3D Printing

Additive manufacturing in 3D printing

3D printing for rapid prototyping and small batches

Are you looking for a partner for the production of prototypes and small series using the 3D printing process? Our service offers precision and replicability for your desired components. The focus of additive manufacturing at Robtrix is on functional prototypes and small series with fast availability. We support you in rapid prototyping, rapid tooling and in the production of small series.

For functional prototypes and tools

Fused Deposition Modeling (FDM)

In this 3D printing process, a plastic wire, also known as filament, is melted in the hot end of the FDM printer and applied to the print bed in layers. Only materials that can be liquefied or deformed under heat can be used. The soft printing materials are applied layer by layer and harden again after cooling. Suitable materials for this purpose include thermoplastics such as ABS, PLA, PVA, HIPS, PET, nylon and numerous other filaments based on metals, stone and more.

Combination of materials and colors

Polyjet process (Multijet Modeling MJM)

In the Polyjet process, a print head applies very fine droplets of a photopolymer to a platform, where they are immediately cured using UV light.

Ultra-thin layers (up to 14 μm) can be processed using Polyjet. A very high level of detail with surfaces that are very close to injection molding are possible. During production, different materials can be used in the printing process and also mixed, which enables completely new material properties.
Polyjet printing is therefore a very versatile process that offers a wide range of applications in prototyping.

For components with complex geometries

Stereolithography (SLA)

A basin filled with liquid photopolymer resin (also called resin), serves as the basis of the SLA process. The photosensitive material is cured at the predefined locations using a UV laser. The platform is lowered as soon as a shift is finished and the process starts again.

Since the workpiece is in a bath of liquid during manufacturing, support structures become necessary. The supports enable the precise production of components with highly complex geometries. SLA printers are therefore even suitable for use in medical technology.

Powder based 3D printing

Selective Laser Sintering (SLS)

As a powder bed-based 3D printing process, selective laser sintering (SLS) is used in particular for the production of prototypes and finished components made of plastic and metal.

SLS 3D printers work similarly to SLA machines by creating parts with lasers. Instead of resin, however, the component layers in SLS printing are created by sintering powder layers that are applied layer by layer.

A wide range of materials can be processed in the SLS 3D printer with high accuracy, making them ideal for industries such as aerospace and automotive.
