That’s not the only use of the technique though, and perhaps one of the simplest is to use a 3D-printed mould for casting concrete. It’s what [ArtByAdrock] is doing in their latest video ...

After 3D printing a mold design using an Ultimaker 2 [Matt Borgatti] casts the mold using Smooth-On Mold Star 15 that can withstand heat up to 450 °F (232 °C), which he points out is ideal for ...

One way of doing this is to use rapid prototyping technologies. Rapid prototyping uses three-dimensional (3D) computer aided design to quickly fabricate a part or, alternatively, a sand mold for ...
