My latest head scan print.



  • I got a pretty good scan done of my brother. It turned out quite well, though the texture of the skin might be a bit exaggerated compared to reality, it is a great test of the detail possible with FDM.

    PLA, 80 micron layers, 0.4 mm nozzle. Printer is slow, and jerk is set low (480mm/min) so the print time will be 3-4 days.

    PS I am very sorry, but I cheated… this was done with a Duet 0.8.5 (haven't got a wifi yet to try). Please forgive me.



  • The print just completed. 94 hours total! Wowza!

    Amazingly, even though this model has a ridiculous mesh density, this was in the m122 after:

    Move Diagnostics:
    MaxReps: 7, StepErrors: 0\. Underruns: 58
    
    

    Amazing. You've done some great improvements to the motion code lately it seems, dc42. Thank you. I'm running 1.15-beta3 (2016-07-09).

  • Very, very cool.

    Out of curiosity, is this done with the "vase" spiral mode, or are there more than one perimeters per layer?

    If it's not a spiral, how did you deal with the seams? Are they running up the back of his head? 🙂

    And what slicer program did you use?



  • Thanks. It was not done with spiral vase mode. There are 3 perimeters, and no infill other than selective solid infill simplify3d puts to maintain shell thickness.

    Yes, the seam is running up the back. It's pretty small but still visible. I actually sculpted the back and top of his head smooth to help alleviate some suspected problems with the rough hair, so the back is kinda funny looking.



  • Thanks for the info. Now that I have my printer mostly dialed in, I'm looking into slicers and slicing parameters. I was curious how you did it.
    Cheers!



  • Nice job. How did you get the scan?



  • Thanks. It was professionally done by a company called Pixel Light Effects. I got a second one done, too, and printed some 1/6th scale heads as a test: http://imgur.com/a/kwwDL



  • That is amazing! The skin is is so detailed! And I can barely notice the print lines!



  • Thanks! It is pretty good, but I'm almost ready to build a printer that should produce even better results… all made possible by Duet.

    As a side note, this head print was one of my longest prints until just the other day -- 204 hours print time is now my new record (client's print, can't show pics unfortunately.)

    Not a single ajax disconnect in those 204 hours! (Duet 0.8.5 on an ancient beta firmware 1.15) (Sorry for any users encountering troubles, not meant as a low blow.)

    Wow! That's like 8 and a half days - hope you charged the client a lot of money. 🙂



  • It was only part of an order, but that part alone was priced at about $650.



  • Cool, if your brother get an iPhone X you can probably unlock it 🙂
