Iron Man mkIII 3D Printed

I think my scaling is getting messed up.

This is supposed to be the bottom of the thumb, and the middle joint of the middle finger.
 
I would say so... are you running through netfabb? Doing the convert from inches to mm thing??

Well, first I opened your hand file in Blender. I deleted everything but the fingers, and saved it.

I've been exporting each one as an .obj, but Makerware says they are unreadable. I opened them in Mesh mixer, and exported them as .thing files, which Makerware seems to like.

I was pretty sure I scaled the fingers in Blender to be the same scale as the hand I already printed (110mm wide hand).

The scaling didn't work though, because when I open them in Makerware, they are a fraction of a millimeter wide, and a prompt pops up that says "This object seems very small. It may have been designed in inches. Would you like to scale it to millimeters?"

If I say yes, then it gets a little bigger, but it's still less than a millimeter wide.

So what I have been doing to try to get it the right size is checking what the X dimension is in Blender, and scaling the X dimension to that in Makerware.

Apparently is doesn't work, though.

Run them through netfabb and export them as stl's.
 
What primer do you use?

Using this to fill over spot putty:

...and the cheap stuff as a final smooth coat.

Are you saying the resin self degasses or the silicone you used?

If it's the resin you meant, well, that looks like what I've been lookin' for!!!

Yeah, the clear is self degassing. On the palm repulsors, all of the bubbles were to the top withing 20 minutes.... gone within 2 hours.
 
the same primer company you use also sells a primer filler sandable version is there a difference between the two really???
 
Ok, here are a few pics. I never think I'm making much progress until I look at my last round of photos. So I guess I am making some head way.

Also in the first stages of designing the skeleton for display. I want it to be slightly poseable... not action figure poseable.
I'm thinking about the pivots being part of the skeleton, this way the armor can just kinda sit on the supports without much fastening. This will also allow me to go back and add/fix lighting or animate panels without too much trouble.

that sounds like the right way to go, build into the suit what you can. it is ironman, its a"functionalist" suit
 
First mold of the Unibeam was pretty crappy. The part had some wicked undercuts and the micro mesh in the center had all kinds of bubbles. I ended up filling the undercuts with clay and brushing on the first layer of silicone, making sure to get it in every nook and cranny. I'm very pleased with the results.

Time to cast some clear Unibeams!
