Printing Notes

OzFDM PLA+ is a toughened PLA — it prints in the same window as standard PLA but is noticeably less brittle, so you can push layer heights without the part becoming fragile.

Bed adhesion needs no glue on a textured PEI sheet. On smooth PEI, a light wipe of IPA is usually all it takes.

The A1 Mini is open-frame with an 80 °C bed ceiling, which limits it to low-warp materials — this profile stays inside that envelope.

Its lightweight direct-drive toolhead handles short retractions well, so there is no need for the long retracts a Bowden machine wants.

Slicer: Bambu Studio / OrcaSlicer. Dry the filament at 40 – 45 °C / 4 – 6 h before a long print — every figure above assumes dry filament.

Troubleshooting

Stringing between parts — Drop the nozzle to 205 °C and confirm the filament is dry. PLA+ absorbs less moisture than PETG but a damp roll still strings.

Layer lines more visible than expected — Reduce layer height to 0.12 mm and slow outer walls to 40 mm/s. PLA+ holds detail well at low speeds.

Part warps off the bed on large footprints — Add a brim. PLA+ shrinks very little, so warping is almost always a first-layer adhesion problem rather than a material one.
