ASTM E2698 Computed Tomography (CT) for AM Parts
The ASTM E2698 standard provides a robust framework for non-destructive evaluation using computed tomography (CT) to assess the integrity and quality of parts produced through additive manufacturing (AM). CT scanning is particularly valuable in this sector as it allows for detailed internal inspection without damaging the part. This service ensures that AM parts meet stringent quality standards, which are critical for industries relying on high-performance components.
The ASTM E2698 process involves several key steps: specimen preparation, CT scanning, data acquisition, and analysis. Specimen preparation is crucial as it directly impacts the accuracy of the results. The process typically begins with cleaning and positioning the part in a manner that allows for comprehensive coverage during scanning. Once positioned, the part undergoes high-resolution CT scanning to capture detailed cross-sectional images.
Data acquisition involves capturing multiple images at various angles around the specimen. This volumetric data set is then processed using specialized software to generate three-dimensional reconstructions of the internal structure. The resulting images provide a comprehensive view of the internal microstructure and any potential defects such as voids, inclusions, cracks, or porosity.
The analysis phase involves comparing the CT scans against established ASTM E2698 criteria for defect acceptance limits and material properties. This step ensures that parts meet the necessary quality requirements set by industry standards. The service also includes reporting and interpretation of findings to provide actionable insights for quality improvement.
Quality managers, compliance officers, R&D engineers, and procurement professionals benefit greatly from this service as it provides a reliable method for ensuring part integrity and consistency across production batches. By leveraging CT technology, manufacturers can identify potential issues early in the process, reducing rework and improving overall product reliability.
- Specimen Preparation: Ensures accurate data collection.
- Data Acquisition: Captures detailed internal structure images.
- Analysis: Compares results to ASTM E2698 standards for defect limits and material properties.

In summary, ASTM E2698 CT scanning is an indispensable tool in the additive manufacturing sector, providing non-destructive evaluation that enhances part integrity and reliability. This service supports critical applications where precision and repeatability are paramount.
Why It Matters
The significance of ASTM E2698 CT for AM parts cannot be overstated in today’s manufacturing landscape. The demand for lightweight, high-performance components has driven the rapid adoption of additive manufacturing techniques. However, ensuring the quality and reliability of these parts is a complex challenge that requires advanced evaluation methods.
Non-destructive testing (NDT) plays a crucial role in this context by enabling manufacturers to inspect internal structures without compromising part integrity. CT scanning, as specified by ASTM E2698, offers unparalleled capabilities for detecting defects and verifying material properties within AM parts. This capability is especially important given the variability inherent in AM processes.
The standard’s focus on defect detection and acceptance criteria ensures that only high-quality parts are released into production. This not only enhances product reliability but also reduces costly rejections and recalls downstream. For industries such as aerospace, automotive, and medical devices, where safety is paramount, ASTM E2698 CT scanning provides a critical layer of assurance.
Moreover, the service supports continuous improvement efforts by providing detailed insights into production processes. By identifying common defect patterns or areas for optimization, manufacturers can refine their AM techniques to produce consistently high-quality parts. This proactive approach fosters innovation and competitiveness in the sector.
Quality and Reliability Assurance
The ASTM E2698 CT scanning service is integral to maintaining quality and reliability assurance in additive manufacturing processes. The process begins with precise specimen preparation, ensuring that each part is positioned correctly for optimal scanning results. This step involves cleaning the part and aligning it within the CT scanner to avoid misregistration errors.
Data acquisition is a critical phase where multiple images are captured from various angles around the part. The use of high-resolution scanners allows for detailed volumetric data collection, which is essential for accurate defect detection. After scanning, the data undergoes rigorous processing and reconstruction into three-dimensional models. These models enable engineers to visualize internal structures in unprecedented detail.
The analysis phase involves comparing these 3D reconstructions against ASTM E2698 standards. This includes assessing defect sizes, types, and locations according to specified acceptance criteria. The standard defines acceptable limits for various defects such as porosity, cracks, and inclusions, which are critical for ensuring part integrity.
The service also provides comprehensive reporting that outlines findings, including recommendations for corrective actions if necessary. This detailed documentation serves multiple purposes, from supporting compliance with industry standards to guiding process improvements. By adhering to ASTM E2698 criteria, manufacturers can ensure consistent quality across production batches and meet stringent regulatory requirements.
The CT scanning service supports a wide range of applications within the AM sector, including aerospace, automotive, medical device manufacturing, and more. The ability to non-destructively evaluate internal structures ensures that only high-quality parts enter the supply chain, thereby enhancing overall product reliability and safety.
Use Cases and Application Examples
Additive manufacturing (AM) has revolutionized the way products are designed and produced. However, ensuring that AM parts meet stringent quality standards remains a significant challenge. The ASTM E2698 CT scanning service addresses this need by providing non-destructive evaluation of internal structures within AM parts. Here are several use cases where this service is particularly valuable:
- Aerospace Industry: Ensuring that critical components like turbine blades and engine parts meet stringent safety requirements.
- Automotive Sector: Verifying the integrity of complex geometries in lightweight, high-performance components such as exhaust systems or structural reinforcements.
- Medical Devices: Inspecting implantable devices for defects that could compromise patient safety.
- Military Applications: Evaluating parts used in defense equipment to ensure they meet the highest standards of reliability and performance.
- Consumer Electronics: Assessing intricate internal structures within electronic components like heat sinks or structural supports.
In each of these applications, ASTM E2698 CT scanning provides a reliable method for ensuring part integrity. By identifying potential defects early in the manufacturing process, this service helps prevent costly rework and recalls while enhancing overall product reliability.
For example, in the aerospace industry, turbine blades are subjected to extreme conditions that can cause fatigue cracks or other types of damage. Using CT scanning allows engineers to detect these issues before they become critical failures. Similarly, in medical device manufacturing, CT scans help ensure that implants and other components meet rigorous safety standards.
The use of ASTM E2698 CT scanning in AM processes is not limited to specific industries but extends across various sectors where precision and reliability are paramount. This service provides a valuable tool for manufacturers looking to enhance the quality and consistency of their products, thereby improving customer satisfaction and maintaining competitive advantage.
