Reinforced 3D printing for biomedical applications

Brilliant blog by Laurie Winkless about 3D printed materials for biomedical applications. Really closely related to the bone cement posts i have been doing!

NO LAB COAT NEEDED

German researchers have demonstrated that the mechanical properties of 3D-printed structures can be improved with the addition of fibre reinforcement.

Since entering the mainstream a few short years ago, 3D printing has grown from strength to strength, with systems now capable of printing everything from 3D chocolate shapes to titanium implants. But the technique’s origins in industrial rapid prototyping have not been forgotten, with companies across the globe using 3D printing to create complex components quickly and reliably.

Research from a team at University Hospital Würzburg in Germany has focused on improving one type of 3D printing – three-dimensional powder printing. Their results, published in Materials Letters 139 (2014) 165–168 (DOI: 10.1016/j.matlet.2014.10.065) show that a range of different short fibres can greatly improve the mechanical robustness of a final printed piece when compared to non-reinforced printed samples.

Three-dimensional powder printing (3DP) is used to create complex 3D…
