The proposed workflow maximizes the combined use of CT imaging and 3D Printing, and shortens the time it takes to design and produce a patient-specific implant. In this research, real-time customization of a patient-specific implant was made possible for the entire process of design and additive manufacturing.
AM presents notable design possibilities. However, creating patient-specific anatomical structures requires unique expertise due to the variety of optimization platforms. Additionally, the design and manufacturing process for complex anatomical structures is computationally demanding. How can these practical obstacles be overcome?
DICOM-to-lattice design methodology
A novel DICOM-to-lattice structure method was introduced in which 2D DICOM cross-sections were converted into periodic lattice structures. Hence, there was no need for 3D reconstruction, manual intervention, data conditioning or smoothing operations. This resulted in highly geometrically accurate and conformal lattice structures produced in less time.
Although these results show a lot of promise, further work needs to be done before the methodology reaches a broad clinical use.
