Now that is very thought provoking. Is anyone making wax patterns with
one of these CNC extruders? Being able to CNC a pattern for lost wax
casting would be just the thing when hot-wire cutting of polystyrene
foam has trouble with the shape, e.g. due to fiddliness.
Maybe it's practical, if the print head did not fully melt the wax, but
higher temperatures could still do so, to void the mould?
