FOUR ENGINES,
ONE CLEAR SIGNAL
Every rule runs on your mesh with process-specific thresholds, then results are color-coded by severity and highlighted on your 3D model.
FDM / FFF
Overhangs, bridges, warping, elephant foot, stringing — tuned to your nozzle, layer height and material.
SLA / DLP
Resin traps, drain holes, suction cups, peel forces, thin pillars, UV shadowing.
SLS / MJF
Powder escape, part nesting, heat concentration, enclosed cavities, wall distortion.
Metal DMLS
Downward surfaces, residual stress, hot spots, lattice struts, support volume.
