Special Issue Information

Dear Colleagues,

This Special Issue, titled “Smart Materials, Intelligent Structures and Innovative Applications of 3D Printing and Bioprinting Methods”, aims to publish high-quality and original research papers (papers that have not been published elsewhere) based on innovative research that are mainly related to the evolution and trends of 3D printing methods, with applicability in large areas that are related to medical applications.

The main aim of this Special Issue of Materials is to explore new types of materials that are conceived, developed and suitable to be used for different types of 3D printing technologies. Either we refer to metallic materials, polymers, ceramic materials or composites or refer to specific methods that are used for widening the area of materials (by mixing hybrid materials, coatings, immersing, etc.). The use of these types of materials by using 3D printing methods or bio-printing is aimed to be presented through the papers that will be published in this Special Issue.

Developing different types of lattice structures to decrease the weight of parts by topological optimization (with applicability in the aerospace or automotive industry) or to stimulate the osseo-conductivity of different types of implants made by 3D printing technologies (with applicability in the medical field) are the results that aim to be reached by following different characterization procedures (e.g., mechanical testing, SEM, TEM, AFM, EDX analyses, etc.) in this Special Issue.

In terms of the applicability of the methods, any application that is linked to medical models (skull implant, hip implant, vertebral implant, bone reconstruction, skin, tissue, vessels, muscles, organs, etc.) are more than welcome to be included in the Special Issue.

The main topics of interest encompass  scientific contributions related to the following research areas:

  • New types of materials suitable for 3D printing technologies;
  • Design of new structures and topological optimization;
  • Modeling and simulation of processes or newly developed products;
  • Additive manufacturing, 3D printing and bio-printing methods; Mechanical testing of parts made using 3D printing technologies;
  • Material characterization methods for newly developed materials.

It is our pleasure to invite researchers, scientists, surgeons and professionals from academic institutions and research centers from around the world to submit their contributions to this Special Issue.

The evolution of thermoplastic materials has played a critical role in advancing high-speed Fused Filament Fabrication (FFF) and Fused Deposition Modeling (FDM) 3D printing technologies. This study explores the performance and challenges associated with next-generation thermoplastics specifically designed for high-speed printing, such as high-speed PLA, ABS, and PETG, in comparison to conventional materials. A systematic analysis was conducted to evaluate the key parameters, including the mechanical properties, layer adhesion, surface finish, and dimensional accuracy, under varying high-speed printing conditions. The results reveal that high-speed thermoplastics, when coupled with advanced hardware and optimized motion control systems, achieve up to a 70% reduction in printing time without significant trade-offs in mechanical integrity or precision. Additionally, the study identifies challenges, such as increased thermal stresses, warping, and the need for precise cooling strategies, which can impact material performance at elevated speeds. Opportunities for future development are also discussed, including the design of novel polymer formulations and hardware innovations to further enhance the reliability and scalability of high-speed FFF/FDM printing. This work underscores the potential of adopting such advanced thermoplastic materials in the high-speed 3D printing era and highlights the critical interplay between material science and hardware engineering for achieving next-generation manufacturing capabilities.
