Companies, institutions like ISO and ASTM define the standards. Companies like Bureau Veritas (BV) , Lloyds Register (LRQA), the American welding society (AWS) or DNV use these standards and build the framework for a specific application.
The certifying agencies are now moving faster in drafting standards more collectively and work towards faster adoption of additive production procedures. Whereas some industries such as Maritime, Oil & Gas and Aerospace have made faster progress, others are catching up thanks to the effort of standardisation institutions working towards more general and modular standards.
The overarching qualification systematic is modular. It means that the procedures can be tailored to the application, built up from a toolbox of different standards they refer to. The goal is to be as comprehensive and at the same time as flexible as possible. Flexibility is necessary, as in the category of DED, the technologies principles are oftentimes very similar while still having unique features or applications that require their specifications.
For any kind of qualification, process traceability and transparency is key. To collect, process and interpret the data in a structured way, the right choice and accuracy of sensors and an advanced logging & control system determines the directness of the qualification process.
To bundle this overwhelming amount of process data, MX3D has developed MetalViz,
A platform, like MetalViz, allows for a centralised overview of the overwhelming amount of process data creating a digital twin of the print. The digital representation can be used for quality assurance, archiving and virtual inspection. The traceability toolkit has been used in various ambitious projects where logging and printing data was a mandatory requirement for the part’s certification.
MetalXL includes a hardware control system for print monitoring and data logging. Thanks to the connected sensors, including current, voltage, and temperature, users can follow the printing process and track parameters in real time in MetalXL Live.
By logging up to 5,000 samples per second on key print parameters creates a 3D print report after the process, allowing visualisation of the logged data at each point of their print in MetalXL Viz.
These print reports give greater insight is to material properties or 3D printed objects by analysing the physical properties and comparing the digital data, faults can be determined earlier and products can have reduced lead times before brought to market.
