Is there any 3D-printing software that supports Raspberry Pi?
The answer is &quot;yes&quot;, but it depends on what hardware you have, what operating system you are using, and what software you want (or need) to use.
I have a Raspberry Pi 4 with 4GB of memory, and I am running a 32-bit version of Raspberry Pi OS. I have been able to install the following software from the Raspberry Pi OS repositories, but not everything is working &quot;out of the box&quot;:

Blender 2.79 (starts, but not tested)
Cura 3.3.1 (crashes on startup)
FreeCAD 0.18 (crashes when opening a new document)
PrintRun (PronterFace) 1.6.0 (working)
PrusaSlicer (Slic3r PE) 1.39.2 (working)
Repetier-Host 0.85 (crashes on startup)
Slic3r 1.3.0 (working)

I have been able to download the 3DBenchy from Thingiverse, slice it using Slic3r, and PrintRun (PronterFace) is currently printing it on my Tronxy X1.
I will update this answer if I can get the other stuff working, since I would quite like to use a Raspberry Pi for 3D design and printing. If I can get FreeCAD working, I shall be happy, and OpenSCAD would be a welcome bonus, but I don't think that it has been ported.
