What is PLA+ and how is it different from standard PLA?
PLA+ is a toughened PLA grade. The base resin is impact-modified while the material is compounded, instead of being filled with mineral or fibre, so a printed part absorbs knocks rather than cracking along layer lines, while printing behaviour stays inside the normal PLA range: it still runs on an open-frame printer with no enclosure, and it still behaves like PLA on temperature and stiffness. The trade-offs are the usual PLA ones: it is not a high-temperature material and it is not meant for continuous structural load. For parts that sit in a hot car or carry sustained load, PETG, ABS or ASA performs better.
