PLA+ - Nozzle type (recommended) - Brass (Standard)

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.
