OrcaSlicer Project
Download from the vendor

OrcaSlicer forked from PrusaSlicer and added what was missing: a series of built-in calibration tests — flow rate, pressure advance, temperature, maximum volumetric speed and interlayer adhesion — that run from inside the program and produce the right profile for your machine and material.
For anyone printing functional parts that saves hours of trial and error, particularly when working with engineering materials such as PETG, ABS or reinforced nylon. It supports a wide range of printers, including multi-tool and multi-colour machines.
