Application of Novel Polymeric Materials Supporting 3D Printing Technology in the Development of Anatomical Models and Regenerative Medicine

There are various combinations of 3D printing technology and medical study process. The aim of this study was to summarize our first experience on 3D printing and outline how 3D printed models can be successfully used in Human Anatomy modern teaching and learning. In 2018 autumn semester, together with traditional methods, a three-dimensional (3D) printing has been introduced into Human Anatomy curriculum at Department of Morphology. In practical classes 39 groups of students from Faculty of Medicine 1st year together with 3 tutors used 3 different open source softwares to create anatomical models and prepared them for printing process. All anatomical models were produced using an FDM 3D printer, a Prusa i3 MK2 (Prusa Research). As methods for data collection were used our observational notes during teaching and learning, analysis of discussions between tutors and students, comments on the preparing and usability of the created and printed models. 3D printing technology offered students a powerful tool for their teaching, learning and creativity, provided possibility to show human body structures or variations. Presented data offered valuable information about current situation and these results were suitable for the further development of the Human Anatomy study course.

The Moment

The paper presents the application of an unconventional method of manufacturing bearing sleeves as well as the carrying out of preliminary research in which the manufactured components were used on a real object. Additive manufacturing methods are increasingly being used, which leads to the rapid development of technologies and their applications. The MultiJet Printing technology was used in the research, which allows precise 3D printing of sleeves made of polymeric materials. The first part of the article deals with the selected manufacturing method and the preparation of a model. The study aimed at evaluating the usefulness of bearings manufactured using the 3D printing technology to support slow-speed rotors. The preliminary research described focuses on the study of operating parameters such as the moment of friction and the bearing node temperature as a function of rotational speed during operation. Experimental tests were carried out at low rotational speeds. This paper presents and determines the scope of the application of bearings manufactured using 3D printing technology.

3D Printing Technology

Aligned topography and biomolecular gradients exist in various native tissues and play pivotal roles in a set of biological processes. Scaffolds that recapitulate the complex structure and microenvironment show great potential in promoting tissue regeneration and repair. We begin with a discussion on the fabrication of aligned scaffolds, followed by how biomolecular gradients can be immobilized on aligned scaffolds. In particular, we emphasize how electrospinning, freeze drying, and 3D printing technology can accomplish aligned topography and biomolecular gradients flexibly and robustly. We then highlight several applications of aligned scaffolds and biomolecular gradients in regenerative medicine including nerve, tendon/ligament, and tendon/ligament-to-bone insertion regeneration. Finally, we finish with conclusions and future perspectives on the use of aligned scaffolds with biomolecular gradients in regenerative medicine.
