the wax part also!
Um... That's not strictly true. The Xerox Solid Ink
printers - which are part of the Phaser series - are something referred to as wax printers due to their supplies looking much like 4 blocks of wax.
Only 'advantage' of wax could be that the material is re-usable, but how to revert an object into threads of the correct constant thickness
I went there too, but was also thinking it may be needed/wanted for some sort of casting operation where an internal mold piece may need to be melted out of a finished product. *Shrug* ...Just trying to get clarification on what we/re after.
