TriMech uses Stratasys Origin One 3D printers to create production parts for clients. But how accurate are the models created with an Origin One?
Any additive manufacturing (AM) process deployed for the production of functional and end-use production parts must be accurate and repeatable when it comes to the geometric dimensions and material properties of manufactured parts.
One method of evaluating the variability of an additive manufacturing process is to examine the accuracy and precision of part dimensions and mechanical properties, as well as the repeatability of those results on a build-to-build and machine-to-machine basis.
Stratasys Origin One Accuracy Test
The test methodology selected for the Stratasys Origin One Accuracy study examines the variability of an AM process by collecting quantitative measurement data through various mechanical and dimensional tests, and then analyzing the resulting data with statistical techniques.
- For dimensional accuracy, mean and standard deviations (SD) of geometric dimensions are used as a measure of accuracy and precision, respectively.
- For mechanical properties, coefficient of variation (CV) is selected as a measure of variability, since mean and SD values are less meaningful when comparing measurements that significantly differ in base values and units.
The tests were performed across many consecutive builds on separate Origin One systems, and the sample size for the study consisted of more than a hundred manufactured test specimens.
