We’re starting to become a repository for Arc Reactor replica projects. The one shown above uses mostly laser cut components. We missed it back in May when [Valentin Ameres] tipped us off the first time. But he sent it in again after seeing the 3D printed version earlier this month.
Our biggest gripe is that we don’t have our own laser cutter to try this out on. Everything has been cut from 2mm thick acrylic. The black, silver, and copper colored components were painted to achieve this look. Many of the clear parts also had a dot matrix etched into them to help with light diffusion.
Basic assembly just required the parts be glued together. The finishing touches include wire-wrapping the slots of the outer ring and adding LEDs and current limiting resistors.
The plans are not freely available, but the 3D printed version linked above doubles as a 123D tutorial. That should help get you up to speed designing your own if you are lucky enough to have time on laser cutter.

[James] just keeps cranking on the idea of the perfect arc reactor replica. This time around he’s made most of the parts using a 3D printer. His write-up covers the basics of the build, but he also used this opportunity to make some tutorial videos on designing the parts using Autodesk 123D.
This is definitely an improvement on his last prop, which was built out of dollar store parts. When designing the components he tried to be as true to the original movie design as possible, while keeping in mind the limitations of using a home 3D printer; he printed them on a Lolzbot AO-101.
The videos below give you a good idea of what it’s like to model parts using 123D. The tool set is pretty simple compared to something like Blender 3D. But [James] uses them in such a way that the components get complex fairly quickly. The second video includes some footage of the parts being printed, as well as the assembly process that adds wrapped wire for looks, and LEDs for illumination.

Following in the footsteps of [Tony Stark] this Arc Reactor replica was hand crafted using almost no power tools. From what we can tell in his build gallery, a cordless drill was his only departure from using pure elbow grease.
[DJ Maller] started his build by cutting out a disc of acrylic for the base plate. While we might have reached for a hole saw, he grabbed a framing square and laid out a center point and square cuts on the stock. Kudos for his use of an awl (we often take the Luddite approach of hammer and nail) to make an impression for his compass point to rest in. After using a coping saw to rough out the shape he sands the round up to the line with the drill and a sanding wheel.
After drilling holes and inserting LEDs he begins to build up the replica piece by piece. What looks like a recessed handle for a sliding closet doors makes up the center. The spring-like copper coils was produced by wrapping wire around a pen then stretching to the desired shape. He added a bicycle spoke wrench wrapped with copper for some additional visual appeal before finishing the decoration off with some storm door clips.
Thinking long and hard about how to propose to his girlfriend, [Ed] hit upon a great idea: use an arc reactor as the ring box, with enough LED lights to outshine all but their love, and servos to present the ring and tug at the heartstrings.
[Ed] set about giving his now-fiancé from his arc reactor heart by building a simple circular arrangement of adafruit RGB LED strip and an Arduino. There are two modes for this arc reactor: a light up mode that simply looks awesome, and a ‘ring mode’ that uses two servos to open the front cover and bring the engagement ring into view.
After [Ed]’s fiancé said yes, the cover in the center of the arc reactor closes for its continued use as a desk ornament. You can check out [Ed]’s proposal contraption in action after the break.

Some people have a real knack for sourcing parts at the dollar store. [James] is one of those people, having built this Arc Reactor replica using mostly dollar store goods.
The light source is an LED disk light that was removed from its enclosure. A sink strainer, the plastic holder from a package of sewing pins, and some wire mesh go together to make the first layer of the bezel. The push-pin holder is what has the ring of narrow rectangles around the bright center. It was painted black and attached to the sink strainer which provides the concentric holes in the center of the device.
For the detail around the outside [James] went with some clear-plastic drinking cups. By cutting off the top centimeter of each and stacking three together he gets the clear base he was after. The rest of the parts were gathered from his electronics supplies. DIP sockets straddle the drinking glass rims, and are wound with copper wire for the look seen here.
We put this near the top of the dollar store builds along with this Blade Runner umbrella.
Halloween is the time of year where you can dress up as a pirate, muppet, or superhero and no one will bat an eye. During this holiday of expanded social permissiveness, [Nbitwonder] decided that building an Arc Reactor from Iron Man would be appreciated by his engineering cohort.
The ‘body’ of the reactor was manufactured on the RepRap Mendel we covered from beginning to end. A few minutes with Google Sketchup was all that was needed to generate the files and send them to the printer. In a few short hours, [Nbitwonder] had the body of his Arc Reactor.
The board design was thrown together in Eagle and etched. 11 blue SMD LEDs were thrown into the mix along with some borrowed resistors. Pieces of a hard drive spindle and a little bit of wire rounded out the parts list, and everything was assembled with the DIYers favorite tool, the hot glue gun. Not a bad job for a few hours of work.
The files for the Arc Reactor are up on Thingiverse along with a Flickr photoset.
This Arc Reactor is a great re-creation of the fictional source of Iron Man’s power. It’s really just a holder for a bunch of LED’s, but it exhibits some fine craftsmanship which we enjoy in any project. This rendition is much more true to the movie than the last look-a-like we saw. These might end up being for sale (the webpage narrative is kind of weird) but you really shouldn’t be wearing this kind of thing around unless you made it yourself, or if you can add it to some kind of Iron Man simulator.
