Last year visiting RapPro in Veldhoven (NL) a prototype was shown of a K8200 printer modified to print clay (or more general: Liquid Deposition Modelling).
Has somebody any information on how to modify a K8200 in order to enable Liquid Deposition Modelling (Mechanical, electronics and firmware?
From what you have said it sounds like you are talking about the K8205.
