  34. 34. FILAMENT TIPS •We have some donated plastic here to play with. YMMV • The “cheap plastic” is often expensive if time is a cost • Buy your own plastic to learn what you are printing with • Buying from a renowned vendor will save you time and grief (use Ultimaker, Faberdashery, DiamondAge, Ultimachine, GRFF or Protoparadigm) • Colorfabb’s PLA/PHA mixture can be difficult to work with unless you only print with that one plastic. It’s more sticky... Thursday, September 25, 14

Only Bitraf members may use the printers (as well as other machines). 4. For good prints - buy your own quality plastic. Keep it in a bin in the Lab. 5. No unattended printing. When the last person leaves - all 3D printers are turned off along with all other equipment. Thursday, September 25, 14
  64. 64. HOW TO SOLVE COMMON PROBLEMS Thursday, September 25, 14
  65. 65. SWITCHING PLASTICS • Feed plastic manually until new color shows • Keep extruding for a while or do a test print • Old colors will keep contaminating your print until you got it all out • Slightly hotter temp may help cleaning out the old Thursday, September 25, 14

  67. 67. PTFE insert (White plastic) Peek tube Aluminium heater block Copper nozzle HOTEND Thursday, September 25, 14
  68. 68. CLOGGED HOTEND (A) 1. Warm extruder to 200C 2. Hold aluminium block still with a wrench 3. Use another wrench to unscrew the copper tip. Can’t be done when cold! 4. Heat copper using a burner 5. Insert a piece of ABS/PLA firmly into the warm tip. Wait a few seconds and pull back. This removes plastic & impurities 6. Use the wire of a resistor to push any impurities into the nozzle tip & then do #4 + 5 until clean 7. Re-assemble while warm or it won’t fit Thursday, September 25, 14
  69. 69. CLOGGED HOTEND (B) If you leave the extruder hot for a long time you’ll create one of the most time-consuming problems for yourself. A plug forms here since the heat creeps up the brown PEEK piece. When you try to push warm plastic into a tube, it expands and creates a plug... Thursday, September 25, 14
  70. 70. CLOGGED HOTEND (B) To solve this, you need to: 1. Heat the extruder & retract the filament 2. unscrew the long screws 3. Lift out the hotend assembly so you can remove the plug 4. Screw the thing back together while you make sure the bowden tube is flush with the white plastic piece that goes into the brown peek. Any gap there will allow plugs to form again.
