In this video, I test and compare three nylon-based 3D printing filaments from Sunlu: Easy PA, PA6-CF, and PA12-CF. I go beyond just printing them — these materials are analyzed through a full series of mechanical tests, including tensile, impact, shear, torsion, bending, creep, and thermal resistance.

I also check for printability, brittleness out of the box, layer adhesion, and dimensional stability after annealing. If you’ve been wondering whether Easy PA is a budget winner or if one of the carbon fiber-filled nylons is worth the extra cost, you’ll find the answers here.
