Chamber Heater - Externally Mounted

A clean, polished-looking modification to print ABS, ASA, and Nylon filaments without any warping. PPA-CF & PAHT-CF print with greatly improved layer adhesion.

Requires no internal wiring inside printer, while adding minimal bulk. Housing hanging off the side of the printer will measure 8.4 cm W x 6.5cm H x 8.7 cm or 3.4in W x 6.3 in H x 3.4 in D. Can be installed on any brand or model of enclosed printer with enough surface area on a side panel to allow the enclosure to be mounted after drilling large (50mm / 2 inch) holes in the printer's side panel. Was designed for the P1S and X1C.

Will hold any temperature you set it to via the wired remote, which is seen in the photos secured over the door with double-stick tape. Displays current temperature at the air intake, can be set on a timer or to run continuously. Maximum temp is 70C.

Profiles are included for ABS, PA6-CF, and PAHT-CF / PPA-CF, which all have the heat resistance needed to house this chamber heater. PETG and PLA will melt at the temperatures the heater produces, and must not be used.

The template for drilling the printer's housing prints in ordinary PLA.

• Requires drilling two large 2" holes in your printer.
  •  (Use either a hole saw or cut them with a dremel or jig saw. Replacement side panels for the X1C and P1S are available for under $50, so this is not a permanent, expensive mod.)
• Uses 8 x 3mm heat-set inserts\, size 3x6x5 or 3x8x5.
• Uses 8 x 3mm screws, 10 to 12mm long.
• The housing in these files fits the following heater:

This is not a wireless/bluetooth/intergrated solution. I prefer manual simplicity and the ability to retain functionality when offline. Manual on/off, set the desired temp, and activate the timer if desired. That's it. You will need to be present at the beginning of each print to start the heater.

Takes no more than 20 minutes to warm the printer to 55-65c if you set the bed to 100C and turn the heater on.

Factory plastic internals on a Bambu are ABS or similar materials, which has a heat deflection temp of 80C. The heater used in this project has a maximum output temperature of 70C.
