A recently published open source solution promises to significantly improve the mechanical strength of 3D-printed parts through an intelligent layer pattern. The technique was developed by Roman Tenger, who provides it as a script for PrusaSlicer and OrcaSlicer. The method uses a “brick structure” in which the first layer of a wall is adapted so that subsequent layers interlock. This principle increases stability without the need for special hardware.
The script, which was published under the GPL v3 license, relies on simple installation. Users only need to download the Python file and specify the file path in the slicer settings under “Post-Processing Scripts”. Currently, the target layer height has to be entered manually.
The approach of implementing the interlock structure in 3D print layers is not new. Back in November, a similar technique attracted attention, but was shelved due to potential patent issues. Tenger explains that he believes he is on safe legal ground in Europe, as although the technology has been patented in the USA, there are no corresponding patents for Europe.
Initial tests show that the technology is effective and enables significant improvements in the stability of printed parts. Especially for components that have to withstand high mechanical loads, the method could play an important role.
