Infill
Infill
| Parameter | Parameter Name | Parameter CLI flag | Description | Default Value |
|---|---|---|---|---|
| Sparse Infill % | fill_density | --fill-density | Density of internal infill, expressed in the range 0% - 100%. Set 0 to remove any sparse infill. Note that using a value of 100% won't change the type of infill from sparse to solid. If you want only solid infill, you can set the 'Solid infill every X layers' (solid_infill_every_layers) to 1 instead. (% ) | default: 18% |
| Sparse Infill pattern | fill_pattern | --fill-pattern | Fill pattern for general low-density infill. If you want an 'aligned' pattern, set 90° to the fill angle increment setting. (rectilinear, alignedrectilinear, monotonic, grid, triangles, stars, cubic, line, concentric, honeycomb, 3dhoneycomb, gyroid, hilbertcurve, archimedeanchords, octagramspiral, scatteredrectilinear, adaptivecubic, supportcubic, lightning) | default: stars |
| Sparse Infill Connected | infill_connection | --infill-connection | Give to the infill algorithm if the infill needs to be connected, and on which perimeters Can be useful for art or with high infill/perimeter overlap. The result may vary between infill types. (connected, holes, outershell, notconnected) | default: connected |
| Sparse Infill Connection Length | infill_anchor_max | --infill-anchor-max | Connect an infill line to an internal perimeter with a short segment of an additional perimeter. If expressed as percentage (example: 15%) it is calculated over infill extrusion width. Slic3r tries to connect two close infill lines to a short perimeter segment. If no such perimeter segment shorter than this parameter is found, the infill line is connected to a perimeter segment at just one side and the length of the perimeter segment taken is limited to infill_anchor, but no longer than this parameter. If set to 0, the old algorithm for infill connection will be used, it should create the same result as with 1000 & 0. (mm or %) | default: 0 |
| Sparse Infill Perimeter anchor | infill_anchor | --infill-anchor | Connect an infill line to an internal perimeter with a short segment of an additional perimeter. If expressed as percentage (example: 15%) it is calculated over infill extrusion width. Slic3r tries to connect two close infill lines to a short perimeter segment. If no such perimeter segment shorter than infill_anchor_max is found, the infill line is connected to a perimeter segment at just one side and the length of the perimeter segment taken is limited to this parameter, but no longer than anchor_length_max. Set this parameter to zero to disable anchoring perimeters connected to a single infill line. (mm or %) | default: 600% |
| Solid Infill pattern | solid_fill_pattern | --solid-fill-pattern | Fill pattern for solid (internal) infill. This only affects the solid not-visible layers. You should use rectilinear in most cases. You can try ironing for translucent material. Rectilinear (filled) replaces zig-zag patterns by a single big line & is more efficient for filling little spaces. If you want an 'aligned' pattern, set 90° to the fill angle increment setting. (rectilinear, rectilineargapfill, monotonic, monotonicgapfill, monotoniclines, alignedrectilinear, concentric, concentricgapfill, hilbertcurve, archimedeanchords, octagramspiral, smooth) | default: rectilineargapfill |
| Solid Infill connection | infill_connection_solid | --infill-connection-solid | Give to the infill algorithm if the infill needs to be connected, and on which perimeters Can be useful for art or with high infill/perimeter overlap. The result may vary between infill types. (connected, holes, outershell, notconnected) | default: connected |
| Top Infill pattern | top_fill_pattern | --top-fill-pattern | Fill pattern for top infill. This only affects the top visible layer, and not its adjacent solid shells. If you want an 'aligned' pattern, set 90° to the fill angle increment setting. (rectilinear, monotonic, monotonicgapfill, monotoniclines, alignedrectilinear, concentric, concentricgapfill, hilbertcurve, archimedeanchords, octagramspiral, sawtooth, smooth) | default: monotonic |
| Top Infill connection | infill_connection_top | --infill-connection-top | -Give to the infill algorithm if the infill needs to be connected, and on which perimeters Can be useful for art or with high infill/perimeter overlap. The result may vary between infill types. (connected, holes, outershell, notconnected) | default: connected |
| Bottom Infill pattern | bottom_fill_pattern | --bottom-fill-pattern | Fill pattern for bottom infill. This only affects the bottom visible layer, and not its adjacent solid shells. If you want an 'aligned' pattern, set 90° to the fill angle increment setting. (rectilinear, monotonic, monotonicgapfill, monotoniclines, alignedrectilinear, concentric, concentricgapfill, hilbertcurve, archimedeanchords, octagramspiral, smooth) | default: monotonic |
| Bottom Infill connection | infill_connection_bottom | --infill-connection-bottom | Give to the infill algorithm if the infill needs to be connected, and on which perimeters Can be useful for art or with high infill/perimeter overlap. The result may vary between infill types. (connected, holes, outershell, notconnected) | default: connected |
| Bridge Infill Pattern | bridge_fill_pattern | --bridge-fill-pattern | Fill pattern for bridges and internal bridge infill. (rectilinear, monotonic) | default: rectilinear |
| Bridge Infill connection | infill_connection_bridge | --infill-connection-bridge | Give to the bridge infill algorithm if the infill needs to be connected, and on which perimeters. Can be useful to disconnect to reduce a little bit the pressure buildup when going over the bridge's anchors. (connected, holes, outershell, notconnected) | default: notconnected |
Reducing printing time
| Parameter | Parameter Name | Parameter CLI flag | Description | Default Value |
|---|---|---|---|---|
| Combine infill every | infill_every_layers | --infill-every-layers | This feature allows you to combine infill and speed up your print by extruding thicker infill layers while preserving thin perimeters, thus accuracy. (layers) | default: 1 |
| Supporting dense layer | infill_dense | --infill-dense | Enables the creation of a support layer under the first solid layer. This allowsyou to use a lower infill ratio without compromising the top quality. The dense infill is laid out with a 50% infill density. | default: false |
| Supporting dense layer algorithm | infill_dense_algo | --infill-dense-algo | Choose the way the dense layer is laid out. The automatic option lets it try to draw the smallest surface with only strait lines inside the sparse infill. The Anchored option just slightly enlarges (by 'Default infill margin') the surfaces that need a better support. (automatic, autonotfull, autosmall, autoenlarged, enlarged) | default: autoenlarged |
| Extends internal bridge to infill | internal_bridge_expansion | --internal-bridge-expansion | When creating internal bridges, extends the line to the nearest internal line it can use to support itself. This way, it can avoid curling up as when bridges lines ends over a void. | default: true |
Infill angle
| Parameter | Parameter Name | Parameter CLI flag | Description | Default Value |
|---|---|---|---|---|
| Angle - Fill | fill_angle | --fill-angle | Default base angle for infill orientation. Cross-hatching will be applied to this. Bridges will be infilled using the best direction Slic3r can detect, so this setting does not affect them. (°) | default: 45 |
| Angle - Bridging | bridge_angle | --bridge-angle | Bridging angle override. If disabled, the bridging angle will be calculated automatically. Otherwise the provided angle will be used for all bridges.Note: 180° is the same as zero angle. (°) | default: 0 |
| Modifiers - Increment | fill_angle_increment | --fill-angle-increment | Add this angle each layer to the base angle for infill. May be useful for art, or to be sure to hit every object's feature even with very low infill. Still experimental, tell me what makes it useful, or the problems that arise using it. (°) | default: 0 |
| Modifiers - Alternative Fill Angle | --fill-angle-cross | --fill-angle-cross | It's better for some infill like rectilinear to rotate 90° each layer. If this setting is deactivated, they won't do that anymore. | default: true |
| Modifiers - Rotate with object | fill_angle_follow_model | --fill-angle-follow-model | If your object has a z-rotation, then the infill will also be rotated by this value. | default: false |
| Fill angle template | fill_angle_template | --fill-angle-template | This define the succetion of infill angle. When defined, it replaces the fill_angle, and there won't be any extra 90° for each layer added, but the fill_angle_increment will still be used. The first layer start with the first angle. If a new pattern is used in a modifier, it will choose the layer angle from the pattern as if it has started from the first layer.Empty this settings to disable and recover the old behavior. (°) | default: null |
