Review on 🎨 Mika3D Version 1 by Amicz Kakaruk

I bought both the High Gloss and Seid Metallic Gold kits so this one is reflective Rating reflects my experience with both Mika3D types. PLA thread. UPDATE: I continued to have underextrusion/blocking issues with this filament, particularly when printing finer detail with the 0.25mm nozzle. Luckily I just found a setting in PrusaSlicer that seems to solve this problem by limiting the maximum flow/pressure. By setting the "Maximum Volume Velocity" I can prevent the extruder from trying to push through too much filament too quickly and prevent brittle filament from breaking in the grooves of the toothed bolts and eventually slipping off. Prusa suggests a default value of layer height × extrusion width × speed. My Prusa Mini with the upgraded Bondtech extruder and 0.25mm nozzle is currently printing at a maximum volumetric speed of 0.75mm³/s and shows no signs of underextrusion. 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 failed prints 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've been very happy with this filament for larger items with low detail like toys and clips. The main difficulty I had with this filament is that it is too brittle for the extruder gears to constantly move back and forth for detail 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's worth noting that the thermometer I printed (see photo) showed consistently good quality between 190°C and 215°C, with noticeable fluctuations from around 220°C.
