Turning a 3D print into lead! The first print I work on is a 3D printed air gun bullet, and I used just normal plaster casting to make it. Here's a video of it being shot out of my homemade 'MAS' gun    • 3D Printed Airgun Bullets   The second is a Monitor from the Halo game series, and to make it is just wet it down and threw layer after layer of plaster on it until it had a sizable shell. This one really shows that the casting method can capture some fine detail.

Lead casting can be very dangerous so don't attempt something like this unless you're an adult who knows what you're doing and are willing to accept the consequences of your actions.
