MOST Delta Performance Mod

▼This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printingPlease leave comments using the talk page. The course runs in the Fall semester. It is not open edit.

To print materials other than PLA, a controlled environment is needed to prevent rapid cooling which leads to plastic warping. After searching for enclosure modifications, I decided to create my own, low-cost modification to fix a relatively simple problem. My design has been created as an affordable, "good enough" solution.

• Using this enclosure, ABS and nylon are now within reach of any MOST Delta builder with a simple modification that can be completed in the average dorm room.

• 
  External Heat Shield
• 
  Testing Insulation Capability
• 
  Cooling Rate (Degrees F vs Minutes)
• 
  New Hotend (E3D v6)

1. (3) 12x18in thick cardboard
2. Aluminum Foil to Cover

• Total assembly time is roughly one hour..
• If you have any large gaps, they will need to be filled or covered with foil. This is to prevent excess heat loss.

After testing various combinations of plywood and available sheetrock, and their insulating values, I settled on aluminum foil wrapped cardboard as the most accessible and affordable. However, this does not diminish the quality of insulating ability provided.

1. Cut the cardboard to ensure a tight fit, and wrap in aluminum foil.
2. Apply magnets to cardboard panels and delta wood.

• 
  Step 1: Lay Out Cardboard, with magnet
• 
  Step 2: Secure Magnet
• 
  Step 3: Wrap in foil
• 
  Step 4: Assemble

The enclosure was tested by heating the interior air with a blow-dryer up to ~130F. The temperature was then measured at 60 second intervals to test the insulating value of the enclosure, and the results can be seen in the gallery above.
