Supports always fail | 3D Printing | Page 1

My supports always fail, same goes for small tiny towers, i am just so loss and have absolutely no idea why it does this. Im following the settings on the filament label and i have it set to 190 degrees temperature and 145mm/s printing speed. The adhesion on the bed is never the issue. Could it be that the support lines are too tiny for the heat maybe? 😭

AI Help

It sounds like your supports are not strong enough to maintain their structure during printing. This can result from insufficient adhesion between layers or poor layer adhesion due to improper settings. Here are some troubleshooting steps to consider:

Increase the support density in your slicing software to provide more material for each support structure.
Increase the support line width to make them sturdier and less prone to breaking.
Consider adjusting your print temperature upwards slightly to improve layer adhesion.
Check your print speed settings to ensure they are not too fast for the material you are using, as high speeds can lead to weaker supports.

Try these adjustments and see if they improve the strength and reliability of your supports.

Im using a creality ender 3 v3 SE

And the software is ultimaker cura

#

this one specifically

#

oh! and my support overhang is on 30 degrees!

#

#

it would do the same at 45

#

so i thought maybe the angle was the issue yk?

fluid pewter Sep 9, 2025, 3:07 PM

#

Hmmm could be an issue with the print speed

hardy ivy Sep 9, 2025, 3:07 PM

#

145 is too fast!?

fluid pewter Sep 9, 2025, 3:07 PM

#

Possibly

hardy ivy Sep 9, 2025, 3:07 PM

#

speed pla my ahh

#

my printer could print supports just fine back then

#

at 200 mm/s

#

back then i had the cheap filament instead

#

is it possible that it just burns the supports mid print?

fluid pewter Sep 9, 2025, 3:09 PM

#

Im not actually sure tbh

#

Never really seen an issue like this before

hardy ivy Sep 9, 2025, 3:09 PM

#

fr??

#

oh no 😭

fluid pewter Sep 9, 2025, 3:10 PM

#

Everything seems to be printing fine apart from the supports

hardy ivy Sep 9, 2025, 3:10 PM

#

not just the supports

#

whenever i print 2x2 wide towers it fails

#

and prints weirdly

#

small ones especially

fluid pewter Sep 9, 2025, 3:11 PM

#

Filament could probably be wet then maybe

hardy ivy Sep 9, 2025, 3:11 PM

#

2mm i meant

#

hmm

#

wet

#

darn i dont have a dryer thingy

#

Can i try 180 degrees?

fluid pewter Sep 9, 2025, 3:12 PM

#

hardy ivy darn i dont have a dryer thingy

You can just put it on your heated bed and cover it with a box

fluid pewter Sep 9, 2025, 3:12 PM

#

hardy ivy Can i try 180 degrees?

You can try it but i dont think its a temp issue as 190 is recommended for pla

hardy ivy Sep 9, 2025, 3:13 PM

#

yikes

#

ok the print is done

#

let me show you in full detail of the supports

fluid pewter Sep 9, 2025, 3:14 PM

#

Ok

hardy ivy Sep 9, 2025, 3:14 PM

fluid pewter Sep 9, 2025, 3:15 PM

#

That is really weird

hardy ivy Sep 9, 2025, 3:15 PM

#

ikr? 😭

#

hurts to watch it happen

#

see what i mean by melting?

fluid pewter Sep 9, 2025, 3:16 PM

#

What nozzle size are you using

hardy ivy Sep 9, 2025, 3:16 PM

#

0.4

#

i can double check one second

#

its 0.4 yeah

fluid pewter Sep 9, 2025, 3:17 PM

#

Might be an issue with your z offset then

#

Looks like its too high

hardy ivy Sep 9, 2025, 3:17 PM

#

please tell me thats something i have to change in ultimaker cura 😭

#

on the printer itself the z offset is rather tight

fluid pewter Sep 9, 2025, 3:22 PM

#

hardy ivy on the printer itself the z offset is rather tight

You have to do that yourself

#

By moving the z axis or down

hardy ivy Sep 9, 2025, 3:23 PM

#

but its really tight though?

#

idk if it can go any lower

fluid pewter Sep 9, 2025, 3:26 PM

#

Are you doing the paper test?

hardy ivy Sep 9, 2025, 3:29 PM

#

yes and then i do it mid print so its adhesion is strong

#

I wish i had that old filament to test it out

#

the nozzle also is always dirty after the print is finished i forgot to mention that

#

i have to constantly clean it

#

it seriously feels like its a temperature issue since its leaking so much

#

so when its printing the supports it just leaks halway through and causes mayhem you feel me?

#

or maybe im wrong

#

but i can try it out at lower degrees

fluid pewter Sep 9, 2025, 3:35 PM

#

I have no idea what is going on then

hardy ivy Sep 9, 2025, 3:35 PM

#

ender 3 are evolving dude

#

they are creating new issues each day

#

they have a mind of their own

#

I will design a small 2mm tower and then do the test :)

#

first i have to eat sorry

hardy ivy Sep 9, 2025, 4:15 PM

#

update on the print

#

185 seemed to do a fine job

#

but uhh yeah idk
