Both print the same 256 mm cube, enclosed, CoreXY. The X2D (April 2026) is two printer generations newer: its chamber is actively heated to 65C where the P1S drifts passively around 45C, it adds an auxiliary nozzle for support or backup material, its AMS 2.0 chains up to 25 colors, and its Vision Encoder replaces the old first-layer guesswork.
The P1S counters with one argument, and it is a good one: $399. For PLA/PETG and casual ABS, the P1S does 90% of what the X2D does. The X2D case starts where materials get warp-prone (consistent ABS/ASA, PC attempts) or where the second nozzle and bigger color count actually change your output.
