Creating things out of Eva Foam!
Creating things out of Eva Foam!
Here is my personal process for creating things out of Eva Foam, I highly recommend also checking out the videos I linked in Videos on the Helpful Resources page for more detailed information by actual professionals! First why Eva Foam? Eva Foam is a material that is easily moldable when adding heat. This is why so many prop makers use it! You can cut out your shapes and then apply heat to bend them to how you want them to look. If held in that position for long enough they harden and stay.
Box Cutter, Heat Gun, Contact Cement, Eva Foam (Duh), A filler, sand paper, spray paint, Scissors, paper, and anything else you feel might be a good tool for the job on the way use it!
Know what you want to create! In my case I was set on creating a set of Mandalorian Armor. I will be using all my projects to highlight different parts of the process. How would I do this? With Eva foam of course! Iv linked where I got my foam in Helpful Resources!
Finding the right templates or creating your own is the next step. I my case, for the helmet I used a template that can be found in Videos. For this step I cut out templates and then traced them on to my sheets of foam, then cut out the pieces.
Here is a close up of one of my old chestplate. You can see there is a line down the middle this is because making templates is simple! Just draw one half of the armor piece you want to create, trace it, and flip! flipping the half template insures that your piece will be symmetrical! - Side note, if your wondering how there are angle cuts, I just used a box cutter and cut on an angle to get that look.
Contact cerement is toxic! You should make sure to use it in a well ventilated area. Contact cement also takes a lot of patience to master. To apply take a brush (that will get ruined) and paint it on to both sides of where you want to fuse parts together, BUT DONT PUT THEM TOGETHER! Yes thats right you apply the stuff to both sides and then go make yourself a snack and come back 15-20 minutes later and then carefully bond the pieces together. 17 minutes was how long I found it took to get maximum stickiness.
After using contact cement you will find that there may be some gaps in the connection. This is where a filler comes in. There are many ways to do this. The images to the left are two ways I have used, but just using simple wood filler works too! After filling be sure to sand and smooth out the surface.
This could also be called griebling. Adding parts that aren't necessarily Eva Foam can give your build some flare. As you can see I used different nerf darts and a prop bullet to create a missle launcher on my gauntlet. Dont worry about the colors and what it looks like you will prime and paint over it all eventually.
Sealing is one of the longest steps so strap in! There different ways to go about doing this but I'm going to list the 2 ways iv done it. First make sure to go over all your pieces with a heat gun. to close up the "Pores" in the foam. Be careful not to burn the foam! evenly spread the heat across each part.
Plasti Dip comes in a spray can and it essentially is like a primer for your eva foam. It seals all the tiny pores the heat may have missed and gives you a nice base coat to work with. The down side of Plasti Dip is 1 you need a lot of it, and 2 you have to use sandpaper to sand down the rough surface it creates.
FlexBond is what I used for my most recent Eva Foam project and I recommend it over Plasti Dip. Pros: You need much less of it (didn't even go through half a gallon for all my parts) 2 No sanding! Cons: its a mess!!! The mess is manageable but it is a glue so its very sticky and tends to get everywhere.
Here you can see where my dad I hung all the parts and then primed and painted them! This step is pretty self explanatory. First find a primer that goes with whatever spray paint or airbrush paint your using and apply it and then paint!
Strapping differs between everyone! This can be done in whatever way you see fit. Clips, snaps, in my case Velcro (Which is not a permanent solution, but it works for good days worth of wearing the outfit. Here you can see my friend sewed on Verco to a tight shirt so that I could wear the armor. Strapping can be done before or after painting, It all depends on the situation, I personally did strap before I painted but I found that some of my straps would get paint on them so I listed it last.
Thats it! That is a layout of my basic process for creating foam armor! Below is some more information that might help!
This is a test fit. For this armor I used a base plate that I strapped around me and then glued my armor to that.
Here I used Velcro to get everything to stay to me. Another test fit before painting
Here I used foam to support my head. I also added fans to the back to defog my visor. This is a whole other process that I recommending finding information elsewhere... My design passed for about a day before breaking
Here you can see I also prototype certain things. The moving visor design was made on a throw away helmet so I could make sure it worked and then I made an official helmet that I would then add the final design to.
Laying out Armor pieces to dry
Weathering is something that isn't necessary but definitely recommend to give your build depth. I just dry brushed silver on to the seems and not perfect parts of my build
Small pieces of foam help add detail to your armor pieces and can really make a difference
Final Pieces ready to wear!
