UK maker Artiz is a spearfishing enthusiast who knows what he needs in order to catch the big one. Because of that, he’s been working for quite some time at refining his efforts in making a 3D printing spear gun and several other components so far. The spear gun was 3D printed using ColorFabb XT-CF20 (20% carbon filament), boasting a 3D scanned handle, metal trigger mechanism, and roller muzzle. Just previous to this, Artiz 3D printed a speargun handle on an Ultimaker 3D printer. Using ABS 3D printing filament, it took 34 hours to print. The experienced 3D printing enthusiast has made numerous other iterations of his spear gun and various components as well, all of which can be seen on his YouTube channel.
