Dead Space 3 Plasma Cutter

I was recently commissioned to build a replica of the New Dead Space 3 Plasma Cutter. Personally, the style of the new Plasma Cutter is my favorite so far so I was very excited to get the opportunity to build it. The goal for this project is to not only incorporate the iconic three-point laser sight into the design, but also allow the front of the cutter to rotate as it does in the game. To get started I gathered up any and all references I could find of the new Plasma Cutter including an excellent concept sketch from the dev team limited edition of the game. Using these references I then drew up some blueprints to give myself a template for creating  the pieces and scaled it to the right proportions. Coming in at just over 16 inches this is going to be quite intimidating when completed. You can see a sample of the blueprint below.

I began gathering materials and hardware almost immediately and the first components to arrive, and perhaps the coolest part of the build, were the lasers! After much research I decided to go with mini blue laser diodes due to the small amount of space available in the front of the cutter. There are three in total (of course) each wired to its own micro boost drive and connected to the power supply. Unfortunately these lasers wont be powerful enough to light matches or pop balloons and you won’t be able to see the beam itself without some atmospheric assistance ( smoke, etc.).  Lasers that can do all of these things can cost hundreds of dollars for a single laser. However, these lasers are still very bright and fairly powerful so common sense still applies when it comes to not shining them directly in anyone’s eyes and eye protection is still recommended. One of the laser diodes was defective when it arrived so a replacement has been shipped and I am waiting on it to arrive. The other two are shown below. The lasers don’t translate all too well in the photographs.

The first two pieces to be completed for the plasma cutter are the two front “arms”. These were created from a combination of styrene, PVC, Bondo, and other epoxy. These two halves which make up one side of the plasma cutter will be molded and flipped to complete the other side.

The plan going forward with this project is to build the cutter and all of its components in halves. The reason for this is so that custom spaces can be created for the internal components, to allow these components to be easily accessed in case they need repair or to replace batteries, and also for molding purposes. I quickly mocked up the pieces I have so far on top of the blueprint I created to gauge where I’m at.

Above are just a few of the pieces that make up the head of the plasma cutter.

At this point the front end of the plasma cutter has been completed except for the placement of screw holes which will be added later to allow the two halves to be screwed together in the correct position. The laser diodes fit inside the two halves snugly with circular rests in front to hold them in place. The wires will travel out the back and into the body of the plasma cutter and the power source.

Perhaps my favorite part of this build so far was unintentional. The laser diodes themselves are too large to allow the middle laser to be placed as far forward as the ones on the top and bottom. This meant it had to be placed towards the back of the cutter head. What this also meant was that a hole still needed to be made in the front of the cutter to allow the laser to travel through from the back of the cutter head. This ended up creating this cool open area in the middle of the cutter head where the laser has to travel though which i think adds a nice touch to the overall design. This is illustrated in the photos below.

With the two halves of the cutter combined this build is really starting to come together and I am stating to get even more excited. The two arms on the front of the cutter still need to be molded and duplicated to complete the other side but these photos should still give you some idea of how this will all come together. A post has been placed on the back of the cutter head to connect it to the body once it is completed. The notch that has been placed along the post will allow the front end to rotate and stop in the correct position.

Next up the plasma cutter body.

    Can’t wait to see this finished and see it sit there and rotate back and forth.

    cant wait to see more pics!
    looks awesome so far!

    are you going to sell the plasma cutter???

    • Skylow Studio July 5, 2013 at 2:15 pm #

      Yes, once the Plasma Cutter is finished and I make molds of it I will be able to produce more. The person who commissioned the work with get the first copy and I will be able to take orders for more after that.

    Wow! That looks amazing! I can’t wait til you finish this one, because I’ll definitely be looking into ordering one of these.

    How on earth did you get the cuts so precise with each piece?

    • Skylow Studio August 14, 2013 at 4:16 pm #

      By being very diligent. I am using only hand tools and sanders at the moment. A laser cutter would make things like this so much easier. Ahh… someday.

  6. Hunter August 13, 2013 at 5:58 pm #

    Any updates at this? I can’t wait to see more of it.

    • Skylow Studio August 14, 2013 at 3:41 pm #

      Yes, all parts have been cut and I am doing the test assembly now. Once I get everything sanded and primed I will begin molding. I will be posting more pictures soon. Be sure to check our Facebook page for updates as well.

        Thanks for the update! I’m excited to see it come together!

    Are you planning to make it be able to fire? And if so, only one projectile or simultaneous 3-burst fire? Because seriously if you make a plasma cutter that fires 3-burst shot with those laser aiming I seriously will lose my mind and just give you all my money lol

    • Skylow Studio October 7, 2013 at 9:33 pm #

      While it does not fire any projectiles (there is just not enough room inside the prop for that kind of mechanism) it does have three lasers that activate when the trigger is pulled similar to in the game. And yes, the front of the cutter does rotate 90 degrees but the rotation has to be done by physically turning it with your hand (again, because there is simply no room for the motors necessary for that kind of automatic rotation).

      -Thank you

    Also, barrel rotation 90*?

    Hey there Skylow! I just figured this was a fitting place to post a link to a page with photos of my own Plasma Cutter project. I will admit, I only managed to accomplish this by referencing the blueprint you started with. I pulled the image from the blueprint and used it as a template to develop a full 3D model of the cutter in a CAD program. Someday soon I hope to gain access to a 3D printer so I can create the most accurate replica possible and without the need for cutting all the pieces by hand. I hope you enjoy!
