Recommended settings for the Creality Ender 3 V3 SE with a 0.4mm nozzle. Direct drive extruder with CR Touch auto levelling. Select your filament below.
The Bambu Lab A1 is a fast, reliable direct drive FDM printer that handles most filaments with minimal tuning. Its all-metal hotend reaches 300°C, supporting everything from PLA to basic Nylon. The direct drive extruder means short retraction distances (0.5-1.5mm) and excellent performance with flexible filaments like TPU.
Speed: The V3 SE handles 60-100mm/s comfortably. Start at 60mm/s and increase gradually. The direct drive extruder handles speed changes better than the V2's Bowden setup.
Direct drive advantage: Unlike the older V2, the V3 SE has direct drive which means better retraction, easier TPU printing, and fewer stringing issues. Retraction distance should be 0.8-1.5mm — much shorter than Bowden.
Retraction: Direct drive means very short retraction — typically 0.5-1.0mm. If you see stringing, increase by 0.2mm at a time. Don't go above 2mm or you risk heat creep and jams.
