Hahaha SB you beat me to posting my first retraction...
In the beginning of this journey for me anyway I started as follows...
Foam: Buying all the tools and research time and actual build time. Status abandoned, not what I hoped for functionality wise.
Cardstock resin: A whole lotta mess with limited space, I just couldn't do it.
Metal: Still in the R&D stage.
But I think cost of the build comes down to how intense the build that you want. They all need tools, research and time. Soif your starting from scratch, this can be expensive anyway you look at it. Crap I've been here for 4 years and I still have yet to build a complete armor. Lots of small pieces for my daughter, but just R&D for me. Maybe I am just an idea man...GM
I know what you mean mate.
Paper pepakura - printer, cardstock, resin hardening, reinforcing with fibreglass mat, slushing with rondo, building for smoothness and detail with bondo, prime, undercoat, paint, topcoat, lights and electronics, padding, fastening and strapsystem, dust, smell, protective breathing apparatus, drop cloths, nuts, bolts and screws, chemical overalls, gloves, files, sandpaper, painting equipment etc.
Ups - Looks great, light weight and solid.
Downs - Time-consuming, brittle, limits movement, dangerous organic chemicals and dusty work.
Foam pepakura - printer, template paper, hot-glue and gun, (comes unstuck a lot! Especially in the heat.) foam mats, knife, straight edge, spare blades, cutting mat, heat gun, sealer, prime, undercoat, paint, topcoat, lights and electronics, fastening and strap system, nuts, bolts and screws, smell, protective breathing apparatus, sandpaper, painting equipment etc.
Ups - light weight, readily available and reasonably cheap materials, quick builds, comfortable and flexible for movement.
Downs - damages easy, difficult to finish surface, hot-glue prone to releasing in hot environments
Metal - printer, inks, template paper, cardboard for custom tailoring,hotglue gun and glue, knifes and blades, cutting mat, straight edge, steel sheet, tin snips, drills and bits, welder, welding wire, welding gas, grinder and disks, files, sandpaper, all kinds of hammers, anvil, dollys, vice, grips, crimps and brakes, nuts, bolts and screws, personal protective clothing, rustproofing, sealer, prime, undercoat, paint, topcoat, lights and electronics, fastening and strap system, smell, protective breathing apparatus, sandpaper, painting equipment etc.
Ups - Looks awesome, sounds the goods, cheap material, very tough, easy to assemble
Downs - heavy, limits movement, tool and skill intensive, time-consuming
So as you can see, there are advantages and disadvantages to both. I personally think it all comes down to your skill sets, how determined you are for a particular standard of finish and how much time, resources and money you are willing to throw at it.
