Review on BuMat Printer Filament 1.75 Blue: Superior Quality for 3D Printing by Fritz Wiest

Revainrating 5 out of 5

Very durable and usable when printed correctly

As expected, printing is more difficult than ABS+ and similar materials because the adhesion to the layer (pure PEI) is not strong enough at temperatures below 105-110 degrees. with bed at level 105 and nozzle at level 255. Photos show recent printing, usually difficult with ABS (high angles, moving bed, no enclosure, 25°C ambient). Artifacts due to lack of pressure and a shaky Z-axis are not characteristic of the filament. Really good strength and adhesion of the layers at the moment. Unlike some other ABS/ABS+, it automatically separates from PEI on cooling, requires no peeling (ABS+ is notorious for sticking too well and requires tools for thin objects, even on flexible sheets), but also requires a much higher temperature for good adhesion of the layer / reduction of denting). Compared to other more neutral colors, gray has a distinct blue cast.

Pros
  • 3D Printing Filament
Cons
  • Wrinkled
