Before using our printers, please attend the monthly introductory 3d printing workshop. You can register at https://tickets.mumalab.org/courses/.

3D printers

There's a number of 3D printers at the space:


  • Do not modify the printers in any way. Do not change the nozzles by yourself. Never flash any firmware.
  • If there is a problem or you need to do a nozzle change: Ask in the #3d_printinting channel on slack beforehand or ask someone from List of Contacts
  • Do not print unsupervised. Check on your print at least every half hour or so. We really want to avoid damage to the printers and the potential fire hazard.
  • Do not scrape with anything sharp on the build plates
  • Do not use anything other than isopropyl alcohol on the build plates
  • Do not print abrasive materials
  • Power off printers after use


The 3D printers are free to use, but please bring your own filament. We recommend you use original Prusament filament. The printers are provided with space funds and our own free time, so please clean up after yourself and notify someone (e.g. in Slack or at List of Contacts) if something goes wrong.


To get good results we recommend using PrusaSlicer (also see PrusaSlicer on our wiki).

Useful Resources

Metasearchengines for 3D files

  • Thangs: Can search for names and related geometry.
  • Yeggi: CAn search for tags over a vast amount of 3D File Hosts.
  • STLFinder: This is a meta search engine. It mostly returns results from Thingiverse, but they are quite often better than those of Thingiverse's own search.

Youtube Chanels

  • The YouTube channel CNCKitchen has very scientific and useful overviews on how slicing parameters affect the print, and much more.

Software to Fix STL Files

  • Meshmixer: a bit old but it does the job
  • Fusion 360: Yes it got a new feature for fixing meshes
  • Meshlab: A bit complicated but it has a verry large feature set for fixing 3D Models
  • Aspose: An automatic free online service for fixing 3D Files

Design Software

  • Fusion 360: The most know and common CAD Software quite easy to learn
  • OpenSCAD: If you like programming and are masochistic you can use this and no chatGPT doesnt give you good results
  • Tinkercad: The easy 3D Online CAD so easy a Prescooler can use it
  • OnShape: Only the free tier is limited
  • Blender: There is CAD and 3D Printing plugins but the learning Curve is quite Steep
  • Free CAD: Its a free cad software you get what you pay for
  • plasticity: Easy to use but its like 99$ if you need it for more than 30 Days. It has a different aproach to modeling its like fusion360 mixed with blender
