3D-Printed Composites: Multiple Applications, Recent Advances, and Emerging Prospects

3D printing technology (3DPT) is presently extensively employed in several areas of R&D. Unfortunately; the practical potential of this potentially revolutionary technology is now constrained by the narrow spectrum of physicochemical properties available in 3D-printed materials. High-performance composites made from many materials, each with its unique features, are becoming more popular as a means to improve and vary the characteristics of standard printing materials. In the past, 3D-printed composites have been employed for a wide range of purposes, including the creation of biological, mechanical, electrical, thermal, and optical enhancements. Rapid prototyping has increased the popularity of 3DP composites because of their ability to create complex geometries at a cheap cost. This study reveals that traditional 3DP materials may be upgraded to produce composites with enhanced biometric, electrical, mechanical, optical, thermal, and other characteristics by using nanoparticles, fibres, other polymers, or a chemical reaction.
