I wanted to hear some opinions/experiences on printing structural shapes. So far, I have simply skipped printing structural shapes. I used square posts for my dust collector model and...it looks good! I was surprised at how it looked when I got it assembled. I'm sticking with it. But I don't think I can skip it on the buildings I'll need to build.

I know there are extruded shapes but I need a style of column that I haven't found. I only know of Plastruct so maybe somebody knows of another company that makes columns for mills that support horizontal I beams for a crane. They have a cut out in them.

As far as FDM printers go, I tried printing a complete column vertically and that didn't go so well. After about 8", the column flexed too much and I ended printing an ugly helix (which was cool!). So I could try splitting the piece across the web and then gluing it together. I figure that would work.

I assume a resin printer can print a beautiful column because there's no physical contact. But I'm stuck in FDM land for the time being.

What have you guys tried?

if Plastruct makes it i dont print it.

However, if you have an .STL file  sent it to me or a drawing with dimensions (decimal preferred).

An 8" column/beam printed vertically  could take 18  hours to print on my FormLabs 3 printer printed on a slight diagonal since 7.25 inches is the max vertical..

I'd suggest two(2) 4" columns that can be fitted together.

Plastruct makes 99% of what I need. I did notice a bit ago that the structural shapes section goes further than what I thought so now I need to go back and make sure I didn't miss it. I will take you up on that offer if you don't mind a long print.

Dividing the column is pretty much the only way I see an FDM doing this job well. I'm glad to see someone using it in practice. I'll probably make myself a little jig to assemble columns/I beams if I go this route. That way I can clamp them good and tight.
