This is the page for the State College Rep Rap User Group's (SCRUG)Black 3D printer. The printer was developed and assembled by students in Penn State's Engineering Design 497J course and members of the 3D printing club. Our goal is to continuously tweak the printer until it is ready for distribution and sale to other departments in the University and local schools and businesses. This particular printer was transferred to Penn State's Material Science (MatSE) Department

This printer is mainly comprised of black frame pieces with a few green pieces mixed in. On the board Black is labeled as Black and Green.


Date Modification / Problem
02/05/2014 X-axis a little bit off.
12/05/2013 Waiting on working RAMPS. Should be functioning soon.
12/02/2013 Printer is assigned to be the Demo Printer. Should not be removed from the cart.
Unknown Quick-leveling Bed Thumbwheels
Unknown Maximized Print Bed
Unknown Spool Holder


Spring 2014 was quite the rebuild

Things that have been done:

1. Convert to RAMPS electronics

2. Align x-axis

3. Wire/make hot end

4. Assemble entire extruder assembly

5. Flash Arduino Board

Things to be done:

1. Figure out/fix thermistor issue (constant reading around 7 degrees C, even when no thermistor connected)

2. Wire additional end stops

3. Test and Tune

Build Progress

This section includes the progress the build team has made on the black printer. Final Update


Things that still need to be done:

1. Finish assembling the extruder

2. Finish assembling the x-axis and z-axis

2. Solder the thermocouple junction onto the electronics board

3. Connect all wires to the electronics board

4. Organize the wires so they will not be in the way while printing

5. Test. This printer has not been connected to a computer yet
