Product Manufacturing

Industrial product manufacturing is the technical process through which a validated design is turned into functional, reproducible physical units suitable for use or commercialization, applying manufacturing technologies, quality controls, and production engineering methodologies tailored to the product and the required volume. It spans everything from obtaining functional prototypes to manufacturing short or long production runs, including component optimization and the selection of industrial suppliers.

As an external technical partner, INFINITIA takes part in all these stages, providing manufacturing engineering capability, rapid prototyping, and industrialization support. The goal is to turn a design into a real product that meets the defined technical, functional, and economic requirements, reducing technical risk before committing resources to series production.

Turning to an external technical partner for industrial product manufacturing is necessary when the company does not have the technologies, processes, or production capacity in-house needed to bring its design to life and validate it in the stages prior to series production. Typical situations include developing a new product that requires rapid prototyping or pilot-run manufacturing, updating an existing design that needs validation before scaling up, or industrializing a product whose production requires identifying and coordinating specialized suppliers.

Outsourcing product manufacturing does not mean losing control of the project: an external technical partner such as INFINITIA works in an integrated way with the client development team, providing manufacturing capacity, engineering judgment, and supplier management, while the client retains intellectual property and technical direction of the project, with full visibility over every decision made during the process.

Going straight to series production without having validated the design through prototyping or pilot runs means risking that design errors (incorrect tolerances, unsuitable materials, assembly problems, or unforeseen functional behavior) are detected only once a significant investment has already been made in molds, tooling, and the production process. Correcting these errors at the series production stage costs far more than detecting and resolving them during prototyping or short-run manufacturing.

In addition, product failures that reach the market without sufficient technical validation generate warranty costs, claims, and reputational damage that in many cases far exceed the cost of carrying out a prior validation phase. Manufacturing prototypes and pilot runs with specialized technical support is, in this sense, an investment in reducing the technical and economic risk of the project.

Selecting the most suitable manufacturing technology depends on several technical factors: the geometry of the product and its dimensional complexity, the materials required based on the expected functional demands, the production volume needed, the available timelines, and the project budget. For functional prototypes requiring good mechanical properties, selective laser sintering (SLS) is usually a suitable option. For parts with high dimensional and surface finish requirements, stereolithography (SLA) or triple jetting (Polyjet) deliver better results. For conceptual prototypes with less complex geometry, fused deposition modeling (FDM) is the most cost-effective option.

This selection is made technically and objectively, assessing the characteristics of the product and the manufacturing objectives before recommending the most suitable technology. This independent technical criterion, unlinked from any preference for a specific technology, is one of the differentiating values of the work carried out by INFINITIA as an external technical partner.

A conventional production supplier carries out the manufacturing process according to the specifications provided by the client, but does not bring engineering judgment to the product design or to how well the specifications suit the manufacturing process. An external technical partner such as INFINITIA, by contrast, combines manufacturing capability with technical analysis of the design, materials evaluation, interpretation of prototype results, and specific improvement proposals that optimize both the product and the manufacturing process.

This difference is especially relevant during the prototyping and pilot-run stages, where the goal is not just to manufacture units but to obtain technical information that helps improve the design and reduce project risk. INFINITIA combines analytical rigor with practical industrial vision, an approach that differs from accredited laboratories or technology centers, which tend to focus on regulatory validation, and complements specialized manufacturers, who prioritize production efficiency.

Manufacturing functional prototypes using technologies such as SLS or FDM makes it possible to obtain parts with representative mechanical properties, which can then be subjected to testing that reproduces the expected conditions of use: static and dynamic loads, fatigue cycles, temperature variations, exposure to chemical agents, or specific environmental conditions. Validating product behavior under these conditions requires combining prototype manufacturing with the appropriate characterization and validation testing.

The specialized team integrates prototype manufacturing capability with functional validation testing, making it possible to obtain real technical evidence of product behavior before committing to series production. Bringing manufacturing and testing together under a single external technical partner simplifies project management and ensures consistency between the manufactured prototype and the testing carried out.

Manufacturing prototypes and short runs reduces the total cost of the project by making it possible to detect and correct design errors before they carry over into series production. The cost of correcting an error at the prototyping stage is significantly lower than doing so once an investment has already been made in molds, tooling, and final production processes. In addition, prior design validation makes it possible to optimize the selection of materials and manufacturing processes, reducing the unit cost of series production.

Industrialization support and the technical selection of suppliers also help reduce costs, by ensuring the selected manufacturers have the right capabilities to produce the product to the required quality, avoiding rework costs, batch rejections, and supply chain delays resulting from supplier selection made without technical criteria.

The cost of manufacturing prototypes or short runs depends on several factors: the geometric complexity of the product, the materials required, the manufacturing technology selected, the number of units, and the available timelines. For single-unit prototypes or very short runs using additive manufacturing, costs are significantly lower than those of conventional manufacturing processes that require tooling or molds. For short runs of between 10 and 500 units, the cost depends on the type of product and the manufacturing processes applied.

INFINITIA carries out a personalized technical assessment for each project before providing a cost estimate, evaluating the product requirements and the available technology options. To request an assessment, you can contact the INFINITIA team directly.

Manufacturing timelines for prototypes using additive manufacturing technologies (SLA, SLS, FDM, Polyjet) typically range from 1 to 2 weeks for single-unit prototypes or very short runs, depending on the complexity of the product and the finishes required. For short runs of between 10 and 500 units, timelines depend on the technology used and the volume, typically ranging from 2 to 4 weeks. In critical cases requiring an urgent response, INFINITIA can manage timelines of 1 to 2 weeks for high-priority prototypes.

Industrialization support and coordination with suppliers for long runs involves longer timelines, shaped by the production times of the selected manufacturers and by the validation and quality control stages included in the process. A detailed timeline plan is provided for every project before it begins.

This problem is common when manufacturing specifications do not adequately reflect the real conditions of use of the product. A conventional manufacturing supplier produces according to the specifications it is given; if those specifications do not account for all the relevant variables (combined loads, fatigue cycles, environmental conditions, accumulated tolerance variations in assembly), the product may meet the manufacturing acceptance criteria and still fail when subjected to real conditions of use.

Solving this type of problem requires reviewing the manufacturing specifications from a product engineering perspective, identifying the use variables not captured in the current specifications, and defining validation tests that reproduce real conditions. INFINITIA addresses this type of analysis as an external technical partner, combining a review of the manufacturing specifications with functional testing that makes it possible to identify the root cause of the failure and propose the necessary corrections.

The persistence of manufacturing problems after corrections have been introduced is usually a sign that the root cause of the problem has not been correctly identified. Corrections implemented without rigorous technical analysis tend to address the visible symptoms of the problem (an out-of-tolerance dimension, an incorrect surface finish, an assembly failure) without resolving the underlying cause, which may lie in the product design, the manufacturing process, the materials used, or the interaction between several of these factors.

This type of situation is addressed through systematic technical analysis that combines a review of the design, analysis of the manufacturing process, and characterization of the materials involved, with the aim of identifying the root cause of the problem and proposing effective corrections that eliminate the failure for good. This evidence-based approach to problem-solving is one of the differentiating values of the work carried out by INFINITIA as an external technical partner in product manufacturing.

The discrepancy between prototype behavior and that of the series-manufactured product is one of the most common problems in industrial product development, and it usually stems from differences between the prototype manufacturing process and the series production process. The additive manufacturing techniques used for prototyping can produce parts with mechanical properties, tolerances, or finishes different from those of the final production process and compared to processes such as series plastic injection molding. If these differences are not assessed and managed during the industrialization stage, the series-manufactured product may not replicate the behavior of the validated prototype.

Resolving this discrepancy requires active technical support during the industrialization stage, ensuring that the series production process is correctly defined and validated, and that the differences between the prototype and the series product have been assessed and are functionally acceptable. INFINITIA provides this technical support as part of its industrialization support service, ensuring consistency between the validated design and the product manufactured at scale.
