Comment 3D Printing is Not Just Glorified Glue Guns (Score 4, Informative) 490
It's sad that 3D printing had become synonymous with FDM or glorified glue guns (GGG). There are lots of different technologies that fall under the umbrella of 3D printing.
Here's a gun that was 3D printed using DMLS (Direct Metal Laser Sintering) for the metal parts and SLS for the grips. It's both durable and viable.
