Testing horizontally 3D printed bolts without supports - how strong are these sliced screws?

In one of my experiments I was testing horizontally and vertically 3D printed machine screws or bolts. Result was that horizontally printed bolt is much stronger, but in this case, we need to use supports and sometimes a die tool to clear the thread. Link to that video:    • 3D printing bolt and thread in horizo...   There I got a lot of useful comments, like: Print the bolt in two halves and glue it or use with nut Cut the bolt from one side to have flat surface to start 3D printing Cut the screw from two sides, to have symmetrical load In this video you can see these 3 new type of bolts but for reference I printed vertical and horizontal regular screw. M6, M8 and M10 bolts will be measured for torque, tensile and shear stress.
