The use of dyes in MJF 3D printing introduces a new type of finishing that is particularly effective in improving the aesthetics of manufactured parts. By directly absorbing the colour into the material, dyes ensure a uniform and homogenous colouring on the surface of objects. This method aims to raise the aesthetic quality of printed parts, offering more uniform and professional results than traditional painting.

Benefits compared to painting

Dyeing offers several advantages over traditional paintings, primarily because they do not alter the dimensional tolerances of the treated objects. Since they do not require the application of additional layers of material, dyes allow for the maintenance of the original measurements' precision without adding unwanted weight or thickness. Additionally, the surface of the object remains intact, without alterations or roughness caused by additional layers of colour.



Compatibility with other treatments

Another point in favour of dyeing is its compatibility with subsequent treatments such as vapor smoothing. This offers greater flexibility in the final finishing of objects, allowing for smooth and uniform surfaces even after the dye has been applied.


Homogeneous colouring

Dyes offer greater colour uniformity than conventional paints. Thanks to their ability to penetrate evenly into the material, dyes guarantee homogenous colouring over the entire treated surface, avoiding unpleasant differences in tone or streaks that can occur with paints.

Weerg, a leader in digital manufacturing, is pleased to announce the introduction of a wide range of new colours for Multi Jet Fusion 3D printing projects. This innovation, based on dying instead of painting, offers a number of significant benefits for customers.

New dyeing

The new dyes represent a significant evolution in the field of customisation and finishing of 3D printed parts with MJF technology. This technological advancement offers a number of advantages over traditional painting, revolutionising the production process.

Unlike painting, the dying is absorbed directly into the material of the printed part, without adding extra layers of material. This innovative approach ensures that tolerances remain unchanged, however generously dimensioned components may deform due to the temperature used during treatment. Thanks to this feature, customers can count on reliable and consistent results, regardless of the complexity of the design.

But the advantages of dyeing do not stop there. The finish obtained with dyes is more homogenous and uniform than with painting, resulting in parts with a superior aesthetic appearance. This uniformity of colour and finish adds a touch of class and professionalism to projects, fully meeting customers' expectations and needs in the field of design as well.

Advantages of dyeing

  • The colouring does not change dimensional tolerances, as no extra layers of material are added.

  • The surface does not change.

  • Does not exclude the possibility of further treatments such as vapor smoothing.

  • Greater colour uniformity compared to painting.

Critical factors

  • Limited maximum dimensions.

  • UV resistance limited in time and dependent on colour.

  • Large components may deform due to the temperature used during treatment.

Colours available from Weerg

The new colours available represent a real revolution in the world of 3D printing, offering customers a wide range of options to express their creativity and customise their designs like never before.

In addition to the top black already in Weerg's catalogue, there are new colours: yellow, red, blue, green and orange. This selection of eye-catching colours allows customers to give free rein to their imagination and create unique pieces that stand out for their style and originality.

However, the customisation possibilities do not stop there. Weerg can supply any desired shade upon request, thus offering an even wider range of customisation possibilities. Whether it's delicate pastel colours, bold, vibrant shades or subtle, sophisticated nuances, customers can count on Weerg to turn their ideas into reality with amazing precision and impeccable quality.

With this wide range of colours and customisation options, customers can create unique and distinctive pieces that perfectly suit their needs and personal tastes. Whether artwork, prototypes or finished products, Weerg is ready to help customers bring their boldest and most creative visions to life.

The colouring process

In addition to the wide selection of colours available, it is important to emphasise the process used by Weerg to obtain the different colours. The dyeing process starts with a piece of high-quality white Nylon PA12, which serves as a neutral base for applying the colours. This approach guarantees a uniform and homogenous base on which the dyes are applied.

Nylon PA12 White is an extremely versatile and durable MJF material, ideal for 3D printing and subsequent colouring. Thanks to its excellent mechanical properties and resistance to chemicals, parts printed with this material offer reliable and durable performance in a wide range of applications.

Thanks to this combination of high-quality material and advanced colouring process, customers can count on Weerg to deliver first-class 3D printing results that stand out for their beauty and quality.
