From Computer File to Real Product

Prototype making companies work as the connection between a computer design and a real object. They focus on fast, produzione di piccoli batch, letting you test and improve your product before making thousands of them. The process might seem complicated, but it usually follows simple steps for customers.

1.  First Meeting & Revisione del design

The process starts when you send your 3D computer design file. The company’s engineers check your design for possible problems with the manufacturing process. They might suggest small changes to make the part stronger, più economico, or easier to make. This feedback is very valuable and prevents failed parts.

2.  Price Quote & Choosing Materials

Based on the design review, the company gives you a detailed price quote. Modern prototype makers often have online systems that look at your file and give you a price in seconds. During this step, you will also pick your material. A good partner will have experts who can help you choose the best material for what you need, whether you want heat resistance, flessibilità, safety for medical use, or high strength.

3.  Making the Part

Once you approve the quote, your part goes into production. The company uses the chosen technology – like 3D printing or computer-controlled cutting – Per fare la tua parte. The file goes to the machine, and the automated process begins.

4.  Finishing Work

A raw part straight from the machine is rarely the final product. Finishing services are needed to get the look and feel you want. This can include removing support material from 3D prints, levigatura, blasting for a smooth finish, pittura, coating metal parts, or putting together multiple pieces.

5.  Controllo di qualità & Spedizione

Before the part leaves the building, it gets a quality check. Workers use tools like measuring devices and visual checks to make sure the part meets the size, precisione, and finish requirements. Una volta approvato, it gets carefully packaged and shipped to you.

Main Prototyping Services Explained

Modern prototype companies offer many different manufacturing technologies. Understanding the basics of each will help you pick the right process for your project’s needs regarding speed, costo, Proprietà materiali, e aspetto.

3D Stampa

3D printing builds parts layer by layer from a computer file. It’s known for speed and the ability to create very complex shapes that are impossible with traditional methods.

• Stereolitmicromografia (SLA)
• Meglio per: High-quality prototypes with fine details and very smooth surfaces, perfect for visual models and testing how parts fit together.
• Materiali comuni: Light-cured plastic resins (standard, difficile, flessibile, alta temperatura).
• Note importanti: Parts can be brittle and may need light curing after printing. Not ideal for strong working parts.
• Sintering laser selettivo (SLS)
• Meglio per: Forte, working prototypes with complex shapes that don’t need perfectly smooth surfaces.
• Materiali comuni: Nylon plastics, often mixed with glass or aluminum for extra strength.
• Note importanti: The surface has a slightly rough texture. Parts are strong and good for tough testing.
• Modellazione di deposizione fusa (FDM)
• Meglio per: Basso costo, early concept models and simple working parts. It’s the most common and accessible form of 3D printing.
• Materiali comuni: Plastics like PLA, Addominali, Petg, and engineering plastics like Ultem.
• Note importanti: Visible layer lines and lower detail compared to SLA or SLS. Strength depends heavily on print direction.
• Fusione multi -get (Mjf)
• Meglio per: Making strong, working nylon parts faster than SLS, making it excellent for short production runs and complex prototypes.
• Materiali comuni: Nylon plastics, TPU (una plastica flessibile).
• Note importanti: Gives more consistent surface finish and equal strength in all directions compared to FDM.

Computer-Controlled Cutting

This process starts with a solid block of material and removes material using cutting tools to make the final shape.

• MACCHING CNC (3-asse, 5-asse)
• Meglio per: High-precision working prototypes and final parts made from metal or hard plastics. It offers excellent strength and tight precision.
• Materiali comuni: Alluminio, Acciaio inossidabile, Ottone, Rame, Titanio, and plastics like ABS, Policarbonato, and Delrin.
• Note importanti: 5-axis machining allows for more complex shapes in one setup but costs more than standard 3-axis. Part complexity can greatly affect cost.

Molding Processes

These processes use a mold or tool to shape the material. While they cost more upfront for tooling, the cost per part becomes very low when making many parts.

• Stampaggio a iniezione
• Meglio per: Medium production runs (1,000-10,000+ parti) e produzione ad alto volume. It’s the standard for mass-produced plastic parts.
• Materiali comuni: A wide range of plastics (Addominali, Polipropilene, Policarbonato, Nylon, ecc.).
• Note importanti: The initial cost of the steel or aluminum mold is high. Not cost-effective for just a few prototypes.
• Casting a vuoto (Urethane Casting)
• Meglio per: Di alta qualità, piccoli lotti (in genere 10-50 unità) of plastic-like parts. It’s perfect for marketing samples, user testing, and first production runs.
• Materiali comuni: Special plastics that can copy the properties of production plastics (rigido, simile a una gomma, chiaro).
• Note importanti: A master pattern (often 3D printed) creates a silicone mold, which has a limited lifespan. It’s a great step between 3D printing and injection molding.

Sheet Metal Work

This involves cutting, flessione, and putting together sheets of metal to create cases, parentesi, and panels.

• Meglio per: Prototypes and production parts for frames, casi, e parti strutturali.
• Materiali comuni: Alluminio, Acciaio, Acciaio inossidabile.
• Note importanti: Processes include laser cutting, water cutting, flessione, e saldatura. Design must account for bend curves and material thickness.

A 5-Step Process for Choosing Partners

Choosing a partner is more than uploading a file and picking the lowest price. A poor choice can lead to delays, budget problems, and a part that doesn’t work. Use this five-step process to carefully evaluate and select the best prototype making company for your needs.

Fare un passo 1: Define What You Need

Before you start looking, you must know what you need. A clear definition of your requirements is the foundation for a successful project. Senza di essa, you cannot effectively compare quotes or vendors.

• Elenco di controllo:
• *Proprietà materiali:* What does your part need to do? Be strong, flessibile, resistente al calore, or see-through?
• *Required Precision:* How exact do the measurements need to be? Standard precision is often enough, but critical features may need tighter control.
• *Finitura superficiale desiderata:* Does the part need to look perfect for a trade show, or is a rougher, working finish acceptable?
• *Quantità:* Are you making one part for a fit check, O 50 for a test?
• *Deadline:* When do you absolutely need the parts in hand?

Fare un passo 2: Check Technical Skills

Not all prototype makers are the same. Their equipment, competenza, and quality systems directly affect the final product.

• Do their listed services and materials match your project needs?
• Ask for sample parts or examples of projects with similar complexity and materials. This gives you a real sense of their quality.
• Ask about their Quality Management System. Certifications like ISO 9001 show a commitment to standardized, repeatable processes and quality control.
• We once worked with a vendor who claimed advanced CNC capabilities but mainly sent complex jobs to other companies, leading to communication problems and big delays. Always ask if they do the main manufacturing process themselves or if they send the work to other companies. Both approaches can work, but honesty is key.

Fare un passo 3: Valutare la comunicazione

Good communication is as important as good manufacturing. A partner who doesn’t respond or is unclear can hurt your project timeline.

• How quickly and completely do they respond to your initial question or request for quote?
• Do they provide a dedicated project manager or single contact person for your project?
• If they have an online platform, is it easy to use? Does it provide clear design feedback?
• A good partner will point out potential design problems early, saving you from a failed part.

Fare un passo 4: Check Reviews and Examples

Don’t just take the company’s word for it. Do your own research by looking for independent feedback.

• Look for reviews on independent platforms like Google, Thomasnet, or industry forums. Pay attention to comments about quality, delivery time, and customer service.
• Look at their website’s case studies. Do they show projects with similar complexity or in the same industry as yours? This shows relevant experience. A company specializing in simple consumer electronics cases may not be the best fit for a complex aerospace part.

Fare un passo 5: Compare Quotes Carefully

The cheapest quote is not always the best quote. A quote contains lots of information; you need to analyze it carefully.

• Look beyond the price. Compare the stated delivery time, shipping costs, and payment terms.
• Read the notes. A good quote will include design feedback or assumptions made by the engineer. One vendor might quote a lower price but note that a critical feature is out of tolerance, while another quotes higher to ensure that feature is met.
• If prices are very different, ask why. One vendor may have quoted a stronger process or a higher-grade material. Understanding the difference is critical to making an informed choice.

Understanding Prototype Pricing

Prototype pricing can seem unclear, but it’s driven by logical factors. Understanding these factors helps you manage your budget and even improve your design to reduce costs.

• Costo materiale: This is a main factor. A part made from common ABS plastic will be much cheaper than the same part machined from aerospace-grade Titanium or printed with a medical-grade resin. The raw material cost varies dramatically.
• Machine Time: The longer a machine works on making your part, the more it costs. For CNC machining, complex surfaces and deep cuts increase machine time. Per la stampa 3D, part volume and height are the main factors.
• Lavoro & Impostare: This includes the time an engineer spends on design analysis, a technician spends programming the machine and setting up materials and tools, and any manual finishing work. Think of 5-axis machining like hiring a specialist doctor – the setup is more complex and the expertise costs more, but it’s necessary for complex work.
• Complessità & Precisione: Part complexity is a major cost factor. A simple block with a few holes is far cheaper than a part with curved surfaces and hundreds of features. Similarly, requiring extremely tight precision requires more precise machines, velocità di taglio più lente, and advanced quality inspection tools, all of which add cost.
• Quantità: Making more parts at once reduces cost per part. The setup cost is spread over the number of parts. For CNC machining, fabbricazione 10 parts is much cheaper per piece than making one. For processes like injection molding or vacuum casting, this effect is even stronger due to the upfront cost of the mold.
• Finishing Work: Every manual step adds cost. Levigatura, pittura, rivestimento, threading holes, and assembly are all extra services that come with labor costs.
