Three-Dimensional Printing in Biomedical Application: A Review Article

Abstract

Tissue engineering is a promising therapeutic strategy, yet it is significantly constrained by the challenges of producing implants with anatomically precise characteristics for defects while also possessing appropriate conductive, inductive, and mechanical properties for the tissue or organ being reconstructed, in addition to facilitating effective local drug delivery.
Three-dimensional printing (3DP), or additive manufacturing (AM), is a contemporary technology for producing three-dimensional physical objects incrementally from a digital model, directly derived from a computer-aided design (CAD) file. This approach is a viable alternative for the production of scaffolds, where implants must possess anatomically precise attributes for defects, such as bone substitutes
This review study explores the intersection of three-dimensional printing (3DP) technology and tissue engineering, highlighting the challenges in creating anatomically precise implants with suitable mechanical, conductive, and inductive properties. It discusses the potential of 3DP as a viable method for producing scaffolds that can effectively support tissue regeneration and facilitate local drug delivery, particularly in the context of bone substitutes.
