PLA+ - Printing speed - 30 - 70 mm/s

PLA+  stronger PLA without complications

PLA+ is a modified version of PLA with improved mechanical properties; compared to standard PLA it is less brittle, but heat resistance remains similar and varies by manufacturer.
Advantages: easy printing like PLA, higher toughness, better layer adhesion.
Disadvantages: still low heat resistance, inconsistent properties depending on brand.
