Engineering Technicians Strive to fully utilize the extreme performance of equipment and materials, providing stable and reliable print quality. ## Self-Use Design Manual 1 Maximize compatibility with all Bambu Lab FDM models, selecting reasonable splitting methods. 2 Set safe wall thickness for the top and bottom surfaces of the model, with a conventional wall thickness of not less than 10 times the layer height. 3 Thin wall thickness is an integer multiple of the line width, with minimum wall and perimeter thickness not less than 5 times the line width. 4 Use standardized installation methods, prioritizing snap-fits or standard bolt mounting positions, and non-standard threads for special conditions. 5 Reserve assembly clearance according to filament characteristics. For sliding fits, PLA: 0.15-0.2mm, PETG: 0.20-0.25mm. For tight fits, PLA: 0.05-0.10mm, PETG: 0.10-0.15mm. 6 Control fine features within the printable range, with minimum line width not less than 0.43mm. 7 In the XY plane, use fillets for corner processing and continuous lines for exterior surfaces to reduce start-stop segments and avoid exterior wall defects. 8 Add chamfers to bottom edges to prevent warping and improve bottom forming quality. 9 Avoid overhangs below 30°, with unsupported overhangs ≥45°. 10 Reasonably set supports and bridges to ensure print success rate and reduce post-processing workload. Short bridges not exceeding 40mm; if exceeding this range, configure easily removable supports.
