Physical testing of the 3D printed material is an important step to ensure that it meets the needs of the project and has the desired properties. Here are some common physical test methods used to evaluate the performance of 3D printed materials:

Common physical test methods:
Tensile test:
Tensile testing is performed to assess the strength and ductility of the material. The test sample is usually a standard-shaped tensile specimen, which is stretched by applying force, and the stress-strain curve is recorded to evaluate the elastic modulus, yield strength, fracture strength and other parameters of the material.
Bending test:
The bending test is used to assess the bending strength and toughness of a material. The test sample is bent by applying force between the two fulcrum points, the load and displacement data are recorded, and the bending strength, bending modulus and other parameters are evaluated.
Impact test:
Impact testing is used to assess the impact resistance of a material. The toughness and wear resistance of materials are evaluated by applying impact loads. Common test methods include impact strength test and impact toughness test.
Hardness test:
Hardness testing is used to assess the hardness of a material, including the degree to which the material deforms under pressure. Commonly used hardness test methods include Rockwell hardness test, Brinell hardness test and so on.
Thermal performance test:
Thermal performance tests are used to evaluate the heat resistance and thermal expansion of materials. The commonly used thermal performance test methods include thermogravimetric analysis, thermal expansion coefficient test, thermal conductivity test and so on.
Chemical performance test:
Chemical performance testing is used to evaluate the chemical resistance of a material. The corrosion resistance and chemical stability of the material are assessed by exposing it to different chemicals.
Surface roughness test:
Surface roughness testing is used to evaluate the surface quality and accuracy of the printed part. Surface roughness measurement methods commonly used include surface roughness meter and optical microscope observation.
Test steps:
Sample preparation: Standardized sample preparation according to test requirements.
Test equipment calibration: Ensure that the test equipment is accurately calibrated.
Test: Test according to the corresponding test standards.
Data recording: Record test data, including load, displacement, time, etc.
Data analysis: Performance evaluation and comparison based on test data.
Physical testing of 3D printer filament enables a comprehensive assessment of their performance, helping you select the material that best suits your project needs and ensuring that printed parts meet the required quality standards.
