Prints in place without supports on an FDM Printer and should work with any material. I've tested pla and petg. A brim is recommended. Also, if using a bed slinger, it's recommended to slow it down so it doesn't come detached. It is designed to work well with a 0.4 mm nozzle, and it should be fairly easy to print, as long as you have good bed adhesion and enough cooling, insuring that your printer can easily do a forty-five degree overhang.

Your mileage may vary, but on my printer, I've been able to scale it down to 80% without issue. when I tried scaling it down to 60% size the pieces could move but not very well so it didn't fidget well, And I can't recommend it.

Additionally, the heavier it is, the more momentum it has and the more premium it feels. So it's nice to add a thicker infill or more perimeters, especially to the blade (So far, my favorite one is three perimeters, 20% infill in PETG at a 1.5 mm layer height). But it's not a huge deal. They all feel pretty good.
