Tips and Tricks

Stringing

Some 3D prints sometimes show thin plastic threads at the point where the print head leaves the model to move to another position. These unwanted plastic strands are called "stringing".
This effect may be due to material or incorrect print settings.

Depending on the printer model, the material retraction can be used at the points where the print head moves between the positions. Here, the filament is slightly pulled back into the print head, so that it does not escape from the nozzle during the movement. Another way to reduce the thread pulling is to lower the temperature. The print material is thus not quite as fluid and draws less threads.

Deformation (warping)

The distortion at the corners is due to the shrinkage of the material during 3D printing, with the corners raised from the bottom plate. When plastics are printed, they initially expand due to the temperature. When cooling down, the print material contracts slightly again. If the plastic material contracts too much, it comes at the corners to the so-called "warping".

In order to minimize this effect, it must be ensured that the 3D printing adheres to the printing plate. In addition, it is recommended to use a heatable building board.
