DIY: Making a Bionic Arm from EVA Foam

While we have previously shared David Guyton’s video tutorial on how to make a bionic arm from metal, he has just released a brand new tutorial on making one out of EVA foam!

While EVA foam is far less durable a material than metal, it has several distinct advantages over metal:

  • Some conventions have banned the wearing of metal armor. If you’re planning to attend such a convention in an armored costume, it will have to be made out of some other material, such as plastic or EVA foam.
  • EVA foam is much lighter than metal making it easier to wear.
  • While metal is a rather rigid material, EVA foam is far more flexible, which also makes EVA foam easier to wear.
  • Since EVA foam is a soft material as compared with metal, it’s much easier to work with than metal.
  • The tools & materials are less costly & easier to obtain for working with EVA foam as opposed to metal.
  • The skills required to work with EVA foam are easier to learn than the skills needed for working with metal.
  • Unlike metal edges that need to be sanded so that they won’t accidentally cut into skin, you needn’t worry about EVA foam edges being a potential safety hazard.
  • Unlike metal that can rust, EVA foam can’t rust.
  • You’re far less likely to disturb neighbors working with EVA foam because you don’t have to hammer it as you would need to do with metal.

The biggest disadvantages with EVA foam as compared with metal are as follows:

  • EVA foam is not as durable as metal (as previously mentioned), meaning it has a much higher chance of being damaged while being worn or stored.
  • Greater care must be used for storing EVA foam armor than with metal to ensure that it keeps its intended shape.
  • EVA foam armor is going to be much thicker than a metal equivalent, so additional allowances have to be made.
  • Replicating a metallic shine with painted EVA foam will probably never be as shiny as actual metal.
