METAL BRONZE our 80% bronze filled filament which is easy to print, sand & polish. With MT-BRONZE you can create the most beautiful objects with real METAL characteristics, such as a 3 x higher weight ten PLA, a METAL feel & touch and thermal conductivity. Due to the high percentage of fillers, MT-BRONZE has virtually no shrinkage, a special lubricant increases the flow and prevents MT-BRONZE to adhere to the nozzle. Finally, all above combined with the correct hardness results in a filament that can be printed on almost every type of FDM 3d printer available on the market with retraction enabled on nozzles ≥0.35 mm.
