Is an UNfilled 3D Print Stronger than an INfilled 3D Print?

Tell me if you think this option should be added to the slicer!

This is an idea I had a long time ago and really it's not my idea, it's taking what we already know from the structural steel industry and finding a way to apply it to 3D printing. With printing we have the advantage of being able to make any shape we'd like, with steel, it's possible, but hard to do on a big scale. I beams are another good example of how to make the ideal beams with minimum deflection and max load capacity. These are great if you understand the direction of loading well, if not, a square tube is another great option and it's most similar to what we've done here in this set of tests.

I added in the Black Basic PETG because I was curious, but it was not charted with the rest since it was not part of the main experiment. It is a good clue to the performance differences between the different materials and how layer adhesion and the flexibility of the different materials affects their performance.

#1 Core XY - Best bang-for-buck
QIDI Q1 Pro - https://qidi3d.com/products/q1-pro?sc...
This printer isn't as full featured as the X1C, but it is very capable and very precise. It also has a heated chamber and can reach higher hot end temps.

#2 Core XY - Most features with great results but Pricey $$
