Topic: [ASA] - Geloy CR7500

I wanted to try ASA filament because of Thomas Sanladerer's filaween video. I only found two different types of ASA pellets on ebay, ASA TW-23V  and ASA GELOY CR7500. I went with ASA GELOY CR7500 since the TW-23V had a really low melt flow rate.

Extruder:
Nozzle Diameter: 1.6mm
A vertical Filastruder v2.0 #2690 with a filawinder

Drying:
I always dry my pellets before use. I used a toaster oven at 70°C for about 6 hours. The image shows the pellets on the tray after drying.

Comparison to available filament:
I've never bought ASA filament before, so I cant really compare this to anything. It seems to do small details and overhangs better than ABS, but it's layer adhesion is pretty weak. I might try printing with the temp up more.

Takeaway and comments:
The extrusion was really slow and there weren't really any benefits to this over ABS. The diameter was really consistent though and there weren't much fumes. I probably won't be getting any more of this unless I can get the print quality better.
