Additive manufacturing technologies are widely used in industrial settings and now increasingly also in several areas of medicine. Various techniques and numerous types of materials are used for these applications. There is a clear need to unify and harmonize the patterns of their use worldwide.

This article gives an overview of the main requirements for medical imaging affected by needs of AM, as well as provides a brief literature review from existing clinical cases concentrating especially on the kind of radiology they required. As an example application, a pair of CT images of the facial skull base was turned into 3D models in order to illustrate the significance of suitable imaging parameters.

An alginate impression was taken from the upper and lower jaws of a patient with temporomandibular disorder owing to cross bite and wear of the teeth, and then digitized using a table laser scanner. The scanned model was repaired using the 3Data Expert software, and a splint was designed with the Viscam RP software.

The manufactured scaffolds could be suitable for tissue engineering research.
Objectives: To design novel trachea scaffold prototypes for tissue engineering purposes, and to fabricate them by additive manufacturing.

Background: Additive manufacturing (AM) is being increasingly used for producing medical models. The accuracy of these models varies between different materials, AM technologies and machine runs.
Purpose: To determine the accuracy of selective laser sintering (SLS), three-dimensional printing (3DP) and PolyJet technologies in the production of medical models.
The possibilities of medical applications of rapid prototyping are continuously expanding and developing. In current applications, five main groups are distinguished: (1) preoperative planning, surgical training and teaching, (2) inert implants, (3) surgical instruments and special equipment associated with the operations, (4) postoperative guides, long-term supports and aids and (5) artificial tissue. The first four of these are already in general use, whereas the last one is still under investigation.
