Trying to print a mini dome/cupola fails at the end

Recommended Posts

Hi, I'm trying to print something like this: Unbenannt.thumb.jpg.e6a0d561f7016202f6fcfb60c9339f84.jpg

which should be a plate of about 1.5cm on the sides and the cupola is 8mm in diameters and 0.5mm thickness.

The print starts fine but when the UM² tries to close the dome it fails somehow:

Any ideas on what I'm doing wrong?

Or am I hitting here any limitations because of the thin walls? But that would be the case if the dome would fall inside no? It seems somehow as if the UM2 is pushing to much material at the end.

It's getting overheated as its so small.

Try to print it at 30mm/s and 190 - 195deg (PLA)

Print 2 of them at the same time or make a pillar to sit next to it. place the second item to the side so the fan will blow on your item while printing the second one. This will allow heaps of cooling so it wont over heat.

Adding support will help as the very top will end up ugly on the inside otherwise. you can change the angle so you only have a small amount in the very center so it will be easy to break off.

you can also print something like THIS to help add heaps more cooling.
