Zusammenfassung:	The utility model relates to an anti-blocking Z-axis balancing device and a 3D printer with the same, and solves the problem that a Z-axis platform is easy to block due to the fact that a screw rod isnot parallel to a sliding rail in the Z-axis direction of an existing 3D printer. The device comprises a screw rod and a sliding rail which are vertically arranged, the screw rod is sleeved with a screw sleeve in a threaded mode, the outer side of the screw sleeve is sleeved with a connecting block, a connecting piece is connected between the screw rod and the sliding rail, a balance block is arranged on the connecting piece, a first through hole is formed in the connecting piece, and a second through hole is formed in the balance block; the thread sleeve is arranged in the first through holeand the second through hole in a penetrating mode, gaps are formed between the thread sleeve and the inner wall of the first through hole and between the thread sleeve and the inner wall of the second through hole, a balance
