In Additive manufacturing (AM), generating filling paths(hatches) from the raw slice contours is an important part of build preparation. With Voxeldance hatch tools, you can generate different filling paths for different zones in the slices of a part.  

  • Hatch for different zones

From the menu, click Prepare > create hatch. The voxeldance hatch command contains all function parameters of generate hatches for the contour filling.

In the process of Additive manufacturing, such as SLA, SLS, and SLM, in order to obtain good parts quality and shorten printing time, different hatching paths and strategies are often needed for different filling areas. So we divide each layer into five types: “Up Skin”, “Inner Skin”, “Down Skin’” “ZConnect Skin” and “Hole/Slot Skin”. They are indicated with blue, grey, red, purple and orange, and can be adjusted by several different parameters and combined as desired.  

  • Generate Border path

The Part Border is a contour that surrounds the fill area, you can define the parameters of the border offsets that have to be generatedfor different zones, e.g. In skin, Up skin, down skin and so on.

Beam compensation: Defines the value for laser spot size compensation in return for radius deviation in build paths.the value for the radius should be in accordance with half the value of the beam diameter.

Offset Number: Defines the number of the border offsets that have to be generated.

Offset Space: Defines the distance between the individual border offsets.

  • Generate Inner hatch paths

For inner hatch of a fill area. You can adjust parameters to generate different hatch pattern.

Hatch distance: Defines the distance between individual hatches. In order to generate a self-contained contour plane, this value should be half the beam diameter at the maximum.

Border space: Defines the distance from the hatches to the boundary of the contours.

Rotate start angle: Determines the initial start angle of hatching in relation to the X-axis. Hatch patterns can be rotated each following slice with a defined increment.

Rotate Rotation Increment: Defines the increment value of the rotation angle between consecutive layers.

Layer1: 30°
Layer2: 105°
Layer3: 180°

Hatch Style: There are three different Hatch Styles available.

  • Single fill: Single Fill Hatch Style generates parallel hatching vectors filling the hatching area.
  • Offset fill: Offset Fill Hatch Style generates hatching vectors in closed polylines offset from the hatching area border.
  • Cross fill: Cross Fill generates two perpendicular sets of parallel hatching vectors filling the hatching area. The two hatching vector sets are scanned successively.

Hatch Sorting: there are two hatch sorting styles available, Zigzag and Block sorting.

Block sorting

Hatch Connect: Joins the transition between the endpoints of two adjacent hatch lines within a hatch block by an additional hatch vector(only work in Block soring style).
