3iD | 3D idea printing

3d prototype

Are you developing a new product and want to test it quickly and reliably? With 3D prototyping, 3iD turns your digital idea into a tangible model within just a few days. This way, you can immediately see, feel, and test whether your concept works – even before investing in expensive production methods.

At 3iD, we support companies, designers, and engineers across Belgium in creating their 3D prototypes. With our industrial 3D printers and extensive material selection, we deliver realistic models suitable for both visual presentation and functional testing.

What is 3D prototyping? 

This is the process in which a digital design (CAD file) is transformed into a physical, tangible 3D prototype.

Launching a new product is always an investment. The earlier in the process errors are discovered, the more time and costs you save. 3D printing a prototype plays a key role in this.

Printing a prototype in 3D allows you to evaluate the look & feel of a product and thoroughly test its functionality. Concretely, 3D printing a prototype means you can:

  • Immediately see and feel whether your design is correct.
  • Test the functionality and fit of components.
  • Avoid costly modifications at a later stage.
  • Convince investors, partners, or customers with a tangible model.

Technologies for 3D prototyping

At 3iD, we use various industrial techniques to create your 3D prototype. Depending on the application, we recommend the right technology:

  • MJF (Multi Jet Fusion) – ideal for strong, functional parts that need mechanical testing. Lower cost per piece – the larger the batch, the more cost-effective it becomes.
  • SLS (Selective Laser Sintering) – suitable for complex geometries, internal structures, and lightweight yet durable parts.
  • SLA (Stereolithography) – delivers prototypes with exceptional detail and a smooth surface, ideal for design and medical applications.

Materials for 3D prototyping

A prototype must match the way you intend to use it. That’s why we offer a wide selection of materials:

  • PA12 – a versatile and strong polyamide ideal for prototyping, functional parts, and small to medium series. This material is printed with MJF or SLS and is available in gray and black as standard, with other colors on request.
  • PA11 – similar to PA12, but with more elasticity. Also printed with MJF, available in gray and black, with other colors on request. Perfect for prototypes requiring extra flexibility.
  • TPU – a flexible material perfectly suited for parts that need to be bendable or elastic. TPU is printed with MJF and is available in gray and black.
  • SLA resins – ideal for prototypes requiring a smooth surface and high precision. These resins are particularly suited for visual models and medical applications, produced with SLA technology.

Frequently asked questions about 3D prototyping

How quickly can I receive my prototype? 

The lead time depends on the chosen technology, the size, and the complexity of your design. In general, you can expect a turnaround of 2 to 7 working days. For projects with a tight deadline, we are happy to explore expedited delivery options with you.

Which material is best suited for my prototype?

This depends entirely on your application. For visual models where fine details and a smooth finish are crucial, SLA resins are ideal. Does the prototype need to be functionally tested for strength and durability? Then materials like PA12 and PA11 (via SLS and MJF) or the flexible TPU (via MJF) are excellent choices.

How do you guarantee consistency between the parts in a series?

Our industrial machines are calibrated and operate within strict process parameters. In addition, we always carry out thorough quality checks after printing. This ensures that all parts are identical and meet the requirements.

Which materials can be used for series 3D printing?

We offer a wide range of materials suitable for series production, including PA12 for strong and durable parts, TPU for flexible applications, and various SLA resins and SLS powders for high precision and special properties. 

What is the difference between a visual and a functional prototype?

A visual prototype, often made with SLA, focuses on appearance, precision, and surface quality and is perfect for visual evaluations and presentations.

A functional prototype, usually printed with MJF or SLS, is mechanically much stronger and more robust. This allows it to be intensively tested for fit, strength, and ergonomics under realistic conditions.

Can I have a transparent prototype made?

Yes, absolutely. One of the unique advantages of our SLA technology is the ability to print fully transparent parts. This is ideal for visual models or prototypes where the internal mechanism must remain visible.

Can I have multiple versions of my prototype printed?

Definitely, this is one of the core advantages of 3D prototyping. Since we work with digital files, you can iterate quickly and cost-effectively. A design adjustment can be applied directly for a new version. This way, you can easily test different variants and perfect your product.

Are my designs safe with 3iD?

Yes, the security and confidentiality of your intellectual property are of the utmost importance to us. All supplied CAD files are treated strictly confidentially and used solely for the production of your parts.
