In the recently published, ‘ Hydroxyapatite Structures Created by Additive Manufacturing with Extruded Polymer,’ Katherine Vanesa López Ambrosio (School of Advanced Materials Discovery / Colorado State University at Fort Collins ) tackles 3D printed implants for bone regeneration.
.
While surgeons have been using conventional implants with some success, there is always a risk of infection and the potential for lack of compatibility. Costs are high too with traditional techniques as broken bones require implants to guide new growth.

Hierarchical morphology of bone With the use of hydroxyapatite (HAp), researchers see the potential for success but a need to produce synthetic HAp implants. For this study, the team created a hydroxyapatite photo-polymeric resin suitable for 3D printing, and able to produce complex shapes without supports.

Ambrosio and the researchers developed a HAp-based photopolymer slurry for 3D printing Hap green bodies: “The resultant HAp structures maintained their complex details, had […]
