Hi Guys,

Has anyone here been able to cast parts?

I remember someone mentioning being able to make parts from Polystyrene which is the same plastic used for disposable cups and such. It is a plastic which is easy to melt and solidifies at room temperature into the shape of it's container.

I wish to be able to replicate a missile part which is otherwise impossible to acquire by itself. Does anyone have any experience with this?

Sadly not, it's always been something I wanted to try. Theres plenty of resources on the net about diy moulding of various plastics.
I wouldn't recommend polystyrene on it's own though, you may want to 'alloy' it with ABS plastic for extra strength.

Unfortunately I have no idea how workable this goop is.

I think Kelvinchang99 has either cast parts or knows someone who does.

Just out of interest, what part are you trying to replicate?

MOTU 200X Castle Grayskull missile :) It seems impossible to find one loose anywhere.

Obviously it's not a Transformers part but since the process can be used for general toy repair, I thought I should make a thread here for general reference.

I have been researching and found this place:

I like how they make a mold out of that putty like substance (they have a video). It seems workable for what I am trying to do.

With the AUD so strong why don't you try out Aluminite or Smooth-on stuff. Casting stuff is something thing I've yet to try out but the starter kits look pretty good.
