Description

[0001] Related applications [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 877799, filed July 23, 2019, the entire contents of which are incorporated herein. Background technique [0003] Ballistic gelatin is a type of gelatin specially formulated to simulate the human body and is used in a wide variety of experimental settings, from military and law enforcement to medical professionals. While this type of gelatin has proven successful in the ballistics market due to its bodily-like properties, a wide range of adjustable hardness (by slightly adjusting the ingredients of the formulation), and unmatched optical clarity (For some gels on the market, e.g. Clear Ballistics gels), its prospects for other potential applications such as medical and optics have not been fully explored because its manufacturing process relies on traditional molding methods, which limits The complexity of manufacturable structures, and it is time consuming ...

Problems solved by technology

Although this type of gelatin has proven successful in the ballistics market due to its flesh-like properties, as well as a wide range of adjustable hardness (by slightly adjusting the ingredients of the formulation), and unrivaled optical clarity (For some gels on the market, such as: Clear Ballistics gel), its prospects for other potential applications (such as medical and optics) have not been fully explored, because its manufacturing process relies on traditional molding methods, which limits Complexity of manufacturable structures and time-consuming and expensive iterative design tooling

However, due to its flexibility, it cannot be printed with current 3D printers
