Compared to the P1P, the P1S offers a fully enclosed printing chamber and a more powerful cooling solution, which includes an Auxiliary Part Cooling Fan for cooling prints, a Chamber Regulator Fan to stabilize the inner chamber temperature, and a Control Board Fan to assist in cooling the control board. Furthermore, we have equipped it with an activated carbon filter to provide a solution for printing filaments such as ABS that are prone to emitting odors and harmful gases during the printing process.
