COVID-19 and a novel initiative to improve safety by 3D printing personal protective equipment parts from computed tomography.

Background: Powered air-purifying respirators are in short supply and can break down with extended use. Replacement parts can become hard to acquire. The aim of this study was to create an innovative quality improvement proof of concept using rapid prototyping.

Randomized Controlled Trial of the Effects of 3D-Printed Models and 3D Ultrasonography on Maternal-Fetal Attachment.

Objective: To determine whether the addition of 3D-printed models improves maternal-fetal attachment in healthy pregnancies more than 3D ultrasonography alone.

Design: Randomized, parallel-group, controlled trial.

Setting: University- and clinic system-affiliated locations in Omaha, Nebraska.
