Coex’s PLA filament is the most environment-friendly 3D filament solution. Because of its low toxicity, our PLA filament is a very popular choice in the 3D printing community.  Also available is Coex’s PLA Prime, a high-performance PLA 3D printing filament.


CoexFlexTPE and TPU filaments offer a variety of hardness ratings to give you the flexibility and resistance to shock and abrasion needed for any project.  It allows you to produce a finished project that will be super strong but still gives the flexibility required. 


Coex’s ABS filament is a thermoplastic 3D printer filament that easily molds when heated and sets evenly when cooled.  It is used by a variety of manufacturing industries for parts requiring structural integrity and detail and is ideal for “wear and tear” projects.


Coex’s PETG filament is known for its durability and ease of use.  It is often described as the “best of both worlds” because it has the rigidity and mechanical properties of ABS but is still easy to print like PLA. It makes a popular 3D printing material for many reasons.
