Perimeters/shells not properly fusing - delamination

I come to you all in my time of need, as I have nowhere else to turn. I’ve been a 3D printer for about two years now. I have an Ender 5 Plus. Up to this point, all of my prints were fine straight out of the box; no need to calibrate anything besides…

Why does OpenSCAD fail to cut holes in polygon sides that are exactly the width of the wall?

I'm trying to make a frame for a lithograph that I plan to 3D print for my wife for Mother's Day. I typically will have my differences be exactly the right size (rather than oversizing it for the sake of the preview) because it gives me a good feel…

I want to be able to run my Chiron during night-time, but my neighbours tries to sleep at that time of day. I have put a lot of effort into making the printer silent. The controller-fan and power-supply-fan now run slower and only when needed, I…

Are 3D printers efficient for printing a detailed iris to bypass iris identification system?

A 3D printer can either print layer by layer or carve an object layer by layer to obtain an object. I heard somewhere that 3D printing technology isn't that accurate for printing minute details like fingerprints and iris patterns. Printing an iris…

Z-offset: 0.2 mm, 0.1 mm or the thickness of paper?

So, I'm pretty new to 3D Printing, and to quote Spock from Wrath of Khan I would say "He is intelligent, but not experienced". Now everything I have been reading about Z-offset seems to talk about a 0.2 mm gap and using a piece of paper. Wishing to…
