Bottom Line
💰Elegoo Neptune 4 Pro saves you $539 — choose it if budget is your primary constraint
🏠Anycubic Kobra S1 Max is the only choice if you print ABS, ASA, PA, or PC — those materials require an enclosure
Materials
PANylon — strong and wear-resistant, needs dry storage
PA-CFCarbon-fibre nylon — very stiff, abrasive to standard nozzles
PCPolycarbonate — extremely tough, challenging to print
PLA-CFCarbon-fibre PLA — rigid matte finish, more brittle
PETG-CFCarbon-fibre PETG — stiffer than PETG, easy to print
PET-CFCarbon-fibre PET — rigid, dimensionally stable
PVAWater-soluble support — dissolves for complex overhangs
PLAEasy to print, no enclosure needed — everyday parts
PETGTougher, slightly flexible, moisture-resistant
ABSHeat and impact resistant — needs enclosure
ASAUV-stable ABS alternative — outdoor parts, needs enclosure
TPUFlexible rubber-like — phone cases, gaskets, wheels

Why buy each?
Anycubic Kobra S1 Max
350×350×350 mm large-format build volumeOne of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.
65°C active chamber heating at scaleMaintaining 65°C across a 350×350 mm chamber is a meaningful technical achievement — ensuring consistent results for ABS, ASA, and PA across the full build plate.
Anycubic ecosystem continuityThe S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.
Elegoo Neptune 4 Pro
Klipper firmware out of the boxThe Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.
500 mm/s at budget pricingCompetitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.
Auto calibrationFull automatic bed leveling reduces setup time and calibration friction.
