3D Matter just hired a new employee and his name is Testman! Testman is a very efficient worker: he appraises geometrical accuracy and visual aesthetics in a single print. His versatility makes him adapted to any material that needs to be assessed, providing us with a consistent test for the years to come. Who is he? Well, he is our new quality testing 3D file!
A key challenge to testing a material’s visual quality is the lack of consistent test that would assess most of the criteria that constitutes what “good” quality is. Texture and details are important if you are printing a small statue, but geometrical accuracy is more important if you are printing a door handle. So in order to provide an overall assessment of material’s quality, there are a number of tests that need to be conducted.
Here at 3D Matter, we had been using the “owl” that we found on Thingiverse as a good first test. We had complemented it with various geometrical tests, and it was working fine for our first few studies. But we were not fully satisfied with our process… so we created our own test and that’s how Testman was born.
Here are some of the key features of our new friend, and what their roles are in the test:
Each part of Testman is designed to test some of the criteria constituting “visual quality”. We gathered these criteria in two main categories: Geometrical accuracy and Details and texture. The following tables sum up which criteria each part corresponds to:
Details and texture
If you see anything missing or if you have suggestions please let us know: we will keep updating Testman if extra tests are required. Also, bear in mind that we only test material-related quality. A lot of existing tests on the market (such as torture tests) are designed to test 3D printers’ quality and are not fully useful for our purpose.
