Topic: how do you print extra supports?

Ok, I have another thread going about an object I am having difficulty printing, but I dont want to add another question


Basically, I am tring to print a little mini alien, the print seems to start ok, but over time unglues.


I read somewhere you can tell it to print "extra support"

I am using "Repetier host" and for the life of me, I cant seem to find any option that makes the print have extra support to stick the feet better to the bed.

is there something that I can give my alien "bigger feet" so he sticks better to the table?

You're looking for brim, not support.

Something else to try is to slow down the print speed on the first later (slic3r has a setting for this).  Try 50% slower.

Ok, so I have the flu and it was a rough night, so I am  only just getting to this now.

- I will play with the speed for sure!
- I just kicked off a PLA run, I tried one last night, but it said it was a 2hr run, and needed sleep!!! so more to come on this one.

- as for this "BRIM" how does one add those? enable? configure?

please and thanks.

If anything, I will say the community has been awesome.


I will be happy once the ABS is printing!!!

Hi Menglor, you can set the brim setting from within RH just go to the 'slicer' tab on the right side of the screen then the 'configure' button for the slicer that will open up a new window from there under the 'print settings' tab go down to the 'Skirt and brim' options, in that window at the bottom is the brim setting just type in a number like 3 or 5... if it still does not hold enough up the number a bit more and also like 3doodler said slow the first layer down... this can be done from the option 'speed' right above the 'skirt and brim' selection. Hope this helps smile

Re: how do you print extra supports?

you might want to try a different model as well.The one you're trying might have issues that are unrelated to your printer. I was surprised by the number of things on Thingiverse that have problems. I automatically run anything I download from them through Netfab now. Even things that a bunch of other people seem to be able to print without any problems have given me trouble. One that comes to mind, the Paste Pusher Animals, was recommended by someone as a good beginner print. I was a beginner at the time so I downloaded the three of them and tried to print. I ended up with all kinds of strange results. I tried adjusting my slicer settings and printing the different animals, still no go. Now on the download page plenty of others had said how cute they were and had prints that they'd done. I'm thinking "what am I doing wrong". I had heard about the Netfab online processing  and uploaded them. I got a message back apologizing stating the model was unrepairable. Lesson learned. I don't know if this could be the part of the problem your experiencing, but you never know. I've run into a few models with multiple parts in the STL file that aren't on the same plane, one or two parts will start printing three or four layers after the first part starts. It's not a perfect world, but there are plenty of cool things out there to print...

Good luck.

Re: how do you print extra supports?

I will be trying other models, however, its mostly printed  when I did it with PLA. so I know the model is fine.


its printing now with a 3mm Brim, which frustratingly enough, has also curled up.

the Bed temp is at 105 , I am not sure what the max is. but I am going to have to play there too it seems.

Re: how do you print extra supports?

Drop your bed temp. It will cause your bed to be a more even tempreature - raising it will cause it to have hot-spots all over the shop with huge deltas between temps - that is what causes curling more than anything else.

You need to wipe the bed down, make sure there is no contaminants at all on the surface (fingers leave oil, and the oil is the worst for making stuff unstick), heat the bed to 90-95°C and then let it soak for a 10 minute period so the whole bed is even temped, and then print with a squished z-layer.

But just cranking up the bed temp - Its not the panacea that is often asserted. It will invariably make your situation worse.
