Prusa MK4 is an open-frame printer — for ABS, PA, and PC you need an enclosure and active heating. iHeater Kit 200W fits inside the Prusa Enclosure and heats the chamber properly, eliminating warping and layer separation that cold air causes. Connects to the MK4 via USB as a Klipper external MCU, or via Wi-Fi through iHeater-Link. Trigger mode starts heating with the bed — no manual steps. Two firmware options: Standalone (buttons + LED, no PC needed) or Klipper integration.
iHeater Kit is a DIY bundle for assembling an active heated chamber system for a 3D printer. It helps maintain stable temperature inside a closed enclosure when printing engineering plastics: ABS, ASA, PA, PC and other materials sensitive to print conditions. The bundle can work with Klipper, Bambu Lab, autonomous firmware, and can be controlled through an app or web portal.
When printing engineering plastics, not only nozzle and bed temperature matter. If the chamber stays cold or the temperature inside the printer is unstable, the part can layer separate, deform, lift off the bed or lose strength between layers. Active chamber heating helps create more stable conditions for printing ABS, ASA, PA, PC and other materials that need a warm enclosed environment.
Assemble iHeater Kit and install it inside the closed enclosure of your 3D printer according to the instructions.
Use iHeater with Klipper, Bambu Lab, standalone firmware, app or web portal.
The system helps maintain chamber temperature and creates more stable conditions for engineering plastics.
Helps maintain the necessary conditions inside a closed enclosure for printing.
Reduces the risk of layer separation, lifting and issues with large parts.
Suitable for ABS, ASA, PA, PC and other materials that need a warm chamber.
Works with Klipper, Bambu Lab, autonomous firmware, app and web portal.
Control board, temperature sensors and connectors for connecting main system components.
Heating element and fan create a stream of warm air inside the chamber.
Fasteners and assembly elements are included in the kit. Printed housing parts are not included.
Helps create a warm environment for printing parts without deformation and liftoff, ensures best layer adhesion.
Suitable for materials where stable print conditions inside the chamber are important. Allows printing PA and PC to get parts of the required quality.
Used in printers with enclosure or self-made closed chamber.
Assembly, connection, flashing and setup instructions.
Klipper support, standalone mode and future project updates.
Forum, Discord and Telegram for questions, user experience and installation examples.
The project is maintained by the author: documentation improves, updates come out and new materials appear for the community.
Suitable for closed FDM printers or printers with a self-made chamber. Important that there's space inside for safe installation.
Yes. The kit can work autonomously and can also be controlled through an app or web portal.
Control is done through autonomous firmware, mqtt connection with the printer, app or iDryer web portal.
All necessary components for assembling an active chamber heating system. Printed housing parts are not included.
It's a DIY kit for self-assembly. There's documentation and community support for installation.
Choose 110V or 220V for your electrical network voltage and region. If in doubt — better check before ordering.

After purchase, you're not left alone with the kit: iHeater Kit has documentation, firmware, instructions and community support.
Before purchasing, make sure that this information is sufficient for assembly, flashing and launching the device.
iHeater Kit uses multiple protection levels: board fuse, thermal cutoff and firmware temperature control. This helps shut off heating in case of malfunction.
