I'm all for PC!

I'm working on my own hot end design and today I got around to testing some polycarbonate. I had tried printing this previously at 260C and although it would extrude the layers just didn't bond very well. With the all metal hot end, I tried again at 290C. I was very happy to see this time the layers stuck together, in fact it is quite strong given it is only one layer. Although I think, surprisingly, the best attribute to PC is the amazing silver like shine it has, unfortunately somewhat lost in this photo. It is also very transparent, even more so than clear ABS or PLA.
