Review on 🎨 Vibrant and Versatile: SAINSMART Colors Small Spool - Flex Your Creativity with Multicolored Filament by Robert Aliraqi

I received a pack for the promotion. Otherwise these small coils are not cost effective. The filament prints well at 40 mm/s, 210 °C and bed temperature. I'm printing with an Ender 3 modified with a BMG direct drive installation. One of the vacuum coils was not fully sealed, which is having a negative impact on print quality. Unlike other colors, it stretches a lot. Conclusion: quality thread, slightly overpriced. If you are looking for something cheaper but high quality, try Yoyi TPU. Updated 5/25 This TPU is highly hygroscopic, which means it absorbs moisture quickly, which will adversely affect your prints. I store my filaments in a ziplock bag with desiccant and then store them in a plastic container with a lid. The indoor temperature of my house is 72F and the humidity is 45-50%.
