Solid Shell

Description

This is a component that generates shell deposition toolpaths from a closed solid geometry. It allows you to configure detailed settings such as the starting position, spacing, height, and tilting degree of the target planes. If the geometry is large, it can export the operation data by dividing it into partitions.

Input

Name	Type	Description
Geometry	Geometry	Target geometry for slicing. Input Brep or Mesh.
Reference Plane	Plane	Reference plane for slicing. Set identical to the build plate direction. Layers are generated along the Z-axis direction of the plane. Default: WorldXY.
Seams	Curve	Guide curve that determines the starting point (Seam) location of each layer’s outer path. The intersection between the curve and the outer path is set as the layer starting point.
Edges	Curve	Guide curve used to tilt target planes formed around the geometry’s edges along the tangent direction of the edges.
Angle Ranges	Number	Angle Ranges
Multiple	Number	Multiple

Required Parameter

Name	Type	Description
Setback	Number	Inward/outward offset distance of the outer path based on the input geometry boundary (mm).
Outline Shells	Integer	Number of outer paths (shells) to be generated along the outline of the input geometry.
Layer Width	Number	Width of a single deposition path (bead width, mm).
Layer Height	Number	Height of a single deposition layer (layer thickness, mm).
First Layer Height	Number	Height of the first deposition layer in contact with the build plate (mm).
Tolerance	Number	Approximation tolerance for the path.

Name	Type	Description
Tilt Weight	Number	Weight to tilt the target Z-axis toward the surface inclination (overhang) direction in overhang geometries. Used to align the torch/extruder with the geometry’s inclination.
Edge Tilt Weight	Number	Weight to tilt the target toward the tangent direction of the edge in geometries with edges. Edge reference curves use the component’s Edges input.
Edge Tilt Ramp	Number	Distance to blend the Edge Tilt effect (mm). Gradually applies and releases Edge Tilt before and after the edge by this distance to mitigate path movement caused by abrupt edge tangent transitions.
Incremental Tilt Steps	Number	Number of layers (N) to gradually reach the configured Tilt Weight. Applies tilting step-by-step starting from initial layers near the build plate, preventing collisions and excessive robot movement caused by abrupt tilting in initial layers.

Name	Type	Description
Wipe Distance	Number	Nozzle wiping distance. • Positive (+): Proceeds with an overlapping path by this additional distance from the starting point after completing the outer path. • Negative (-): Terminates early before this distance from the end point of the outer path.
Seam Spread	Number	Distributes the seam starting points across N cycles to prevent seams from concentrating at a single location. Shifts path parameters by 1/N per layer and returns to the original position every N layers. • Example: N = 4 → Layer 1 = 0.0, Layer 2 = 0.25, Layer 3 = 0.75, Layer 4 = 0.0 (repeating).
Seam Offset	Integer	Offset to collectively adjust the seam positions of all layers. Uniformly shifts the entire sequence while maintaining the positional relationships between layers established by Seam Spread.

Partition

Name	Type	Description
Part Count	Integer	Number of parts to divide and slice the model into. • 1: Slices the entire model. / • N: Divides the model into N parts for partial slicing.
Part Number	Number	Part number (1 to N) to be sliced among the N divided parts.

Output

Name	Type	Description
Shell ToolPaths	Shell ToolPaths	Generated deposition path data.
Shell Profile	Shell Profile	Reference profile information of the generated outer deposition path.
First Part	Boolean	Flag indicating whether the current Deposition ToolPath is the bottom-most (first) part.
Shell Contours	Curve	Polylines connecting the generated outer deposition paths.
