Rainbow Magic!

Are you tired of your plain old filament? Bored of watching the same colour print layer on layer? Well, have I got some news for you! Today in this article I’ll be reviewing and writing about Eryone Rainbow PLA Filament.

What is it?

Pretty much everybody here at Inov3D has used Eryone, the online 3D printing company. They offer their own brand of filaments for 3D printing, marketing towards well, everyone.

As for the product, Eryone hasn’t skimped on quality. Boasting a plus or minus 0.05-mm precision, and “no clogging, extremely high success rate”, which makes this PLA filament sound really impressive.

The Eryone Rainbow PLA is offered as a 1-kg spool, in a 1.75-mm diameter. The colour of the spool circulates throughout, Red-Orange-Yellow-Green-Blue-Purple-Red. Although the first colour is random. In my case the first colour was purple.

The price of a 1-kg spool of 1.75-mm PLA is £25.99.


I tested out the Eryone Rainbow PLA on a Creality Ender 3. The spool came the next day packaged in a small recyclable cardboard box. It was sealed in a plastic bag with a silica desiccant pouch to avoid damage from humidity but it would have been nice if the bag was resealable, so the filament can be stored when not in use.

My test prints were all completely successful, and the prints have a silk finish, which makes them look shiny, and with a smooth feel to the surface.

The color is very vibrant and really “pops”, exactly described in the description. I noticed that light does slightly get through, probably based on the thickness, which could make this an interesting material for lithophanes (if you want your pictures in rainbow, that is).


The first test print was “Skully” by armourcraft. There were no obvious issues with quality, aside from some very slight, almost unnoticeable bumps on the back.

My second test was the “Unicorn Trophy” by Apachcreation. This was to test how the filament would show flat surfaces and to see the gradual colour change. The model for this came out perfectly but there were some layer gaps, which was the fault of my Ender 3.

The final 2 models I printed were, “Sir Flexington Rexington” by tom_sky and my personal favorite “Overwatch Pachimari” by Oaklandishh. Flexington was used to test the accuracy of the filament and came out perfectly, and is the best Rexi i’ve printed so far. The Pachimari was more of a personal print to keep but to also test the gradual colours again. The Pachimari came out perfectly but again had layer gaps like the Unicorn.

The photos below prove that the layers are very consistent and adhere to each other well. The dimensions are accurate and the details turned out very well across all models.

Since this is PLA, it will print pretty easily with most basic PLA profiles. Changing some settings such as infill and model scale can create some amazing designs. Which I will post some of our communities models at the end.

I printed using a “Generic PLA” and “0.2mm Quality” setting in Cura, but changed the following:

  • Nozzle temperature: 215 °C
  • Bed Temperature: 60 °C

The specifications on the box are as follows:

  • Nozzle temperature: 190–220 °C
  • Bed temperature: (not required)
  • Filament diameter: 1.75 mm
  • Tolerance: ± 0.02mm

The Conclusion

The Eryone Rainbow Filament is an amazing PLA for the price. I used it for most of my prints now because I love all the colours. It was very simple to use and I 100% recommend this to anyone and everyone. All generic 3D printers and pens can use the filament with no issues.

Of all the models I’ve printed there has been no issues with the filament. The plastic itself is not brittle and had no flaws. Delivery was fast as expected and the packaging was pleasant with minimal waste. Overall I couldn’t find anything wrong with this product and will definitely be returning in the future for more Eryone products.
