We are ending support for PrusaSlicer.

Move to: Pantheon Slicer


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 PrusaSlicer (2.6.0-beta)

PrusaSlicer 2.6.0-alpha6 download links below.

You can find more builds on the release page here:


Extract the folder and place it somewhere sensible. A good location would be your C:\Program Files directory


Move the dmg file into your Applications folder

Launching the application for the first time

To open PrusaSlicer, navigate to the folder where you moved it, and open prusa-slicer.exe

You may get a pop-up welcoming you to the PrusaSlicer Configuration Wizard. The Configuration Wizard is used to set up the slicer program with some common 3d printers; however you can click cancel as you will be importing the configuration bundle for the Pantheon HS3.

Make a shortcut to the application or pin it to your menu if you like.

Configure PrusaSlicer for Pantheon HS3

Download the Pantheon HS3 config bundle below:

Config Bundle

Printer Model

Config Bundle

Pantheon HS3 (gen 2)


Open PrusaSlicer and navigate to File -> Import -> Import Config Bundle... Select the Pantheon_PrusaSlicer_config_bundle_Rev3.0 you just downloaded

note: there is also an option here called Import Config..., this is NOT the right option

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

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.


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

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

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,


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
