The P2S handles everything most users will ever need: PLA, PETG, ABS, ASA, TPU, and even PA. The H2S adds active chamber heating and 350°C nozzle capability for materials that truly demand it. PA-CF, PC, PEI, and similar high-performance engineering composites.
The 1000mm/s speed on the H2S sounds impressive, but real-world print times aren't 2x faster than the P2S, most of the speed advantage is seen in infill and travel moves. For detailed prints, both machines operate at similar effective speeds.
