![]() Unfortunately, after a few tests, it was clear that a simple modification of the existing implementation wasn’t compatible with FDM 3D printers. We first implemented these supports for SLA slicing in PrusaSlicer 2.0 (2019) and received a lot of feedback ever since to bring them to FDM slicing as well. Gradually expanding branches of supports are generated where needed and contact areas with the model are limited to a necessary minimum. We improved some of these downsides by introducing the “Snug” supports in PrusaSlicer 2.4, but they are still only an upgraded version of the old approach.Īn alternative approach, which was pioneered by various 3D modeling software and slicers is “Tree supports” – support structures designed to save material and printing time as much as possible. Especially when the settings were not tuned correctly. The supports often consumed quite a lot of filament, took a long time to print, ended up in spaces where they are difficult to remove from, and left visible marks on the model when removed. Although this method delivered decent results in many situations, it had its limitations. Until now, PrusaSlicer’s used a 2D grid-based approach to generate supports.
