New Slicer Enables Horizontal Overhangs Without Support
A new slicer called WaveOverhangs aims to enable 3D printing of horizontal overhangs up to 90 degrees without support. This software uses unique toolpathing techniques to create rings of material that adhere to previously laid down layers. Although it is still in the experimental phase, users are encouraged to explore its capabilities and share their results.
- ▪WaveOverhangs is a new slicer that allows for 90-degree overhangs in 3D printing.
- ▪The slicer uses innovative toolpathing to create rings of deposited material that adhere to each other.
- ▪Currently, there are no presets available, requiring users to experiment with settings.

New Slicer Enables Horizontal Overhangs Without Support 16 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.
