Looking for guidance printing with ASA. I have done a number of prints with it now, but I seem to have serious issues with getting consistent flow. Often the layers don’t meet in some places which appears to be being caused by inconsistent flow viscosity. I have had the extrusion up to 280 degrees to try and get it more consistent without success. The inconsistent flow ends up causing the print to be particularly weak with thin walls and makes the print look pitted. Printing with a direct setup right using E3D v6 mounted directly to an E3D Titan. Smoothieboard controller.
It prints nice on my machine (eustathios with e3d v6, bondtech extruder and AC heatbed) with these settings:
- hotend 245°C
- Heatbed 100°C first layer, then lower to 95°C
- ASA needs to cool very very slowly. My part fans are off for the first layer then run at 10%. Try the lowest you can and raise a bit if needed.
I have no parts fans running at all. I have found it unnecessary with the ASA.
What is your print speed?
60-80mm/s but I printed some parts at 150-200% speed so it’s not an issue I think.
You should try to add a little part cooling.
I’ve based my setting on that when tuning my first prints : https://3dprintingindustry.com/news/testing-asa-3d-printing-filament-weather-resistant-alternative-abs-62785/
Thank you. I’ll check into that.
You shouldn’t need to exceed 260 in my opinion. 260 is fine if you can make sure the ASA is dry. I’d start from an ABS profile but slow it down a bit. At least my ASA is rubberier than most ABS.
Is this a genuine E3D v6?
Yes this is a late response and yes, it is a genuine E3D v6. I run an online store https://store.timeshell.ca and am a genuine E3D reseller btw.
