I have tried every kind of setting I can think of to get threads right but just can’t do it. There is always a curl on the bottom of the threads. I have tried PLA and ABS. The best I got was with PLA slowed way down to 27 mm/sec 190 nozzle 63 bed 1. layer. Here is a photo of my best thread, still not as clean as I want it.
You folks with creator pros who can print this out and look better than this one shown please let me know your setting and or secrets. Thanks, Jim
Hi @jimdigs interesting, I’ve printed quite a few threads (on my FF Pro) around this size and haven’t seen this issue. I didn’t use any specials settings or tricks, and certainly no supports, although I did print dead slow around 30mm/s. What filament are you using (in terms of quality, storage, dryness, etc.)? Are you using any fan of any kind?
What I mean is look at the threads in the slicer (yellow view) and then again once you hit prepare to print and see how they look. Do they look the same as the actual print.
I am using hatchbox filament and yes I had the fan on 100%. I have always had overhang issues with this printer no matter what settings I try or supports I use. I was even printing slower than you.
Here are photos of what the file looks like before being ready to print and when being ready to print. They look fine to me. I think its something with my printer.
Were you using the fan with ABS? I wouldn’t normally use any fan with ABS, although to be honest I can’t think of any effect with the fan that would affect only that part of the thread.
It’s as though the first few layers of the upper halves are not reaching the edge. What’s your fill setting? I can’t recall exactly, but I believe my fill was pretty high for this bolt, 60% or higher. It may be if you’re using a lower fill that when the upper part comes to lay down there’s not enough “support” close to the edge and the filament shrinks in a little, as it tends to on curves if not well adhered to the surface/layer beneath it.
Nope, no fan with ABS just the PLA. I have tried the fan with ABS before with some success. Which fill setting exactly?? There are so many on Simplify. Which tab is it under? Thanks
Yea, I’d go a lot higher than 20% infill. What perimeter settings are you using? Again, I believe the last time I printed a thread I used 3 or 4 perimeters…
Well, I printed it and put it together since I needed it actually and forgot to look at the threads! It went together without and effort so it was decent.
I printed in black ABS with pretty much defaults. I think 3 shells and slowed it a bit. I’ll go take it apart later and have a look.
Hello!
I’m a student trying to innovate within the growing 3-D printing industry and I was wondering if anybody could fill out this quick survey to help me gather some data. Any responses are helpful, Thanks!
