Experience 3D printing in 8 different processes
Would you like to learn the 8 most important 3D printing processes in the length of a coffee break? Then follow us for a brief overview.
1. Selective laser sintering
With selective laser sintering (also SLS printing), the starting material (PA plastic) is in powder form. The laser beam traces the structures specified in the 3D files into this powder. In doing so, he fuses the resulting component into an unbreakable model.

2. FDM process
In the Fused Deposition Modeling (=FDM) process, the starting material (ABS plastic) is melted in the extruder of the 3D printer and cured on the print bed in the specified structure. The starting material is in the form of rolls or sticks. Depending on the particular FDM printer, the print bed can be fixed or moveable.

3. Stereolithography
In stereolithography (also SLA printing), we apply a liquid photopolymer layer by layer to a moving printing plate, which is pulled down each time. The respective model is created piece by piece.

4. HP-MJF method
The HP MultiJet Fusion (=MJF) process is based on the different properties of two liquids. One of the liquids acts as a heat conductor, the other as a thermal inhibitor. While the thermal conductor binds the actual object, the restraining liquid confines it at its edges.

5. Metal pressure
In principle, metal printing works like SLS printing, i.e. by selectively melting individual areas using a laser beam. One also speaks of selective laser melting or SLM processes. In contrast to the SLS process, however, the powder is not sintered in SLM printing.

6. FDB printing
In the Furan Direct Binding (=FDB) process, the 3D printer applies sand (as particle material) to the construction surface in thin layers of 80–400 µm. A high-resolution print head now selectively prints and glues these layers according to the specifications of the CAD files. This step is repeated until the height of the desired object is reached.
7. Ceramic print
With ceramic printing, the objects are built up in layers using special ceramic granules (applied using a nozzle).
8. CJP Procedure
In the ColorJet Printing (=CJP) process, the printer builds up the 3D printed object layer by layer from powder (polymer gypsum). Multicolored prints are also possible.
