Tensile Strength: Will It Break Under Tension?
Tensile strength is a material’s resistance to breaking under tension.
A material with a high tensile strength resists breakage under tension, or being pulled apart. Ultimate tensile strength indicates the maximum stress that a material can withstand while being stretched or pulled before breaking. Materials with high tensile strength include carbon, glass, and steel.
Once this maximum stress is reached, brittle materials break very sharply, without plastic deformation, while more ductile materials experience some plastic deformation before fracture.
Today, 3D printing has progressed such that it is able to deliver tensile strength comparable to traditional injection-molded plastics like polypropylene and ABS.
