Removing the Z axis weakness in parts with advanced slicing

An inherent issue with 3D printing is the lack of strength relative to the Z axis due to inter layer adhesion.  I’ve addressed that in parts I’ve made by trying to orientate that axis in the least impactful way, added holes to allow the use of screws of bolts to hold the Z axis together.  It helps, but I think that two things are coming together that could help make 3D printed objects much less z=axis limited, and allow the maximimazation of materials like CF filled filaments.

One is that the XL allows larger parts to be printed.  The other is more sophisticated slicing options and techniques.

What I’d like to see is the option to take a part and then slice and process it so that it is at least two parts.    Then print it so that when fitted together the Z axis are at the 90 degrees to each other.  So kind of like a laminate or a sheet of plywood with the grain in different directions.  I think some 2k or just some urethane glue to hold them together would make it a solid part.

"orientate" 

Just say "orient" - we've all been there 😛

Understanding what process you are using to fabricate a component should drive how you design it, that will make your life a lot easier. I try to avoid glues if at all possible and keep stresses in the same plane. If I must deal with stresses along multiple planes, I either make an assembly and use screws or another mechanical interface to fasten it, or thicken and fuse the part more effectively when I slice it. Typically fusing the parts better by thickening and slowing the print process down, reducing cooling, reducing layer height and/or increasing nozzle temp for a few layers really helps.

Best of luck! 🙂
