What settings can I change to print faster without affecting the print much?
Hi Everyone!
I've had my Prusa mini about a month now but each time I do a print it feels like some of the smaller items are taking much longer than they should.
I normally make these changes to the print settings for top/bottom solid layers down to 3 and 3 (someone told me i dont need the default 5/6 thats usually in prusa slicer)
Also, I change the infill to 15 or even 10% when i know i dont need it too strong
Layer height I normally leave it 0.2mm also, i dont usually print lower unless i want it more detailed.
Supports when they're needed a pop-up comes up to enable "detect bridging perimeters", and i always turn that on because im not quite sure, but when supports are definitely needed, it takes much longer and sometimes it's really hard to remove them but that's another issue in itself. I set Contact Z Distance at 0.2 (detachable) for the supports. Not sure if I can use something else to help speed up prints with supports also?
I'm using Prusament Galaxy Black and before this i was using Overture, but the filament made no difference in the speeds I'm seeing from PrusaSlicer.
What options can I change to speed it up?
I even change the speed to 105% sometimes on the printer, but that only saves 10-20minutes sometimes and doesn't even make sense.
Here's the latest print I'm trying: https://www.thingiverse.com/thing:2763553?fbclid=IwAR2l3AOXRd7STDGL1lDhxp_QT8FSazLYRUal6-kR6uOoeGEB5rHH5S9-9sg
I picked a row of 4 spice rack holders, then another 2 and 2 on the corners as well. Total of 8 on 1 print.
If I do just the row of 4 on 1 print, it shows 5hours to print it. And this doesn't even look like a very difficult print. Should it take 5 hours for a print like this for 4 spice rack circles? If i put the other 2 and another 2 on the corners to fit 8 spice holders, it's a 10h4min print.
Any help would be appreciated.

I would suggest you take a look into larger nozzle diameter. Prusa Slicer has profile for MINI with 0.6 mm nozzle diameter, besides fine 0.25 and standard 0.4 mm nozzle. It can speed up your print quite significantly, the drawback is that layer lines may be a bit more visible if you use bigger layer height. If you don't care, you are golden.
Here's a good article on it, includes video: https://blog.prusaprinters.org/everything-about-nozzles-with-a-different-diameter_8344/
MINI is compatible with standard E3D v6 nozzles.

I wasnt aware of this. I didnt know how large i could go. As long as the prints dont get ruined, it could work for the household stuff i make.

Thanks for your answer. I saw that i have an 0.4mm nozzle and ive been doing 0.15 or .20mm usually. I just put one of those prints up to 0.35mm and immediately 40% of the time was cut.
I guess this is the main answer to the speed factor without having to increase actual speeds and risk a ruined print.
I ordered 0.25 and 0.6 as well. Thank you again!

I wonder, why they do not have the profile for 0.35 preconfigured in prusaslicer with the mini? I have seen the MK3 has that profile but the mini only has 0.25 as a system profile, anyone know why ?

I actually only saw .20... I manually changed some prints to .25, .30, and .35. I didnt know much about printing but im learning as i got. I even order a 0.6mm nozzle as well... It is strange it's not preconfigured in prusaslicer for the larger sizes.

Something else to look at is number of perimeters. You can try reducing them. Or increase them and reduce infill. Often times you can actually get a stronger part with thicker walls and 0 infill than you can if you have thin walls and more infill.

@darcshadow
I never change that. Its usually set at 2. I'll see on some prints if increasing perimeters and decreasing infill helps on the time also. Thank you
