Prusa i3 printer

The Prusa i3 is a 3D printer at Quelab. It was built when the Prusa Mendel caught fire; Ben K and Morgan G worked through a long night to get the carcass of the old printer disassembled and a new shell made.

It's pretty fly.

Parts & attribution

Most hardware was salvaged from the Prusa Mendel printer. Only a few parts have been purchased or scavenged from outside sources.

Parts used (to some degree of knowledge):

Parts were laser cut on OUR LASER CUTTER from SCRAP! And it looks pretty good all things considered.

Preflight checklist

Extruder fan The e3d v6 hotend requires active cooling. Before printing, make sure that this fan is spinning properly. placing your hand near the fan, you should feel a slight breeze as air is pulled into the fan and over the cold block.

If this fan does NOT turn on when the power supply is on, STOP USING IT and report it to the 3d-printing mailing list.


The glass takes FOREVAAAH to heat up. Give it 10 minutes to come to temp after the thermistor reads the preheated values. This will help with bed adhesion.
