Immediately after posting our Creme Brulee torch videoÂ we knew we made a mistake. We wanted to show you that Ultem was a significant material because it was certified for use in commercial aircraft. We wanted toÂ illustrate that by burning an Ultem part with a Creme Brulee torch. Several commenters and bloggers however saw the video and went, “whats the big deal here?” We realized that we probably spend a bit more time burning thermoplastics than other people. To adress the issue we went back and made another video for you. In this video you can see a direct comparison between a standard 3D printed ABS part and the Ultem part. You can see that although the Ultem part does indeed deform it does not give off significant fumes and it acts as a fireÂ retardant. I hope that this video is clearer!
