Frequently asked questions

Why is silk PLA more brittle between layers?
The silk additive lowers layer adhesion slightly. Print 5–10 °C hotter than basic PLA and keep the part cooling fan at 80–100 % for the best gloss.
Does the spool fit a Bambu Lab AMS?
Our 1 kg plastic spool is 200 mm outer diameter and 65 mm wide with a 54 mm hub, inside the width and diameter Bambu Lab lists for the AMS. Check the feeder label for the selected material. Wood and composite grades use the external holder, as does TPU on the full-size AMS. TPU 72D can use AMS lite.
Do I need to dry it before printing?
Popping and stringing can have several causes. Check moisture and print conditions separately. The listed drying values are supplier suggestions, not verified endpoints; confirm the grade, spool and dryer limits before heating. See the drying guide for a controlled workflow.
