I have Zero experience with 3D printers. I have been considering buying a 3d printer to print a right hand prosthetic. The thing is, on my right hand, I have the first phalange up to my knuckles on all my fingers. Would it be possible to modify this print to use as a "Glove" over parts of the fingers I have? I would love if someone could help me out. Thank you
Question, is something other than 100% infill acceptable? I use 40% for very strong parts, is 100% for PLA? I print in PETG which is much stronger, can I use like 20-40% of S3D hexagon infill (full not quick hexagons)?
My apologies for the late response. You can use what every type of infill structure or percentage of infill that you would like. I found that material choice and printer quality were the leading factors in the parts strength, not so much the infill percentage or structures. The weak points are pretty thin so the infill is not as important. I have not used PETG that much so I don't want to offer advice on something I am not that familiar with. Best of luck with the printing!
Hi Evan, this video, I believe, is not the most updated version of the k-1 hand, is there another video with an updated version? If not, could you give me the version that you used in this video?
Hey Tarun, This video was the only video created by 3Dsystems for the K-1 assembly. This link to their web page can be found here below. You can download the files that match the video from that site as well. prod.cubify.com/store/3diy/enablehand
Hi Evan - Reading the K1 paperwork it mentions 100% infill density and diamond pattern? Is 100% solid still the case after multiple builds? I'm working on my test print for Enable Community Foundation and wanted to confirm as I move forward. Thanks!
Hello, Sorry for the delayed response. 100% solid is still suggested, however depending on the specific printer and infill patter I know you can get away with less. It also depends on the use cases, if your printing if as a class project, then I would advise less infill to save material, but if you think your applications will require a more robust print 100% is probably the way to go. I do know I was getting away with 50% infill just fine but I was using a nylon filament during that testing. best of luck, Evan Kuester
Hi Evan - Where can I find the forearm piece with additional holes for the knots along the backside of the wrist? That link includes a flat forearm and makes the final tie-ups a challenge (unless the model has since changed). The model included also has less slots for the velcro straps... am I missing something? Thanks for the advice!
When you say flat forearm I am slightly confused. The forearm for the K-1 is curved. Currently the only file that is available for download is the one you may have already downloaded. prod.cubify.com/store/3diy/enablehand But I do have a version with no holes in it that your welcome to punch as many holes in as you like. If this is acceptable I can email you the file.
I designed the palm to be printed standing up on the wrist as shown in this link. imgur.com/CiamzxI I've never seen it printed in any other orientation. However if the stability of the part is the issue. Consider adding some extra supports along the bottom edges of the palm for extra stability. imgur.com/ioWrF8K
Evan Kuester Yeah, i was looking into that as well. Though I think it may be an orientation issue as well since there is a "stub" that sticks out next to the extruder that is used for calibrated the print bed. That stub is probably what's messing things up.
There is a possibility that the fingers may not print well in any other orientation than in the one in the download. I designed them to print without the need for supports, but because of that they only print well in one orientation.
Hey Michael, Normally I import a photo of the hand into what ever software I am going to use to do the scaling. In my case that's normally Rhino3D. In the photo I place an object for scale. Like a ruler or a dollar. Just to make sure the photo imported the right size. Once I'm sure the scale is correct. I scale the parts to fit the the hand in the photo. Normally scaling slightly larger so that its not to tight. I have a hand that assembled digitally so that its easier to scale if you would like me to post it.
evan is it possible to make this out of titanium with more heavy duty components like high tension strings and leather straps for example. looks good but not very sturdy.
This particular model wouldn't print well in Ti or other metals. Some of the over hangs and axles have not been optimized for metal printing and could fuse shut or crash the build. However if you are interested in printing one in metal I would be happy to help with the modifications.
Starting to print one tonight. PETG at .2mm and .15mm for various parts. Hope it comes out nice enough for donation to Enable

The link of the print files is corrupt or not working

а вы учите людей как работать с 3д моделированием?, мне себе тоже хочется смоделировать протез руки
I'm having troubles determining the better orientation for the palm to be printed. Suggestions? Currently using a XYZ DaVinci 1.0A 3D printer.
I designed the palm to be printed standing up on the wrist as shown in this link.

What did you mean on the note:
Print-in-place joints must be printed pointing upward.
What slicer program did you use? Wondering if that's affecting my prints as well.

Hello,
I am in the process of printing one for a recipient. What is the best way to determine the proper scaling factor?

Hi Evan,
Thank you for your reply and information. Are you able to post the hand that is assembled digitally?
Can I print this in PLA with the same results? I will be using makerbots too. My Engineering class would love to build these
You can print it with PLA. I've personally printed this design with ABS, PLA, PET, and Nylon with varying results.
