Laser melting (metal)

Selective Laser Melting is a layer-building 3D printing process in which metal powder is locally fused by the energy of a laser. The components are connected to a support structure which is firmly welded to the base plate. This ensures heat dissipation and fixation during production. The support structures are removed manually after 3D printing.

Selective laser sintering (plastic)

Selective Laser Sintering is an additive manufacturing principle in which thin layers of a powdered plastic are fused into a 3D object. Using a squeegee, a combination of several squeegees or a roller, a fine layer of powder is applied to the build platform and heated to just below the melting point. Using an infrared laser, the thermoplastic material is melted using predetermined coordinates.

Multi Jet Fusion

Multi Jet Fusion is a new 3D printing process in which plastic in powder form is made into innovative 3D objects at high speed. Unlike the established powder-based methods of selective laser melting and selective laser sintering, the individual layers of the material are not melted using laser beams. Instead, the powder is jetted with two different binding agents and melted by the thermal energy of several infrared lamps.

Stereolithography (plastic)

Stereolithography is a layer construction system in which a liquid plastic, such as epoxy resin, is cured locally in layers of 0.025 mm to 0.25 mm with UV light (UV laser). After a layer has been completely illuminated by the laser, the machine lowers the construction platform in the resin bath by exactly one layer of thickness. The surface is then again wetted with the liquid and the exposure process restarts. This process repeats until the object has been fully produced.

PolyJet/MultiJet Modeling

Of all 3D printing processes, PolyJet or MultiJet modeling most closely resembles traditional inkjet printing. A printhead moves across the build platform spraying fine droplets of a liquid polymer. The material is irradiated almost simultaneously with UV light and cured directly that way.

Ceramic 3D printing

The additive manufacturing process Lithography-based Ceramic Manufacturing (LCM) is used to produce ceramic components with the highest level of detail and a smooth surface. The basis for these high-performance technical objects is a ceramic powder monomer suspension. It is cured in layers in the first step under UV light and built that way to form a green body. The green body is then subjected to a thermal treatment at temperatures of up to 1600 °C, whereby the photopolymers which were used as binders are removed. In a final sintering process, the ceramic particles are compacted.

In the Binder-Jetting process, plastic powder is applied layer by layer and locally bonded with a liquid at the points where the component should be produced. The result of binder jetting is three-dimensional objects in almost any conceivable shape, without the use of support structures. In contrast to thermal processes such as selective laser sintering, the material is processed in a cold chemical process.
