I have a 3D print where there are 5 holes with a diameter of 4 mm in a cup, and I would like liquid to flow through all 5 holes at once while slowly draining the cup (by slowly I mean: just take a few seconds and not drain instantly). Therefore the…

What is a good way to estimate the impact on material strength different printing methods will have?

I'm going to 3D print a part that needs to meet certain strength requirements, due to its usages. I know how strong a particular plastic (eg. comrpessive/tensile/shear strength) is when dealt with in a solid chunk, but not when it is 3D printed.…

Specifying Z offset in Marlin firmware

I need to set a Z offset for the Flying bear P902. I calculated the offset (-2.98). But, every time when I try to input this using the LCD screen of my 3D printer, the value jumps to either -2.99 or -2.97. As -2.97 is just a little bit too far from…
