Black CoexNylex™ Unfilled Nylon
Unfilled Nylon, Black in color. CoexNylex™ combines outstanding heat resistance with chemical and hydrolysis resistence
CoexNylex™ Nylon is manufactured from the highest quality nylon developed by Dupont. Coex Nylex is able to be printed on most 3D printers to produce extremely durable and strong parts.
.
Recommended print settings:
- Print on a solvent-cleaned surface heated to 85°C-110°C
- Recommended print temperature 245°C-295°C
- Part cooling fan is not recommended. It may cause layer delamination.
- Start retraction at 1-1.5 mm at 10-30 mm/sec for direct-drive extruders and 2.5 mm at 30-35 mm/sec for indirect-drive extruders
