FFF Print Settings Reference

There are a number of print settings available to define your FFF machine. These settings can be saved to a profile for future use.

Print Settings

The print settings are accessed using the Print Settings button.

After you define the print settings, you can add them to a custom profile. You can also remove an existing custom profile, export a profile, import a previously defined profile, or rename a custom profile.

Basic Settings

  • Layer height: Thickness of each deposited layer (mm).
  • Num. perimeters: Maximum number of shells to use for the exterior skin of the part.
  • Sparse infill density: Density of the infill material.
  • Sparse infill pattern: The pattern of the infill material of the print. Choose between a rectilinear or honeycomb infill pattern.
  • Enable raft: If enabled, several coarse layers of material are placed below the part to help increase adhesion and reduce warping.
  • Bed size: Specify the X, Y, and Z dimensions (mm) of the build area.
  • Bed offset: Specify any X, Y, or Z offset (mm) to be applied to the toolpaths.
    Note: Toolpaths are initially created with X=0, Y=0, and Z=0 set to the center of the build plate. If a printer defines its origin at a different location, any necessary offsets may be applied there.
  • Home position: Specify the X, Y, and Z coordinates (mm) for the home position of the extruder.
  • Park position: Specify the X, Y, and Z coordinates (mm) for the park position of the extruder.

Support Settings

  • Support enabled: Enable/disable generation of structures to support parts of the model which have overhangs. Without these structures, such parts would collapse during printing.
  • Overhang angle: Angle threshold (in degrees). Any face whose angle exceeds this threshold will have supports generated to support it.
  • Shell outer offset ratio: Distance to offset the outer support wall for an overhang perimeter. Distance is driven as a ratio of the extrusion width.
  • Shell inner offset ratio: Distance to offset the inner support wall for an overhang perimeter. Distance is driven as a ratio of the extrusion width.
  • Seam width: Width of the seam where the support bonds with the part.
  • Bridge length: Maximum allowable length of a bridging extrusion, before an additional support column must be inserted.
  • Object Z-bump: Distance to move up in Z when printing support paths over the object. Increasing this value reduces the bond between the part and support, which aids in remove of support.
  • Infill Z-bump: Distance to move up in Z when printing infill paths over support. Increasing this value reduces the bond between the part and support, which aids in remove of support.
  • Infill anchor: Distance to maintain final Z position before printing part above the outer shell support.
  • Supported anchor Z-bump: How far above the anchored support the actual part will float.
  • Supported perimeter Z-bump: How far above the support shell the perimeter will float.
  • Extrusion width mult. structure: What extrusion rate should the support structures have. This value is a ratio of the effective extrusion width.

Extruder Settings

  • Extruder temperature: The temperature of the extruder when printing.
  • Build surface temperature: The temperature of the build surface when printing.
  • Filament diameter: The diameter of the filament to be printed.
  • Extruder retract length: The amount to pull filament backwards, out of the nozzle, when a retraction is necessary.
  • Extruder retract speed: The speed to pull filament backwards, out of the nozzle, when a retraction is necessary.

Infill Settings

  • Sparse infill angle: Rotation transform to be applied to all infill patterns.
  • Solid infill angle: Rotation transform to be applied to all sollidfill patterns.
  • Single pass connect: Naïve slicing option in order to enable faster toolpath generation.

Extrusion Settings

  • Perimeter overlap ratio: Ratio overlap of adjacent perimeters.
  • Perimeter-infill overlap ratio: Ratio of extrusion width to amount that the inner-most perimeter will make contact with infill.
  • Layer 1 extrusion width multiplier: Multiply all extrusion widths by this amount when on the first layer.
  • Extrusion width multiplier: Multiply all extrusion widths by this amount.
  • Draw inner perimeters first: If selected, perimeters will start from the inside and work out. If not selected, the perimeters will start from the outside and work inward.
  • Extrusion width: The desired width of a single extrusion.

Layer Settings

  • Layer 1 height: The height of the first layer.
  • Num. top shells: Number of layers to print solid when printing the top of an object.
  • Num. bottom shells: Number of layers to print solid when printing the bottom of an object.
  • Randomize perimeter start points: Randomize perimeter start points.

Speed Settings

  • Internal perimeter speed: Speed to print all non-external perimeters.
  • External perimeter speed: Speed to print the external-facing perimeter.
  • Sparse infill speed: Speed when printing sparse infill.
  • Solid infill speed: Speed when printing solid infill.
  • Travel speed: Speed at which the print head moves while it is not extruding material.
  • Layer 1 speed multiplier: Speed multiplier to be applied to all movements made when printing the first layer.
  • Raft layer 1 speed: Speed when printing the first layer of a raft.
  • Raft layers 2+ speed: Speed when printing any layers of the rafter after the first layer.
  • Bridge speed: Speed when printing a bridge.
  • Support speed: Speed when printing support material.

Cooling Settings

  • Minimum extrusion speed: Minimum allowed extrusion speed.
  • Num. layers fan disabled: The fan is disabled for the first <n> layers to aid build plate adhesion.
  • Min. time per layer: A minimum allowed time, per layer ensures providing ample time for each layer to cool. This value is overridden by the minimum extrusion speed.
  • Fan enabled: Enable/disable generation of fan enable/disable gcode commands.

Skirt/brim Settings

  • Num. skirt/brim loops: Number of skirt/brim loops around an object.
  • Skirt/brim distance: Distance the skirt/brim will be offset from the part.
  • Skirt/brim min. length: Minimum length of extrusion per layer to use for skirt/brim. Add loops until this length is reached.

G-code Settings

  • Start G-code: G-code to be inserted at the beginning of the file.
  • End G-code: G-code to be inserted at the end of the file.
  • Layer change G-code: G-code to be inserted between each layer.
  • Verbose G-code: Enable/disable comments in the g-code.

Raft Settings

  • Raft base fill density: Density of the first layer of the raft.
  • Raft base height: Layer height of the first layer of the raft.
  • Raft base ext. with mult.: Apply this multiplier value to the original extrusion width value.
  • Raft interface infill density: The infill amount of the layer(s) between the raft's first layer and top layers.
  • Num. raft interface layers: Number of raft interface layers. The interface is the middle section of the raft.
  • Raft interface height: The layer height of the interface layer.
  • Raft border distance: The amount to offset the raft from the part.
  • Num. raft surface layers: The number of surface layers on the raft. The surface layer(s) are the top portion of the raft.
  • Raft surface height: The layer height for each raft surface layer.
  • Raft Z-bump: The distance the actual part is displaced from the raft. This can be used to tune the part's adhesion to the raft.
  • Zigzag raft base: Enable/disable a zigzag pattern on the base layer of the raft.
  • Raft base run distance: Distance the raft base (first layer) will extrude before breaking into zigzag sections.
  • Raft base turn distance: Distance the raft base will run after breaking into zigzag sections.
  • Raft base gap distance: Distance between sections of a zigzag raft.

Bridging Settings

  • Bridging enabled: Enable/disable bridging.
  • Bridge extension with mult.: Extrusion multiplier value for when extruding a bridging feature.
  • Bridge max. length: Minimum bridging feature length. Below this value, any extrusions will not be treated as bridges.

Prime Settings

  • Prime extrusion multiplier: Extrusion multiplier when priming the nozzle.
  • Nozzle priming enabled: Enable/disable priming at the beginning of a print.

Version Settings

  • Engine version: The version of the Torpedo FFF engine.
