Review on 🌈 Revolutionize 3D Printing with Color Matrix 1 Additive Manufacturing Products by Dustin Keller

Overall I thought this refillable coil idea was a good idea. The company sells spools and these refills. The spools come with some tools that allow you to easily and quickly replace the used spool with a new one. The exchange is easy in my experience. The color itself is nice, the thread works well. I'm not sure how to tell the difference between PET and PETG during printing (or even after) so I can't say if PET itself is anything special. It printed well, albeit with no issues, so I don't have any major flaws. The only drawback would be the price. I assume that a spare spool without a spool will be a lot cheaper than a spool with a different filament. It's more expensive, but also comes with non-roller refills. While it's nice, I wonder if it's worth the effort - they have to work really hard to convince me. I may buy others in the future as the color came out well here. Recommended with this limitation.
