TenTech has developed a new script, Brick Layering, for 3D printing to improve the layer adhesion of vertical walls. The method is based on a modified layer structure that resembles a brick pattern. This could increase the adhesive strength between the individual layers. The script is currently optimized for PrusaSlicer and is available for download on GitHub.
Most 3D printers work with a classic wall structure in which several vertical walls lie next to each other without being connected. This often leads to the walls separating from each other under lateral pressure. The new script changes this structure: instead of parallel walls, staggered connections are created, similar to brickwork.
To achieve this, two consecutive layers are connected in a staggered zigzag pattern. The outer walls remain unchanged to ensure a clean surface quality. The developer recommends at least five walls to fully utilize the effect, but the script works with any number of walls.
As this is an experimental solution, there are not yet any reliable tests on the stability of the prints. However, TenTech expects better adhesion between the walls, increased shear stress resistance and generally improved mechanical stability. This process could be of particular benefit for models that are exposed to high lateral forces.
However, there are still some limitations. The script currently only works with a 0.4 mm nozzle and a layer height of 0.2 mm. In addition, errors can still occur with more complex geometries. Further development is planned.
To use the script in PrusaSlicer, Python must be installed. After downloading the script from GitHub, the path to Python is stored in the output options of the slicer, followed by the script path. After slicing, the file is automatically adjusted. The resulting model can be loaded back into the slicer for checking.
