I've been doing functional ABS and ASA lately and had a couple very annoying warpage spots. One was a total failure. (We won't talk about the other 3 failures that were wet out-of-the-box Bambu ASA...)
The X1C is definitely nice, but the all aluminum-and-glass side panelling has a sometimes-unwanted side effect: thermal conduction.
The aluminum sides are so conductive that they do not allow the chamber temp to go above 40C, even after a couple hours of heat soaking the build plate at 100C before starting an ABS print.
Enter: One random bath towel. doesn't look like much but just covering the three sides with a thin layer means it's good enough insulation to get the chamber up to 50C now! And the ABS parts look better than ever- every C counts.
Interesting that the extra 10° makes such a difference for ASA and ABS.
I recently started printing with ASA in my enclosed MK4. I might have to try this.
It makes all the difference, especially on asa. They're so sensitive to chamber temp and accidental fan use it's actually kinda nuts. I'm really happy with the part's physical strength and behavior of course but it's a very different beast compared to PLA, which will basically still make a successful print even if half of the model isn't even touching the bed lol.
If you can get the chamber to 50-60C it's ideal for those. 40 you can often get away with but on larger parts it is marginal at best.
And temp stability too which is just as important.
The slightest draft of cold air and my ABS prints go bad fast
I was successful with ASA using my MK3 inside the IKEA LACK enclosure. Although those were small parts, not subject to much wrapping.
I did something similar to my 2.4:
If you dig through my post history you'll find a thread about it. I've been meaning to mount better insulated panels for a while now.
Yeah, even the ACM panels with bedfans are enough for it to get toasty, I've seen mid 60s during the day, I'll probably put insulation on it at some point as well for the winter.
Someone needs to make a nomex cozy for them.
How large is your printer? Mines 350mm^3 in terms of print area, so I have a lot of surface area on my panels.
I am planning on going ACM + that bubble radiant insulation on the inside. I really hope I'm able to hit 60 °C chamber. That's what all of this stuff thrown on the printer got me to and I had zero warping with a pretty large ASA print.
Oh damn, you went farther than I did lol. Looks like my girlfriend when she bundles up for winter.
Yeah after seeing how much of an improvement I got with just a single towel, I want to make some neoprene insulated sheet panels to clip on the outside of this printer almost immediately.I'm planning on swapping my acrylic panels for ACM panels and adding a layer of radiant insulation on the inside. 60 °C eliminated ASA warping. You can also run fan with ASA as your chamber temp goes up, which is kind of nice. Thankfully my panels all attach magnetically, so I can pull the top off easily when printing things like PETG.
I use a brewer's belt with my resin printer when it's cold. It has made a big difference. Keeps the printer warm without getting too hot.
Mm, heat tape with a thermostat, that does sound useful for a resin printer. I've been rolling around active chamber heating in my head for a while to hit the magical 60C and that could be one option for it.
Interesting! I haven't had issues with ABS at stock temps in my X1C - 90C for the build plate - and I print a lot of large flat ish designs. I have had more trouble with PETG warping, and for HIPS I have to crank up the first layer to 110, then 100 for subsequent layers of it won't stick to the Engineering Plate with glue stick at all.
My chamber temps do tend to be a bit lower, since I have an exhaust fan hooked up the carbon filter fan output to vent outside since ABS and HIPS fumes are nasty.
But yes, I've found 10C or so can make a huge difference when things do go south, it just hasn't been an issue on my X1C for ABS, fortunately. Interesting to see how much a towel improves your chamber temps though!
Overall I love my X1C, one of the best decisions I made, don't miss my old kludgy FlashForge Creator Pro and all its quirks one bit.
IME abs is just better at "sticking" with good glue and proper bed temp than petg is, not sure why but I've had tons of petg just unstick and start to warp from that. (That was with college public printers though so abused pei sheets and wet filament was very likely...)
I also think the x1 was the best choice I've made in a while. Man this thing is productive.
They take a shower now? Wow! And do you need to tell them a little story before they go into sleep mode?
