Re: Vacformed Warhammer 40k Space Marine Armor - New Helmet Prototype on p. 14
I would be interested to know how much these beasts cost you to make.
I haven't really been keeping track of the costs. I do know that I dropped $1200 on sheet styrene and ABS last week to get ready for the crew to come by over the weekend. That's probably most of what I'll need for five suits. There's also the cost of moldmaking silicone (I'll probably burn through 44lbs by the time I'm done) and casting resin (about a gallon worth of cast parts per suit) and finally the stilts that I'll be building into the legs. I've gone through about a dozen gallons of fiberglass resin since the beginning of this project and probably at least as much bondo.
After you get over the cost and 100's of hours to make the bucks (which would add a lot to the sale price of a suit) how do they work out cost wise in relation to casting them.
The reason for vacforming them is to save on weight. If I was rotocasting all of the parts, this rig would weigh hundreds of pounds. My Halo Spartan suits weigh around 50lbs when they're fully assembled, so extrapolate that out to a character that's eight feet tall and four feet wide and you've got a costume that nobody could wear.
Is the material and process for vacforming cheaper than casting in molds or is it just an easier / quicker process ?
Both. For the Halo project I went with cast parts because of the much greater volume of details involved in those suits. Since the Space Marines have large, smooth areas, there's no need for the fine detail reproduction afforded by silicone molds.
If I get really insane somewhere down the line, I may graduate to making fiberglass molds and blow in the parts with a chopped strand gun. That'd be years from now though.
Once you have make your master is it quicker to make a vac buck or casing mold ?
The masters are the forming bucks. Making a mold would require more work and materials after the masters were made.
Due to the size of the suits and the making process does the amount of waste from vacforming make much of an impact on the cost ?
We've been trying to minimize waste by arranging the parts as efficiently as possible on each pull. It still takes somewhere between 20 and 30 pulls to make a full suit though, so waste is inevitable.
For an idea of what something like this should cost, think of the price of a suit of stormtrooper armor. Now realize that that would only be six or seven pulls at the most on a machine like mine. The full-sized Space Marine will take 4-5 times the plastic sheet plus whatever cast parts are involved...
You can do your own math, but if someone tells you they can build you a costume like this for less than $2k-$3k, hold onto your wallet.
