OVERTURE ASA Filament 1.75mm with Build Surface 200mm × 200mm, Premium Anti-UV 3D Printer Consumables, 1kg Spool (2.2lbs), Dimensional Accuracy +/- 0.05 mm, Fit Most FDM Printer (White)

It took me about a week and 20 failed prints to get my first part to print without shrinkage and other issues, but this is expected of ASA. Users should know that the fumes are toxic; even in a pretty well ventilated place I ended up with a migraine.This particular product seems to be good quality and performs well on my Ender 5 Pro after finally finding the right settings. The settings recommended with this product didn’t work well. Perhaps this varies from one system to the next. I kept my bed temp as high as it would go and used a textured mat. Printing very slow was essential. If using ASA for the first time, I’d suggest experimenting with test prints that don’t take too long. I had to make a lot of design features to accommodate the behavior of the plastic (such as extra holes and gaps.). When it finally worked out the product seems very strong and durable.

This was my first ASA filament. This was easy to use and the print came out perfectly. I did have to slow down the speed some but the instructions on the side of the spool indicates the speed so it was easy to use.

Very satisfied with my first spool of ASA filament for use with my FLSUN QQ-S Pro! Processed using my PETG settings as a starting point, and did not have to change much for the nozzle and bed temperatures. It almost prints, buttery smooth, and when a brim is used to facilitate bed adhesion, the brim peels off as easy as with PLA. Bed adhesion is part dependent, and has printed satisfactorily with and without PVA adhesive (glue stick). The filament is well behaved on the roll, and makes for easy prep. It definitely has a distinctive (sickly sweet) odor during printing, but fortunately, my printer has an enclosure with an air scrubber, which I highly recommend for all 3D printing, regardless of polymer.I would have already bought a roll in black, but OVERTURE only seems to carry white.

This was my first go at ASA. I got the white. Let me start by saying I LOVE Overture PETG white. Been using it for a few years. This spool made me want to never try ASA again. Used an entire spool and still couldn't get it to print right. Printing on a voron 0.1, I tried tuning everything, flow rate, pressure advanced, towers, you name it. No moisture, but always had inconsistent layers, blobs, and artifacts. Tested in Temps between 240 - 260, made no difference on my printer. Settled at 245. Tried different retractions, speeds ranging from 30 to 120. Settled at 120 infill, 40 outer, 80 inner, 40 top/bottom, and 25 initial layer. Fan speeds from 0 to 100% and ultimately left it at 100 as it was the best looking. I tried with it fully enclosed and without the top on. I ended up leaving it without the top. This made me think I had toolhead wobble, so I completely upgraded to a larger mgn9 rail and it still didn't change. Several people said white is always horrible and try a different color. I got orange from another brand and it print great. No inconsistent layers, artifacts or blobs. I may try white again but from a different brand. Maybe I just got a bad spool...

This is very good filament! ASA prints very well and seem forgiving. If I have any complaint it is that the material is VERY prone to static generation; any tiny bit that you sand off becomes charged, almost like working with PVC pipe. I was testing with White, which is the best printing white filament I have ever used, so could really see how much the little white specs would cling to every surface. It isn't enough to keep me from using it, but should be kept in mind.It has very good adhesion, almost too much as support material was harder to remove than it is with ABS, and I had to increase distances and lower density to compensate.
