REPLICAS IN CULTURAL HERITAGE: 3D PRINTING AND THE MUSEUM EXPERIENCE

<jats:p>Abstract. 3D printing has seen a recent massive diffusion for several applications, not least the field of Cultural Heritage. Being used for different purposes, such as study, analysis, conservation or access in museum exhibitions, 3D printed replicas need to undergo a process of validation also in terms of metrical precision and accuracy. The Laboratory of Photogrammetry of Iuav University of Venice has started several collaborations with Italian museum institutions firstly for the digital acquisition and then for the physical reproduction of objects of historical and artistic interest. The aim of the research is to analyse the metric characteristics of the printed model in relation to the original data, and to optimize the process that from the survey leads to the physical representation of an object. In fact, this could be acquired through different methodologies that have different precisions (multi-image photogrammetry, TOF laser scanner, triangulation based laser scanner), and it always involves a long processing phase. It should not be forgotten that the digital data have to undergo a series of simplifications, which, on one hand, eliminate the noise introduced by the acquisition process, but on the other one, they can lead to discrepancies between the physical copy and the original geometry. In this paper we will show the results obtained on a small archaeological find that was acquired and reproduced for a museum exhibition intended for blind and partially sighted people.                     </jats:p>

(SG) • The SG is to collect the GA documents (GA agenda and all supporting documents) in digital form and forward them to OdMs, AsMs, RgMs and HnMs as well as to Council one month prior to the Congress. The SG will distribute an update of those documents approximately 10 days prior to the Congress. For easy access, these documents will be stored on a separate folder on the dropbox. • The CD is to produce paper copies of all last-minute documents (i. e. those which are not in the dropbox folder, because they came in too late) to be distributed at the GA registration desk. The SG will distribute these documents to all attendees of the GA and also to Council in digital form as soon as they become available. • The SG is to produce a list of GA attendees (delegates and advisers nominated by the OdMs, representatives of AsMs and RgMs, HnM and guests) -for use at the GA registration desk. The list will be forwarded to the CD at least 10 days before the Congress. • From the list of GA attendees, updated by the SG immediately prior to the Congress, the CD will produce GA badges. The CD will deliver the badges to the SG before opening the registration of GA members. • For OdMs, the badges are to be named "Delegate, Country/Region" and "Adviser, Country/Region"; for AsMs and RgMs, the badges are to be named "Representative, Member Name"; for guests (e. g. people bidding for future positions within the ISPRS), the badges are to be named "Guest"; for HnM the badges are to show the name of the HnM and "ISPRS Honorary Member". Council Members and support staff (e. g. Annette, Dan, possibly others) will also receive GA badges, these will come with the label "Council".

All OdM delegates, including in-person attendees, will cast one ballot per individual vote via a personal device (laptop, mobile phone) using the email address registered for the GA for that OdM. Members should be informed that, should an inperson attending member delegate not be able to cast a vote due to lack of personal device, they should inform the SG as soon as possible to arrange an alternative device. • When using voting slips, numbers and colours are to vary for each vote and category, respectively areas of responsibility of Council Members.
