This is the C7 logo I created in school using our IDEAS program. The XYZWare sliced the checkered portion out in that empty indent on the left side. There usually is a 1/16" extruded effect in there to make the checkered look. This was printed out on my Da Vinci 1.0 and pre calibration. I have now re-calibrated the printer and I'll print out a better example and post the picture afterwards. Enjoy!I believe the white one is printed in .2 or .3 mm layers with a horribly calibrated printer. Since then I have recalibrated and printed in .1 to make a really great result which is the black one. The red logo is the one printed out at school with their MakerBot Z18 at .1 mm using PLA whereas my prints are ABS. The density can be anything you want.
