The MakerBot Digitizer 3D-scanned Laser Cat model was used in this test of different layer thicknesses. The cat was scaled down to 50 mm in height and then 3D printed at the following layer heights: - 0.40 mm (400 microns) - 0.30 mm (300 microns) - 0.20 mm (200 microns) - 0.10 mm (100 microns) - Average width of a strand of human hair- 0.05 mm (50 microns) - 0.02 mm (20 microns) All six cats where 3D printed on a MakerBot Replicator 2 with TRUE BLUE PLA plastic at 230 degrees C. All layers where 3D printed with MakerWare's standard values as follows: (400 microns) - 15% infill - perimeters 2 - speed 90 mm/s (300 microns) - 15% infill - perimeters 2 - speed 90 mm/s (200 microns) - 15% infill - perimeters 2 - speed 90 mm/s (100 microns) - 15% infill - perimeters 2 - speed 90 mm/s (50 microns) - 15% infill - perimeters 2 - speed 60 mm/s (20 microns) - 15% infill - perimeters 2 - speed 40 mm/s http://youtu.be/2QGJdRVxtsE http://youtu.be/JLSvLMD0RmU
