I have purchased this chamber heater for printing ASA, ABS and other high temp materials. Sadly, the thermostat only goes to 50c, but I may hack it with ESP32 for MQTT and other control to 60c.
Has anyone else used such chamber heater and can share results? I find ASA warps for me with some prints, for example, even when preheating chamber using bed to 40C+
Sorry to hear you made this purchase. I looked at this and determined that the math just doesn’t support such a decision for an FDM printer. These were designed primarily for Resin machines. as the ad copy on Amazon states. I’ve been able to achieve 45C easily by simply applying bubble wrap around the outside.
I put these chamber heaters in the same category as filament dryers, that being, a lot of money for very little return. Hopefully you bought yours on Amazon and can get your money back.
I don’t mind, the purchase price ends up being around the same as DIY. I have not received yet, and have not tested.
I will try using it for some time and share results, it is returnable if needed from Amazon.
I am hoping to achieve 50C chamber temps and if not, I may look into trying the PTC element with 24V to see if heat output can be doubled. If not, I may aim for 100W heater.
Have you shared due to your own personal negative experiences with this unit?
Seems the chamber wattage is actually 380W from Wiki:
X1E FAQ | Bambu Lab Wiki.
Hmm. Yes, maybe too small wattage. I will try for some time and may look at other modules
Check out some of these homespun ideas from earlier in the year.
Throw a towel or sweatshirt over the printer, especially over the top glass cover. It will reach 60°C with heatbed set to 100°C for ABS/ASA without any heater.
Nice!!!
You sure you’re not from New England? Because they call that Yankee Ingenuity.
BTW: Here’s my version of Yankee ingenuity and I didn’t have to do laundry to get there, I just used envelopes bambu shipped my plates in and magnets. 
Ugly? Yes!!! But effective nonetheless.
I have been printing ASA with no issues with the stock x1c and no covers. I haven’t experienced any warping yet. 270 nozzle temp and 100 on the bed.
At the beginning I tried an ABS, which had extreme warping when printing on the engineering plate. I don’t know whether this is still a problem on the flexible printing plates today. Or updates for the printer have solved problems here. However, I now only print materials that have a strong tendency to warp on a rigid glass plate. The temperatures of the X1C are also sufficient for this. I also don’t need to heat it additionally.
I know this is an old thread, but I just added a chamber heater to my X1C and it’s great - looks almost factory. I got it from AliExpress for the princely cost of £35.09 - closer to £50 with delivery. It bolts under the side rail and comes with a lead that connects to the mains power bolts on the main PSU. Means taking the back off which takes a while but the look and function is great. It’s capped at 65deg to avoid any damage to the camera etc but reaches that temp pretty quickly. Good for printing PA etc and greatly improves the drying function. I’ve noticed that it even helps dry the AMS. Nice solution.
You can print PC in a stock X1 if you really wanted to - the print will be like breaking a twig, though
The reason you want the temperature above the 40 degrees an X1 will get to with zero modification is printing ASA or ABS at 40 won’t have any warping but will have poor layer adhesion - the reason you should print as close as possible to the Glass transition temperature of the material is to create strong bonds
The difference between an ABS print at 40 and 60 is huge
100 degrees? Perfect. But not practical on an X1
People that boast they can print ABS in an open frame printer are being a bit silly because they’re printing something so weak and brittle they’re throwing money away and don’t understand the need for a warm environment when printing high temp alloys
It’s possible if the printed parts are cooked in the oven at 100°C for 3 hours. But of course, the people who claims that wouldn’t invest in an enclosed printer, surely wouldn’t buy a proper oven to anneal ABS, ASA or whatever.
