TOOLPATHS

Toolpaths is a Grasshopper plugin for generating and simulating G-code. Its goal is to enable new ways of 3D printing and CNC milling while giving novices and experts alike full control of the machine's movement.

Core Features

• Object-Oriented Toolpaths

  The core data type is the Toolpath, which encapsulates a curve with its associated metadata (speed, extrusion, etc.) into a single object.
  Granularity: Assign parameters per-path or per-segment.
  Compatibility: A Toolpath object remains a standard Grasshopper geometry type, allowing you to use native components for transformations without losing metadata.

• Toolpath Inheritance

  Settings follow a simple priority: FDM Defaults (lowest) → inherited Toolpath settings → local Toolpath overrides (highest). Connect one Toolpath to another to inherit its settings, then override only the values that need to change.

• Simulation

  The FDM engine simulates material deposition rather than just visualizing a mesh pipe. By calculating volume buildup the solver enables features like automatic flow adjustment.

Install

1. Request a trial key on the TOOLPATHS trial page. Your key is sent automatically by email.

Quickstart

---

A Toolpath combines geometry with the properties used to print it. The FDM Processor collects the Toolpaths, applies defaults and machine settings, and creates one program. The FDM Simulator displays that program as a mesh, and FDM G-Code Output writes the program as G-code.

FDM Toolpath

The FDM Toolpath combines a curve with printing properties such as extrusion volume. Right-click the component to reveal its optional property inputs.

Connect a curve to the Curve input; a polyline is recommended. Other curve types are automatically converted to polylines with 0.3 mm sampling. You can also connect another Toolpath to inherit its settings.

Toolpath Inheritance

Download the inheritance example

Toolpath components can be chained. A Toolpath inherits settings from the Toolpath connected to its input, then applies its own local overrides.

In the example, each Toolpath keeps its own speed, while the Z-Hop value is set to 3.2 for both.

If a property is not set locally or inherited from the connected Toolpath, the value from FDM Defaults is used.

Toolpath Geometry

Toolpaths are geometry, so you can transform them with standard Grasshopper components such as Move, Array, and Transform. Toolpath properties stay attached through these transformations.

Extrusion Modes

TOOLPATHS has five extrusion modes. They define how much material is deposited for each millimeter of travel, or specify that no material is deposited.

1. Volume Mode: Sets the volume of material deposited per millimeter of travel. For example, 3 mm³/mm deposits 3 mm³ of material for every millimeter traveled. The simulator uses the volume and the height of the material below the nozzle to calculate the preview geometry.
2. Static Mode: Sets a fixed extrusion width and height. The simulation does not adapt the extrusion shape to the height of the material below the nozzle. This can be faster for large models.
3. Auto Width Mode: Sets a target extrusion width. TOOLPATHS calculates the required volume from the available height below the nozzle. This is useful when layer height varies, such as in non-planar printing.
4. Auto Ratio Mode: Sets a target ratio between extrusion width and height. TOOLPATHS adjusts the extrusion volume to maintain that ratio.
5. No Extrusion Mode: Moves the printer along the path without depositing material.

Flow multiplies the extrusion amount calculated by the selected mode. For example, Auto Width Mode first calculates the volume needed to reach the target width, then applies the Flow multiplier. Flow can also be varied along the path with the Flow Modulator.

Download the Toolpath Object Options example

Extrusion Calculation

TOOLPATHS simulates all extrusions in a global heightfield. The heightfield, extrusion calculation and preview mesh are tightly related.

Settings for the heightfield are exposed in FDM Defaults:

• Heightfield Resolution: HFRes defines the resolution of the heightfield. Details smaller than this cannot be captured.
• Meshing Resolution: during simulation the toolpath is resampled based on this distance and at every point the heightfield is sampled. In Auto Width Mode the extrusion amount is calculated at every sample point.
• Smoothing Window: The preview mesh is slightly smoothed by default, as extrusion cannot change instantly. Affects preview only.

Auto Extrusion and Degenerate Extrusion Detection

Auto Width Mode is convenient, but it can produce unintended results.

Example: the extrusion width is set to Auto Width 2 mm and the toolpath bridges over a gap. The algorithm evaluates the available height, which might be large (for example 10 cm if the bridge occurs higher in the print). Based on this, it attempts to deposit enough material so the extrusion approaches the target 2 mm width. This can lead to excessive material being extruded. Degenerate Extrusion Detection and layer-height limits are used to handle these cases by capping the amount of material that can be extruded.

Degenerate Behavior

A degenerate extrusion is an extrusion that has zero height or zero width. This can happen when a toolpath is too close to existing printed geometry. Degenerate modes handle zero-thickness points by either calculating replacement values from neighboring samples to maintain continuity (0) or flagging them as suppressed to omit them from the simulation (1).

Degenerate Aspect Ratio

Extrusions with a width / height aspect ratio larger than this are considered degenerate.

Minimum Layer Height

Extrusions with a layer height smaller than this are considered degenerate.

Maximum Layer Height

Extrusions with a layer height larger than this are capped at this height.

Modulators

---

Modulators

Modulators change a Toolpath after it has been created. They vary parameters along a path or reshape its geometry. A modulator takes a Toolpath as input and outputs a new Toolpath with the modulation applied. Most modulators work per segment or per vertex. For example, the Flow Modulator writes a flow multiplier for every segment, while displacement modulators move the Toolpath vertices.

Typical uses include:

• varying extrusion flow along a path
• changing print speed per segment
• changing extruder temperature along a path
• displacing a path with vectors, normals, or an interpolated vector field

Numeric modulators such as Flow, Speed, and Extruder Temperature use the Vertex Mapping input (VMap) to map a list of values onto a Toolpath. A single value applies throughout the Toolpath. For multiple values, choose one of these mapping options:

Value	Vertex Mapping option	Behavior
0	Constant	Use the first value everywhere.
1	OneToOne	Require one value for every vertex.
2	Wrap	Repeat the value list along the path. This is the default.
3	RepeatLast	Use the final value after the list runs out.
4	Normalized-Stepped	Distribute values along the normalized length of the path in steps.
5	Normalized-Interpolated	Interpolate between values along the normalized length of the path.

Masks

Masks control the strength of a modulator along a Toolpath. They are lists of numeric values, usually mapped per segment or per vertex.

Common values:

• 0 = no effect
• 1 = full effect
• 0..1 = blended effect

Some modulators clamp masks to 0..1. Others use the mask as a direct multiplier, so values above 1 can amplify the effect and negative values can invert it. For predictable results, use 0..1 unless overdriving is intentional.

Masks do not modify Toolpaths by themselves. They are connected to modulators to restrict, fade, or scale effects, for example by region or along a gradient.

Generators

---

Toolpaths is built to give designers fine-grained control at the level of individual extrusions. It does not focus on automatic slicing or fully automated toolpath generation. Instead, users define and design the curves themselves.

To support this workflow, Toolpaths includes a small set of curve-generation components called Generators. Generators output polylines, not Toolpath objects.

2D Generators

Infill Generator

The Infill Generator fills a planar polygon with patterns such as Gyroid or Monotonic infill. By default, the input region is offset inward by half the infill spacing to avoid overlap between walls and infill. Adjust the offset through the Infill Offset input.

Walls Generator

The Walls Generator creates multiple inward offsets of the input polygon. The first offset is positioned at 0.5 × line width from the polygon boundary, ensuring the extrusion fills up to the edge without overlap.

Walls Generator can also be used for outward offsets or with explicit values. Right-click the component for options.

Walls + Infill

The Walls and Infill Generators can be combined to fill a polygon. Connect the Infill Curves output from the Walls Generator to the Infill Generator.

3D Generators

Planar Slice Generator

The Planar Slice Generator slices the input geometry into horizontal layers. Intersections are calculated at each layer’s midpoint, but the output polylines are placed at the layer ceiling. This matches the actual extrusion behavior: the nozzle deposits material downward, so the middle of the printed layer aligns with the intersection plane.

Brep-Plane intersection curves are resampled and output as polylines. Convert the input to mesh for faster slicing.

Vase Mode Generator

The Vase Mode Generator creates a helical path on the surface of the input geometry. The output curve is also resampled either by length (sampling mode = 1, default) or angle (sampling mode = 0). Length-based sampling produces consistent distances between sampling points. Angle-based sampling results in vertically aligned control points.

Angle-based sampling can be staggered so that the pattern alternates and repeats every N layers. Stagger can be combined with the Normal Displacement Modifier to create seamless surface patterns.

Base and top thickness can be used to slice the start and end of the shape into planar layers, commonly to create a solid bottom layer.

The center axis is usually inferred from the bounding box center and points straight in the Z direction. For slanted input geometry, it may help to define a tilted axis explicitly.

Advanced Slicing

---

Non-planar Slicing

Non-planar slicing uses a two-step transform. First, the input mesh is transformed into a planar version with flat top and bottom boundaries. This allows standard slicing methods, such as Vase Mode or Planar Slicer, to generate regular toolpaths. After slicing, the inverse transform is applied to the toolpaths, bending them back into the original shape of the input mesh.

Planar Transform

The first step is to transform the geometry so that the layer lines become horizontal in the transformed state. This is commonly used to align layer lines with a non-planar upper edge.

The Planar Transform component takes a mesh and a set of base and target surfaces, then deforms the mesh accordingly. Base and target surfaces can be supplied explicitly. If they are left empty, the component infers them from the input mesh:

• Base Surface 1: a fitted surface through the upper naked edge of the mesh
• Base Surface 2: a horizontal planar surface at the bounding box minimum
• Target Surface 1: a horizontal planar surface at the bounding box maximum
• Target Surface 2: a horizontal planar surface at the bounding box minimum

With these defaults, the transform enlarges the input geometry in the transformed state. After slicing, the inverse transform compresses the generated toolpaths back onto the original shape. As a result, the layer height used in the transformed state becomes the maximum layer height after the inverse transform.

Slicing and Inverse Transform

The transformed mesh can then be sliced with planar methods. The resulting toolpaths are transformed back using the inverse of the initial transform, so they conform to the original input geometry.

Download the Non-planar Slicing example

Layer Height Field

Vase Mode Generator and Planar Slice Generator can produce varying layer heights based on a Layer Height Field. Use the Layer Height Generator to create fields by interpolating explicit values or using the slope of input geometry. The number of output layers is automatically determined to achieve the target density.

A profile curve, together with minimum and maximum layer height values, can be used to vary layer height based on slope. By default, the mapping is absolute: horizontal areas map to MinH, and vertical areas map to MaxH.

Enable Normalize Input by right-clicking the Layer Height Generator to remap the actual slope or curvature range of the input geometry to the full [MinH..MaxH] range. This makes the layer height variation relative to the geometry itself, rather than to an absolute horizontal-to-vertical range.
