PLA filament is compatible with a broad range of typical 3D printers; simply choose a higher printing temperature to guarantee smooth printing. The filament diameter tolerance is 1.75 mm + / – 0.05 mm, and it has a particularly designed superior wrap to prevent jamming.

Pros: This filament really does change colors quickly. And it’s lovely and glossy and comes in a rainbow of colors.

Cons: The overall length of each color is relatively little, and if you’re using a 3D printer with a Bowden-style extruder, like an Ender 3, there’s quite a length that’s in the tube between the extruder motor and the hot end, so you won’t have a lot of filament to actually print with until you combine the lengths together. It’s not TTYT3D’s fault that there are tutorials on YouTube explaining the process.

Pros: Great values for someone who doesn’t want to buy just one color. Since most people believe that better quality comes at a larger price, the quality is superb and far superior to the $30 brand now available. That’s not always the case, though, as this filament cost barely half as much while being of significantly higher quality than the $30 brand.

Cons: The filament may not exactly match the image because it is a random rainbow of colors. A large print size is also advised so that the color change will be more noticeable.

The entire color cycle of this filament is completed in around 110 grams of material. To put it another way, a 110g model will print with every color and will end up being almost exactly the same shade as it began. To put it another way, one color change should occur roughly every 22g.

Pro: When printed, the colors on this spool look amazing. The color change happens quickly enough but not too quickly that it oversaturates the print. With this rainbow filament, you rarely get adhesion issues.

Cons: Based on some reviews that the spool was full of knots. The colors look great like some brands, but there was a lot of untangling to do. The filament was so twisted and tangled that it broke halfway through a 16-hour print. So be careful—beautiful, it’s but it’s a mess.

  • Quantity: One Spool Packed in One Box, Spool Filament Net Weight is: 1kg(2.2lbs)

Cons: Some folks may be dissatisfied by the brightness or lack thereof. The colors are far darker than those on the Amazon list. When the spool was used for more layers, human fingerprints became visible. The filament is also brittler than typical PLA filaments.

Pros: Adhesion was ok

Complete drying for 24 hours before packaging and vacuum sealing with desiccants in a clear bag with no bubbles and easy to print. Full mechanical winding and careful inspection by hand, to make sure the line is neat and doesn’t tangle so that it doesn’t break.

Pros: It printed out very smoothly without issues
Cons: There isn’t much change in the colors. Some customers printed a vase, a trash can, and some fidget toys for the kids, and almost all of them were blue. It was a good product, but it was hard to get a true rainbow effect without a huge print.
