is shapeways alumide bind by nylon? nylon bond become unstable and release toxic cyanide hydroxide at those temps mentioned in above post.
personally i think using a single metal and having it machined is best, but the printed/binded/infused stainless steel will handle the temps in theory, although i don't know how structurally sound it is, and i wonder what its thermal stress would be because it is infused with bronze. also i wonder if it is porous? i bet it will still need to be machined, and will leak throughout the part. sorry for the negative context, just trying to save misery. for the cost of the print, i would invest in a drill press, and some carbide bits, and then get a piece of stainless steel.
this is only my opinion. others may have better offerings....
