Special Issue Information
Dear Colleagues,
It is my great pleasure to invite you to submit your most recent research related to replicas in Cultural Heritage.
The development of 3D technologies has led to important results in the areas of conservation, enhancement and use of CH.
Digital fabrication is one of the latest developments within the range of technologies applied to the CH context. However, it is only one step in the extensive process of data acquisition and management: the final moment of the workflow, from recording the shape of the object to its physical reproduction. Because it is part of this process, manufacturing technologies, which are involved in the realization of replicas, using "subtractive" or "additive" techniques, are closely linked to those for metric data acquisition (point cloud production) and digital data management. The use of 3D printing processes based on metric surveying enables production of objects that replicate the true shapes. The "point cloud", meaning the digital point model obtained by photogrammetry or laser scanning, can be saved and archived, providing a record of the true state of an object in a given space-time context, and these models can then also be modified or replicated as desired.
The production of the physical model requires machine operations which are themselves characterised by different levels of accuracy. Different printers utilise different methods and materials to translate the virtual model into the physical replica, as suggested by their names: computer numerical control (CNC), sterolithography apparatus (SLA), fused deposition modelling (FDM), selective laser sintering (SLS). These different choices imply different accuracies and resolutions. The digitally produced replica will be more or less simplified, depending on the selection of printing technique and specific device.
Today researchers often use these three-dimensional digital models and printed replicas for purposes of data collection and analysis, thereby avoiding physical contact with sensitive objects and exhibits. Researchers and technical experts can also share digital models on a global scale, and the public can enjoy museum collections in richer ways, through the experience of physical replicas.
This Special Issue brings together scientists, developers and advanced users in 3D data acquisition, processing and 3D printing aiming to encourage cooperation and practice sharing in the various fields where 3D technologies are nowadays used.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
