Since 2005, at the Archaeological Heritage Office of Saxony finds are digitised by high resolution 3D scanners. Until today more than 17500 objects were 3D scanned. A large number of finds are fragile and shifting organic objects. After documentation the finds will be treated and freeze dried to make them stable for future procedures. Ideally a find should not change in dimensions during the process of treatment and after drying. In reality partially massive changes were recorded which has to be quantified. Within the ongoing EU-funded binational project ArchaeoMontan more than 1000 wooden finds have been excavated, documented and digitised with 3D scanners, thus a reference measurement of all finds are existing in high detailed 3D models. In order to determine the amount of changes in volume and shape, all objects will be scanned again after the freeze drying process. Deviation analyses are showing detailed information about the success of the conservation. For now monitoring measurements with 3D scanners are also used for exhibition objects which are exposed to various additional influences too. The paper will demonstrate methods and experiences, and will present intermediate results of monitored measurements. The resulting applications relating to exhibition objects will lead to the discussion of further rewarding tasks supporting the lending management in museums.
