Feature:Specification:Features:Mechanical Properties Tensile strength (X-Y): 41.89(MPa)10%, Tensile modulus: 490.88(MPa)10%, Elongation at break (X-Y): 21.204(%)10%, Bending strength: 43.435(MPa)10%, Bending modulus: 1104.04(MPa)10%, Charpy impact strength: 279.54 (J/m)10%. Scratch-Resistant Surface Aceaddity rigid resin has good bending strength, hardness, and toughness and its prints can bear accidental drops, and it will not be easy to break during long-distance transportation. It also has a good scratch-resistant surface after 405nm UV-curing. High Impact Resistance Prints that print by Aceaddity rigid resin can withstand high impact and other high-strength mechanical pressure and it will not become brittle over time. That is a good choice to replace of some industrial parts and electronic component housings. Low Shrinkage & High Precision Aceaddity improved the photopolymer resin formulation to reduce volume shrinkage during the curing process, which with high precision will let you have a perfect printing experience and smooth finish print model with aging resistance. Wide Compatibility Aceaddity 3d printer rigid resin is perfectly compatible with most 405nm DLP/LCD 3D printers. Suitable for dentistry, clocks and watches, spectacles, teaching and research, design, handicraft design, industrial parts design, etc. Specification:Model: Ultra Rigid 3D ResinColor: BlackQuality: 1000g/bottleTensile strength: 41.89(MPa)10%Tensile modulus: 490.88(MPa)10%Elongation at break: 21.204(%)10%Bending strength: 43.435(MPa)10%Bending modulus: 1104.04(MPa)10%Charpy impact strength: 279.54(J/m)10%Packing List:1 x Bottle of Ultra Rigid Resin Package List:1 x Bottle of Ultra Rigid Resin
