8.5 day, 1242.5 g print - Am I tempting fate? - Questions

Postby red » Fri Jun 14, 2019 4:47 pm

Hey folks - Newish Pro2 user here. I've got a two piece print that will be my biggest as of yet. I will be using Raise3D PLA on High Quality. Originally I was going to print the parts separately, but have managed to squeeze them in together. By itself, the largest piece was going to take 178 hours, so I figured another day with them combined wouldn't kill me.

That said, yikes that's 8.5 days of nail biting. Not only do I fear print failure halfway in, I'm concerned about swapping filament spools. I know the printer will detect the first spool running out, stop and park the printhead in preparation for a reload and resume, but I'm concerned about that creating an artifact layer when the print resumes with a new spool.

Just looking for a gut check, and opinions would be greatly appreciated. If I don't go this route, I will just print them separately.

Thanks.

Put an aerobed on the floor near the printer.

Haha, don't put it past me. :) I've done just that with a large run, for multiple consecutive day/nights. Wake up 3 am, remove the prints and back to bed, repeat at sunrise. Oof.

I had a print fail on my Pro cause filament run-out detection didn’t work, what happened was the end of the filament got stuck to the spool and it kept grinding and printed in air. That was with a different brand of PLA, but just a warning.

I would be interested to see it run this print without any issues, you MUST keep the AC on if your in a hot environment cause their extruder tends to get clocked with pla because of its bad design, I know their PLA can take more heat but just another warning.

Oh man. My print room is operating at around 75 F at 41% humidity. Unfortunately, I don't have the ability to use AC. My studio is basement level, and the idea of installing a window unit makes me nervous. That said, thank you very much for the heads up. I will at least run it without the top cover on.

I bet overall time could be reduced a lot! You may use light supports(10-15%) but turn it to 30% and with dense right before print a surface... You may change infill from lines to rectangular.. (+ bottom and top layers too).
You may not to use raft. And so on :)

I wanna try to slice and calculate :) May I ? ;)

I would be curious to see what you come up with. I'm using a lot of support in addition to dense support layers, in order to ensure surface quality. When printing fewer supports (closer to what the automatic support gives) have have had poorly formed undersides, drooping, etc.

Also, I have made the supports so dense to prevent support "islands" from being knocked over during printing, which has happened a number of times in the past. I would rather have a long print that uses up a lot of material, than have a failure.

I can PM you the .idea file. via a dropbox link.

My longest print was an 11.7 day print and it turned out perfectly. If the STL file is good, the supports are good, and the template is good, then you're good!

I'd post pictures, but it's under an NDA right now. I'll admit I had shorter nails when I pressed the print button, but after the first day or two, I left it alone checking on it between once a day to once every 3 days. That said, results will absolutely vary but so long as you're not doing anything funny with the plastic, you'll be fine.

I do have some pictures of a PLA and polycarbonate wheel in the print settings forum. One of those pieces took 4-5 days (the polycarbonate ones). I've improved the printing since then too. Just takes time, patience and trial and error!

I got it down to 171 hours. Just under a kg. Starting my print today.

Hey Dex - Do you mean 10-15% infill ratio? And by 30% do you mean Dense Support Infill Ratio?
