P2S Chamber Heater M2 with Air Purifier | MartilloTech for Bambu Lab P2S

It worked great for 6 hours it kept the P2S at 63 degrees instead of 60 which set off MC Module warning then after 6 hours it just died best ASA print i ever did with the P2S but the quality of there products is junk I ordered a cheap generic with digital control the 3 heat temperature sucks 40-45-60 the filament cooler was DOA stay away from Martillo expensive junk that doesn’t work

Superb customer service, extremely fast shipping and delivery to Europe! I got the package in a meticulous condition. The item is packed nicely and has a great quality. The manual is very well detailed and provides clear instructions and know-hows for the proper assembly! And the package even includes the filters and the filter material. Recommended! Thank you very much!

The official P2S lacks active chamber temperature control, which often leads to warping when printing engineering materials or large models. I saw MartilloTech’s P2S active chamber temperature kit was available, so I grabbed it right away to test. I also reinstalled the official exhaust fan backplate at the same time.
Installation isn’t too complicated—just follow the instructions. Once fitted, it doesn’t interfere with normal printer operation. In use, the blue light means cold air (perfect replacement for the stock left fan), and red light means hot air. Testing shows even heat distribution throughout the chamber and fast heating, making winter printing smooth and reliable.

Just testing it out, mainly printing with PETG. With the height riser open for ventilation and the glass top riser, the temp stays around 40°C. Closing all vents brings it up to 43°C. It would be even better if the unit could automatically adjust temperature and switch between hot and cold airflow.
After a few days of use, the results are really good—especially in this cold winter weather. Looking forward to seeing how it performs in summer. Print quality is amazing thanks to the consistent temperature. Installation was fairly straightforward and easy, and the non-destructive mount is excellent. It uses all the existing holes on the machine’s side panels perfectly, no modifications needed. Super well-thought-out design, thumbs up 👍🏻👍🏻

The biggest issue with printing large PETG and ABS parts on my new Bambu Lab P2S is warping. Even with a thick PEI plate, big parts still warp badly.
I originally wanted to DIY a chamber heater and temperature control, but I didn’t have time to mess with it, and I also cared about ease of use and safety. So I decided to go with a ready-made kit instead.
The Martillo unit is compact, easy to install, and keeps the chamber temperature stable. I’ve printed several large parts with almost no warping at all.
