Abstract This paper studies the binder droplet injection process in the 3DP technique. The mathematical model of the binder penetration process for multi-nozzle
and multi-layer in 3DP technique is established, by using the conservation Level
set method. According to the two-dimensional plane model of three-dimensional
spatial structure of sand bed, the construction method of an equivalent cylindrical
mapping infiltration model is proposed to represent the porosity of the model in
the two-dimensional plane, which is exactly the same as that in the three-dimensional
space, as well as closer to the arrangement of the three-dimensional space, and… More >
