Abstract
The proposed lattice structure is designed to simplify the time of long and difficult post-printing process of removing the unused powder or resin by blowing air in the additive manufacturing parts. The designed lattice structure is a ventilated three dimensional structure that includes a plurality of lattice bodies arranged in a first direction, a second direction and a third direction. The first direction, the second direction and the third direction are orthogonal. Each of the lattice body has a hollow structure formed by a shell wall including a first venting hole opening in the first direction and facing the first venting hole of another adjacent lattice body, a second venting hole opening in the second direction and facing the second venting hole of another adjacent lattice body; and a third venting hole opening in the third direction and facing the third venting hole of another adjacent lattice body.
