Embodiment Construction
[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0041]A 3D printing adaptive slicing method that retains model features provided by the present invention, such as figure 1 with figure 2 As shown, the party specifically includes the following steps:
[0042] Step 1: According to the actual engineering design, use computer software to establish a three-dimensional model, and perform grid processing on the model to generate STL file data;
[0043] The STL file data includes three-dimensional coordinates of three vertices and unit normal vector data of all triangular faces generated after meshing.
[0044] Step 2: Preprocessing the STL file data of the model; specifically, the following steps are included:
[0045] 1) The user specifies the maximum and minimum layer thickness (l max = 10mm, l min =1mm) and the value of tip height c, such as c=0.8mm;
[0046] 2) Sorting and preprocessi...
