Welcome to the State College RepRap User's Group Wiki!

  • Our meetings are on the 1st and 3rd Wednesdays of the month at 7pm at The Make Space, downtown in the alley behind Green Bowl and the Frasier Street garage.
  • Thank you for visiting our page. We are a group of RepRap users based out of Penn State & the State College area. We participate in designing new parts and improvements for RepRap and have created a new merging of the Mendel and Prusa RepRap designs which we call the Open Hybrid Mendel, or OHM for short. We also are developing the RepRap Mullis as a low-cost laboratory robot capable of preforming DNA amplification via a polymerase chain reaction.
  • Our project is combined with class offerings at Penn State, so if you are interested and attend PSU be sure to contact us for information!

What's New?

For what used to be new, check PSU RUG History.

  • 9.17.12: Archived news 3+ months older. More news should be posted soon!


All information about our electronics that we use, including firmware can be found here.


Anything and everything that deals with software will be here eventually. (WIP)

REPSNAPPER: Here is a basic video tutorial to help you get started!
