At A Glance
A study on the Origin Two evaluated 258 parts and nearly 16,000 measurements across multiple printers, materials, and geometries to assess production-level accuracy and repeatability. The results showed that 95% of features were within 50 microns and 99.7% within 100 microns, demonstrating highly consistent performance comparable to injection molding tolerances. Overall, the findings confirm that 3D printing can reliably produce end-use parts at scale, making it a viable option for low- to mid-volume manufacturing.
For years, 3D printing has been a go-to solution for prototyping. It’s fast, flexible, and eliminates the need for expensive tooling. But when it comes to true production, one question has always lingered: Can 3D printing consistently deliver the accuracy and repeatability required for end-use parts?
A recent study on the Origin Two printer set out to answer exactly that — and the results are worth a closer look.
The Test Object
Why Accuracy and Repeatability Matter
When you move from prototyping to production, expectations change. Accuracy refers to how close a single part is to the original CAD design, while repeatability describes how consistent multiple parts are across builds and printers over time. In production environments, repeatability is critical because you’re making hundreds or thousands of parts that all need to meet spec.
How the Study Was Conducted
This study evaluated the Origin Two’s capabilities across three printers, six build heads, two part geometries, and two production-grade materials, Loctite 3955 FST and Loctite 3843 Black.
To simulate real-world production conditions, researchers printed 258 total parts and collected 15,999 individual measurements.
Two part types were evaluated. One was a functional connector designed to represent functional end-use applications, while the second was a test object with a variety of features used to assess accuracy across different geometries.
Each part was carefully measured using high-precision optical and 3D scanning systems, allowing researchers to directly compare the printed parts to the original CAD designs.
The Test Object contains various features to evaluate accuracy and precision across a range of geometries.
The Results: Consistency at Scale
The findings show that the Origin Two platform delivers highly consistent, production-ready results.
95% of all measured features were within 50 microns of their mean, and 99.7% of features were within 100 microns. Across all prints, printers, and build heads, the average variation (3-sigma) measured 0.067 mm.
In simple terms: Parts came out nearly identical, even when produced across different machines and build conditions.
How Does It Compare to Injection Molding?
One of the biggest benchmarks for production is injection molding. The study found that Origin Two’s performance is on par with standard injection molding tolerances. The variability observed in printed parts falls within ranges typically accepted in traditional manufacturing environments.
This is a significant milestone because it shows that 3D printing is no longer limited to prototyping — it can now compete with established production methods.
What This Means For Manufacturers
With this level of precision and repeatability, manufacturers can confidently 3D print end-use parts, reducing their reliance on tooling and long lead times. This makes it easier to scale production, while also enabling faster design validation and iteration. As a result, 3D printing becomes especially valuable for low- to mid-volume production, where traditional manufacturing methods may be too slow or cost-prohibitive.
The data is clear: With the right printer and process, 3D printing can meet real production standards.
