David Weis graciously decided to lend us his Original Prusa i3 MK2 printer.
The printer can be used for printing with PLA or PETG filament, with a 1.75mm diameter.
Other filaments have to be discussed on the mailing list. If you wish to print with ABS then additional ventilation will be required to deal with styrene fumes.
TPU or TPE flexible filaments (such as NinjaFlex) may be used but require use of talcum powder or painters tape on the PEI print surface.
PEI SHEET WILL GET DAMAGED IN CASE YOU PRINT TPU DIRECTLY ON IT!!!
Use of your own filament is only allowed with a previous discussion with other members to prevent usage of low quality or non-suitable filament.
As the owner of the printer David reserves the right to take the printer out of the lab for few days or print really long prints.
It's unlikely this will ever happen without a prior warning on the mailing list. Unless it's a case of dire printing emergency!!!
You can use two different slicers with the Prusa.
If you wish to use a different slicer you can ask on the mailing list. But unless you have a very good reason to use a different one it's advised to stick with the listed options.
The Prusa MK2 will automatically calibrate before every print.
Do not use the calibration option on your own without a previous discussion on the mailing list.
Printer is using an unmodified version of the the original Prusa MK2 firmware. We have no intention of changing this.
Unless you are experienced with 3D printing it is highly recommended that you ask on the mailing list for help with your first few prints.

David is politely asking that you train yourself on the Ultimaker 2 before touching his printer.
