The structural weakness of FDM 3D prints along the layer planes is a well-known problem. TenTech has now introduced a revised version of its G-code post-processing script that aims to solve this problem. The script specifically deforms the print paths by integrating sinusoidal wave patterns into infill and wall structures. The new version is open source and can be integrated into popular slicers such as PrusaSlicer, OrcaSlicer and Bambu Studio.
In conventional FDM printing, fractures tend to occur along the horizontal layers, as the adhesion between the layers is often lower than within a single layer. This weakness is reduced by the targeted introduction of wave-shaped deformations between the walls. The layers interlock organically, which can increase mechanical strength without having to resort to alternative materials such as resins or fiber reinforcements. Users have the option of individually adjusting the amplitude, frequency and direction of the waves, which allows fine tuning to different component geometries. The deformations can also smoothly transition between solid and non-solid areas to ensure stable transitions.
No firmware changes to the printer or special slicer versions are required to use the script. All you need is a Python environment and access to the generated G-code. The target group is particularly tech-savvy users who want to optimize the mechanical properties of their prints. The code is available on GitHub.
