Although primarily a desktop application mslicer exposes some of the more basic slicing feature through the slicer command line program. This could be used for bulk slicing of models or for automating slicing of a parametric model like in @colin/phone-case-cq.

Installation

For now, builds of the CLI can be found on the Github Releases page for all major platforms.

Usage

Multiple meshes can be added by using the --mesh argument more than once. If you want to change any properties of the mesh, like position, rotation, or scale, you can use the flag followed by a 3D vector (x,y,z). These flags will modify the mesh defined most recently.

$ slicer --mesh teapot.stl --position 0,0,-0.05 --scale 2,2,2 --mesh frog.stl --position 100,0,0 output.goo

Slice parameters can also be changed from the defaults.

slicer --mesh teapot.stl \
  --exposure-time 8 \
  --lift-distance 6 \
  --lift-speed 25 \
  --retract-speed 100 \
  --first-lift-distance 6 \
  --first-lift-speed 25 \
  --first-retract-speed 100 \
  out.ctb

Usage: slicer [OPTIONS] <--mesh <MESH>|--position <POSITION>|--rotation <ROTATION>|--scale <SCALE>> <OUTPUT>

Arguments:
  <OUTPUT>  File to save sliced result to. The extension must be .goo, .ctb, or .nanodlp

Options:
      --platform-resolution <PLATFORM_RESOLUTION>
          Resolution of the printer mask display in pixels [default: "11520, 5120"]
      --platform-size <PLATFORM_SIZE>
          Size of the printer display / platform in mm [default: "218.88, 122.904, 260.0"]
      --layer-height <LAYER_HEIGHT>
          Layer height in mm [default: 0.05]
      --first-layers <FIRST_LAYERS>
          Number of 'first layers'. These are layers that obey the --first- exposure config flags [default: 3]
      --transition-layers <TRANSITION_LAYERS>
          Number of transition layers. These are layers that interpolate from the first layer config to the default config [default: 10]
      --exposure-time <EXPOSURE_TIME>
          Layer exposure time in seconds [default: 3]
      --lift-distance <LIFT_DISTANCE>
          Distance to lift the platform after exposing each regular layer, in mm [default: 5]
      --lift-speed <LIFT_SPEED>
          The speed to lift the platform after exposing each regular layer, in mm/min [default: 65]
      --retract-speed <RETRACT_SPEED>
          The speed to retract (move down) the platform after exposing each regular layer, in mm/min [default: 150]
      --first-exposure-time <FIRST_EXPOSURE_TIME>
          First layer exposure time in seconds [default: 30]
      --first-lift-distance <FIRST_LIFT_DISTANCE>
          Distance to lift the platform after exposing each first layer, in mm [default: 5]
      --first-lift-speed <FIRST_LIFT_SPEED>
          The speed to lift the platform after exposing each first layer, in mm/min [default: 65]
      --first-retract-speed <FIRST_RETRACT_SPEED>
          The speed to retract (move down) the platform after exposing each first layer, in mm/min [default: 150]
      --preview <PREVIEW>
          Path to a preview image, will be scaled as needed
      --mesh <MESH>
          Path to a .stl or .obj file
      --position <POSITION>
          Location of the bottom center of model bounding box. The origin is the center of the build plate
      --rotation <ROTATION>
          Rotation of the model in degrees, roll, pitch, yaw
      --scale <SCALE>
          Scale of the model along the X, Y, and Z axes
  -h, --help
          Print help
