Maybe because it's fake?

The bed doesn't move on that machine, so it is very possible.
That is tpu, which has excellent bed adhesion. |

I don't really see any area, aside from maybe the tip of the toe box, that would need support (in that orientation).
Have you ever seen the pin support challenge? |

People dont realize how unnecessary supports are in most situations.
I VERY rarely use supports. I basically never use a brim. If you have Z height set properly you get pretty good bed adhesion. That allows for some decent overhangs and decent ability to eliminate supports. Not particularly impressive once you understand what is capable with proper settings and hardware. |

ETA - I'm goign to try no supports on our next print - we have a slight overhang, a channel, and a few holes we push hex nuts into. Not having to clean up support would be amazing. |

Quote HistoryOriginally Posted By stewie97: How do you print holes with no supports? Depends on hole shape, size, and part orientation. For example, printing a square shaped hole, if the part is oriented so the hole has the top and bottom edges parallel to the build plate, then the nozzle would make a long pass over nothing to do the top edge of the hole, and there would be a high likelihood of failure without support. But, if you could rotate the part a bit on the build plate, and have the square now be at a bit of an angle, then there is no flat unsupported top side, and instead the angled edges can be built up slowly until meeting at a corner. That's why in the OP video, the shoe is oriented at that 45-ish degree angle. It allowed a slow ramp-up of all the sides and no flat overhangs to worry about. |

I have a couple that are parallel to the build plate, so that wont work. the cumbersome ones are horizontal to the build plate, so I'll try it on those |

not sure if serious op?
those overhangs are real reasonable. if bed adhesion is good, its all good. |

So we can print shoes now. The world is quickly becoming amazing.

Would be interesting to try to use a bl touch or some other touch probe to make a point mesh from a silicone rubber mold of your foot. |

Yano I never though about putting a finder on a 3D printer to use it to probe an object to generate a file....I'm sure there's some code out there for it somewhere. I've got a spare board with a dead extruder stepper I could use that for... |

Trying no support currently. |
