Two Voronoi cats

(10/28/2016)

I used Meshmixer to add manual support. The Voronoi cat model took two hours and thirty minutes. laser-cat-sc1

Slic3r 1.2.9 to generate a gcode file without support.laser-cat-slic3r-sc1

Filament: eSun PLA+ 1.75 mm
Temperaure: 185 C
Printing speed: 25 mm/s (Perimeters)

I pushed Steel Fisher to extreme how it would handle a long printing hours that has heavy retraction. The total printing hours was about 33 that kept me awake for two straight nights.

3D Model: LASER CAT – Voronoi Style

Size: 103.09 x 112.91 x 167.1220161022_0761

The first attempt failed, which wasted 1h 38m 55s.

The big troublesome question was “How to prevent the nozzle dislocation middle of printing?” And I had been fixated to default Lift Z height in slicer programs that set for Cartesian 3D Printers, which ranges from 0.025 mm to 0.4 mm.

Two days ago I thought ‘Hmm, what if the nozzle goes up and down so high that there is no chance to hit any plastic part? Then it would eliminate the nozzle dislocation, potential print failure.’

Two millimeter was little low, so I set three millimeter as Lift Z height in retraction. Slic3r 1.2.9 hang in the voronoi cat’s gcode generation with support. I used KISSlicer to generate a gcode file of the Voronoi cat with support.

I started to take photo with one minute interval.

It finished the printing at 32h 58m 43s.

The weight of voronoi cat was 55.3 g.

Steel Fisher has outperformed my expectation.
