| # Defect → Parameter Map |
|
|
| | Symptom (observable) | Likely cause | Correction in OUR override vocabulary | |
| |---|---|---| |
| | Edges lift after recoat / during lasing (curling) | Lased-vs-bed ΔT too large; bed temp low; IR misreading | Raise bed/surface temp target (+1 °C steps); verify thermal readings before trusting more heat | |
| | Curled edge caught by recoater | Late-stage curling | Pause-level decision: reduce energy % locally is not possible — consider object exclusion before recoater jam | |
| | Grainy, fragile, crumbly parts | Under-sintering (energy below SSR mid) | Raise laserFillEnergyDensity / totalEnergyDensityPercent toward mid-SSR | |
| | Caked, hard-to-clean part cake; bonded surroundings | Over-energy or bed too hot | Lower energy density first; then bed temp −1 °C steps | |
| | Orange peel / poor top surface | Energy slightly low or powder aged (poor coalescence) | Small energy increase; check powder refresh history | |
| | Ripples/banding on verticals | Bed/chamber temperature fluctuation | Inspect temperature traces; stabilize before parameter moves | |
| | Streaks/gouges along recoat direction | Debris on recoater or dragged curl | Extra full recoat pass (dry) to clear; inspect frame images | |
| | Short feed / incomplete powder coverage | Dosing insufficient | Increase powder dose factor / staged passes | |
| | Warp discovered post-build (in-build invisible) | Cooldown too fast; crystallization gradients | Slower cooldown; keep bed heater on longer after finish | |
