My favourite rainbow matte PLA filament is 20% off right now

May 16, 2025

Looking for some beautiful multicoloured 3D printing filament? I’ve been using iSANMATE’s Matte Rainbow PLA recently, and it’s on sale right now for only $23.99 over at Amazon for a 1KG (1.75mm) spool. That’s 20% off the usual $29.99 price tag, which is a pretty rare and generous discount for a filament this high in demand (I’ve seen it sell out plenty of times before).

I’ve been 3D printing some awesome models over the last few weeks with my Bambu Lab X1 Carbon, including a beautiful baby Cherry Blossom Dragon from popular designer, Cinderwing3D using this rainbow filament. After subscribing to Cinderwing’s membership via Thangs, I was overwhelmed by all of the stunning models and just knew I had to print a pretty dragon with this very pretty filament (take a look at the image below and tell me it’s not adorable).

If you’re in the UK, there’s no need to feel left out. You can bag 16% off the iSANMATE Matte Rainbow PLA Filament, which is only £18.39 per 1KG spool, right now at Amazon. I paid around £20 for this filament last month, so while this isn’t a huge price drop, it’s still better than nothing, right? Trust me, this filament is GORGEOUS in person and I’m so impressed with the results. Take a look at our guide to the best 3D printers if you want to create your own pretty pastel dragon.
