“…Too low a saturation level would render the part insufficient strength, while too high could jeopardize the part dimension with unwanted powder stuck on it. Curing time and temperature are other factors to be optimized dependent on the binder property, where the flexural strength of the cured green part is commonly measured for the evaluation of curing quality [69,70]. As for the densification of BJ3DP parts via sintering, multiple factors play a role in the sintering kinetics, including temperature, duration, heating rate, furnace environment, material composition, green density, powder shape and size distribution, etc [52,[71][72][73].…”
