What to feed the Elegoo Neptune 4 Pro
The Pro's addition: ASA
Same core menu as the Neptune 4, plus ASA for parts that live in the sun. Polymaker's PolyLite ASA is our first-ASA pick: UV-stable and more forgiving than most of its family.
Speed spools
Rapid PLA+ and Rapid PETG exist for machines like this one. The PETG asks for a pre-print dry (60 °C for 8 hours) and pays you back in quick, tough parts.
The fine print
ASA and ABS want 90-110 °C beneath them, and the Pro's 110 °C bed covers that range fully. Ventilate both, always.
