As you may know, for my big Christmas project, I need a singing character.
Having recently purchased an Ultimaker Original 3D printer, I thought that this machine was perfect for creating this character.
After finding a singing tree that suited my needs, I started printing it. And that's when the struggles began.
First, the adhesion problems. The parts were coming off the bed. But after a little recalibration, everything was back to normal.
Everything? No! One problem still persisted: the filament was getting crushed in the extruder, which blocked the print.
After several hours of testing, I understood that the extruder clamping screw was simply not tightened, which crushed the filament at the slightest resistance.
Everything was finally going perfectly. The tree was progressing very quickly. Until the filament crashed.
Not really being alerted by the problem, I tried to simply remove it (as always when this happens), but nothing doing.
All I managed to do was break it and realize that it was indeed blocked.
Having tried everything, I then made the decision (which turned out to be one of the worst possible ideas) to cut the pipe connecting the extruder to the print head in order to unjam this filament.
Without success. I finally managed to remove the stuck filament by disassembling the head.
Once the latter was reassembled, I patched up the cut pipe with electrician's tape and "Colson" clamps. I started a print and...
...my repair did not hold. The pipe comes off when cut with the pressure of the filament.
I try to add adhesive. It doesn't hold. To print a part supposed to hold the two ends of the pipe. It doesn't hold. To glue this part in all possible ways. It doesn't hold.
Cutting this pipe is really one of the worst ideas of my life. If you have solutions to mend this pipe, let me know in comments or at linaki@linaki.org.
I plan to order a new one, but it could take a month to arrive, and I need these parts very quickly.
See you soon for new adventures.
