Building the C-Bot 3D printer: Part 26 : First ‘big’ print

I’m still heavily tuning the extrusion, but wanted to print something ‘big’ to see what the machine could do:  Ran across the ‘Zuzanna Lamp‘ on Thingiverse, thought I’d give it a shot, it’s about 10″ across:

Print settings were:

  • 1.0 Volcano nozzle, 500 micron layer height.
  • Extruded @ 200 deg, HPB @ 60 deg.
  • ‘Natural’ PLA.
  • Took about 6.5 hours @ 30mm/sec.

Things learned:

  • Still having a hard time getting each layer to stick together:  Many horizontal cracks showed up during printing, where the layers were delaminating.
  • The print quality towards the top really fell-off : The filament would really ‘wick up’ at the end of an extrusion.  I feel its not being cooled fast enough.

So a lot more tuning is needed, but hey, at least it printed something bigger than my Replicator 1 ever could! :)
