The International Organization for Standardization (ISO) has published ISO 5425:2023, the first standard for PLA filament in the context of 3D printing. The standard defines technical specifications and guidelines for the use of PLA filament.
According to ISO, the standard ensures that PLA filament is used consistently and in a quality-controlled manner. It includes basic parameters such as appearance, weight, diameter and ovality tolerance, as well as specifications for packaging, storage and transport.
The foundation for the standard was laid back in 2019 with a proposal from Chinese company Esun and Beijing University of Technology and Business. Subsequently, a group of experts worked out the details.
After ISO, the standard went through several rounds of voting and a public consultation process. Since there were no technical objections, the final steps could be skipped.
Details can be found directly at ISO.
