Modification of Additive Technologies for Obtaining Medical Forms

Abstract

This review presents technological approaches to 4-D printing, which are modifications of additive technologies. Showing the distinctive features of this technology from the three-dimensional printing. The use of four-dimensional printing in pharmaceutical technology and advantages over traditional methods of creating dosage forms are described. Demonstrated classification of adaptive materials, the principles of their application and features of printing equipment. Examples of adaptive materials are presented, including smart polymers and stimuli sensitive hydrogels. The advantages of this type of production, its development prospects and technological features of the production of microcapsules, hydrogels and mucoadhesive films of smart polymers by additive printing technology are given.

Application of zirconium in dentistry for creating dental crowns

“…The primary process of digitization takes place by obtaining three-dimensional data through 3D scanning and conventional design in a computer environment. This helps to refine the exact final geometry of 3D models first in a virtual environment and subsequently materialize the samples through 3D printers and CNC machines [20][21][22][23][24][25][26]. The refinement of the many stages and the interaction of the different units, scientific fields and interdisciplinarity in a single optimized system is concluded in the combination of the so-called Dentistry 4.0 similar to Industry 4 [27].…”
