Workhorse MakerBot 3D Printer At iheartengineering
iheartengineering found that the key to producing large parts without warping was to maintain a stable ambient thermal environment.
This was especially true because their offices are located in a converted brick warehouse building with concrete floors, lots of drafts, and inconsistent heating during the winter.
To deal with the unstable office temperatures, and to make sure that any objectionable vapors given off by the MakerBot were exhausted outside the building, they constructed a simple housing and venting system.
As a part of the venting design they needed a part to mate between the housing and off the shelf ducting. So they did what any self-respecting engineering firm would do - they quickly designed the part they needed, using open source CAD software of course, and printed it out on the MakerBot.
The special housing allows them to run the 3D printer continuously for hours, and sometimes for days, on end. The stable temperatures result in consistent prints as well as allowing them to produce parts as large as the MakerBot workspace will allow.
