Special Issue Information

Dear Colleagues,

Although a broad number of medical devices for soft and hard tissue regeneration are already on the market, fundamental biological and medical aspects are still unclear. Moreover, most of these materials still do not possess regenerative capacities comparable to autologous transplants. Thus, it is of great importance to obtain deeper insights in the material-associated biological responses for the understanding of the clinical relevance of a specific biomaterial. Moreover, this knowledge, in concert with new results regarding new biomaterials or biomaterial classes, will lead to improved material development and clinical translation. Nowadays, a large number of preclinical in vitro and in vivo studies, as well as clinical studies, are being conducted to develop new biomaterials, with a focus on new material classes such as biodegradable metals or 3D-printed materials for different clinical applications. Furthermore, it is understood that the interaction of materials with the immune system is of high importance for the biofunctionality of biomaterials.

However, we still require deeper insights into different material-related processes. In this Special Issue, we aim to present new insights into the underlying cellular and molecular interactions of biomaterials for hard and soft tissue regeneration. We invite you to submit studies describing new biological aspects of both new and already available biomaterials, and innovative material-processing techniques related to the healing processes of soft and hard tissues. Contributions in the form of reviews and/or original papers are both welcome.

Abstract
For the extrusion 3D printing process, the printing temperature has a significant impact on the filament formation process because the rheological properties of the printed materials are extremely thermal sensitive, which requires a high temperature control accuracy of the print head.

For the extrusion 3D printing process, the printing temperature has a significant impact on the filament formation process because the rheological properties of the printed materials are extremely thermal sensitive, which requires a high temperature control accuracy of the print head. This paper presents a numerical and experimental investigation on the temperature field of a homemade print head. A finite element simulation model for analyzing the temperature field of the print head was established, by which the temperature distribution inside the print head can be acquired. Moreover, to improve the temperature control accuracy, an improved configuration was proposed, and two schemes were compared. The temperature control error dropped from 28% to 6.2% with the improved print head, which was verified experimentally. Furthermore, printing trials were conducted by the optimized print head. The filament diameter could be regulated by changing the temperature of the print head, which validates the feasibility to control the filament diameter during the extrusion process via temperature regulation.
