Adaptive lattice bars

Builds a scaffolding under and around the part and supports it with bars

This is an area-supporting action. It fills the volume underneath supportable surface areas subdivides the determined support into unit cells which are then filled with lattice topology. From the scaffolding thus created, individual bars support the respective downskin clusters. If possible, and enabled, whole groups of eight cells (2×2×2) are collapsed into single cells.

Main parameters

Parameter Description Notes
Description

Holds a text label for the action that remains visible even when the action parameters are collapsed in the script tab

Color

Sets a display color for the support elements generated by this action

Cannot be reverted once changed, only explicitly set to a new color

Cluster

Search parameters for areas of contiguous triangles requiring supports

See Cluster detection reference

Anchors

See Anchors section below

See Anchors
Cell width, Cell height

Sets the size of the smallest cell, and indirectly the angle of diagonal support bars. The ratio of width to height should be kept above a certain value so as to keep the diagonal bars printable.

Adaptive steps

The rule of collapsing multiple fully intact lattice cells into the next larger cell size is applied up to this many times. Note that this is only the permissible maximum. If there aren't enough intact cells in a contiguous 2×2×2 arrangement, no collapsing is performed.

Comparison of adaptation. Three adaptive steps lighten the lattice considerably more than just one step.

Distance part to lattice

This minimum distance is enforced between lattice and part surface when hugging the surface contours with the lattice scaffolding.

Lattice go around the part

If enabled, an additional layer of lattice cells beyond the part circumference is generated to fill even more volume with rigid support but consequently consumes significantly more build space on the platform. This helps with supporting part sections otherwise too far up, or significantly undercut by part structures further down.

Gap between part and lattice

Artificially increases the gap between lattice grid and part surface to prevent intersection even on intricate side walls

Latticing behavior

Controls the expansion and use of additional lattice cells beyond the originally determined volume.

  • Grow at adaptive steps: Permits or generates expansion next to places where adaption collapsed a group of cells into a single cell
  • Grow at platform: Expands the lattice only within the first three unit cell layers on the platform, forming a frustum
  • Constant shape : Permits no expansion at all
Allow lattice on upskin and sidewalls

Permit lattice generation in open or closed cavities where it could not normally grow into and where only regular bars would be generated.

Baseplate for group

Enables or disables group-local baseplate generation

Bars per group

Puts at most this many bars into a group. A group of bars may have a local baseplate.

Anchors

Parameter Description Notes
Anchor distance

Defines the space between two anchor points or bars on the cluster surface. This is independent from the lattice cell size.

Rasterize area, Anchor alignment

Switches between rectangular, hexagonal, or no anchor placement on the cluster surface. This is independent from the lattice cell topology which always has a quadratic cross section.

Contour offset to wall

Anchors keep a distance from a cluster contour that borders a wall (a concave border).

Free contour offset

Anchors keep a distance from a cluster contour that does not border a wall.

Down-oriented points

Puts a dedicated bar at a cluster's lowest point

Corners

Puts dedicated bars into corners of a cluster's contour

Add bars to medial axis

Traces the centerline of narrow cluster passages to ensure good support in places where neither the regular, area-filling pattern, nor the contour-tracing pattern would fit.

Medial axis contour offset

Narrow passages may be at most twice this wide to still receive the medial axis supports.

Borders

Traces the cluster contours with supports

Z-range limitation, Minimal z value, Maximal z value

Places anchors only within this range even when the associated clusters span greater ranges

Single down point tips

Puts a dedicated bar on downward-facing protrusions whose sides would otherwise not qualify for cluster detection. This is off by default.

Sharp edges

Toggle to support down-facing edges with a line of additional bar supports each

Maximum edge angle to XY plane

Specify a threshold angle from the horizontal for the sides of an edge from which it becomes eligible to receive support

Neighbor area angle

Specify a "critical angle" for the surface that itself is not critical but terminates in the sharp edge.

Support properties Baseplate

These local baseplates generate for groups of bars when Groups > Baseplate for group is set to Yes. These baseplates are distinct from Support properties Bar > Pad on platform.

Parameter Explanation Notes
Outer offset

Distance by which the minimum contour formed by the contact points of a group's bars is extended to make the base plate's contour. This is the minimum distance before tapering.

For the Pattern of Point connection net, no offset is generated. Instead this value is used to derive the wall thickness of the point connections, using effectively twice this value.

Maximum height

The base plate's thickness

Taper angle

Applies a taper to the base plate's circumference. Positive angles taper the plate towards the top. Tapering only ever adds onto the contour offset.

  • -60° to 60°
Pattern

A selection of structures applicable to the baseplate

  • Solid: No structure at all
  • Rectangular: Square holes
  • Hexagonal: Hexagonal holes
  • Circular: Circular holes
  • Column: Circular columns
  • Point connection net: Attempts triangulation between the anchors on platform to ensure bars always terminate on solid plate volume without needing to make the entire plate solid
Cell size

Size of the holes for Rectangular and Hexagonal, measured at right angles between wall surfaces, or outer diameter for Circular and Column, respectively

Rectangular, Hexagonal, Circular, Column only

Pattern wall thickness

Thickness of walls between holes, or gap between columns

  • Generates open supports for single beam passes when set to 0, closed or solid supports for contour-and-hatch exposure otherwise
  • Must be >0 for Circular and Column
  • Rectangular, Hexagonal, Circular, Column only
Perimeter wall thickness

Generates a wall along the perimeter of this thickness

  • Generates open supports for single-pass beam exposure when set to 0, closed or solid supports for contour-and-hatch exposure otherwise
  • Rectangular, Hexagonal, Circular, Column only

Polygon corner

Affects triangle resolution of the circular features

Circular, Column only
Minimum pattern area

A filter to help suppress fragments. Holes are suppressed (filled) if area cannot meet minimum fraction

  • Rectangular, Hexagonal, Circular, Column only (ignored for Column)
  • Unavailable when Pattern wall thickness is 0
Minimum structure hatch

A filter to suppress any polygon stretches shorter along the XY plane than the given value.

  • Rectangular, Hexagonal, Circular, Column only (ignored for Column)
  • Unavailable when Pattern wall thickness is >0
