Review on 🖨 Precision-Engineered Printer Filament: Ensuring Dimensional Accuracy on Spools by Rick Alexander

The first time I tried using this on my Ender 3 V2 I installed an all metal MicroSwiss hot end but didn't change my firmware to get the temp over 260C (the highest) to keep factory temperature) and the results were, well, terrible. View three photos of the ongoing print. The filament is also frozen on my nozzle. I then modified the firmware to print following Taulman3D's instructions from their website. Nozzle temp 285-300°C, retraction = 3-4mm, bed temp 55°C. It worked great. I broke a wheel from our shopping cart, and instead of spending $30 for two (I only need one), I made the wheel out of Taulman3D Alloy 910 HDT and the "rubber" tires out of alloy. blue tpu. Printed with a layer size of 0.28mm so the wheel looks a little "rough" but function over form, it worked really well. Added two 608 press-fit bearings to improve on the original. Think about making a matching wheel for the other side. Maybe. Overall, this is a very good but challenging thread. For applications where you need high temperature resistance and/or sharp prints, this is a reliable solution. Highly recommended.
