Siraya Tech Fibreheart PET-CF 3D Printer Filament, High Strength, Black 1kg

gekocht voor 31,57 om te testen en het werkte prima dus eigenlijk 5 sterren maar wilde het een week later weer bestellen maar was toen ruim 21 euro duurder. Vandaar maar 3 sterren. Moet nu weer op zoek naar een ander merk met wel een fatsoenlijke prijs of wachten totdat de prijsverhoging ongedaan gemaakt wordt. De huidige prijs op amazon.de is nu 37,99 daar zou ik het ook nog voor gekocht hebben.

While this review is technically for the CF since that’s the order I selected to review, I’ve purchased both the black PET-CF and the FDE PET-GF from this listing. I like them both. The GF is a dream to print. Every bit as easy as PLA. I had problems with the CF and I think others have had the same problem with an excessively brittle spool that snaps in the feed tube, but I was able to fix that. I use a Centauri carbon with a .6mm nozzle and print directly from a Sunlu S2 dryer. First of all, SirayaTech says to NOT dry the filament right out of the bag. They say that they dry the spools before packaging and that too high a dry temp can initiate the annealing process and make the filament unprintable, so I took their advice. Like I said the GF printed flawlessly but the CF was horribly brittle. Siraya also says to dry your spools if you have problems, and after about 18 hours in a food dehydrator at 60c it’s printing just as nicely as the GF. But Siraya also says to print this stuff at 300 and that caused stringing so I’m running it at 295 with much better results. So if you’re having problems with the CF breaking excessively, dry it low and slow. I put mine in the dehydrator before bed last night, took it out once I got home from work, and loaded it into my Sunlu S2 for printing. So far so good. I’m halfway through the print and no breakage. Last time I tried printing this filament it broke on like layer 12. I’ll add that I also turned the speed way down, cutting it roughly in half in the slicer and then running the whole print on silent mode. Seems to be working great now and so far I’m extremely impressed with Siraya’s filaments. Great materials at a very reasonable price. I’ll be really interested to test this stuff head to head against another one of my favorites — Sunlu’s carbon and glass filled PA6. I think this Siraya PET and the Sunlu PA6 are both incredible values when it comes to high performance filament. The obvious advantage of the Siraya reinforced PET is that it’s almost as easy to print as PLA. I’ve never had issues with it tangling and the finished prints look fantastic.

Muy rígido, buena adhesión entre capas, fácil de imprimir… Lo tiene todo, hasta el acabado es bonito, un poco rugoso. Imprimiendo a 290

This is the first PET CF filament I tried so I cannot compare it to others. All I can say is the resulting prints are very tough and rigid. Dry, dry, dry, absolutely necessary with this filament as you're no doubt aware. Straight out of the vacuum sealed bag it was pretty good but after a day the prints were rough. Heated dryer was purchased (Creality Official Space PI Filament Dryer Plus) and this resulted is perfect prints. Attached pic, two bottom components printed from freshly opened bag. Top after drying for 12 hrs at 65 deg C. Note the glossy textured finish and lack of layer lines, its actually better than depicted. The print between opening the bag and drying the filament went straight into the bin, ragged and rough. This was circa 12hrs exposed to UK cold and humidity. I thought I would try and pull the print apart to see just how strong it was, absolutely no chance. It opened up a little at the clamping end but went no further. Overall, great value for money, print using the specified parameters, keep it dry.

Das Filament wurde auf einem Prusa CORE One + mit einer DUROZZLE Diamant PCD 0.4er Düse auf einem Prusa Satin Sheet gedruckt. Die Oberfläche ist typisch für Kohlefaser gefülltes Filament, die einzelnen Schichten werden sehr schön durch das Material verdeckt. Die Druckhaftung ist hervorragend! 290° C Extruder-Temperatur 70° C Bett-Temperatur Über die mechanischen Eigenschaften kann ich bis jetzt keine Aussage machen, scheint aber vielversprechend.
