Introduction[edit]

Heated Bed Setup  

This page describes my custom modifications to the MOST-Delta printer constructed at Michigan Technological University as part of the graduate level final project for MY4777/MY5777/EE4777/EE5777 Open-source 3-D printing . During initial construction of the printer I was immediately planning modifications to help with better print quality and to allow for various printed materials. Instead of a single modification I made multiple modifications to build my personalized printer to my specifications. The final goal of the semester long project was to print with ABS on a heated bed.

In order to complete this task multiple modifications needed to occur. The first and most difficult modification was in the power supply. When using a heated bed there is an extra 10 Amp draw that needs to be accounted for when powering the printer. The cheapest route to increase the power to a minimum of 15 Amps was to modify a 203W 16.5 Amp XBOX 360 Power Supply. This unit was free since I had a broken XBOX in the closet suffering from the "Red Ring of Death." Once the power supply requirements were met the RepRap MK2b heated bed was wired and installed. To attain a flat and level print surface a borosilicate glass panel was obtained. This material can stand up to multiple heating and cooling cycles without shattering. A GeeeTech 100k termistor was implemented to control the bed temp. After all of the modifications were completed the firmware was adjusted to allow for the use of a heated bed, and new tie rod lengths from the carbon shafts.

Listed below are the modifications that were completed this semester to allow for the use of ABS material:

  • 203W Modified XBOX Power Supply
  • RepRap PCB MK2b heated bed
  • Borosilicate Glass Print Surface
  • Carbon Tie Rods
  • Aluminum Pulleys
  • ZeniKentics Spool mount
