Slicedog builds a physics-based finite element model directly from a part’s STL file and chosen print settings, simulating perimeters, infill, and top/bottom layers separately rather than treating the printed part as a homogeneous material, the assumption conventional CAD/FEA tools rely on. This lets engineers predict weak points, test how print orientation or infill density affects strength, and validate parts before committing to a print run, with results independently verified against physical load testing at a university. The software is slicer-independent, fitting into existing CAD-to-STL-to-slicer workflows (Cura, OrcaSlicer, Bambu Studio, PrusaSlicer) and is aimed at functional FFF applications such as production tooling, fixtures, machine components, spare parts, and engineering prototypes. It’s developed by Dolphin Printer s.r.o., a startup founded by Daniel Puchta.
