Application of 3D printing technology for medical implants: a state-of-the-art review

ABSTRACT

The additive manufacturing technology is best suited for the use of nanocomposite materials. They have the remarkable capacity to adapt to changing conditions by altering their physical, chemical, and biological characteristics. Additive manufacturing (AM) creates three-dimensional objects by layering materials together. Nanocomposite materials have a greater surface to volume ratio in the reinforced phase, making them suitable for AM. Polymer nanocomposites, nylon-12, nylon-6, graphene nanoplates, polyamide 12 are some materials for AM enhancing the product quality. TiC/Ti nanocomposite, Ceramic-based nanocomposite, Polymer/carbon nano tube nanocomposites, PA6/Hectorite clay nanocomposites are being discussed in briefly. SLA, 3DP, SLS, EP, FDM, etc. are the techniques of for manufacturing of products in additive manufacturing. Fundamentals of seven AM processes, its mechanical properties are discussed in this chapter. This chapter also goes through a few of the flaws. The use of nanomaterials in the area of AM has a lot of promise, and there is a growing interest among academics and industry to look for new advancements. New creative nanomaterials and AM techniques are still being researched, and the collaborative energy between these two fascinating areas will shape the future of AM and nanocomposites.
