Up mini printquality
Up mini printquality
Hello,
My up mini is printing inproper at the moment.I made a box with walls of 2mm and the layers are not stick to each other.There is a gap between the layers.The fill is set to the smallest.I calibrate the platform perfectly.When I received the printer the prints where fine.Can anbody help me?

Re: Up mini printquality
What is the wall thickness of the model ?

Re: Up mini printquality
rotate the model 45 degree in Z only then print.

Hi,
Are you sure unchecking the shell option check-box and/or unsolid model check-box ?
One more thing you must initialize your printer before every print job.
hope it helps,
Oral

Re: Up mini printquality
Thank you all for your replies!The walls are 2mm thick.I have tried to rotate the part 45deg and yes the print is much better now.Thanks Drew.

Re: Up mini printquality
Also there is an interaction between layer height and the fill that occurs in thin walls and it's not always that smaller layers is better so some experimentation with layer height can yield improvements when rotating an object is not an option.

Re: Up mini printquality
Is this a bug? I have this trouble too. So sad ((
Test print. Walls- 2mm. What you think about?
Rotated on 45 deg. But present holes in the walls again.Test print. Walls- 2mm. What you think about?

@ SiberainTiger: Are you using the latest v20 software?
Always breath out on the way UP

Yes. UP 2.0, ROM 6.060, Firmware 3.06.

Re: Up mini printquality
It's not so much a bug as it is a limitation of FDM 3D printing. It is hard to infill between two walls that are too close together. A little closer and the walls will collide and you don't have a problem ... a little further and the walls can fit infill between. By rotating to 45 deg as Drew suggests its making the infill line longer (it crosses the walls diagonally) so it tries to infill where it otherwise wouldn't.
The magic distance varies with layer height as discussed so as well as rotating you can adjust your layer height as an option. Lower layer height may improve the infill by squeezing it in to a smaller space ... larger layer height may make for wall collision and fix your walls by allowing them to overlap a little. So experimenting is the key.

Re: Up mini printquality
Thanx for answer, roller. This limitation present on other models (not up)?

Yes, you see the same limitation in all FDM printers. Some software does some things to deal with it better but I have never seen software that never does it (thought I wouldn't be surprised some of the more expensive commercial printers have software smart enough to avoid it) .. so you will see it with just about every printer. There will be a sweet (maybe sour) spot of thickness that tricks every printers algorithm into printing two perimeter wall without some adjoining infill. That thickness varies depending on number of perimeters walls, layer over width setting and in turn layer height. You can get past the problem in an open source printers by manipulating some of those settings that you can't change on an Up where we are limited to just being able to alter layer height... but you have to do so by experimentation and changing those setting will often have ramifications for print quality somewhere else in the print.
Personally, when I need to solve these issues I will widen the walls 0.5mm if I can get away with it and only resort to using one of the repraps if I can't.

Re: Up mini printquality
Good day! I try printing boxes with many thickness (step 0,1mm) and you can see my results:
If you need my test file, i can put him in file hosting.
Thanx, good bye!!!
Walls with tickness 1,0-1,3mm is good! Tickness 0,5-0,7 is not printable... Hmmmm... Nozzle 0,4mm!!!If you need my test file, i can put him in file hosting.
Thanx, good bye!!!

Re: Up mini printquality
As another experiment for yourself turn your print 45 degrees. You will see your results are different. They will change again as you change the layer heights for the prints.

Re: Up mini printquality
Rotated on 45 deg. and best thickness of walls is 1,0-1,3mm again.

I took this snap of print, with 2.5mm wall, @ 0.25mm layer height, latest software... I am pretty happy with 2.5mm wall result, but it does look different to your 2.5mm...what layer height you using??

Re: Up mini printquality
given that when I make a box the press fit lid, fits different if i use different layer heights, then the bigger layer height has more flow and more smoosh maybe, anyway it lays a bit thicker across the gap, and thats why mine looks different...

Re: Up mini printquality
I new to this world so I'm not sure whether this is valid advice, but I emailed to support@3dprintingsystems.com and got the response to rotate the model only 10 degrees to correct the double-wall problem.

Re: Up mini printquality
Good day!!!
ktronik, Im use 0.20mm height layer and latest software too, but a will try you settings and post a results.
ajohnsonlaird, I will have to try this option.
