I never actually ended up using it. I took a little break on the project, then I realized that mold wouldn't be a very good test of how the actual mold will be set up, and would be a waste of a lot of silicone. So I'm doing another small test, but with an SLA resin mold this time and a TPU core...

Minor update: I printed a mold of the ear as a single piece, to see if it's possible to demold it without damaging the pull. I'm gonna do that and the antenna test at the same time, so that's next on the printer. I'll be ordering the silc pig and a couple other things this Tuesday in case...

It really resembles an Israeli helmet, but with a lip on the front. Could also be an Italian helmet.

Yeah, you can definitely see the print lines in the silicone even though it doesn't come through in the video. It's pretty weird to see that 3D printed surface on something that wasn't printed. I'll try doing another test print of the antenna next like you said. Do you think I'll need a lot of...

The test actually went really smoothly. There was no issue with mechanical lock despite the print lines. What do you guys think about the material choice? Does it look like it would be good for the whole mask?

You convinced me I should definitely start with smaller scale tests rather than jumping right into the full mold and possibly wasting a bunch of money. I printed a little box mold in PLA since the surface finish won't matter for this test (except for the potential for a mechanical lock I...

It's gonna be wearable, but a bit different from other silicone masks in that the mask's movement isn't coming directly from my facial movements, but from a servo or some other mechanism since it won't be skin-tight all the way around my head. I was also planning to cut a slit in the back to...

I'm going to be printing it on my Peopoly Phenom L printer with Siraya Tech Blu. I'm also going to try heating the vat with a fermentation belt since Blu needs a higher printing temperature to get the best results. I've never printed anything as big as these pieces, so I'm a little nervous about...

Thanks for all the advice! I was waiting on some cured samples Smooth-On said they'd mail to me two weeks ago, but they never arrived. I think I'm going to buy a couple sample kits of Dragon Skin 20 since I found it on Amazon with free shipping. Two sample kits should be a bit more silicone than...

I think you're right about mounting the cables to some kind of harness. I wonder if using a stiffer silicone would be adequate. Anyway, I finally made progress with the mold design:

Thank you for all the excellent advice! I was actually thinking the best way to achieve the motion might be to have a servo and controller hidden on my back somewhere and a cable or two running up the back of the mask. Like you said, I need to think it through and try things out. I'll keep this...

Sort of. It's been a lot of work with booleans trying to get clean geometry for the mold, but I'm getting there. I think it's just a matter of figuring out the best software for the workflow. If it doesn't work out, I'm gonna have to mold and cast the old fashioned way. I'll post an update once...

Thanks for the idea! Do you mean something like this? By the way, I learned Zbrush from Michael Pavlovich's YouTube videos. If you want to learn Zbrush starting from nothing, I don't think there's a better teacher.

(Screenshots in Unreal Engine 5) I've never attempted to make a silicone mask before, but my love of Greedo has forced me into this project. Right now I have a zbrush sculpt that I'm more or less happy with, and I can 3D print this sculpt at 1:1 (although I might have to do it in pieces)...

Amazing detail. Laser cut or just a lot of work?
