About the program

What is harz labs
test program?

Before our resins enter the main product line, they go through the stage of open (beta) testing. This program allows you to become a tester and help us improve the properties of the resins based on your feedback. There are open and closed test resins. The resins from open test can be purchased directly from our website (products - test materials). However, the resins from closed test can only be obtained after filling out a form (at the end of the article) and further discussion with a manager.

Test materials are in the developing stage, so they may be imperfect and subject to change until they are finished.

Who can become a tester?

A 3D printing specialist or company can participate in the program if they use photopolymer 3D printing in their professional work and have validated devices for post-processing. Additionally, they need to have competencies aligned with the intended use of the material they want to test.


Testers receive non-commercial access to our newest samples.

How much it costs?

It's absolutely free.

Is there a reward?

No, this program is voluntary.

Where to send a feedback?
