I started 3D printing with Qidi FDM printers because of their high quality, reasonable price and phenomenal customer service.My first resin 3D printer was a phrozen sonic mini. Once I saw how easy and nice resin printing is I was about to purchase Form Labs 3L resin printer. I came across Qidi S-box which 15 Qidis cost as much as 1 Form Labs of similar build size. I have bought 3 S-box's o far and love them to death. My phrozen sonic motor has died within 45 days. Not a single problem running S-box 9 hours/day 5x week. The sonic mini was slightly faster with mono lcd but build quality is not industrial grade like s-box and yield was low.Planning to order more S-boxes soon. Its like the energizer bunny it keeps going and going and going.... Can't wait to see what Qidi comes out with next!
