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 our PLA Prime, our high performance PLA 3D printing filament.


CoexFlexTPE and TPU filaments products offer you a variety of hardness ratings to give you the exact filament for projects that require flexibility but also resistance to shock and abrasion.  It will allow you to produce items that will be outrageously strong but still give flexibility to the finished product. 


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.
