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)
Bill of Materials[edit | edit source]
- (3) 12x18in thick cardboard
- Aluminum Foil to Cover
Technical Specifications and Assembly Instructions[edit | edit source]
- 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.
Notes[edit | edit source]
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.
Assembly Instructions[edit | edit source]
- Cut the cardboard to ensure a tight fit, and wrap in aluminum foil.
- 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
Results[edit | edit source]
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.
