Quality Assurance & Control

Making Your Parts to Your Specifications

The seamless integration of our Manufacturing Partner Network, the in-house applications engineering team, and the Xometry Quality Assurance Lab enables us to back every part we ship with the Xometry Quality Assurance. Our professionally-trained quality engineering team continuously improves the quality control process to bring you part quality peace of mind on every single order. We have in-house Quality Control labs located in Germany, the UK, Turkey and China.

We work with both custom and general tolerances: ISO 2768 (fine, medium) and ISO 286 (Grades 8, 7, 6) for CNC machining and sheet metal fabrication, DIN 16742 and ISO 8062 for formative manufacturing technologies, and ensure standard industrial tolerances for 3D printing.

Xometry is ISO 9001:2015 compliant. Our diverse manufacturing suppliers also have the certifications you may require in various industries (environmental management, automotive, medical, aerospace).

• ISO 9001
• ISO 14001
• ISO / TS 16949
• ISO 13485
• AS 9100
• Other quality certifications available upon request

Equipment Used for Quality Control

Xometry and the facilities in our Manufacturing Supplier Network have the latest equipment to perform inspections your way:

• In-line CAD stations for our technicians
• Part drawing creation to your datum schemes
• Measuring equipment certification programs
• Coordinate measurement machine (CMM) from Hexagon Metrology (Browne and Sharpe), Zeiss, Nikon, and Mitutoyo
• Shadowgraph devices
• Mass spectrometer (XRF) to validate material compositions
• Ring and thread gauges
• Gage blocks and gage pins
• Assortment of micrometres and callipers

Inspection Services Offered by Xometry

Inspection services play a vital role in ensuring quality control and compliance with standards in various industries. If required, Xometry and its manufacturing network can provide customers with the following quality control certifications:

• Standard Measurement Protocol: This protocol ensures consistency and accuracy in measurements, reducing errors and variations. It involves using calibrated measurement tools and following specific guidelines to verify dimensional accuracy, tolerances, and other relevant specifications.
• First Article Inspection Report (FAIR): It is typically required for the initial production run of a new product or component. It involves a comprehensive examination and measurement of a representative sample from the first production batch. The FAIR verifies that the product meets all specified requirements, including design specifications, engineering drawings, and contractual obligations.
• CMM Report: CMM stands for Coordinate Measuring Machine, which is a highly precise measurement system used to inspect the geometric characteristics of objects. A CMM Report provides detailed information on the measurements obtained using this machine, such as data on dimensional accuracy, form, orientation, and position of features.

To ensure that our orders meet Xometry standards, we closely monitor the performance of our suppliers and can furnish certifications and reports as needed. The following quality documents are available for all our manufacturing technologies (CNC machining, sheet metal fabrication, 3D printing and injection moulding).

• CMM Inspection Report
• Material Certificate (for metals only)
• Standard Measurement Protocol
• First Article Inspection Report (FAIR)
• RoHS (Restriction of Hasardous Substances Directive)
• REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals)
• Certificate of Conformance
