First print after calibration using Siraya Tech PET-GF in FDE. Print came out nice and is surprisingly strong at only 25% gyroid infill. I used 8 walls with 6 top/bottom layers. Printed at 300C nozzle with 80C bed on a Bambu P1S using a Darkmoon CFX build plate and printing from a 60C dryer. 0.4mm nozzle at 0.16mm layer height. One nice benefit to this filament is it comes completely dry and ready to print with Siraya Tech even warning not to dry it unless its needed at the filament has a low moisture absorption rate.

Looks good! I really don't have a need for PET-GF right now, but $34.29 with free shipping?! That's just too good to pass up.

I was recommended it by another user and im glad they did, for the price its a great filament that has quite a bit of use cases. When annealed it can withstand 210-250F and per grok with 10 walls, 10 top/bottom layers, and 100% infill it should withstand 1-2 meter drops on hard surfaces with only scuffs. I'll be testing that part out when I design some Gen 1 NV housings. The common con I hear about this filament is that its brittle but it seems to have some serious strength so time will tell. One more upside is its low moisture absorption.

I think your HDT numbers are Fahrenheit. Siraya's datasheet says 122°C annealed (78°C without annealing). Impact strength isn't great and it's worse if you anneal it, but there's still plenty of stuff it can be used for.

Yeah my bad, it's 210/250F or 100/120C depending on annealing method.

That looks really clean. I'll have to try some out. Been mostly playing with their ABS-GF lately.

I have my printer in my bedroom so I've been trying to stay away from ABS and other filaments that aren't as safe to be breathing in. I plan to make a fume extractor though. How does their ABS compare to other brands?

I plugged their settings into the bambu slicer and it printed great.

Haven't tried any other ABS with fibers in it. Don't print much ABS in general because I don't like the amount of flex in it. The ABS-GF is nice and stiff. Simpler to work with than the higher end engineering filaments. Saw it for sale one day and decided to roll the dice. A few kilos later it's my go to for stuff in the truck. Haven't tried anything like vapor smoothing it yet either.
