3D-Printed Composite Materials: Innovations in Additive Manufacturing for Custom High-Performance Structures

Abstract

  This research paper focuses on the developments in 3D-printed composite material and its participation in the field of additive manufacturing of high-performance, custom-designed structures. Continuous fiber reinforced composites are widely used and possess desirable properties of light weight, high strength and high design freedom applicable in aerospace, automotive, healthcare and marine sectors. The paper brings into focus the many significant developments in methods of 3D printing and the use of continuous fiber-reinforced materials, topology optimization and multi-physics software for design and manufacturing. Using the results of simulation of manufacturing parameters including layer thickness, fiber orientation, and infill density, this paper reveals that small variations of parameters are critical for high mechanical property values. Also, the prospects of using composites based on 3D printing for various branches of industry are described; the popularity and need for such material increase. The research also discusses future prospects to the field including bio-based composites and application of smart materials and properties such as self-healing and real time monitoring innovations that would improve on the sustainability and efficiency of 3D printed composites.
