ISO 14253-2 Dimensional Uncertainty Testing

The ISO 14253 series of standards provides guidelines on dimensional metrology for additive manufacturing and 3D printing. Specifically, ISO 14253-2 focuses on the determination of dimensional uncertainty in additive manufacturing processes. This service is crucial for ensuring that parts produced by AM technologies meet the required specifications with high precision.

The process involves a series of measurements and calculations aimed at quantifying the uncertainties associated with the final dimensions of 3D-printed components. These uncertainties can arise from various sources, including layer thickness, build orientation, and post-processing steps. Understanding these uncertainties is essential for quality control and compliance with industry standards.

Our laboratory uses advanced metrology equipment to perform these tests. The testing process typically involves several key steps:

Preparation of Test Specimens: We create specimens that are designed to represent the typical geometry and material properties used in your additive manufacturing processes.
Metrology Setup: Using precision measurement instruments, we set up our testing environment to ensure accurate measurements. This includes calibrating our equipment according to ISO standards.
Data Collection: High-precision measurements are taken at multiple points on the specimen using coordinate measuring machines (CMMs) and laser scanning systems.
Uncertainty Analysis: After data collection, we analyze the results to determine the dimensional uncertainty. This involves statistical methods to account for various sources of error.

The final step is reporting the findings in a comprehensive manner that includes all relevant parameters and uncertainties. This report can then be used by your team to improve processes or meet regulatory requirements.

Understanding dimensional uncertainty is particularly important in sectors such as aerospace, automotive, and medical devices where precision is paramount. By partnering with us for ISO 14253-2 testing, you ensure that your additive manufacturing processes are optimized for quality and reliability.
