New Slicer Enables Horizontal Overhangs Without Support
A new slicer called WaveOverhangs, based on OrcaSlicer, aims to enable 3D printing of horizontal overhangs up to 90 degrees using innovative toolpathing inspired by wave propagation. Instead of relying on support structures, it deposits material in interlocking rings that adhere to previously printed sections of the same layer. The technology is experimental, requiring manual tuning of settings and extensive trial and error. Success depends on precise calibration, with no presets currently available.

New Slicer Enables Horizontal Overhangs Without Support 6 Comments by: Zoe Skyforest April 28, 2026 Title: Copy Short Link: Copy There’s a rule of thumb when it comes to FDM printing that overhangs are really only possible to an angle of around 45 degrees or so. If you try to squirt out plastic with nothing supporting it, it just goes everywhere. However, a new slicer hopes to enable printing up to 90-degree overhangs with some creative techniques. The software that enables this is called WaveOverhangs, and currently exists as a fork of OrcaSlicer. The idea is straightforward enough — using unique toolpathing to create rings of deposited material that fasten to those laid down before them in the same layer.
