3D Bioplotter Research Papers

In the field of regenerative medicine and tissue engineering, the use of such materials has been included for a short time, serving not only as a replacement for damaged or missing tissue, but also as a support for the surrounding tissues and cells. Such materials should not only be passively tolerated by the cell, but should also actively promote the growth, differentiation and other processes involved in tissue regeneration. The latest approach is the use and development of bioresorbable and biodegradable polymeric materials. Such materials, with their biocompatibility, degradability and suitable mechanical properties, support the overgrowth of new tissue. The…

Currently, 3D printing is one of the popular technological production methods, mainly because it offers various options that affect the resulting properties of prints. The aim of the presented work is to manufacture a prosthetic finger with a PIP and DIP joint using multi-material 3D printing, which will allow to mimic the flexion of a physiological finger. The subject of this research and testing is the design of a combination of solid and flexible material for a monolithic finger model, which will allow the required bending in selected areas of the print.

Additive manufacturing has a great potential for creating hard tissue substitutes, such as bone and cartilage, or soft tissues, such as vascular and skin grafts. This study is a pilot study for 3D printing of a new material mixture potentially used as a tubular substitute for urethra replacement. This new mixture is a blend of polylactic acid (PLA) and polyhydroxybutyrate (PHB). The basic aspect that affects the 3D printing process is correct material preparation and setting of 3D printer parameters. Selection of material and printing parameters depend on printing technology. The printing technology affects material behavior during printing process. The…
