ABS Microclimate

General LulzBot TAZ
1

This is my attempt at meeting the following requirements to improve ABS output:

  1. Very low cost
  2. Very light weight materials and heat rated 110C+
  3. 60C+ air temp
  4. Keep steppers, extruder, rambo and filament within suggested operating temp
  5. Easily removable
  6. Print duration less than 7 hours

As a result, I built an expandable type of pizza box that really just isolates the build area from everything else. I designed it around the constraints of the TAZ itself with minimal intrusion on the platform. If anyone is interested I will post results after some testing. The topper weight a little more than a Nema 17 in hand - less than 16oz. Either with the ceramic space heater or the built in bed it will maintain 70C.

Interesting. What did you make the accordion section out of?

The accordion is made from household radiant barrier. It’s an Aluminum/PET/Aluminum sandwich. The guide strings are polyester.

This seems original and creative - well done! I have an idea like yours but a little different, as it is open not closed. Have a look at this post:

and maybe we can collaborate or toss ideas around until something works?
