Insect 3D-Printer

A 3D-Printer that uses the technology of insects like wasps or termites. The material to be processed could be produced from a mix of wood dust and some liquid to simulate the process happening inside the insect. This reactor would probably need some technology for good mixing an (unlike insects) a regulated temperature for best results. The printer would then print the self hardening material in the form desired. Advantages: Material would probably be cheaper than plastic The product would be bio degradable. No waste - just compost
