Physical and mechanical properties basics
The physical and mechanical properties of our products are reported in ranges, or with threshold values with below "<" and above ">" symbols:
- range values reflect the interval of certain property values which are true, and above or below the interval or range it is not
- threshold values with below symbol "<" reflect the level, point, or value below which certain property value is true and above which it is not
- threshold values with above symbol ">" reflect the level, point, or value above which certain property value is true and below which it is not
There are several reasons for using ranges (intervals) and threshold values. The physical and mechanical properties depend on the chosen printing speed, relative viscosity version, color, functional additives, as well as on the printer and printing specifications, such as:
- Effect of printing specifications on biocompatibility and mechanical properties
- Effect of fine tuning on biocompatibility and mechanical properties
- Effect of printers on biocompatibility, safety and mechanical properties
- Key variables affecting mechanical performance of 3D prints
- Tg, HDT, and mechanical properties depend on printing specifications
Tensile Strength is the capacity of a material to resist tension.
Flexural Strength is the capacity of a material to resist deformation under bending moment. It is sometimes called Bending Strength.
Both reflect the capacity of a material in resisting deformation under certain loads. But the loads to which they are resisting are different.
Flexural strength is basically bending strength. The flexural strength of a material is defined as the maximum bending stress that can be applied to that material before it yields or deforms under certail load. It is also called as bending strength or modulus of rupture. For materials that deform significantly but do not break, the load at yield, it is typically measured at 5% deformation/strain of the outer surface. it is reported as the flexural strength or flexural yield strength. In other words, Flexural testing is used to determine the bending properties of a material. Sometimes referred to as a transverse beam test, it involves placing a sample between two points or supports and initiating a load using a third point or with two points which are respectively call 3-Point Bend and 4-Point Bend testing. Maximum stress and strain are calculated on the incremental load applied.
