Siraya Tech Fibreheart ASA-GF 3D Printer Filament, 10% Glass Fiber Reinforced, Superior Weather & UV Resistance, High Strength & Thermal Stability for Outdoor & High-Impact Applications (1kg, Black)

I love the ABS-GF. I use it in parts subjected to high vibration with the occasional impact, and it holds up great. It also prints beautifully as long as it's nice and dry. Likes to warp a little off the build plate, but no worse than normal ABS/ASA.

Grabbed a roll on a lark since the price was right, $30 for a spool of ASA is right in line with what im used to paying for Polymaker and the advantages of a filled filament were too tempting to pass up the experiment. Gotta say, this stuff is absolutely fantastic, the glass-fill helps a lot with the normal warp issues you get with ABS/ASA filaments. Parts come out like they should, strength is just as good as or even slightly better than regular ASA, and the matte finish is pretty attractive too. Only downside, if you can even call it that, is you definitely need a hardened nozzle, the glass fibers will eat right through standard brass nozzles. I printer mine through a cheap-o tungsten carbide .6mm nozzle, I've had 0 issues with clogging or print defects. Some minor blobs, and I do have to print this slightly slower than standard ABS, but the increase in strength and printability more than makes up for the blobs. Haven't had any moisture problems eitherOverall, cheaper than ASA-CF, if you can even find it, more printable than CF-Nylon, and stronger than plain ASA, all for the same cost of plain ASA makes this a win in my book

Printing a sample on my k2pro, this stuff lays down easy and i was able to print a flat fixture with sharp corners and good dimensional tolerances and high infill just copying over sirayatechs settings.270-105-60

This has got to be easily the worst experience with filament I've ever had.I didn't open this box until my Amazon return had already ended, and man do I wish I had checked when it arrived.Upon opening, a brand new sealed package, I was met with incredibly brittle filament. I contacted support, who told me to dry the filament for a couple of hours. They offered no other support, no other solutions. I dried it as directed, despite it being brand new, and while it improved some of the brittle nature, it did not improve it by much. Now, I'm trying to print with it, and finding that the spool itself is incredibly tangled, and seems to even be stuck to itself, despite using a proper filament drier. There's only seems to be on the left side of the spool, but I can't sit here for hours worrying about tangles and removing the entire left side of the spool.I absolutely hate this experience, and I'm up at 1:00 a.m., trying to finish a print that I have to keep reconnecting filament to because it keeps breaking, due to clogs, melted filament, and who knows what else.If this had worked, it would be great value for my money, but it didn't. When I can get it to print for more than 3 minutes, the performance looks great, but I can't tell you anything more, because I can't actually judge a partial print.

I use this ABS-GF on everything l can around the shop. Works great for fixtures and automation components. I keep several rolls of each color stocked. Definitely worth the price.

I printed this in my Bambu X1.dried to 12%, Bed Temp 100°, Hot End 260°, 30 hotend fan, 20% chamber fan. Nice and sturdy filament. This isn't a "pure muted black", this has a little bit of a shine to it, almost like a grey-blue color. The top is PolyMaker Carbon PLA, the bottom is ST CF/ABS, so you can see the color difference between the two.

filament was so brittle it never made it to the extruder. it snapped if you looked at it wrong. contacted cs and they advised to dry the filament. i used my dehydrator at 140 degress f and it melted. cs wont respond to me now. crappy product they do not stand behind but are more than happy to take your money. save your money buy something different.update:1/10/2025turns out it was a misunderstanding between myself and their cs rep. Mark Peng the founder contacted me and this is what he had to say...i actually missed this message and saw it later afterwards but they have made things right and i should be getting a new spool soon. i never replied to this message because i missed it but id like to reply here and say thank you for taking the time to clear this up and being willing to make things right. bumping this up to 3 stars and will re-assess after printing with the filament.________________________________Hi Ryan,This is Mark Peng, founder of Siraya Tech. I want to personally address this support request, as it was poorly handled by my teammate, and I’ve already reprimanded the new rep for this.What can I do to make things right? I’d be happy to replace the filament if you’d like.Additionally, the original reply wasn’t meant to suggest that you dry the filament, but rather to check if it might have been over-dried. We’ve seen similar issues with other users in the past. Unfortunately, the rep didn’t provide the full context or a proper explanation, which I take responsibility for.Let me know how I can help resolve this for you.Best regards,Mark Peng
