Walk Like A Xenomorph

[James Bruton] is busy working on his latest project, a “scrap metal sculpture”-inspired Alien Xenomorph suit.  However, he wanted to get a boost in height as well as a digitigrade stance. To that end, [James] 3D-printed a pair of customized stilts. Each stilt consisted of a lifter with several parts laminated together using acetone. He bolted an old pair of shoes onto the stilts, adding straps across the toes to keep the shoes from lifting up.

While the stilts worked very well, [James] wanted to add soles to them to give him some traction as he walked – falling while in a Xenomorph costume composed of sharp plastic sounds painful enough! He decided to hybrid print the soles using ABS and Ninjaflex. The ABS part of the sole was then acetone-welded to the bottom of the stilts.

[James] hopes to add some claws for effect, so long as they don’t impede his walking too much. He has already completed a good amount of the 3D-printed suit. We know the finished project is going to be amazing: [James] has created everything from Daleks to Iron Man!

  1. “acetone-welded”
    As a plumber I see this as a safety issue. When cementing plastic parts together (or “welding” as it is described here), a primer of some sort (acetone, in this case) should be used to prepare the plastic surfaces being joined but then should be followed up with some kind of cement that contains a filler material. When joining PVC pipes, the mating surfaces are first brushed with PVC primer, then coated with PVC cement. Only then are they joined, and once the cement cures you end up with a solid joint or “weld”. If nothing else, the cement serves to fill any voids, making a much stronger joint.

    I would never trust those to support the weight of an adult.

    1. Yeah, it probably won’t hold water pressure, but for costume work, it’s probably quite fine. Correct me if I’m wrong, but PVC is not as soluble in acetone as ABS is, so the bonding force with ABS would probably be much stronger than just using acetone on PVC.

  2. Ok I get that he’s into 3D printing and all but why the heck didn’t make those simple stilts out of plywood or something? The rest of the suit is all curves and intricate small parts but the stilts are like two hours with a drill and a figure saw, max.
    Right tools for the job man…

    1. Hey JJ,
      Where are *your* HaD posts and projects?
      Oh wait, just another whinger. Sad really.

      Disclaimer: I know James, and his projects and ability are nothing short of awesome. If he posted 1/10 of some of the stuff he’s built over the years, many of these pathetic “not a hack” and “Can’t you just buy that?” commentators would be put to real shame. Keep it up lad, and ignore this waste of comment space.
