How Strong is 3D Printed Metal?

Updated strength test video here: • 3D Printed Metal vs CN...
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!

Mechanical properties of aluminum and steel are known...I would find intersting too to compare machined and printed samples...and it would be much better if you use standard sample usually adopted in these cases (it is usually a small bar with the terminal part thicker in order to induce the sample to fail in the middle part), with a known cross sectional area. Another thing that I have noticed in your video, in fact, is that no one of the 2 hooks made by pointer metals began to yield before fail. This is an important diffrrence with respect to machined metals, where the piece, before failure has a permanent deformation. This behaviour is and advantage of metals over, for example, composites because it advice you before failing. Composites instead are fragile and fail suddenly. If printed metals should lose this their feature with respect to machined ones, it would be, for me, a big concern.

The slight difference between the stainless steel and aluminium might be because of the melting points. During 3D printing, aluminium might melt more efficiently and bond together more strongly because of its lower melting point.

@@nocturnal0072 316L Ultimate Tensile Strength is 515 MPa while that of AlSi10Mg is at max 450 MPa. That is about 14.5%. The AlSi10Mg though has a higher Yield Strength than 316L. If this were a straight up test of a fixed object it shouldn't matter but we are looking at a complex assembly and the 316L assembly going plastic first could very well have seen loading on individual areas of the assembly increase on the 316L as others went plastic. Also, as said, the 316L "looks" like it may not be perfectly sintered but we are looking at something already torn apart. Bottom line, without testing a simple test part lacking moving features and assembly it is very hard to make a direct comparison.

The cost difference for aluminum and SS makes the slightly lower strength of the aluminum compelling for the 3D printed versions. I think the SS would be lots stronger except that the melting point is much higher and that was probably making for poorer bonding of the metal powder. If these clips were made from actual solid aluminum or SS I think the strength would be much better. You can see the porosity of the metals...that's going to make 3D printing weaker.

To me the aluminium was superior as the jaws didn’t fail in any way. The stainless jaws began to fail at 884kg. The aluminium clip failed only a little lower than this, but not the jaws, which looked good. The way the aluminium clip did break, at the bottom, I believe a couple more stainless screws low down would add significant strength and potentially outperform the stainless steel clip. Of course just a little more force could make all the difference, but unless tested we won’t know.

Hey, blacksmith here! You know this new way of making metal parts reminds me of the old ways, in the sense that before mass melting furnaces were a thing, people would process iron trough forge welding sometimes very small pieces together (a bit like the Japanese and the tamagahane). So welding something together will get you to good results, but modern homogenous steels are still superior tho. I think a good forge welding heat forging would help his 3d printed parts actually stick together more into a solid piece. Also the grains look disgusting... His metal parts definitely need tempering cycles

A few issues I noticed. The stainless steel wasn't tempered properly. The clip you designed is ok but consider the bottom hole it is made of two parts that are pulled on unevenly by the test rig. That isn't a problem with the test rig but the clip design. The hole edges need to be rounded over also it would help if there was a bolt or two ensuring the pressure between the two sides there remains the same.

Report Sxx ~ ((load at fracture)/(area of fracture)). Expect perhaps max of annealed 6061-0 (Sy~8ksi, Sult~18ksi) or whatever the basic Al alloy suggests. If lower, this gives an idea of loss by 3D print on axial, at least in this case. A cantilever test, or a perpendicular pull would be interesting to also involve the plane-to-plane bond. All in all, we've a strange dichotomy at work, with CMTR's & V&P inspection on traditional, but folks pushing for allowed metal print use in similar higher-QA applications, while a-s-s-u-m-i-n-g handbook values, isotropy, and puzzled looks when reminded of an often near-100% welded part without weld inspection. IMO, as yet, 3D print is most often analogous to in-to-near complete sinter, rather uncontrolled (at present), and of most use to low-stress (& smaller) parts. Perhaps with better control, might come to use low-end bulk properties in FEA or hand calcs but, even there, you've usually a in-plane & orthog-plane layering issue plus shape-& order-of-bond issues. I've reservations, at least 'as yet'.

Interesting project. The steel held up to 1984.16 pounds and the aluminum held up to 1823.22 pounds. That is impressive to me. It could be use to hang bicycles up in garage and things like that.

Since steel has a higher melting point, it is possible that the powder sintered worse than aluminum during manufacture. Maybe Leather didn't have enough power to melt enough. But perhaps there are some limitations or physical phenomena that do not allow creating a stronger part without losing geometry, for example, or gases or oxides are formed that make the structure porous, I don’t know. I'm not an expert - I can only speculate.

Realy intresting video ! But for PLA it look like (3:58 ) it was not 100% infill .. this is not fair in my point of view ...

You should do a video comparing the metal prints to billet milled

3d printed metal isnt the same as forged metal because it has a very loose grain structure compared to the tight compressed grain youd get from forging steel. Also with forged metal you can temper and harden the metal to the desired strength so it's just vastly superior.
