Review on 🖨️ Revolutionizing 3D Printing with MIKA3D's Silver Copper Filament Printer by Chase Dunn

I bought both the different packs of 'High Gloss' and 'Silky Metallic Gold' so this review reflects my experience with both Mika3D PLA types reflected. filament.UPDATE: I continued to struggle with under-extrusion/filament jamming, especially when printing finer detail with the 0.25mm nozzle. Luckily I just found a setting in PrusaSlicer that seems to have solved this problem by limiting the maximum flow/pressure. By setting the "Maximum Volumetric Speed" I can prevent the extruder from trying to push too much filament through too quickly and avoid fragile filament from breaking in the toothed pin grooves and eventually slipping off. Prusa suggests a default value of layer height × extrusion width × speed. My Prusa Mini with the upgraded Bondtech extruder and a 0.25mm nozzle is currently printing at a maximum volumetric speed of 0.75 mm³/s and shows no signs of under-extrusion. It's conservative and I plan on testing higher flow rates as it's almost doubled my print time, but if the other option is wasting time frustrating over print failures and extrusion issues, or over 20 different rolls of Mika3D filament throwing away that I bought, I consider it a victory. --- FIRST REVIEW: After dialing in my settings for good bed adhesion (configuration below) I have been very happy with this filament for larger items with low detail like toys and clips. The main difficulty I have found with this filament is that it is too brittle for the extruder gears to repeatedly move back and forth for detailed work. Every time I tried to print at 0.10mm or less. The first few layers print well with fine detail (0.05-0.10mm), but as the extruder gears move the filament back and forth, the sides break off and collect in the extruder gear teeth. This results in less grip and more friction in the same place. Eventually the thread stops squeezing and when I unload it you can see where the sides are being ground down to a bottleneck where the gears no longer have enough grip. It is worth mentioning that the temperature tower I printed (see photo) showed consistently good quality between 190°C and 215°C, with significant fluctuations from around 220°C. Original Prusa i3 MK3S (PC bed) Recommended settings: Layer height: 0.15 mm or higher Extruder temperature (first layer): 230 °C Extruder temperature (others): 215 °C Temperature (first layer): 80 °C (others): 70C
