In my search for more interesting filament, today's experiment is Taulman Alloy 910
Since my Mk3 is equipped with an E3D NozzleX, I had to choose my temperatures a bit higher.
Profile: Chris' MK3 Pretty PETG
Filament: 260°C / 265°C
Most importantly: YOU NEED GLUESTICK ON THE BED
Taulman itself has a short paragraph about PEI print beds where they advice against using PEI beds. Otherwise, the print will easily peel off, but I had good experience with generic gluestick on the PEI sheet where it sticks good enough to cause those small bubbles under the PEI sheet.
Even a print with the worst case for warping (slim, long, sharp edges) it adhered well.
For now, I'm still looking how to get rid of those discolored / burnt marks. I suspect that thats material sticking to the nozzle which then gets deposited on the part sometimes. Well, the burn marks are from a leaking heating block...
