Arc Reactor from Iron Man 2 by Landru Oct 24, 2012


This is my version of the Iron Man II Arc Reactor.

4 printed pieces, (28) 5mm white LED's, (28) 0805ish 820 ohm resistors. Lots of soldering. Superglue. 12V power of some sort.

Any suggestions for how to attach this thing to your body/clothes? It's time to get my Halloween costume ready :)

Awesome dude! Thanks! I'm going to be wiring mine up this weekend. I'll post it when I'm done.

Hey Landru,

Just as an update, I tweaked some more settings and I did finally get a very nice print. Thank you again for your hard work on fixing this!

Print out all 4 Pieces. Low layer height is necessary on the coils and core to minimise the 'stairs' effect.

Also, the parts are designed for .4mm extrusion width. Anything other than that is untested.

Everything can be black/grey ABS except the diffuser, which should be made from transparent blue PLA at lowest infill.

4 LED's need to be cut/sanded down to fit in the center 4 holes.

The resistors are a bit awkward since I used 0805 surface mount versions. I did this all in 1 day with what I had on hand, so no apologies. Don't try this if you don't have good soldering skills. You have been warned.

I've uploaded some of my pictures of the wiring, but because there can be so many variations I will let you decide on your own details.

EDIT: July 13 2013 - Added Core and Coils with wider slits to aid in slicing with some software.

This thing was very hard to print. Slic3r hated it, but it all came out except for the core, which seemed to start printing a few millimeters from the actual bottom. Pics to come soon!

I added core and coils with wider slits. Hopefully that makes it easier for some slicers to handle.

You say that the resistors are awkward since you used 0805 surface mounts; if you were to do this again, what kind of resistors would you use?

Landru on Jul 13, 2013 said:

If I were designing it again from scratch, I would use a PCB with surface mount resistors and LED's.

The problem with the surface mount resistors is i was soldering them to regular wire (not a PCB) and that is rather hard.

ReplicatorG keeps crapping out on the Reactor Coils not sure why. Granted I'm still new and don't know the guts of gcode and such. 

Division by zero errors and comb.py freaking out. Any thoughts? Running Build 0037

Did you ever figure this out? I'm running into the same problem with both RepG and Makerware.

The same thing has been happening to me. 
I've messed around with the settings but even with 0 infill and 0 shells it will still error out. It seems to be a problem with the file itself.

can you send me the cad i wanna work it on catv5 so stp file

it will be pretty apprecieded because i use it for my final projet in my technical institute in montréal i give you my email [email protected]

I uploaded the .step file for you.
