Activity – Bob

Bob posted an update a month ago

Hi gang…it’s been several years since I was active…I am starting over printing my InMoov robot. First one was started with ABS and I had a lot of problems with parts not fitting correctly. Also was learning how to use a 3D printer. Fast forward, I now see that there is a version 2 or i2Hand that was developed…I’m guessing that some of the issues have been upgraded and enhanced. Before starting, I am now going to print using PETG filament…I’m guessing others have used this type of filament. From what I have researched, it does not shrink like ABS and I should have a better experience getting parts to fit. Is that what everyone’s experience is like?
I also bought a bigger bed 3D printer (Creality Ender 3 v3 plus) which was also a challenge from the older one I had…
Any comments about the new hand design are welcome as I’m trying to get caught up on some of the new changes to consider.

  Hi Bob, Nice you want to start over again. I bought a Prusa Mk4s 3D printer especailly for this challenging project. Also in a newbie learning stage. I’m printing with PETG filament from Prusa and I’m very satisfied with the results until now (just printed the fingers, handcovers, wrist). Mostly I follow Gaels instructions about the infill, wall thickness, etc. For parts to fit, you have to use the calibrator and Gael advice to set the horizontal slicer (I google that and find out that it was the x-y slicer) -0.15 and play with it until you find the right fit. With Prusa Mk4s that’s -0,10. The only problem I face is the overflow of support material that stuck in holes. I tried to make the support more “loose” not closly attached to the model, but some times I still have to reprint parts by changing the angle of the model for clear holes. It’s a slow process with a lot of new things to learn, but it’s also extremely sastisfying when you see your project grows. I’m sorry for my bad grade English.
  
  Enjoy your project,
  Marina
