I’ve been using (attempting) to use abs to build some parts that will be housed in an electronic enclosure of sorts, which can get pretty hot. Maybe around 90-100C at max. It’s for a 6 bay battery charger for my uav and I haven’t actually measured the heat - it’s just a rough guess (there is a fan to exchange air so it might not get that hot). This has been a long project. I have 2 pieces that are 300+ grams/15 hour prints and individually take up the entire bed of the Taz 6. They are 2 halves to a single part.
I’ve been trying to use ABS for these, but they warp pretty badly no matter what I do. The first 15 or so layers are pretty good, but then the corners start curling up after a few hours. I’m using a 10 line brim and can’t increase it any more as there isn’t space. These 2 parts connect together to make a surface that fits in a Pelican 1550 case. They need to be flat with no/VERY minimal warping. Ive had the heat bed set to 110-115C and tried various nozzle temps. I think my first layer is pretty bang on. Spent several hours calibrating the extruder, z-height, x/y/z axis and on a 40mm cube I’m at like 40.02 - 40.04mm within all axis.
The only reason I am trying to use ABS is its high heat tolerance. I really don’t want to build an enclosure to print these. So, does anybody have a recommendation on a different filament that has minimal warping and is pretty high temp resistant? I’ve read that PLA can warp just sitting in a hot car. They need to be strong and take heated inserts.
The abs works really well for smaller parts, just not these large ones that take up the whole build plate. Yesterday it was really hot here (around 100). I would have thought that extra heat might help a bit but it didn’t. I’ve gone through 2kg of abs and can’t perfect it. So, I’m looking for a good solid alternative and would appreciate any suggestions. I don’t have a very wide exposure to different filament types.
Edit: just to add I’m using Village Plastics ABS from the lulzbot store.
