ABS Filament

Coex makes ABS filament with a diameter of 1.75mm and 2.85mm in several colors. ABS is great for many 3D printing applications that require more durability and heat resistance than PLA such as prototypes or functional parts. ABS can be more difficult to print than PLA, though ABS is still a very popular filament for professional 3D printers. ABS is more resistant to impact and high temperature (between -20°C and 80°C) than PLA. Parts printed with ABS appear opaque, smooth, and shiny. ABS parts can be welded together through chemical bonding using acetone.

It is strongly recommended that ABS be printed with an enclosed 3D printer. ABS can emit particles that may be dangerous for the user. An enclosed printer will also shield from drafts and allow ABS parts to cool slowly and more uniformly, helping to prevent shrinkage and warping.

Coex makes its ABS products with only high quality virgin resin and colorants. All of Coex's filament is made in our production facility in Wisconsin, USA and we use industrial grade extruders and laser measuring quality control. We provide filament that gives excellent looking & strong prints.

Our Resins

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.

Our Grades of Materials

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.

Our Quality Control

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 Facility

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

Our Process

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.
