Youtuber “Ordnance Lab“ (also known as Ordnance Lab LLC and holds a Type 10 FFL) published a video showing what they say is the “world’s first 3D printed rocket launcher.” 

“In this video we team up with D&S Creations, who have developed 3D printed rockets and rocket launchers. We test both a smaller caliber rocket and a larger one, along with a prototype for a shaped charge warhead. This is just the start of our working on 3D printed rockets. We have the launch and detonation figured out, now we need to work on getting the accuracy figured out,” Ordnance Lab said in the video’s description. 

One firing test shows a 3D-printed rocket with a shaped charge denoting on a target. The narrator in the video said the “flash powder charge produced a very bright and loud report.”
