First, I'll share my results so you know what I mean when I say this turned out pretty bad.
Final Results
Glamour shot, if you will |
So this is a pretty good picture simply because you can see most of the flaws right up front. Weird splotches and holes in the layers of resin, blobs around the eyes and mouth that weren't supposed to be there, a nice big dent in the forehead section, and some warping around the bottom. I know what caused everything except that dent-- seriously, the heck happened there?-- and will outline which step caused what below.
Step Two: Molding
Creating a glove mold for this mask seemed like an easy enough thing to do, but many of the surface flaws came from me not knowing what I was doing. I used Smooth-On's Dragon Skin rubber, brushing on a few layers over the course of a couple days. This was a good choice of materials, but I skipped a very crucial step-- adding a thickening agent to the last couple layers to beef it up. This is especially important to do on something like this mask, which has some really pointy high-points and corners. My mold ended up ripping around the eyes, mouth, and nose areas when I went to demold, which caused those weird surface anomalies. It also made a huge mess in my mother mold.
Of course, the mother mold had its own problems outside of some spills. I tried to go the cheap route and use plaster bandages for this hard outer shell. Pro tip-- don't try to use plaster bandages. They were not nearly sturdy enough for this job and my mother mold ended up too floppy and soft in places that needed to be rock-hard, like the entire jaw. That might actually be where the dent in the forehead came from, now that I think about it. As a bonus, the powder from the bandages goes everywhere and there seems to be nothing you can do to stop this. I will most likely look for another Smooth-On product next time I make a mother mold, as I think they have a paste meant for this purpose.
The other problem I had was that the rubber kept flopping around inside the mother mold any time I tried to rotate the whole thing, which is definitely not ideal considering the mother is meant to hold everything in place. I ended up fixing this by taping everything to a piece of cardboard, but it wasn't elegant in the slightest. I believe the proper method is to bolt everything to a piece of plywood when you have an open-face mold like this, but I'm still looking into it. It might just be a matter of making things properly from the start.
Step Three: Casting
The casting process had its own challenges, the main one being that I was very timid with the slushing part because I knew there was a good chance my mold would leak or spill since it was so poorly-built. You can see this in the picture as the spots that ended up grey instead of red-- that's where a layer didn't quite cover the entire surface of the mold. Getting the jaw and chin area covered was especially difficult, since it was prime "spill it all over myself if I do it wrong" area. They ended up very flimsy as a result.
Because of this lack of coverage, I ended up doing too many layers of the red resin. This was a clear-cast resin I had tinted with the intent of leaving a glass-like layer on top of the dark grey base. In some spots this kind of worked, but overall the effect didn't come through like I had intended. I think if I try this again, I'll paint the first layer onto the mold instead of casting it so I can control it a little better. I'm not sure if XTC-3D would work for this purpose, but it might be worth trying.
Step Four: Sanding and Weathering
This step worked out about like I planned, so I'll just touch on it briefly. After the cast had finished hardening, I wet-sanded it starting at 400 grit all the way up to 1500 grit or so. This wouldn't have been necessary if my original had been nice and smooth, mind you. I'll give it another sanding session before I attempt another mold so I can skip this post-processing on the pulls.
Once it dried, I mixed some black acrylic paint with water and just slopped it into the seams and scratches of the mask and wiped up with excess with a paper towel. I could have done a better job of this, but I think it turned out kinda nice considering how much of a mess the rest of the mask was.
More Pictures
Here's the rest of the pictures I took before sending this mask off as a Christmas present. I've also compiled them into an Imgur album if that's less painful to view. Hopefully this summary of my comedy of errors saves someone from making the same mistakes!
