5 Steps for Manufacturing Prototypes

Everything you tell us will be confidential. We understand the importance of secrecy in obtaining patents and distinguishing yourself in the market.

Request NDA

We will study your idea to define the important requirements. This will allow us to design products that align with your concept

Within 72 hours, you will have a firm quote. With whatever amount we indicate, we assume responsibility for meeting 100% of your prototype’s working requirements..

After initiating the manufacturing process for your working prototype, you will receive a timeline and work schedule. Each week, you will review the product development status.

The requirements list will now become a “checklist.” Together, we’ll check that 100% of the functions have been successfully delivered. We are committed to doing so as efficiently as possible.

Industrial Design Fabricación de Prototipos

Creating an invention with high chances of success involves overcoming challenges associated with industrial design, strategies for patenting inventions, and manufacturing prototypes that resemble the final product.

We manufacture more than 50 prototypes a year; here are some examples.

Pasos para desarrollar un Prototipo

If it's your first time developing an innovative product, you need information and good company.


To create an invention and make money, you need information. We have prepared a practical guide for you:Guide for Inventors


Everything you save in creating an invention and prototypes are manufactured, jeopardizes the future of your project. Prototype Design


90% of inventors make mistakes when patenting inventions. They choose the worst methods or the worst time to patent.. Patents type

Using as a benchmark the working requirements list shared during the retaining process, we will check each and every detail.

Información sobre Prototipos & Patentes

The cost of manufacturing a prototype can range between $10,000 and $50,000. 

The price difference of a prototype is conditioned by the level of uncertainty and the need for research in the prototyping process.

It is more resource-intensive to research the best way to manufacture a prototype than the actual manufacturing itself.

It is difficult to anticipate a price without knowing the scope of your invention, but we guarantee a fixed price within 72 hours. We have manufactured prototypes ranging from €1,000 to €70,000.

The price of the prototype is not similar to the price of the final product. For example, the manufacturing of the prototype of the first electric vehicle cost millions of dollars. In contrast, the final product is priced at $30,000 in the market.

It is important for you to know that the price of the prototype is not similar to the price of the final product, but they have a very close relationship.

The price of a final product is conditioned by how effective the product developers are during the prototyping stage.

The simple and cheap products in the market usually have countless hours of research and significant investments behind them to achieve competitive prototypes that lay the foundation for market competition.

For example, manufacturing the first prototype of Gillette razors in 1901 took many months and hundreds of thousands of dollars. In contrast, the final product, after decades, remains a leader in excellence and quality, with competitive prices that customers are willing to pay.

The process of manufacturing a prototype can take about 90 days.

The timeline for manufacturing a prototype can be affected by the level of uncertainty associated with the invention.

To quickly manufacture a prototype, it is most advisable to develop a basic engineering project.

To manufacture a quality prototype, it is important to isolate the research cycle from the prototype manufacturing. Facing the prototype creation process in two stages results in both cost savings in the prototype price and reduced time to manufacture a prototype.

Although it is an iterative process, it usually takes about 90 days to create a functional prototype. According to our prototyping method, you will be part of the process and will be informed of the progress every week.

The pre-series of a prototype is a handcrafted replica of the validated functional prototype. The pre-series of a prototype is not manufactured using industrial methods; instead, the prototype is reproduced following the same steps and using the same tools used to manufacture prototypes.

The price of the pre-series is entirely related to the characteristics of the functional prototype. 

The pre-series of prototypes are manufactured using non-industrial means. For this reason, the price of the pre-series should not be taken as a reference or compared with the prices of the final product.

The unit price in the pre-series is usually between 5% and 10% of the prototype's price.

The importance of manufacturing a prototype of an invention can be summarized in its three main objectives.

Objectives of manufacturing prototypes of inventions:

  1. Learn about the use cases. How the invention will be used. 
  2. Demonstrate the technical feasibility of the invention.
  3. Minimize the investment to industrialize the invention.

The process of design of an invention es grounds. Understands the testing cycle where the best solutions are chosen. Moving on to manufacture an invention Before the necessary testing cycle or the engineering project, It can undermine the resources of the inventor.. If you have an idea and want to know the step-by-step process to launch an invention into the market¡Podemos ayudarte!

El prototype es la primera unidad de un producto. El prototipo de un invento se consigue mediante un proceso iterativo cuyo objetivo es conseguir un diseño industrial y producto físico que demuestre la viabilidad técnica del invento.  

Before patenting an idea it is essential to have completed the process of industrial design. You should study the background of the invention, define theinnovation assertions para elegir el type of patent that best fits with yoursinvention

Prior to investing money in protecting your idea, you must demonstrate that it’s technically feasible. The best way to do this is with a working prototype. If you already have the patent for it, don’t worry, we can help you.

There is no relationship between theprototype price and themanufacturing cost of a product. The prototype is the unit that bears the full load of engineering and innovation. They are sacred and incomparable services and moments.

There are three methods to protect an invention (types of patents) : The Industrial Design/Design Patent, Utility Model, Invention Patent. It's important that you know their differences before choosing a method to protect an invention. 

Se considera MVP cualquier acción o experimento que permita a los inventores o emprendedores obtener un aprendizaje. 

El MVP no tiene que ser un producto físico. El MVP puede ser por ejemplo, un catálogo comercial de un producto que no exista, con el que se pueda obtener feedback de los futuros clientes. 

El error más común con el MVP es no simular escenarios reales. El MVP solo funciona cuando el cliente que interactúa con el él, siente que está ante una posibilidad de compra real. Solo así se obtiene información efectiva y fiable. 

Por el contrario, el prototipo es una etapa en la que se puede demostrar la viabilidad técnica de un invento. El prototipo es útil a nivel comercial, porque da indicios sobre la experiencia de uso por parte de los clientes. En el caso del your working prototype, busca sobre todo demostrar que el invento es viable a nivel técnico y que puede fabricarse. 

La principal diferencia entre un MVP y un prototipo, es que el MVP no tiene que ser un producto, es más bien una simulación de producto, útil para aprender sobre cómo los usuarios utilizarían un producto o si les interesa o no. El prototipo si es un producto, más que aprender si los usuarios lo utilizarían o no, persigue como objetivo, aprender sobre cómo será utilizado y que aspectos hay que mejorar antes de sacar el producto al mercado. 

El diseño industrial del producto, es la definición mecánica de partes y piezas que conformarán el your working prototype

El diseño industrial permite simular y evaluar el funcionamiento del futuro prototipo, en u entorno digital. 

Es más barato experimentar sobre el diseño industrial del invento, que en el proceso de fabricación del prototipo

El ciclo del diseño industrial de un producto, exige una investigación de materiales. Para determinar los materiales de un prototipo, será necesario comprender la finalidad de uso del producto, requisitos funcionales estéticos, de peso y resistencia mecánica necesaria. 

El diseño industrial se centra en la especificación mecánica y detalles de funcionamiento del producto. Por el contrario, el diseño gráfico no es más que la creación de una idea en formato realista y tridimensional. El diseño 3D de un invento no significa que el invento sea viable. Para demostrar la viabilidad de un invento, hay que fabricar un prototipo funcional


Los inventos se protegen a través de patentes, modelos de utilidad o registros de diseños industriales.

Las patentes y el registros de diseño industrial, son los métodos más recomendables para proteger un invento

El Utility Model, no existe en muchos países. El Modelo de Utilidad es un método de protección de inventos, débil y poco riguroso, aunque muy barato

Inventor, this letter is for you:

If someone has ever looked at you with a “funny” face or if you’ve felt like you don’t fit in in your professional and/or family environment, you’ve come to the right place! We have been working for over a decade with inventors who, like you, were born to create solutions to problems that any other person would overlook.

We are aware of the time and effort you’ve devoted to defining or patenting the idea, as well as the level of “disinformation” that may plague you when you decide to demonstrate its technical feasibility. If we’re in contact with one another, it’s because you’ve already discovered two things: the industry is not the optimal partner to design and manufacture your first prototype, and patent companies cannot lend you a hand at this stage.

Although it may sound right to define us as the “Macrocompany” of prototypes in Europe, the truth is that Let’s Prototype is an MSME with just 10 engineers in various specialized areas, joined by a common passion to face challenges head-on, regardless of the industry or complexity.
