Sculpteo Performs Elastic Modulus Measurement Tests on 3D Printing Materials

tensile-test-explanationWhilst there is a excellent deal of 3D printing that can be highly artistic and intuitive in nature, there is in addition a significant portion of it that requires and celebrates precision and technical achievement. In order to create a thing to a quite exacting, pre-planned specification, you have to understand to a quite exact degree the nature of the materials with that you are working.

The people at Sculpteo were interested in exploring and documenting information of the elasticity of the raw material that is fed into the 3D printing device. Whilst a few information of this is provided directly by the manufacturers, the team at Sculpteo argues that the data is highly dependent upon that production system is utilized and wanted to set of detailing the nature of a material’s elasticity in a additional exhaustively detailed manner.

Knowing the elasticity of a material is what helps to calculate, during the create phase, against the possibility that any given piece can rupture or break. The many common method for its calculation is the Young’s modulus, in addition understandn as the traction or elastic modulus. Young’s presents data of the amount a material can be deformed in relation to the amount of force required to deform it.

Youngs-modulus-explanationThe team at Sculpteo wanted to conduct tests that may provide information of the elastic behavior, plastic behavior, and rupture points of a variety of materials via the Young’s modulus. Elastic behavior is the initially area reached when force is applied to a material, cavia it to deform but preceding the deformation becomes permanent.

Once the deformation manufactures a permanent alter in the shape of the material, it is exhibiting plastic behavior. Moving past those initially behaviors and continuing to apply excellenter force causes an increase in deformation, major to a rupture in the material.

The test Sculpteo selected to perform was the tensile test, that they explained in a blog post of the experiments:

“A tensile test is an experimental measure, where you try to elongate an object, while measuring the durablity you are via to do so. The elongation system is created with a constant speed, until we reach the breaking point. This gives us equitething we require to draw a force curve based on the elongation. Thanks to those values, we are and so able-bodied to deduce the elasticity modulus of the material, and its elongation at the rupture point.”

Over a period of two days, the tests were repeated at the MSSMat Laboratory and were executed via a variety of materials such as flexible plastic (TPU), white plastic (PA11), and black plastic (PA12), as well as several interventions with the plastic materials such as dyeing or applying smoothing beautifier.

After the tests, the team did not feel sufficiently satisfied to manufacture a statement of the Young’s modulus of the flexible plastic, but did acquire results for the other two materials. The black plastic was discovered to have a excellenter elasticity than the white plastic, and the two applications—dyeing and the application of smoothing beautifier—had no noticeable-bodied effects on the materials’ performance. Let’s discuss this additional over in the Sculpteo Evaluates 3D Printing Materials forum at 3DPB.com.
