so allot of this you'll have seen before, but figured I'd document it out anyway.
starting with the mold, it doesn't look that neat and tidy, and it's one of the more complex ones I've made so far...and I think the finished cast is quite nice for a "grate-ey" floor tile. I've started using a mold release caoting after each cast, and I find that even complex peices like this, pop uout super easy....well worth the $4.95 IMO
quick drybrush with gunmetal metal (vallejo version of botlgun metal) once again, my pic taking is haunting me, as it looks way less silvery in RL....but there we have it, a molded/cast tile for the space hulk project, from start to finish...only eleventy thousand more to go!
I may experiment with other paint schemes and or methods of painting....color coordination is not my forte', so I'm open to any suggestion anyone may have.
just a quick pictoral, of me casting some floor tiles, from my master mold
so here's the 2 part resin, mix equally by volume, I just use cheapo plastic cups for this, and a peice of sprue to stir it all....little thicker then water when all mixed, but probably not as thick as table cream...
the big kahuna in action.....poured in to the mold, and starting to setup, you can get longer times, but I like not having to wait, 10 min and these are going to be ready to de-mold
A few shots over time, as it sets it turns to a solid white, you can see this happen before your eyes...
almost there, just the edges to go....since this is a chemical reaction, it happens quickest, where the resin is thickest, and takes the longest in the thinnest spots
10 min. later and we're all setup and ready to de-mold....I had some over filling, and you can kinda see some rounding....you can fill the mold too full and just like in a glass of water, surface tension will allow the product to be higher in the middle then the edge of the mold....nothing a quick sand won't take care of
after a few casts, we have a cup 'o' tiles, 28 tiles in this cup, I found with this product, 1-2 mm thick was still too flexible for my liking, so I added styrene to the bottom of my masters, to make everything a min. of 3mm thickSo after much trial and error, much experimentation, and much crafting...I'm finally ready to make my first master mold. This mold will consist of 6 different style floor tiles. The plan is to cast them as I need them, one at atime, with a single mold, accomadating all 6 tile styles...
so first up, rough layout...lego retaining wall built, and a mock up using some prior casts, and some first run tile creations (with the black edges) built on a foam core base....this is about 5.5" X 7.5" and about an inch deep
then we need to seal the bottom of the mold...here I used modeling clay (otherwise known as plasticene?) just roll it out, and smush it into the outside edge all the way around.

now I missed a photo for a step but it was just hot gluing my 6 tiles down, after making sure my table was level. Then I pour out and mix up the two part silicone....equal parts, when mixed together produces a blueish silicone.
after mixing up the silicone, I poured in to the cavity I'd made, pouring slowly, direct in the middle, and let the silicone find it's own level over and enclosing the parts....now to wait the 6 hours or so, for it to setup solid...so a few days ago, you saw my first attempts at some resin casting....this is part 2 of my (maybee) 3D space corridors project....I decided to go with a 45mm "tile" so the mini's I play with, look more realistic in scale (and it gives my fat fingers more room once walls are added)
for our very first "Compar-orama" we have the new Space Hulk Mini's on 3 of my cast resin tiles at 45mm, and on a 3 tile section from the actual game.....(based on a 30mm scale)
Real Game
My Casts
I'm not so sure...while the "game" tiles give a more "close combat" type feel and look, I really think it's quite crowded, and I didn't even pick big models in this comparo....
First up, my attempts at teaching myself the arts, of mold creation and casting...my first mold/frame and silicone pour....
here it is, all setup and de-framed....for a first time, it turned out pretty decent...Pretty happy with how that worked out, though it's a bit thicker then I need it to be....lesson one learnt!
First resin pour, starting to setup....I think I made a mistake during the mixing of the 2 part resin...but we'll hafta see
And there it is, first peice cast and de-molded? so my prior thinking was right, I did screw up the resin mixing....the final peice took about 3X longer to set, and way more flexible that it should be. Lesson 2 learnt....but the detail it captured is outstanding, and I'm very happy overall...First molding/casting experience has been very positive....now, to remold, and cast a number of real tiles, so I can start making floor sections for the 3d SpaceHulk project.
