Introduction: Iron Man 3 Arc Reactor.

Picture of Iron Man 3 Arc Reactor.

As has been said in my previous Arc reactor instructables, I love Iron man.

first Arc

Whiplash Arc:

iron man 2 arc:

So with the imminent release or the third instalment of the iron man movies i decided i would give the arc featured in the trailers and posters a go. 

The Arc i have made is made and designed is based wholly on the one shot, so i have no idea on how deep the arc is, ive used my past builds on the other arcs to guess the levels and design of this arc. 

So here goes :)

Step 1: Tools and Materials.

Picture of Tools and Materials.


- files
- sand paper
- knives (scalpel, exacto, craft)
- rulers (any straight edge)


- 3mm perspex
- 2mm perspex
- thin card (0.7mm i don't know the gsm)
- solvent glue.
- spray paint.

Step 2: Research, Planning and Drawing Up Plans.

Picture of Research, Planning and Drawing Up Plans.

I got some images from google, by googling "iron man 3 arc reactor" and had a look at how the arc is designed.

what i like about this design is that it moves away from the Vibranium triangle from the second film. i love the round designs.

I did some sketches of how i thought the layering would work to get how thick the arc would be.

once i had worked out the layers i drew up some illustrator plans.

Step 3: Cutting the Parts.

Picture of Cutting the Parts.

i cut all the parts from the plans out on a laser cutter. but as has been shown by user : 159753 in the comments of my last arc instructable who made all the parts with a dremel, so it doesn't have to be done on a laser cutter.

Step 4: Assembling the Cut Parts

I gathered up the parts into groups that will be glued together.

the rear ring assembly.

the arc ring magnets.

the oval ring assembly.

Step 5: Painting the Parts.

Picture of Painting the Parts.

I gave all the parts that are going to be painted a coat of plastic primer and then the colour of its parts.

The main body and the ring magnets are silver.

The front bezel and the parts the go on top of the oval ring are black.

The oval ring and hexagon mesh (which was cut from the thin card.)

The rear ring assembly was painted gold.

Step 6: Oval Ring Assembly.

once all the paint had dried i started putting things together.

I glued the hexagon mesh to the rear of the oval ring.

After cutting out the parts i kept the waste of the parts that sit on top of the oval ring as it would help locate the parts on the oval ring.

once the glue for the first two parts had dried i turned it over and attached the gold rear ring assembly to the back of the oval ring.

Step 7: Main Arc Ring.

Picture of Main Arc Ring.

i took the protective plastic of the main clear ring and glued the from halves of the ring magnets on the clear ring.

Once the glue dried i turned it over and glued on the back plates of each magnets.

Step 8: Final Assembly.

Picture of Final Assembly.

The front glass is made by etching one design on the front of some 2mm perspex then turning it over and etching the second design on the back. This technique gives you depth to the design I chose to do it this way because the source image I had looks like there are two layers to the arched and geared design. I put all the parts together with a disk of EL panel in the rear of the case.

What are the risks of building it?

backwards lamb (author)jchinn2016-05-10

im not sure what you mean, this is in no way a working arc reactor its a prop replica with a little battery that powers a light.

The risk of making this are you might cut youself or get glue on you or paint fumes?

How tall is it? I was thinking of using sfx makeup to make it look like its embedded in my chest, but I need to know its height.

Could you attach laser cutting files

cleomaru (author)2015-04-12

Up next? How to make your own laser cutter?.....

which colors did you cut on your plans and which did you etch?

hi, i think it was blue for cut and green line etch and black or red fill for rasterising.

it doesnt matter (for the most part) what colour one uses, unless you actually have my plans then it can be quite self explanatory as the lines on the outside of the drawings are normally the cutting lines then you can work back from there.

You mean iron man 1 arc reactor this is mk 1 not mkV

yagos7 (author)2013-05-02

How much do you charge for the plans? what include on the plans?

backwards lamb (author)yagos72013-05-13

if you go to my website and email me through that i will answer all you questions regarding plans for items.

bknott1 (author)2013-05-09

How did you get this to light up? Did you jsut illuminate it from behind? I'd like to make one that lights up by itself :) Welld one thugh, it's awesoem!

backwards lamb (author)bknott12013-05-13

it lights up using an EL panel at the back of all the parts.

Hey. where did you get the light from the reactor? and can i cut the parts without the sketches? thnx. ~^_^

i mean without the plans?

isaac.gunther (author)2013-04-20

Do you sell these?

no sorry i do not, but i do sell the plans.

Mr.Sanchez (author)2013-04-04

Nobody doubts that you freaking love IRONMAN. Biggest Fan ever.!!

this i very cool i am SERIOUS THIS IS AWESOME

Actually, form the photo you based on, this is not the reactor. The photo is from the chest assembly in the armor, the thing that draws the power from the reactor. But your project is very nice looking and I like it very much. I wish I had access to cutters to make one like this.

Yeah i know that but i didn't think "iron man 3 uni-beam" had as much draw as "iron man 3 arc reactor." :)

I think that the reactor will be the same triangle shaped, what do you think?

Yeah the arc will be a palladium core arc but it will be a different design as he always changed the design. The drone suits and war machine will have ones like this in them.

What diameter you think a reactor has?

i dont know. depends on what you scale it to. i think my designs have a size of around 90mm

90mm looks like the original design. I'll try it. As you can see from my pic, I already made a reactor, but it overheated and the diodes fused. I'm redesigning it.

THis is amazing work! Do you ever so slider selling them? If yes how much?

So awesome!! This really looks like a movie prop.

Thank you . i really enjoy making these. :)
