Collection: ASA Prime

Our resins are sourced from suppliers committed to high quality standards. Our partnerships with these suppliers ensures we maintain quality and consistent filament batch after batch. We only use prime virgin resins, colorants and processing additives to ensure reliability.

We believe in our filament so much, we often tell customers to start with our base filaments and compare them to the other makers higher grade filament. But we didn't stop with a great base grade, we also offer Prime in our PLA and ABS lineup. Prime is a more refined resin which improves print quality and strength.

We quality control the entire process of our filament. Starting with an incoming inspection process, we verify the resin is the quality we expect. Precise temperatures are monitored during extrusion. Laser measuring ensures our filament is held within a .03 tolerance. Final visual inspection for color and quality ensure you are receiving our best product.

Our climate controlled factory ensures dry material throughout the filament making process. Once the filament is spooled, each roll is vacuum sealed with desiccant inside the bag to prevent moisture. More hygroscopic materials go through an additional drying process in both the raw resin and then again once spooled, before being vacuum sealed

We use industrial-grade extruders which melt and mix our resins with colorant, which is precisely fed at a consistent rate, via gravimetric color feeders.

Once melted and uniformly mixed, the resin is pushed through a heated die and fed into a warm water bath, which quickly cools the filament.

An industrial filament puller maintains the filament diameter, by speeding up or slowing down, based on readings it receives from the laser measuring head. The laser measuring head not only measures the diameter, but also the ovality, or in our case, lack thereof.

Our winding machines then spool up the filament with a traverse feeder, which ensures an even flat winding. This also ensures that it cannot overlap filament and cause a tangle.

Our finished spools are post-dried in our walk-in oven and then immediately vacuums sealed with a desiccant pack to ensure you receive dry filament.
