LLLGuapo, looking very cool, i would love to see some of the work that came out of zbrush. the lion looks great, very strong forms.
lemonnado, looking good, yah alloys are getting expensive, as an alternative, you could cast them using a resin and metal powder mix, they still patina because of the real alloys in them but you use alot less material and it all cold cast, so your mold will last, and some burnish up very well.
i wanted to add that some new 3d printers can swap out there
resin for refractory material so you can print the negitive and pour directly into
the pc off the table, if you set it up right you could have it produce the negitive for your pour spouts, spruse, cores and pegs to suspend them in the shell of refractory, i love whare the technology is going.
