- Which is better for printing ABS and ASA?
- The P2S. Its enclosed chamber, 110 °C bed and carbon filtration control warping and fumes. The Neptune 4 Plus is open frame, so large ABS parts are likely to warp and smell.
- Which has the bigger build volume?
- The Neptune 4 Plus at 320 × 320 × 385 mm. The P2S is 256 × 256 × 256 mm, so the Elegoo fits noticeably larger single-piece prints.
- Is the P2S worth $170 more?
- Yes if you print engineering materials or want AI failure detection and an enclosure. If you only print PLA and PETG and need size, the Neptune 4 Plus covers it for less.
- Which is easier for a beginner?
- The P2S. Reviewers describe intelligent calibration and nearly problem-free printing. The Neptune 4 Plus is mostly pre-assembled but needs more tuning and has more reported hardware faults.
- Can the Neptune 4 Plus print abrasive filaments like carbon-fiber nylon?
- It can reach 300 °C, but its brass heating block wears faster with abrasive filament. Buyers also report quality drops and spaghetti failures after switching to ASA CF. The P2S ships with a hardened steel nozzle.
- Which is faster?
- The Neptune 4 Plus lists up to 500 mm/s with 12,000 mm/s² acceleration, defaulting to 250 mm/s. The P2S uses CoreXY motion for high speed but does not publish a top figure, so real-world results depend on the material.
