yes I'd be interested - for $1000 - not a chance.

For that money it'd need to be fuly portable. And as a lot of people would like to scan other (and their own) people's heads - that's most likely why it would need to scan bigger than the printer can scan. Also scan larger objects and rescale them for printing.

For a printer add on I might go to $400, but certainly no more for somethig that limited.
