Collection: CoexNylex™ Nylon 3D Printer Filaments

CoexNylex™ Nylon 3D Printer Filaments

CoexNylex™ nylon 3D printer filament is manufactured from the highest quality nylon developed by DuPont.  All of the CoexNylex™ filaments create extremely durable and strong parts for heavy-duty uses.

Excellent strength and stiffness with outstanding heat, chemical and hydrolysis resistance. CoexNylex™ nylon 3D printing filaments feature excellent printing characteristics including good printing speeds and lower moisture absorption than PA6 copolyamide, so you’ll get less variability during printing operations.

CoexNylex™ 3D printing filaments have a heat deflection temperature in the range of about 100-110ºC, resulting in lower warpage and shrinkage and print with an outstanding surface finish.

CoexNylex™ durable 3D printer filament (as well as other Coex 3D products) was featured in a great independent analysis of the strength of various 3D printing filaments by Nathan Tsoi. Check that out here on Nathan's website!

Learn about our 3D Printing Filament

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.
