I'd like to speed up my print speed but I wonder if print speed is more dependent on the printer or the print filament.

As far as print filament goes, I don't see much point to printing in PLA unless it's just for demonstration or toys since it doesn't stand up to heat. I print almost exclusively in ASA which is like a UV resistant ABS. I'd like to try poly carbonate but I've been too lazy to change to a high temp print head.

Info on ASA: 3DXMAX® ASA (Acrylonitirle Styrene Acrylate) is a UV-resistant, famously weatherable polymer. Our ASA has a low-gloss matte finish which makes it the perfect filament for technical-looking prints, especially when you don’t want the high-gloss surface finish often associated with 3D printing materials like ABS, PETG, or PLA.
