Pantheon Slicer(BETA)

On July 12 we have released Pantheon Slicer (BETA)

Reasons we forked our own slicer:

  • Automatic updates for our printers profiles

    • no more deleting and re-importing profiles

    • whenever print profiles are updated you will get an in-app notification

  • New Functionality in development


Slicing a part is how we get our 3D model into a code our printer can run. Slicing is equivalent to CAM or programming in the CNC world. The slicer takes parts and “slices” them into layers that the printer prints. The slicer generates the exact path the nozzle follows. Things like wall thickness, top and bottom thickness, speed, etc are all configured in the slicer.

Please read this entire document before slicing and printing with the Pantheon HS3.



Install PantheonSlicer (2.6.0-beta1)

Download Link



Mac OS

(Apple Silicon)



Download and run the installer above.

Once installation finishes you can launch the application. The config wizard can be skipped with the “Finish” button as there are no options to configure.

Mac OS

Download the .zip above, unpack it and copy the file into your Applications folder.

You can now launch the application. The config wizard can be skipped with the “Finish” button as there are no options to configure.

Importing a Part

PrusaSlicer is compatible with the following file formats: STL, 3MF, OBJ, and AMF

You can either drag and drop files directly into the PrusaSlicer window or use the add button highlighted below.


Orienting a part

You will need to rotate the part onto a face to print it, your part may import in the correct orientation already but this step is often necessary

The Easiest way to do this is to use the place-on-face tool. Click your model, then click the place on face button. Faces will appear on your part, select the one you want contacting the bed and the object will rotate into place


Slicer Settings

The red box highlights the settings dropdown

Updating Slicer Settings:

Pantheon Slicer checks for settings updates automatically at startup. If updates are available a message will be shown on screen in the bottom-right corner of the plating area.

Overview of Print settings, Filament, and printer:

Select the profile according to the material you are printing with.

0.2mm Carbon Fiber PETG Rev3.1

Default setting for PETG parts.

0.3mm DRAFT Carbon Fiber PETG Rev3.1

Reduced print time by 20-40%. Larger layer height and less resolution, but will get it done fast.

0.2mm Carbon Fiber Nylon Rev3.1

Default setting for CF-Nylon parts.

0.2mm Glass Fiber Nylon Rev3.1

Default setting for GF-Nylon parts.


More information about our filaments can be found here:


Carbon Fiber PETG Rev3.1

general purpose material:

  • 45-50 MPa tensile, depending on process settings

  • operating temp up to 70°C

  • great layer bonding - 85% isotropic

  • good UV/chemical resistances

All the printed parts on the HS3 motion system and frame are printed in CF-PETG

Carbon Fiber Nylon Rev3.1

High temp, High Stiffness, High strength

  • 95-120 MPa tensile, depending on the process settings

  • Operating temps up to 140°C

  • super stiff - 8150 MPa modulus

  • resistant to creep at high temps

We use this for components on the print head exposed to high temperatures

Glass Fiber Nylon Rev3.1

High temp, high impact, high lubricity

  • 90-110 MPa tensile, depending on the process settings

  • Operating temp up to 95°C

  • low friction, high lubricity,

We use this for most of our assembly jigging


Pantheon HS3 V3.0

  • that's our only system, so hopefully, that's why you are here

Slicing and Exporting

Once you have imported a model, orientated it, and selected your process settings you can slice and export the file (.gcode)

Click the Slice Now Button, then the Export G-code Button, and save the file

You are now ready to upload and print on the HS3
