PLA, PETG or ASA: which plastic is right for a plant label that stays outside?
PLA is easy to print and looks good. It softens near 60 degrees C. A label in a hot greenhouse, or on a sunny sill, can bend.
PETG takes more heat and moisture. It is a good default for garden labels.
ASA takes heat and also resists UV light. It is the best choice for a label that stays in direct sun all summer. It prints best in a warm, closed printer.
Whatever you use, keep the strokes at least 0.8 mm thick for a 0.4 mm nozzle, raise the text 0.6 to 1 mm, and make the letters 8 to 10 mm high for a pot. Print one test label and leave it in the rain for a week.
