As the cold weather season arrives in Atlanta, with it comes issues with our 3D printers. Specifically problems with temperatures and print stability. Freeside is essentially a big warehouse, and our 3D printing station is setup in the large open area in the front of the space. What this means is that when it is cold in the space, this will affect the printing quality because the ambient temperature is far lower than what is optimal for thermoplastics. The cold ambient air will cause parts to rapidly cool during the middle of a print. And with materials like ABS which can shrink dramatically during cooling, this causes prints to warp, deform, and delaminate during and after printing is finished. The print on the left is showing signs of delamination from plastic cooling mid print. To remedy this, we built an acrylic enclosure for our LulzBot AO-100, which is our dedicated ABS printer. We tested the proof of concept of whether an enclosure would help mitigate printing problem
