3D printing-based full-scale human brain for diverse applications

Brain-X 2023 Volume 1, Issue 1, Article e5

Surgery is the most frequent treatment for patients with brain tumors. The construction of full-scale human brain models, which is still challenging to realize via current manufacturing techniques, can effectively train surgeons before brain tumor surgeries. This paper aims to develop a set of three-dimensional (3D) printing approaches to fabricate customized full-scale human brain models for surgery training as well as specialized brain patches for wound healing after surgery. First, a brain patch designed to fit a wound’s shape and size can be easily printed in and collected from a stimuli-responsive yield-stress support bath. Then, an inverse 3D printing strategy,…

Complementary Acoustic Metamaterial for Penetrating Aberration Layers

ACS Applied Materials & Interfaces 2022 Volume 14, Issue 25, Pages 28604-28614

Impedance-matched acoustic materials were developed to improve ultrasound penetration through the aberration layer. The traditional ultrasound layer matching material is called a couplant, which can only enhance ultrasound transmission to soft biological media such as the cartilage and muscle but cannot penetrate hard media such as the bone. Here, we propose a phase-modulated complementary acoustic metamaterial based on the principle of impedance matching, which enables ultrasound to penetrate the bone, and use the equivalent parameter technology of acoustic metamaterials for parameter design. Ultrasonic layer adjustment is performed through 3D printing and corrects bone aberrations. Several configurations were investigated through numerical…

A 3D printed patient specific artificial outer ear model for use in auricle reconstruction surgery: a clinical feasibility study

Transactions on Additive Manufacturing Meets Medicine 2021 Volume 3, Issue 1, Article 505

Auricle reconstruction is a routine surgery in the field of Otolaryngology but the design of the reconstruction is based on the clinicians guess of the correct previous anatomy. Using additive manufacturing processes to build a model the surgeon can refer to may be a good substitute for conventional surgery. The quality of the framework replicating the three-dimensional architecture of the ear and precise sculpting of the anatomical structures are necessary in order to reach a desired outcome. In this work we present the workflow to produce an individualized 3D outer ear model for use in auricle reconstruction surgery and report…
