Ah well... not really glass... not real diamonds, but it has a diamond look... sort of Swarovski-style...
More or less by accident, but i am surprised how good you can control the irregularity so it gets regular again.
This is only the very first test...
Print with very very high extruder speed and with a big [0.8mm] nozzle.
in sf46 the most important settings are:
layer thickness: 1.1mm
w/h ratio: 2.1
feed rate: 45
flow rate: 1250 [ in reality 2x, i did put my stepper driver not on micro stepping, but less steps a round, so it moves twice as fast as 'normal']
the extruder wheel is really spinning like crazy...!
temp: 240 deg
- material is PLA
- higher temp for more liquid PLA [be careful if your nozzle holder is not PEEK]
- flow/feedrate depends also on your firmware i think in sf<40 i did 'normal' 0.8mm prints with more or less flowrate = 1.5*feedrate, with my first experiments with sf>40 i got very high values, maybe because my firmware still thinks it is using sf<40 [i am not so good in software...]
- microstepping off, only for extruder, that is the one who needs high speed [on the ultimaker due to gears]
- 0.8 nozzle was original nozzle drilled with 0.8mm drill, but also an ordinary closed bold [?!] could work
- z-adjustments by hand did the control between smooth and irregular, higher z, more irregularity.
