Hollies hand full colour print

thingiverse

UPDATE 19th September 2015: Hollie puts on the hand and is extremely pleased with it. The socket requires more cushioning and tightening, but her father will take care of that once they get home. They also informed me she was using the previous model quite extensively, and getting more out of it as her arm became stronger. So my next approach will be to combine the previous all nylon printed hand with covers of the full colour printed hand. UPDATE 18th September 2015: Due to conflicting holiday and work schedules, Hollie hasn't been able to try out the hand yet. Hopefully this will change tomorrow. I've uploaded some images of the hand coated in silicone with the nylon printed prosthetic cup. My wife thought loom bands would look good, and since it's for an 8-year-old girl, I agreed. ORIGINAL: The print of Hollies hand has arrived from Shapeways. It is printed in full color sandstone. I did print one finger in full color plastic but it didn't come out very well. I'm currently adding a protective layer of silicone to it. The sandstone is quite brittle and grainy, so the silicone will help keep it together. I'll add a layer of epoxy to the inside to help reinforce it. It's possible to infiltrate the hand once it's printed with epoxy, but since I had to outsource printing that's something I couldn't control. I plan on doing a similar thing with the hand once I've finished the Anthromod V2.0 parametric hand. Here the hand will be broken into sections and placed around the Anthromod 'bones'. If you want to help me develop this hand, you can donate to http://www.gofundme.com/prosthetic-hand. It really does help cover the costs of getting the parts printed. I will add additional updates as I process the hand and eventually Hollie tries it on.
