Dear Simpliofy3D Team,
Pls. evaluate integrating arc mode slicing script for printing overhangs w/o supports.

Arc mode does slice overhang base layers in free space as arcs. Priting the layer in free scpace in a stacked overlapping fashion exploits driving the stepper in arc mode and eliminate the excess heat sagging from decelerating the extruder at sharp corners.
The arc slicing can be integrated from existing Python script.
It does a trade of between faster xy-line-print mode and optimized heat transfer. It avoids using angled slicing and a 4th axis print head.
It achieves the same amazing results with minimal software effort. It is also suitable to avoid hard to remove internal supports.
This can be implemented in several ways - from prinitng the part entirely in arc mode to doing specific sections or specific overhang base layers.
In my understanding full early arc mode support would greatly improve the incentive for a paid quality slicer upgrade for many users. It is highly attractive option for professionals seeking to minimize pre-processing and post-processing in a very reliable way. It also avoids the implications of a heavier dual extruder for washable support material, allowing to achieve similar results on a standard printer with less acceleration / deceleration of mass in the printer frame.
Best Regards
