a
PI = photoinitiator. The photoinitiator used was Irgacure 2959.
b
To achieve 3D printing of the 95/5 dog bone pieces, 20 wt % PI was necessary for satisfactory printability. For the 3D printing of the 95/5 rings, 5 wt % PI was used.
c
To achieve 3D printing of the 100/0 dog bone pieces, 20 wt % PI was necessary for satisfactory printability. For the 3D printing of the 100/0 rings, 5 wt % PI was used.
