From my understanding, parts are strongest when printed laying down when they will be stood up. Basically, load along the layer lines, not against them. However, after doing research to clarify, I have been getting contradicting answers from people on forums, AI, etc all over the place that I have found. I don’t know how this is possible, as it is super confusing, but can someone set me straight here.
As an example, I am looking to print this stand for my computer, 1 front, 1 back, 2 legs connected to each other with a top piece that I am printing separately and screwing in, mostly to avoid so much more material and printing time(top has more depth front to back). I am going to print them in the orientation laying down when it will be stood up in use like this.
It seemed like triangles were a good alternative to gyroid with strength being needing just to bear weight, much less printing time mostly, either seemed like good strength options. Thoughts, please? Thanks.

I did see that and have been reading it and read it regarding this and it seems to say what I felt like is true, but my brain is so scrambled from all of these contradictions, I wanted someone to clarify for me.
What you have there will support a lot of weight. That design’s weak point is when that is bolted to the case if you drag it. The interface between the two parts will want to break far before it would from supporting weight.
If you are unsure of your design the best thing to do is print a small scale model and break it. You will be surprised how little it takes to support a car driving on it.
There is no easy way to say, “this is best”. A table leg can be designed a million ways. The only hard fast rules are prints are best in compression, next best pulling on the layer lines like a belt and lastly pulling the layer lines apart. Depending on the filament type, those can be a wide spread or nearly identical.
