Nylon Delamination and Pliability Test Object
by Taulman, published
This simple object is used to test for delamination resistance and pliability of 618 nylon material.
A six sided object 50mm wide by 114 mm tall.
The part is printed hollow at worse case settings for delamination testing. One perimeter and one solid layer.
The intent is to insure that stretching of the material occurs before any delamination of thread to thread bonds and that pliability is symmetrical.
Of course the proper temperature is important for bonding on all 3D Printing material and the same holds true for 618. This test was performed on a 2BEIGH3 printer with the following settings:
- Temperature = 240c
- Nozzle = .052
- Layer Height = .26
- Speed = 36mm/s
- Perimeters = 1
- Solid Layers = 1 Cut off after printing
- Print in 618 nylon copolymer
- Remove solid layer with knife/razor
- Use Scissors to cut along the long axis
- Fold "inverting" to edge to edge with pliers.
Observe sharp corners and note as to the inverted bend is symmetrical on all edges.
- Fold along the thread path.
- With pliers, grip and compress to fold and release one wall thickness.
Observe any cracking/delamination. The material should stretch, rather than threads becomeing separated.
- Fold in the opposite direction and use pliers to grip and compress the same spot.
Observe any cracking/delamination. The material should again, stretch rather than threads becoming separated.
- Allow the material to rest. There should only be visual indications of stretched threads and no cracks or delamination.
