Slicer & toolpaths
The slicer converts a 3D model into movements, extrusion and machine-specific instructions.
LEARN / FUNDAMENTALS
Understand your printer, not just its Print button.
Learn what the slicer is doing and why key settings affect detail, speed and part strength.
The six concepts to learn first
Layer height & line width
Smaller layers may improve surface detail while increasing print time. Line width affects geometry and extrusion.
Walls & infill
Part strength depends on material, wall count, layer bonding and orientation—not just infill percentage.
Temperature & cooling
Material flow, surface finish, bridges and bonding depend on heating and cooling choices.
Speed, acceleration & flow
Actual printing speed is constrained by motion limits and the hotend’s material throughput.
Supports & orientation
Orientation affects surface quality, mechanical strength, printing time and support removal.
Model-specific advice should always include the printer, slicer and version it was tested with. We keep outdated hardware tutorials out of this learning path.
