increasing chamber temperature for ASA  

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.

RE: increasing chamber temperature for ASA

Thanks for the detailed explanation.

I’m running 7 Prusa XLs, so I’m looking for the simplest but most efficient solution that also scales well.

A PTC heater with air recirculation sounds like a very good idea — I’ll definitely test that approach.

That said, I suspect I’ll still need to insulate the XL enclosure with aluminum insulation mats to keep the heat inside as efficiently as possible, especially for long ASA prints.

A few questions for you:

Are you using the original Prusa XL enclosure? Did you seal or insulate the various holes/openings in the enclosure with the aluminum mats, or did you leave them open? Any issues with electronics or thermal warnings after running at ~55 °C for hours/days?

Wow, respect! That sounds like professional work!It should be efficient, otherwise energy costs will skyrocket.

That would be the simplest and most effective method.

Are you using the original Prusa XL enclosure?

No and yes. No, because I find the housing for the XL not only ugly but also too expensive. Yes, because I used an MK4 housing from Prusa to print my XL there.

Did you seal or insulate the various holes/openings in the enclosure with the aluminum mats, or did you leave them open?

In my test setup, I closed all sides. According to the LCD menu, temperatures rise to 70 degrees. Therefore, I would like to move the power supplies and the buddy downwards and/or install fans (just to be on the safe side).

Any issues with electronics or thermal warnings after running at ~55 °C for hours/days?

I had my reservations, but so far the test setup (without fans and without modifying the control electronics) has run without any problems.The heat sink temperature rises to 60-65 degrees Celsius for me.Additional fans on the sensitive components would be advisable.
