Special Issue Information

Dear Colleagues, 

Polymeric biomaterials comprising synthetic and natural polymers have been extensively used in medical and surgical applications. Examples include implantable prostheses, tissue engineering, and regenerative medicine. Their versatility in terms of their mechanical, chemical, and physical properties has increased their popularity in medical treatment. In the biomedical field, three-dimensional (3D) printing allows on-demand creation of custom-made personalized prostheses, scaffolds, and drug delivery devices with high structural accuracy. Recent advancements in 3D printing in combination with polymeric biomaterial application have widened the opportunity to develop customizable medical treatments. 

The purpose of this Special Issue on “Polymeric Biomaterials for 3D Printing” is to bring together all recent advances in this field to enrich young scientific minds. Herein, we aim to publish original research articles and reviews highlighting the design and development of 3D-printable polymeric biomaterials, including synthetic polymers and biopolymers such as protein and polysaccharide. We are also interested in 3D printable hydrogels, the development of bio-inks, and a deeper understanding of their properties and applications. We hope that this Special Issue will inspire and contribute innovative research in this emerging field.

Abstract
New additive manufacturing techniques, such as melting electro-writing (MEW) or near-field electrospinning (NFES), are now used to include microfibers inside 3D printed scaffolds as FDM printers present a limited resolution in the XY axis, not making it easy to go under 100 µm [...] Read more.
New additive manufacturing techniques, such as melting electro-writing (MEW) or near-field electrospinning (NFES), are now used to include microfibers inside 3D printed scaffolds as FDM printers present a limited resolution in the XY axis, not making it easy to go under 100 µm without dealing with nozzle troubles. This work studies the possibility of creating reproducible microscopic internal fibers inside scaffolds printed by standard 3D printing. For this purpose, novel algorithms generating deposition routines (G-code) based on primitive geometrical figures were created by python scripts, modifying basic deposition conditions such as temperature, speed, or material flow. To evaluate the influence of these printing conditions on the creation of internal patterns at the microscopic level, an optical analysis of the printed scaffolds was carried out using a digital microscope and subsequent image analysis with ImageJ software. To conclude, the formation of heterogeneously shaped microfilaments (48 ± 12 µm, mean ± S.D.) was achieved in a standard FDM 3D Printer with the strategies developed in this work, and it was found that the optimum conditions for obtaining such microfibers were high speeds and a reduced extrusion multiplier.
