Print settings conflict, prints easily, but shrinks and is brittle- unusable

I printed a mechanical piece that I had printed with PLA Professional. Using that filament, everything fit and worked properly. I found this needed 290 nozzle and 90 bed in a Creality soft-sided enclosure on an Aritllery X4 Plus S1 using it's PEI sheet with glue stick. I printed on the Y axis. At 280/80 one side of the base layer pulled loose when the oblong item was printed aligned on the X axis. I printed a .2mm layer height at 100mm/s with fans 20-60%, 2mm retraction @ 40mm/s and 100% infill. See below for print setting conflicts. I used this filament right out of the bag, as it says on the site not to dry it unless you have problems.Once the part printed, I was able to get the supports out relatively easily, and the surface while not smooth was decent. This portion was a marked improvement over the Overture Easy Nylon I tried before.I then removed an internal metal support from the same model in PLA plus and it would not fit into the same opening. I tried to push it into place and the front portion of the pocket cracked, turning the model into 3 pieces. This material is very brittle. A second larger metallic piece designed to be removable fit most of the way in, but jammed once seated. It easily pulls in and out of the PLA plus.I have deducted one star for various reasons-1. The print settings vary between what is on the bag (I got old stock marked PAHT) and what is on the website.2. The shrinkage made my item unusable. I'll have to experiment to get the enlargement right in Cura. UPDATE- can't be done, see below.If you go by the label on the bag, here are the print settings:Nozzle 280-300Bed 80-100Speed 30-220Fan 0-80On the spool, it saysNozzle 280-300 (same)Bed 80-100 (same)Speed 30-200 (slightly lower)Fan 0-80 (same)On their website (product page), it says this:Nozzle 260-280 (lower)Bed 70-80 (lower)Speed 30-120 (lower)Fan 20-60 (lower)On their website's user guide, it says this:Nozzle Temperature 280-300 (same as bag)Bed 70-80 (lower than bag, same as product page)Speed 30-120 (same as product page)Fan 20-60 (same as product page)UPDATE- Reduced to 2 stars. This material is just not suited for precision printing. I adjusted my model in Cura after measuring the failed piece and one that printed OK as-is in PLA Professional. I added 7% to X and 2% to Y and Z. I also reduced layer height to .16. While the support fit in the pocket this time, the locking pin that holds it in place would not go all the way through. It started on one side, and it ended up cracking in the exact same spot as before when I tried to drive it into place as designed- something PLA Pro has no problem with. I also found there was too much slack for the other part that fit into the model. Seems like nice material, but just not suited for what I needed it for. You shouldn't have to spend so much time dialing in shrinkage for such an expensive filament when filaments that are about 1/3 the cost don't have this problem.UPDATE 2- The seller contacted me and advised the website setting were correct, then offered to refund my money. Revised up to 5 stars, that is how to correct a problem.

Excellent for functional prints.

Awesome filament. My new go-to for functional prints even over PA-GF/CF. I’ve had zero stringing or clogging. Mechanical properties after printing are awesome. Very rigid but with enough flex to not be brittle. Printing has been a breeze with no warping or Shrinkage that I’ve observed at all. Dimensionally accurate with a good finish. Build plate adhesion is perfect on my smooth PEI plate with some CSR dream adhesive. Releases from the plate wonderfully but stays adhered through the print.The 1kg roll is so much more convenient than the .5kg roll that some others use. 10/10 will absolutely buy again

Amazing customer service and great filament.

Wanted to try this pet-cf after seeing good reviews on it but wow was it difficult to manage.I struggled with it constantly with how brittle it is to the bed adhesion. It stuck to the bed so bad that I ruined a plate trying to get it off.Honestly I wouldn’t buy this filament again.EDIT^I initially had a tough time with the Siraya Tech Fibreheart PET-CF filament, as it was brittle and had severe bed adhesion issues that even ruined a build plate. I shared my concerns in a review, and to my surprise, the company reached out to address the problem. They sent me a replacement roll, and the experience was a complete 180!The new roll came perfectly dry out of the bag, and it printed beautifully on a smooth build plate with minimal effort. The filament was easy to manage this time around, and the quality of the prints was top-notch—strong, precise, and with an excellent finish.Not only is the filament impressive when handled correctly, but Siraya Tech’s customer service is also outstanding. They genuinely care about their customers and stand behind their products. This kind of support makes a huge difference, and I wouldn’t hesitate to recommend giving this filament a try.

Fantastic engineering filament at a great price.

This is one of my favorite filaments. Very strong. Very stiff. Prints like a dream.I'm also leaving a review of the PPA-CF as well here since they aren't going to give me the ability to put in separate reviews for each filament. I use the PAHT-CF stock filament settings on Orca slicer with no changes to the filament itself other than temp (295C at all times). I don't change the flow rate, but I am running a Panda Revo on my Bambu P1S with a .6mm Obxidian High Flow nozzle. If you don't have a high flow nozzle, you might want to slow the flow rate down a little. It looks almost ordinary dark gray on the roll, but gets very dark gray when you print it. When properly dried, this stuff prints like a dream. Very stiff with great layer adhesion and it lays down beautifully. Other than the color, I like it a great deal more than the Bambu Lab PPA-CF and I will only be using this going forward. I like the inky black color of the Bambu filament, but it doesn't print as nicely and the layer bonding is considerably weaker than the Siraya Tech PPA-CF. I have only used part of one roll thus far, but if it is consistently like this, I will use it a lot and will be buying more of this filament. Absolutely phenomenal.
