Ultimate Toughness and Weather Resistance for Superior 3D Printing
Color: 1000g Asa Black
Size: 1kg
The SUNLU ASA Filament has been great for my 3D printing projects! I recently started using this filament for some outdoor and high-temperature applications, and it has truly exceeded my expectations in every aspect. First off, the toughness of this filament is remarkable. It’s incredibly durable and resistant to UV, rain, and heat, which makes it perfect for prints that will be exposed to the elements. I’ve noticed that prints made with SUNLU ASA hold up beautifully under various environmental conditions, maintaining their strength and appearance over time. The filament feeds smoothly through the printer, with consistent diameter and no issues of clogging or jamming. This has made for a hassle-free printing experience, resulting in high-quality prints with excellent layer adhesion and fine detail. What really impressed me was the filament’s resistance to environmental factors. I’ve used it for some outdoor projects, and the prints have held up wonderfully against sun, rain, and temperature changes without any noticeable degradation. Overall, SUNLU ASA Filament offers outstanding performance and reliability, making it an excellent choice for any 3D printing enthusiast looking for durability and quality. It’s definitely earned a top spot in my filament lineup, and I highly recommend it for anyone needing tough, weather-resistant prints!

Very Nice Filament That Looks GREAT! Easy to print.
I really like this filament a LOT! It's super easy to print, and looks fantastic! The cost is very competitive, and the parts feel strong. Most of the benefits of ABS, with the ease of printing of PETG, and very low odor.

Great filament, reliable and consistent
Color: 1000g-asa Grey
Size: 1kg
Prints beautifully on the Bambu P2S. No print quality issues with it. It was well-packaged and there were no issues with delivery damage. No stringing or other troubles with this filament (yet) and I have run several jobs through. I run my printer 24/7 and need reliable filaments. I have run several jobs with this and have had no troubles and did not have to apply any non-default settings in the slicer. I will definitely purchase this again.

Quality Filament
This has become my go to filament for functional prints. The strength and durability of this filament is great while printing flawlessly. I've had good success with printed flexures and load bearing prints using this material. I print on an enclosed 3d printer, so I cannot speak to the was of printing or print quality on open printers.

Pretty good value for ASA.
FlashForge is my preferred ASA, but I wanted to try a slightly less expensive product and decided to get the Sunlu. For me, in my Bambu Labs X1C, the only difference between the two filaments once calibrated is that the max flow rate is lower in the Sunlu, approximately 20mm^3/s vs the 29mm^3/s I can drive the FlashForge at. Other than that, the adhesion is fine on my textured PEI plate, without glue, and not as good on the Engineering plate with glue. Parts are as strong as other ASA and ABS that I have tried. It off-gasses like all other ASA when printed so it needs ventilation, and it does warp as it is still ASA, but brims and mouse ears help with warping issues, keeping the parts on the plates.

Terrible Filament
Color: 1000g-asa Grey
Size: 1kg
This is by far the worst quality ASA filament I have ever used. I have printed hundreds of rolls of flahsforge and bambulab with no issues. This stuff literally will crumble in your hands. Major layer adhesion issues during printers with parts splitting in half mid print. I can literally rip pieces a part with my bare hands. Tried different settings, different machines, with no improvement in results. Returned my unused rolls. Will never buy again.
