3D printed natural structural planes.

No.	Specimen	Specimen material and target test	Test type	Specimen preparation	Sources
1		Polylactic acid		Scanning of natural rock mass structural plane using 3D scanning technology	[89]
		Shear tests		The information on the structural plane of the natural rock mass was printed and used as a mold, and the repetitive pouring of the structural plane was achieved on this basis
2		Acrylic resin		Acrylic resin was used to prepare the structural plane, and shear tests were carried out	[90]
		Shear tests
3		Polylactic acid		3DP method was used to make the shear sample mold, and then, the sample was poured	[91]
