Whenever you heard about the “Prusa filament”, it always referred to a product made for us by an external company (it is a common practice for all printer manufacturers). However, the new Prusament is manufactured in the very same building as our Original Prusa i3 3D printers. Twelve filament production lines are currently installed on two floors of our factory! In the manufacturing process, every detail matters – and we are paying great attention to every step. Every product is checked by our strict quality control. Filaments are shipped perfectly wound and carefully packed, so they retain the best possible properties when we ship them across the world. Plus, we do more than just manufacture. Our research and development teams are working on new colors and new materials, so we can expand our lineup with many new and interesting products in the future. We care, of course, about the environment as well – we have designed our own spool, which is not only durable and light, but it also needs 50% less plastic compared to commonly used spools.
Most filament manufacturers use a ±0.05 mm diameter tolerance when producing 1.75mm filaments. It looks like a tiny number, but we must not forget that this kind of deviation can in its extreme values increase or decrease the expected flow rate by 11.4 %. We decided to set our own manufacturing precision standards. We guarantee ±0.02mm precision for the vast majority of materials (±0.03 mm for blended materials)! The diameter is measured in both axes several times every second, so we can guarantee the maximum precision and best possible circularity of our filament. As a result, increased manufacturing precision leads to a lower percentage of unsuccessful or low-quality prints.
