Klaas Robers wrote:Andrew, how do you think to get an optically flat edge to the 3D-printed slats? Before metalizing they should be optically flat, that is a surface roughness of about 10 nm or better. A used method is to place all slats in the same orientation on a spindle, and then polish the block that you made. But with your positioning stubs it is no more possible to make a polishing block of them. And they should become flat as a mirror.
albertMunich wrote:And the stuff I use (PLA) cannot be polished at all. It just heats up and smears all over the place. A mess! There are metal filled PLA variants, where a certain amount of metallic powder is added to the original mixture. But I have never tried it because it tends to clog up the printer nozzle. You have to have special ones for this purpose. My own printers are the first series Ultimaker brought to market, their newer ones have provisions for changing the nozzle in a few seconds, in mine its a chore and you risk damaging the machine. So I'm not ready to try that.
