Nylon Delamination and Pliability Test Object

thingiverse

This simple six-sided object, measuring 50mm wide by 114mm tall, is printed in 618 nylon copolymer for testing delamination resistance and pliability. It's printed hollow at worst-case settings to ensure that stretching occurs before any delamination of thread-to-thread bonds. The object is printed using specific settings on a 2BEIGH3 printer: temperature 240°C, nozzle diameter .052, layer height 0.26mm, and speed 36mm/s with one perimeter and one solid layer cut off after printing. To test the material's performance, remove the solid layer with a knife or razor, then use scissors to cut along the long axis and fold inverting to edge-to-edge using pliers. Observe sharp corners for symmetry and fold along the thread path, gripping and compressing with pliers to fold and release one wall thickness, checking for cracking or delamination. The material should stretch rather than separate; allow it to rest, revealing only visual indications of stretched threads. For more information on 618, visit taulman3d.com.
