Makergear M2: MAKE Magazine Torture Test

Posted by Ed in Machine Shop on 2013-04-17

This was the second object I printed, immediately after getting that good thinwall box:

MAKE test object - arch anchor fail

The arch foot broke loose from the platform after it grew to about 8 mm, but that seems to happen with most of the DIY printers. Apart from the tangle produced by that flaw, the rest of the object came out essentially perfect:

The surface finish is rougher than I think it should be, but the dense zigzag infill on the two thicker solid walls of the box seems to disturb their outer finish; the two thinner walls have linear fill and are fine.

The slic3r header:

; perimeters = 1
; top_solid_layers = 3
; bottom_solid_layers = 3
; fill_density = 0.20
; perimeter_speed = 100
; infill_speed = 150
; travel_speed = 500
; scale = 1
; nozzle_diameter = 0.35
; filament_diameter = 1.70
; extrusion_multiplier = 0.9
; perimeters extrusion width = 0.40mm
; infill extrusion width = 0.40mm
; first layer extrusion width = 0.39mm

There’s no source code, as I used the original STL from Thingiverse.
