The creator highlights that the testing is not exhaustive but aims to provide insights into the material properties of resin prints when contrasted with a common FDM filament. The focus is on material science and practical application through a comparative analysis.
This video tests the ballistic resistance of 2.5-inch thick 6061 aluminum blocks against high-caliber rounds. A .50 BMG API round penetrated the first block and lodged in the second, while an AP round nearly exited the second block. Even powerful .500 S&W Magnum rounds were stopped by the aluminum, demonstrating its surprising durability against firearm projectiles.
