent mechanical properties (alta resistenza, resistenza all'usura) due to regular molecular structure and crystallinity | High-strength moving parts (per esempio., ingranaggi, rotating shafts, parentesi) | Lucidatura, lubricant coating | \(4.50 – \)6.00 |
Why this matters: Per esempio, if you’re prototyping a wireless earbud case, ABS is a great fit—it’s cheap, easy to plate (for a shiny finish), and acts just like the plastic you’ll use in mass production. If your prototype needs to be transparent (like a smartwatch screen cover), PMMA O computer would work better—just note that PMMA is more brittle, so it’s not ideal for parts that get frequent impact.
2. Metal Materials for Prototype Sampling: Forza e durata
When your prototype needs to mimic metal parts (per esempio., in aerospace or automotive projects), metallo campionamento del prototipo materials are the way to go. They offer rigidity, resistenza al calore, and a premium feel that plastics can’t match. Here are the most widely used options:
2.1 Lega di alluminio: The Go-To for Lightweight Rigidity
Lega di alluminio is a favorite for campionamento del prototipo because it’s:
- Facile da lavorare (faster and cheaper than steel)
- Leggero (1/3 the weight of steel) but rigid
- Available in a wide range of anodizing colors (nero, argento, oro, ecc.)
Common uses: Componenti aerospaziali (per esempio., telai per droni), parti automobilistiche (per esempio., dashboard brackets), ed elettronica di consumo (per esempio., laptop bottom cases).
Data point: According to the Aluminum Association, aluminum alloy prototypes have a 30% faster machining time than steel prototypes—saving you 1-2 weeks on sample production.
2.2 Magnesium Alloy: Ultra-Light for 3C Products
Lega di magnesio is the lightest structural metal, making it perfect for campionamento del prototipo in consumer 3C products (computer, communications, elettronica di consumo). Its key benefits include:
- Elevato rapporto resistenza/peso (stronger than plastic, più leggero dell'alluminio)
- Good heat dissipation (ideal for parts near batteries or chips)
Critical note: Magnesium alloy is flammable during machining, so it requires strict environmental control (per esempio., low-temperature cutting fluids, well-ventilated workshops).
Esempio: Many smartphone manufacturers use magnesium alloy prototypes for phone middle frames—they reduce the device’s overall weight while keeping it sturdy.
2.3 Ottone: A Cost-Effective Stainless Steel Alternative
Ottone (an alloy of copper and zinc) is great for campionamento del prototipo when you need the look and feel of stainless steel but want to save on machining costs. Its advantages are:
- High wear resistance (lasts longer than plastic in moving parts)
- Easy to polish and plate—after treatment, its surface and texture are nearly identical to stainless steel
- Lower machining difficulty than stainless steel (stainless steel is hard and can damage tools)
Ideal uses: Prototype parts that need a metallic finish (per esempio., maniglie delle porte, watch casings) or require wear resistance (per esempio., piccoli ingranaggi).
3. Key Factors to Consider When Choosing Prototype Sampling Materials
Picking a material isn’t just about its properties—it also needs to align with your prototype’s goals, bilancio, e cronologia. Ecco i 3 most important factors to weigh:
3.1 Prototype Purpose: What Do You Need to Test?
- If testing appearance: Prioritize materials with good surface treatment options (per esempio., ABS for plating, PMMA for transparency). Per esempio, a prototype of a luxury speaker would use ABS (electroplated for a metallic shine) to show off the final look.
- If testing functionality: Choose materials that match the final product’s strength or flexibility. For a prototype of a folding chair hinge, POM (alta resistenza) O ottone (resistenza all'usura) would work—they mimic how the hinge will perform in real use.
- If testing heat resistance: Go for glass fiber-reinforced computer O lega di alluminio—these materials hold up in high-temperature environments (per esempio., a prototype for a coffee machine part).
3.2 Costo: Balance Performance and Budget
Materials vary widely in price—PP O ABS are budget-friendly (great for early-stage prototypes), Mentre PA66 + GF30 O lega di magnesio cost more (better for late-stage prototypes that need to match final product specs).
Tip: For initial design validation, use a cheaper material (per esempio., ABS) to test shape and fit. Once the design is locked in, switch to a material that matches mass production (per esempio., PA66 + GF30 for mechanical parts) for final testing.
3.3 Lavorabilità: Will It Slow Down Your Timeline?
Some materials are harder to shape than others. Per esempio:
- ABS E lega di alluminio are easy to machine—prototypes can be ready in 1-3 giorni.
- Acciaio inossidabile (often replaced by ottone per prototipi) is hard and may take 5-7 days to machine.
If you’re on a tight deadline, choose materials with high machinability to avoid delays.

Domande frequenti
- Can I use PMMA for prototype parts that need to be impact-resistant?
No—PMMA is highly transparent but brittle. It’s prone to cracking if dropped or hit, so it’s not suitable for impact-resistant parts. Scegliere computer (tough and transparent) O PP (flexible and impact-resistant) instead.
- Is magnesium alloy a good choice for low-budget prototype sampling?
Usually not. Magnesium alloy costs more than lega di alluminio and requires special machining (to prevent flammability), which adds to expenses. For budget-friendly metal prototypes, lega di alluminio is a better option.
- How do I know if a material matches my mass-produced product?
Prioritize materials with the same “base properties” as your final production material. Per esempio, if your final product uses flame-retardant ABS, use flame-retardant ABS for prototyping (not standard ABS). Ask your material supplier for a “property sheet” to compare—this ensures your prototype behaves like the final product.
