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.

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.

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.

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

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

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

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)  bknott11 year ago
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?
Do you sell these?

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?
backwards lamb (author)  I_StarkGuy2 years ago
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?
backwards lamb (author)  I_StarkGuy2 years ago
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.
