So I’ve been on an ABS kick, I’ve upgraded the crap out of my ender 5 just for this purpose, better hotend, better build plate and heaters, full enclosure, the works. I’ve had the worst luck with every single print warping no matter what. That is until I learned about ABS juice, suddenly my prints were gasp Sticking to the plate. I know, amazing. Soon as printing all sorts of little things, flat things, tall things, skinny things. But there’s one thing I hadn’t tried, big things. Not I decided to go for broke, and I don’t exactly know what the difference may have been here, it might be that the ABS is about a year old even though I kept it inside of a cupboard it may have still absorbed some moisture or something

. But I get about halfway through this print, and I swear to God I was pretty sure that it was sticking to the build plate just fine when I hear some cracking. I look over and I see all these little lines starting to form, I’m about halfway through and there’s no way I have enough ABS to print the rest of it so I figured just wait and see what it comes up with. Now I’m pretty sure I can make some ABS slurry to maybe fill in the cracks and make it usable enough for my girlfriend, it’s just a book rest. But I would like to figure out what happened here and how to prevent it in the future.

Do any of you guys who have more experience with abs know what might have gone wrong?

Main variables for this print are ABS obviously, 15% infill, 110⁰C build plate, 250⁰c hotend, 240⁰c near the end to try and lower the temperature differential to try to prevent the layer splitting. Entire print speed was set to 60steps and 20 steps for infill with 110% flow rate.

Entire print was . 28mm layer height

    Large, thinner objects in ABS are a huge challenge, even with an enclosure. I pretty much gaveup trying to print A Nevermore Max in abs for the frame, walls aren’t super thick so it’s super warp prone. I tend to use petg for prints like that.

    That’s a really low hotend temp unless you meant 250 and 240. You could try dropping cooling to try getting layers to adhere better but I’d really consider a different material.

      Whoops yeah I meant 250, and yeah it’s unfortunate, I had finally brought out this ABS in an attempt to finally make use of it, but it may have to stay in storage for smaller prints

        It’s still a fantastic material in my view. I find it handles overhangs nicely and handles higher printing speeds. It does give off some nasty fumes though, my printers live in my garage and I have carbon filters on both of them, still don’t like being out there while printing it unless I can open the doors to the outside.
