PLA vs ASA: which should you buy?
Choose PLA if you want the easiest printing, with the fewest failed prints; or your printer is open-frame: PLA doesn't need an enclosure.
Choose ASA if the part has to survive heat: ASA holds its shape to about 100°C, against 57°C for PLA; the part needs to bend or flex without snapping; or it will live outdoors or in sunlight.
On price, a typical PLA reel costs £13.99 per kilogram on Amazon UK and Eryone UK right now, against £17.99 for ASA.
The figures are typical values from manufacturers' data sheets (Polymaker, Prusament, Bambu Lab); individual brands vary, so the range on the reel always wins.
