AlifiFilament for 3D Pen & Printer (Special Colors)

I have bought 2 packs of this. The red and green from 1 pack are garbage and snap when you bend them slightly. The Blue is flexible but full of air pockets and can hear it sizzling when going through the printer. It produces a horrible surface finish.The other pack the red is again garbage, the green seems fine, the blue still produces a horrible surface finish.To ensure its not simply my settings or bed leveling, i started a tall print with the blue filament and paused it half way, swapped to a known good filament and continued the print. There was a distinct difference between the 2 filaments even with identical settings.Its super cheap so not 1*, but wouldn't recommend for final prodcuts.

I was happy with the colors but surprisingly the quality is very very low. I tried adjusting the temperature and it still didn't work. The finishing result is so ugly and weak. I also heard something like bubbles when using it.I will probably return it since the item TOTALLY does not match the description they wrote which is "High Quality: Strict production standard to guarantee high accuracy. Eco-friendly with high performance, no bubble, no jamming, no drawing. High Compatibility: The filaments are universally designed and compatible with 3D Printers and 3D Pen. using 1.75mm diameter filament, with a dimensional accuracy of +/- 0.03mm. Print Temperature (190-220 °C) : Give you the smooth prints which require less calibration and give off fewer extruder issues."I didn't see any of this

I read those low ratings review but decided to give it a try anyway. Package came on time and in vacuum sealed plastics, looks convincing. So I put it on my few days old Creality Ender V3 which flawlessly printed several items before in stock settings. First I put the orange filament and print something. Only after the first layer I hear clacking sound and the filament is not extruding anymore. I knew this means the hot end is clogged. So I clean the clog. Next I tried the green filament. Same result, even worse, the PTFE bowden tube is clogged so bad that I have to 'amputate' it. I like the idea of having small 'samples' of different filament types/colors like this package, but the quality needs to be maintained. Thanks.UPDATE: it finally works with the following settings - Speed max 30-50mm/s, temp 210 degree Celcius.

We were excited by the nice fluorescent colors and were eager to try the bright orange one. However it was already broken into six or seven segments in the pack. It was so brittle that it easily broke at the slightest bend of even 30°.I have since read that the filaments need to be kept airtight and out of sunlight. These were probably not stored in good conditions prior to being shipped to customers like me.I tried taking one of the longer lengths and printing with it but it kept snapping during the printing process. It would clog up the feeder and required dismantling of tubing to remove. Upon inspection three of the five packs were very brittle and broken.Two of the five seemed a little bit better but had breaks. We are going to have to return the whole set of five filaments.

Works well with 3D pen

Very bad quality and i throwed it away as it is useless

Fine quality

Please don't buy this filament it can glow but can't write in 3d
