Yep, it's difficult automating the fabrication of some of the alloys. But we really want some challenges in Blackvoxel. Some future high end alloys will be even more difficult to make.
But we are also thinking about items that will help making alloys and understanding what is done. First, an heating machine that will re-heat the melted alloy preventing it to cool down where you doesn't want it to(in the mixing tank). And yes, some way to analyse the molten alloy before it is cooling down like they do in real life factories.
In the test phase, we used a kind of analyser and we had found it's very fun to play with that. But we hesitate between an analyser unit, some kind of "analysing goggles" that might also give informations about some other voxels. Another idea we will certainly do anyway is to give to the programmable robot the ability to get some detailed informations about a voxel. That would include some of the alloy composition.
