I’m printing small keystems for an old keyboard which I designed. They are rather small - 20 mm high and about 7 mm in diameter. Since I need a lot, I tried to print 50 on my print bed. This inevitably smeared PLA everywhere.
I dialed the number back, succeeding in getting consistent quality at 10 pieces. I bumped it up to 20 and all pieces printed, but the quality degraded - specifically the layers shifted up the pieces, creating a rougher look and increasing the outside diameter enough to render them useless.
I’m guessing this is a common phenomenon with 3D printers. Any way I can combat it? Or am I stuck to printing only really small batches at a time?
