What is
3D printing?

3D printing, or additive manufacturing, is a production method with which a physical part is manufactured based on a design created with a 3D software.

There are many technologies currently used for 3D printing, but we at Proto&GO! are specialised in printing by Multi Jet Fusion, the latest technology from HP.

This is the most advanced technology with an industrial orientation for the manufacturing of parts made of polyamide PA12, a rigid, strong and ductile material, and TPU M95A, a robust and flexible material. With this technology, functional technical components can be achieved.

Most advanced
Technology

From Prototypes
to industrial Series Production

Multijet technology has made the step from additive manufacturing of prototypes to the production of industrial end-use parts. This technology allows the manufacturing of serial parts in a very short time without the need for high investments in moulds or tools.

The Multijet Fusion
Technology

During the printing process, a movable print head applies a thermally conductive melting agent to a powder layer of polyamide with a thickness of a few micrometres. Immediately afterwards, a heat source with infrared light lamps is applied, heating the powder and leading it to melt.

100% functional
Parts

Thanks to this 3D printing technology, it is possible to produce parts that are functionally more resistant compared to other technologies, such as laser sintering, because you obtain 100% isotropic parts. This means that they offer the same resistance in each of the axes without losing their high precision.

material

PA12

Polyamide PA12 is one of the most practical technical plastics on the market. It is used in all major industries and in many demanding applications. PA12 is mechanically robust, heat-resistant and biocompatible. It also has a very high resolution and precision, which is why it is used not only for prototypes but also for small series production of functional parts.

TPU M95A

TPU M95A is a flexible material suitable for the production of parts using 3D printing. Designed for both prototyping and production, this thermoplastic polyurethane (TPU) is perfect for end-use parts due to its excellent durability and mechanical properties. Parts made from this material offer high wear resistance, rubber-like elasticity (Shore ~ 90A) and high breaking elongation.

advantages

material- rigid or flexible

In addition to the rigid and resistant PA12, it is now also possible to manufacture flexible parts in TPU with a Shore of 90A. This material is ideal for the manufacture of bellows, seals or any other component that requires a certain elasticity.

Isotropy

Compared to most other additive manufacturing technologies, parts printed with HP MultiJet Fusion are perfectly isotropic, i.e. the strength of a printed part is the same in any of its three axes, and therefore in any direction of stress.

Speed

The layers only take a few seconds to be printed due to the large number of printheads. The fusing process is also integrated into the printing process itself, so there are no additional non-productive operations. As a result, HP MultiJet Fusion machines are faster than any of the FDM or SLS 3D printing technologies.

Resolution

Due to the use of very small droplets, the HP Multi jet Fusion 3D Printer has a very high resolution, which is incomparable to any other technology. Furthermore, thanks to the fast process, smaller layer heights can be used, improving resolution, detail and surface quality even more.
