PA6-GF25

First time printing with any nylon much less nylon with GF. I printed this on my Centauri Carbon and only took a couple small prints to tune it in using generic profile in Orca. The print had a great surface finish and the biggest surprise to me was how lightweight the item felt. The lightweight feeling almost makes you think the print is fragile but that couldn't be further from the truth! This stuff is stout! After print the items i went ahead and annealed the parts just using an old countertop oven at 230 degrees for 6 hours. Again this was a first for me. Was not sure what to expect after annealing but the part looked and felt the same although I understand that annealing really adds strength, durability and heat resistance. Over all it was easy to print. I couldn't really speak about how strong it is compared to other filaments but it feels really tough.

Easiest PA6-GF I have worked with

Easiest PA6-GF I have worked with. Printed amazingly well with just a few tweaks to the default bambulabs profile. Material was dry and ready to use out of the box and printed cleaner and faster than bambulabs equivalent. Will be ordering more of this for sure!

This PA6 GF25 pleasantly surprised me

This PA6 GF25 pleasantly surprised me. It's relatively easy to use despite being a technical material, it sticks well to the bed, and the spool has given me very few issues.
The glass fibers improve surface finish, layer lines are less visible and the overall look is excellent. It costs a bit more than some other nylons, but the finish quality and consistency make it worth it. For me, it’s 5 stars.

Very printable with Bambu A1 with hardened nozzle and in an enclosure

Very printable with Bambu A1 with hardened nozzle and in an enclosure. Printing with a brim ensures good bed adhesion. Makes tough parts.

Great finish

Inslogic PA6-GF25, in a direct comparison of models printed on the same Bambu Lab H2D with the Inslogic vs Bambu Lab PA6-GF, the Inslogic version is visibly better in finish and hiding layer lines. The Inslogic PA6-GF25 will now be my goto PA6 filament. Very impressed!
