How Strong is 3D Printed Metal?

A little while back I designed a snap close connector (STL link below) and some of you wanted to know just how strong it was. But I also wanted to find out how strong the design could be if it was 3D printed in metal. PCBWay were kind enough to provide me with aluminium (AlSi10Mg) and stainless steel (316L) 3D printing services. Using their selective laser melting (SLM) 3D printers they printed some amazing parts that I assembled into my snap clips (frog). Next, I needed to build a tensile strength testing rig to test these things - and it was going to have to be strong! So I built a 1 tonne tensile testing machine that uses a bottle jack to tension the parts. The results were a little surprising!
