The $399 enclosed workhorse against the $1,199 engineering machine

Which one should I buy?

Quick answer: Most people should buy the P1S at $399: same enclosed CoreXY concept, proven, and $800 cheaper. Pay for the H2S only if you need what it objectively adds: a much larger 340 x 320 x 340 mm build volume, a 350C nozzle with an actively heated 65C chamber for engineering materials, double the speed, and the optional laser module.

P1S

  • You want the cheapest enclosed Bambu, full stop
  • Your prints fit in 256 mm and stay in the PLA/PETG/ABS range
  • The $800 difference funds an AMS plus a lot of filament

H2S

  • You print engineering materials (PA, PC, filled) often enough to need 350C and an active chamber
  • You need the 340 x 320 x 340 mm volume
  • You want the laser/cutting option or 1,000 mm/s throughput

Same idea, different league

Both are enclosed CoreXY printers, which is why this comparison comes up so often now: since Bambu's open-ended discounts, the P1S at $399 is the cheapest enclosed Bambu and the H2S at $1,199 the entry to the H series, so the gap is exactly $800. The P1S covers PLA, PETG, ABS and ASA in a 256 mm cube at hobby volumes. The H2S is a different class of machine: 76% more build volume, 1,000 mm/s motion system, a 350C hotend, and an actively heated chamber that holds 65C instead of drifting around 45C.

The practical question is materials and size. If your parts fit in 256 mm and are mostly PLA/PETG with occasional ABS, the H2S buys you little. If you print PA, PC, or filled engineering filaments regularly, want big single-piece prints, or care about the 10W laser option, the H2S is the cheapest Bambu that does all of that properly.

If you are stretching past the P1S but the H2S feels like too much printer, the in-between steps are the P2S at $549 (newer P-series, 600 mm/s) and the X2D at $649 (active 65C chamber in the 256 mm format). Both close part of the materials gap without H-series pricing.
