Hello, some time ago I happened to read this topic, in which it is said lego pieces can be melt using acetone, and I wondered "Would it be possible to use this molten plastic in molds to create recolored lego pieces?" There are many pieces that have never been made in this or that colour, one could make molds from the 'wrong colour' pieces and create what he's looking for
Still, I'm not sure acetone would evaporate properly since there's little to no exposure to air in the mold, and the inner part of the new piece might remain liquid anyway once the outer part hardened.
I'm quite new to piece customisation, I have little experience (I've always considered myself a 'purist') and I don't know if something like this has ever been done before.
What do you think? I'm curious to hear what you think :)
