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, fabricación de lotes pequeños, 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 & Revisión de diseño
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, más económico, 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, flexibilidad, 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 – Para hacer tu 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, lijado, blasting for a smooth finish, cuadro, coating metal parts, or putting together multiple pieces.
5. Cheque de calidad & Envío
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, precisión, and finish requirements. Una vez aprobado, 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, propiedades del material, y apariencia.
3D impresión
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.
- Estereolitmicromografía (SLA)
- Mejor para: High-quality prototypes with fine details and very smooth surfaces, perfect for visual models and testing how parts fit together.
- Materiales comunes: Light-cured plastic resins (estándar, difícil, flexible, a alta temperatura).
- Notas importantes: Parts can be brittle and may need light curing after printing. Not ideal for strong working parts.
- Sinterización láser selectiva (SLSS)
- Mejor para: Fuerte, working prototypes with complex shapes that don’t need perfectly smooth surfaces.
- Materiales comunes: Nylon plastics, often mixed with glass or aluminum for extra strength.
- Notas importantes: The surface has a slightly rough texture. Parts are strong and good for tough testing.
- Modelado de deposición fusionada (MDF)
- Mejor para: Bajo costo, early concept models and simple working parts. It’s the most common and accessible form of 3D printing.
- Materiales comunes: Plastics like PLA, Abdominales, Petg, and engineering plastics like Ultem.
- Notas importantes: Visible layer lines and lower detail compared to SLA or SLS. Strength depends heavily on print direction.
- Fusión de chorro múltiple (mjf)
- Mejor para: Making strong, working nylon parts faster than SLS, making it excellent for short production runs and complex prototypes.
- Materiales comunes: Nylon plastics, TPU (un plástico flexible).
- Notas importantes: 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.
- Mecanizado CNC (3-eje, 5-eje)
- Mejor para: High-precision working prototypes and final parts made from metal or hard plastics. It offers excellent strength and tight precision.
- Materiales comunes: Aluminio, Acero inoxidable, Latón, Cobre, Titanio, and plastics like ABS, Policarbonato, and Delrin.
- Notas importantes: 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.
- Moldura de inyección
- Mejor para: Medium production runs (1,000-10,000+ regiones) y producción de alto volumen. It’s the standard for mass-produced plastic parts.
- Materiales comunes: A wide range of plastics (Abdominales, Polipropileno, Policarbonato, Nylon, etc.).
- Notas importantes: The initial cost of the steel or aluminum mold is high. Not cost-effective for just a few prototypes.
- Colocación de aspiradoras (Urethane Casting)
- Mejor para: Alta calidad, lotes pequeños (típicamente 10-50 unidades) of plastic-like parts. It’s perfect for marketing samples, user testing, and first production runs.
- Materiales comunes: Special plastics that can copy the properties of production plastics (rígido, de goma, claro).
- Notas importantes: 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, flexión, and putting together sheets of metal to create cases, corchetes, and panels.
- Mejor para: Prototypes and production parts for frames, casos, y partes estructurales.
- Materiales comunes: Aluminio, Acero, Acero inoxidable.
- Notas importantes: Processes include laser cutting, water cutting, flexión, y soldadura. Design must account for bend curves and material thickness.

Mecanizado CNC | Medio | Alto | Excelente (Rieles & Plástica) | Excelente |
Impresión 3D SLA | Rápido | Medio | Limitado (Resinas) | Excelente |
SLS 3D Impresión | Rápido | Medio | Bien (Mainly Nylons) | Bien (Slightly Rough) |
Colocación de aspiradoras | Medio | Bajo (para 10-50 unidades) | Excelente (Simulated Plastics) | Very Good to Excellent |
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.
Paso 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. Sin él, you cannot effectively compare quotes or vendors.
- Lista de verificación:
- *Propiedades del material:* What does your part need to do? Be strong, flexible, a prueba de calor, 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.
- *Acabado superficial deseado:* Does the part need to look perfect for a trade show, or is a rougher, working finish acceptable?
- *Cantidad:* Are you making one part for a fit check, o 50 for a test?
- *Deadline:* When do you absolutely need the parts in hand?
Paso 2: Check Technical Skills
Not all prototype makers are the same. Their equipment, pericia, 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.
Paso 3: Evaluar la comunicación
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.
Paso 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.
Paso 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 de material: 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. Para impresión 3D, part volume and height are the main factors.
- Mano de obra & Configuración: 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.
- Complejidad & Precisión: 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, velocidades de corte más lentas, and advanced quality inspection tools, all of which add cost.
- Cantidad: Making more parts at once reduces cost per part. The setup cost is spread over the number of parts. For CNC machining, haciendo 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. Lijado, cuadro, revestimiento, threading holes, and assembly are all extra services that come with labor costs.
