When molding the standard cylinder parts by using the three dimensional power bonding(3DP)technology,in order to prepare the coating quick drying agent required for the post-processing process of 3DP technology,an experimental scheme was designed using Box-Behnken in response surface methodology,with compressive strength as the indicator,and the optimized ratio scheme was determined.As the post-treatment agent,the effects of penetration parameters(penetration frequency,penetration mode,and penetration interval time)on the compressive properties of 3DP process molded parts were discussed from both micro(SEM and EDS)and macro(compressive strength testing)perspectives.The results indicate that the prepared coating quick drying agent can effectively improve the compressive properties of the molded parts.During infiltration treatment,the compressive properties of the formed part can be effectively improved by using the infiltration form of multiple infiltration and increasing the infiltration interval time step by step.
