increasing chamber temperature for ASA
Hi everyone,
I’m looking for practical tips to increase the chamber temperature on the Prusa XL, or to hear what solutions others are using to print ASA more reliably.
Current setup:
Prusa XL with enclosure Chamber temperature tops out at around 35 °C ASA prints are okay, but I’m planning to switch to larger, long ASA prints, and I want to avoid failures like parts lifting off the bed after 15–20 hours
Why I’m asking:
I also run a Core One L with an actively heated chamber Printing ASA at ~55 °C chamber temperature gives clearly better and more stable results I’d like to get closer to that level of reliability on the XL
What I’m specifically interested in:
How do you raise or stabilize chamber temperature on the Prusa XL? Any enclosure mods, insulation, airflow changes, or external heating approaches that work well? Are there setups that reliably handle large ASA prints without overheating the printer electronics (e.g. Buddy board issues)?
Thanks for sharing your experiences.
RE:
With my Prusa XL with enclosure, I can achieve a stable temperature of 55 degrees for hours without external heating. For me, the heating is the print bed. It takes about 10-15 minutes for everything to warm up.
Unfortunately, I can't send you any pictures yet because my project isn't quite finished, and I'll only publish my post about my enclosure here when everything is ready.
I used insulation mats that are actually intended for radiators. Two layers of aluminum with insulation material in between. here a link:

If that's too much work for you, you can also install PTC heaters that work with the air in the enclosure. So no air is drawn in from outside, but rather a recirculation principle is used.
However, there are already mods that have implemented controls for enclosure heating.
