Prototyping and prototype manufacturing

Industrial prototyping is the process of turning a concept or technical design into a physical, functional item that makes it possible to validate solutions before series production. It is used to detect design errors in the early stages, reduce technical uncertainty, and make decisions based on experimental data, avoiding cost overruns and failed industrialization.At INFINITIA, prototyping is designed as a strategic tool that connects design, material selection, manufacturing processes, and technical validation within an overall industrial product development process.

INFINITIA manufactures four main types of prototypes depending on the maturity level of the project:

This diversity makes it possible to tailor the type of prototype to the exact stage of the project and its technical objectives. If you are not sure which one you need, the usual starting point is an ideation and concept definition phase that helps narrow down the approach before starting any manufacturing.

INFINITIA has proven prototyping experience in sectors such as automotive, aerospace and energy, manufacturing and capital equipment, medical devices, food and packaging, as well as R&D projects and industrial startups.

In each setting, prototyping is adapted to the regulatory and technical requirements specific to the sector. For example, in automotive we validate mechanical behavior and dimensional tolerances under demanding conditions; in medical devices, the process is geared toward functional safety and meeting requirements prior to certification. You can check practical examples of our projects in the completed product development projects section.

These are three different tools within the prototyping process, with complementary objectives:

• The Proof of Concept (PoC) verifies whether an idea is technically viable before investing in development. For example, checking whether a closing mechanism withstands the expected use cycles before designing the final part.
• The Minimum Viable Product (MVP) is the smallest version of the product that provides real learning from users or clients with minimum effort. For example, a functional version of a device without its final housing that makes it possible to validate user interaction. You can learn more about this concept in our article on what an MVP is and how to apply it.
• The Minimum Lovable Product (MLP) goes a step further: it includes the attributes that create a positive user experience, not just the minimum functional ones. For example, a polished surface finish or well-developed ergonomics that already appear in the first version presentable to the client.

At INFINITIA, we help decide which approach is most suitable based on the maturity of the project and the resources available.

INFINITIA uses various technologies depending on the type of prototype and the requirements of the project. The most commonly used include additive manufacturing (3D printing), CNC milling, laser cutting, and precision machining processes. Choosing the most suitable technology in each case is part of the technology selection and testing process we apply before manufacturing, avoiding decisions that later have a negative impact on design or cost. If you would like to learn more about one of the most in-demand technologies, you can read our article on 3D printing for agile prototype manufacturing.

Combining these technologies makes it possible to manufacture prototypes with a high level of geometric detail, representative materials, and shorter lead times. Rapid prototyping stands out for its ability to bring a design to life on the same day, at a fraction of the cost of traditional processes.

Prototyping is one stage within a broader development workflow. At INFINITIA, it usually builds on prior work in conceptual design, 3D modeling, and part optimization, ensuring the prototype is consistent with the functionality criteria, tolerances, and manufacturing processes planned for the final product.This integration makes a particular difference in parts with complex geometries or in projects where the material behaves differently depending on the process: a part designed without considering that it will be machined may require operations that are impossible or very costly, while one designed from the outset for additive manufacturing can be greatly simplified. Using 3D scanning and part digitization adds an extra layer of precision when working from existing physical parts or reverse engineering references.

Yes. Having INFINITIA as an external technical partner makes it possible to maintain project consistency beyond prototyping, also covering the validation of industrial suppliers, monitoring during production, and the design of tooling and manufacturing support elements.This end-to-end support model (from idea to series production) reduces the risks associated with changing points of contact between phases and ensures that the decisions made during prototyping are correctly carried through to production.

Yes. At INFINITIA, prototyping is not limited to manufacturing a part: having a specialized external technical team makes it possible to assess the prototype through functional testing tailored to the project requirements, using objective, independent criteria. Depending on the case, this can include mechanical, thermal, or chemical behavior analysis, durability testing such as accelerated aging tests, tolerance verification, or checking compliance with regulatory requirements under standards such as ISO, UNE, or ASTM depending on the sector and type of product.

This testing capability is what sets the INFINITIA service apart from a simple manufacturing provider: the results become actionable technical information for improving the design before it reaches production.

Yes, and it is one of the profiles we work with most often. For startups and industrial entrepreneurs, having an external technical partner like INFINITIA makes it possible to go from idea to validated object without committing significant resources or building an in-house engineering team. We provide support from the technical definition of the product through to obtaining a functional prototype that can be tested with real users or presented to investors, following the steps detailed in our article on how to develop innovative products.

This multidisciplinary support (combining engineering, materials, and processes within a single team) significantly reduces time and risk in the early stages of the project.

You can contact INFINITIA through the form on this page or through our contact page. Our team responds promptly and, depending on the urgency and budget of the project, we guide you on the most suitable type of prototype and the steps to follow from the very first moment.

The cost of an industrial prototype varies depending on the geometric complexity of the part, the materials required, the manufacturing technology used, and the level of validation needed. As a general guide, a conceptual prototype made using 3D printing can cost just a few hundred euros, while a functional pre-series prototype with associated technical testing can range into several thousand, depending on the sector and applicable regulatory requirements.One key point: the cost of prototyping should always be weighed against the cost of not prototyping. Failures detected during the design stage are exponentially cheaper to fix than those detected in series production, where they involve rework, defective tooling, or product recalls. If you would like an estimate tailored to your project, you can request a no-obligation quote through the contact form: typical timelines range from 1 to 4 weeks, and for urgent cases we offer an expedited quotation option with a response time of 24 to 72 hours.

INFINITIA is not a typical prototype manufacturing workshop: it is an external technical partner with its own capabilities in materials, testing, and product development. This means the prototype is not delivered as a standalone part, but within a technical process that includes requirements definition, design iteration, validation through testing, and preparation for industrialization.In addition, our multidisciplinary team brings together profiles in mechanical engineering, materials science, and manufacturing processes, making it possible to tackle complex projects in demanding sectors such as automotive, medtech, or aerospace.
