Frequently asked questions
Is expensive PLA really better?
Premium brands mainly buy you consistency: tighter diameter tolerance, fewer batch variations and better-tuned profiles. For prototypes, budget PLA works; for precise or multi-color prints, consistency pays off.
What is PLA+?
A marketing term for modified PLA, usually tougher and less brittle. There is no standard definition, so properties vary between brands.
Do cardboard spools work in the AMS?
They can shed fibers or slip; many users fit adapter rings or respool. Check community guidance for your unit.
