About Us

Built in Orange County. Shipped everywhere.

Companies like Xometry, CraftCloud, and Protolabs all outsource their part making, often time leading to weeks long lead times, and no control or interaction with the supplier. Mithril Plastics is a rapid-prototyping and low-volume production shop serving America’s industrial and manufacturing sectors. We run printers, molds, and casting lines under one roof.
