FDM Printing 101note
First layer is everything — bed must be level, clean, and at temp (PLA ~60°C, ASA ~100°C enclosed). Watch first layer go down before walking away.
📝
Filament Storagenote
PLA absorbs moisture slowly — sealed bag with desiccant. ASA less hygroscopic. Nylon and PC MUST be dried before printing. Filament dryer not optional for engineering materials.
📝
Z-Offset Calibrationnote
Paper sheet should drag slightly between nozzle and bed. Recalibrate when changing nozzles or after failed prints.
📝
Common Failuresnote
Warping (bed adhesion/draft), stringing (retraction or wet filament), layer shift (belt tension), spaghetti (detached mid-job).
NOTES
We do not stock ABS or PETG. PLA / PLA+ / ASA cover 90% of FDM work here. Infill: 15–20% gyroid for most parts. 3 walls + 15% infill is usually stronger than 1 wall + 50% infill.
