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)

Filament arrived in good condition and sealed. I still dried it as I do ALL my filament. Printing with great results and very good finish appearance. Overhangs require slowing down and some part cooling fan. I've had no issues with bed adhesion on standard textured PEI build plates at 90°. No issues with warping in my enclosed X1C machines with the chamber temp staying around 42°-44°. Printing with a 0.4mm hardened nozzle and no clogging.No scientific testing but the finished prints seem to be very strong and durable.This is my new goto filament for ABS-GF.

The media could not be loaded. I can’t say enough good things about siraya tech’s filament. This ABS-GF has printed excellent for me with 0.4mm nozzle using the Orca Slicer profile that Siraya tech provides on their website for my Qidi plus 4. Very first prints came out perfect. I have also used their CF-PET with great results but the ABS is a more affordable option with high temperature resistance and great layer adhesion and strength. I have not yet experienced any warping or stringing or anything really. Even longer bridges and overhangs come out great as you can see from my photos printed without supports. I have left this abs-gf out in the open in my 40% humidified home for a few weeks and I have still not had issues with moisture. My PETG on the other hand would be extremely stringy by now. The ABS-GF does have a bit of ABS smell for sure but it’s not as strong as some others i’ve tried in the past. This might be my new go-to filament instead of PLA. The surface is slightly abrasive, not quite as much as the PET-CF but the parts look almost identical. I noticed more skin irritation with the PET-CF. This ABS-GF does not seem to bother my skin at all really unless i’m cutting or sanding on it. The ABS GF is still quite flexible like regular ABS but a little less, since it’s only 10% glass but that also means better layer adhesion and less abrasive surfaces. I think the flexibility is close to PLA, but the filament itself is still pretty brittle. The PET-CF is a LOT more stiff and also more brittle but INCREDIBLY strong. The CF-PET, for example, I had a thing piece of support material maybe one or two walls thick, and when trying to bend it, it was incredibly strong. When it finally broke it exploded and have my finger a little cut. I hope to see more colors come out in the future. I would love an ABS-GF in Purple.

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

(ASA_GF) I started with the generic ASA profile, then put in some data from the Siraya Tech website (which is actually really good). I ran the flow ratio and pressure advance tests to dial it in and man does it print perfect.The low 10% glass fiber content in this filament seems to be the ideal balance vs 25% filaments. It's not all rough like some of the others I have used, yet it still has the rigidity from the fibers.It seems like Siraya Tech filaments are a premium product and not just another random brand.

I create firearm products using ABS-GF filament, primarily Bambu ABS-GF, due to its impressive strength and durability. In product testing, I’ve even run parts over with a car, and they show little to no compromise. Compared to PETG-CF, ABS-GF offers significantly greater strength. Before anyone attributes this to print settings or machine quality, let me clarify: my Ender 3 days are long behind me. I now operate a Bambu X1 Carbon with settings meticulously optimized for production. Additionally, I perform detailed tuning for all filaments before using them, whether for commercial or personal projects.When Bambu ABS-GF was out of stock, I tried Siraya Tech's ABS-GF filament in black as an alternative. While the print quality is comparable to Bambu's, the strength is disappointing. Parts printed with Siraya Tech filament snap with minimal effort—almost like a dry twig. In contrast, Bambu's filament takes significant force to break, often requiring a real struggle by hand.This weakness is also apparent during automated material switching (AMS), where Siraya Tech’s filament snaps whereas Bambu’s filament has never snapped. If returns were an option, I wouldn’t hesitate. For anyone seeking a filament with robust shear strength, this product isn’t for you. If the shoe were on the other foot, I would leave Bambu labs the same review. However, this stuff is very weak. I expect my prints to be both visually appealing and exceptionally strong, but unfortunately, Siraya Tech's ABS-GF fails to meet the mark.

This filament looks great when printed, I will continue to use it when strength is not needed.the good:- excellent prints- supports just fall awaythe bad:- very brittle so mechanical parts are not effective- if you are using a bambulabs AMS the initial spool is to thick to fit. after you print 10% of it you can use it.conclusion:pretty but not functional
