Review on 🔬 SainSmart Flexible Filament: Ensuring Uncompromised Dimensional Accuracy in Additive Manufacturing by Travis Rogers

I didn't want to try using TPU on my Anycubic Chiron because of the horror stories I've read online about it clogging, stretching, giving bad results and have to constantly play with Cura settings. I swallowed the bullet anyway and decided to give it a try. The first thing I print with every new filament is the XYZ calibration cube. After my research I set Cura to print at high resolution, low speed and recommended temperature (0.01 resolution / 25 speed / 215° nozzle, 60° bed / 100 fill). I crossed my fingers and hit print. The result was a perfect print that surpassed my PLA prints (see image). The black cube on the left is PLA and the pink cube on the right is SainSmart TPU. The TPU resolution is excellent, there were no stretch marks and the corners were sharp, unlike the PLA cube which warped letters and corners slightly. Even better ending. It has a softer, less shiny appearance that makes layers less visible. Since I printed with 100 infill, the cube is relatively stiff and doesn't flex, but you can tell it's made of rubber rather than plastic. An object with thin walls and little to no infill is undoubtedly more flexible. For a first print try, I'm very impressed.
