Tensile Testing 3D Printed Products

As additive manufacturing continues to change the manufacturing process with rapid design iterations and cost effective high volume mass-production, the same material characteristics that are important to consider during the design process remain vital to identify for 3D printed parts. Ultimate tensile strength is a test frequently used to aid in selecting a material for application and determining how that material will perform while in use. Continue reading below to learn more about tensile testing for 3D printed parts and the MARK-10 Tensile Tester:

Tensile Testing is a fundamental materials science test in which a sample is subjected to a controlled tension until failure is observed. The process of applying a continuously increasing load to a test sample creates a stress-strain curve until the rupture or break point, showing how the sample reacts throughout the tensile test. Through tensile testing, one can quickly determine how the material will react to forces and ultimate tensile strength can be directly measured. The results from the test can be used to select a material for an application, for quality control and to predict how a material will react under other types of forces.

The MARK-10 ESM750S Tensile Tester is a single-column force tester configurable for tension and compression measurement. For 3D printed products, the tests performed using the MARK-10 are essential for product design and improvement. Physical characteristics must be determined for each material used by a 3D printer for a project, each 3D printer that uses that material, and for each orientation of the print. Designs based off of erroneous material characteristics have a high probability of failure. With the knowledge of how the material performs, designs can be improved leading to safer and more reliable products.


  • Ultimate Tensile Strength – Testing to determine the maximum load carried by the sample specimen
  • Compressive – Process of determining material behavior under a compressive load by compressing the sample specimen and recording deformation versus the applied load
  • Flexural Strength (Modulus of rupture) – Measurement of a sample specimen’s strength before rupture or break
  • Creep – Measuring the deformation or alteration of a sample specimen after the application of mechanical stress
  • Shear – Applying stress to a sample so it undergoes a sliding failure along a plane that is parallel to the forces applied
  • Frictional Coefficient – Determination of the frictional force between two surfaces or objects

Materials Tested: (both 3D printed and conventional parts)

  • Plastics

Recognized as one of the top product reliability labs in the country with a unique balance of testing, consulting and on-site staffing services, Austin Reliability Labs (ARL) is a place where we recognize the hard work and passion that goes into the design and development of your product and want to find any problems in an effort to perfect it. We also understand a reputation is something that builds over time, so we focus on establishing long-term partnerships with each of our clients. With that in mind, we not only specialize in writing and developing all of the tests that we perform, but, unlike other labs, we provide pass / fail reports on all of our tests and decipher the results for you in order to maximize your product’s success. In addition to our on-site staffing and consulting services, ARL’s full array of reliability testing services include: HALT / HASS, Battery Life Tests, Qualification Tests, Environmental Tests, Mechanical Tests, Additive Manufacturing Tests and Custom Tests.

We believe quality is infused by finding every flaw in a product and methodically removing each one until the product shines. As a result, only a thorough, comprehensive reliability test program, as provided by ARL, will allow a product to emerge that will earn or maintain an unsullied and clean brand reputation.
