P1S Chamber Heater for Bambu Lab P1/P1S - 140°F (60°C) Heating & Filament Dryer

P1S does not actively heat the chamber by default. For larger ABS/ASA/Nylon prints, temperature swings can increase internal stress and raise the chance of warping, corner lift, or layer splitting. Active chamber heating helps keep the enclosure in a more stable range so layers fuse more consistently.

MartilloTech’s chamber heater for Bambu Lab P1S adds active enclosure heating to help stabilize a 40–60°C (104–140°F) chamber range for improved ABS/ASA/PETG/Nylon printing (reduced warping and layer separation in many setups). It uses IR printhead detection for automatic on/off (no Wi‑Fi or app), provides strong internal air circulation, and includes filtration media (HEPA + activated carbon) to help reduce particles and odor/VOC byproducts during printing. It can also be used as a filament dryer up to 60°C, supporting up to 4 spools (4 kg) with AMS compatibility. And select 110V or 220V to match your region.⁠

Automatic IR on/off that follows printing—no app/Wi‑Fi and less “forgot to turn it off” risk.⁠
More stable chamber heating in the target range to support ABS/ASA/Nylon printing.⁠
⁠Built-in filtration media (HEPA + carbon per listing) instead of relying on separate room-air filtration⁠.
⁠Non-destructive install with included mounting accessories; no permanent printer modifications.
