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.
Oh yeah same volume, my garage isn’t climate controlled and I live in southern Ontario so it’s not exactly cold in the summer, it contributes to the chamber temps for sure. That said, on a day in the high 20s I’ve seen 65 ish chamber temps, have a long running print going right now and it did cool off some last night to 58.5 with a 100c bed temp, doing some large abs prints that to be fair are designed to minimise warp but I find north of 50 pretty much solid for a lot of my prints, lots of variation between filament manufacturers as well from what I’ve found, if one works well I tend to stick with them for the bulk of my material. Also considering the bubble insulation, specifically for the winter, I actually kinda sorta want to do a nomex or other fr material sleeve though, was half joking about the cozy idea but it’d do the trick and be easily removable.
Frame gets very warm, I’m actually mildly concerned about the adhesive on the foam tape as well, had an issue last summer with 3m adhesive tape failing in the heat of just the garage. I bought some nomex gasket material meant for smokers and the like that I’m adding to the list of things to try, chamber temps already cause the cheap interior humidity/thermometer LCD to error, seems to only be good into the 50s, but it’s just there for quick reference and I have a chamber thermistor on the gantry now anyhow.
Edit: current temps and fan settings if curious, I’ve for a spool of polymaker polylite abs I’m using up in there, have had really good results with Matter3D Performance ABS which is a manufacturer out in BC, had next to no odour and prints really nicely. Have had good results with all of their material.
Thanks for taking the time to type out a reply. Using my hot end as my chamber thermistor (hot end off, hot end fan max), after soaking for ~1 hour, my chamber tops out around 45c. My printer does have the filter + 2 extra bed fans, but other than that it’s a fairly vanilla 2.4, complete with acrylic panels. Your post inspired me to work on panel mounts for the ACM panels I’ve had next to the printer for a few months.
How did your foam tape fail? Thankfully, I haven’t had that happen to me yet. I’m going extra wide on the foam tape to put the radiant bubble insulation on the inside of the panels. This is the real reason why I’ve been putting off mounting them - I needed to modify the mounts I’ve been previously using. I’m also not sure if the magnets will hold the extra weight, so I might need to get… creative.
What thermistor are you using for your chamber?
I tend to do what you do - find a brand of filament I like and stick with it. That said, so far I’ve only used Polymaker’s polylight ASA. What was your experience with Polymaker vs Matter3d? Polymaker puts 3kg spools up for very cheap every once in a while, but I’m happy to pay more for an easier to print filament.
Yeah the acm insulated better than I expected, probably the pu layer? As for the tape It just kinda fell off the wall, it’s not the best surface, old concrete board I think, has a rough surface, was for powerbar cables and the power bar itself, was super secure when I put them up but they came down about 6 months later, they’re all up with wall anchors now. The foam on the panels hasn’t failed yet, used different stuff on the doors and its adhesive kinda seeped out, not happy about it though, been meaning to do something about the doorgap too so figure I’ll do all at once. I need to do some panel mounts changes too,
I moved the touchscreen to the top of the printer because I was tired of hunching over, I ran the cables under the panel and added some extra foam tape around it and used an extra clip to squish it all together, it works but want something better
I have a bunch of spare hotend thermistors, used one of them, this printer’s using a pt1000 anyhow so was fine using the one I swapped out.
I use a reference more than anything.
I’ve gone through a bunch of polylite abs, which prints pretty well, but it stinks, may actually be one of the stronger smelling abs I’ve printed with. That’s the immediate difference, the Matter3D stuff has way less smell, almost none actually, need to practically stick your face right up against the door for a bit. Print wise, I’ve just used the extrusion multiplier I use for all abs so not tuned a profile yet, kept up with a decent print speed and it can go hotter (if I recall wants 235-270), quality is solid, very dry out of the bag, does come on plastic spools though.
