The aftermath is important! - Quality assurance for production
AM products can do more and impress with their efficiency. Ensuring the quality of every component, from Monday to Friday, is of particular importance. We are happy to support you in ensuring quality in production.
Additive manufacturing is becoming increasingly enjoyable. The new machines have the sensors and qualities needed to produce quality day in, day out.
But how do I secure my production? Which workflows offer me the best security?
Whether 3D printing in metals or other materials – after feasibility comes production stability – day in, day out.
We, the Institute of Product Development and Production Technologies, are broadly positioned to solve problems in every step of the process, from quotation to delivery.
Quality assurance is one of the usual concerns here. It should be minimal in terms of effort and prevent unforeseeable costs arising from quality fluctuations in production. We find the practical solution.
For high-strength steel 1.6657, a case-hardening steel, for example, the quality control process using classic parameter development with small cubes is not sufficient. 1.6657 is used in gear wheels. The reason why small cubes are not sufficient for parameter development is that no gear wheel has the shape of a cube. The heat conduction conditions in the actual product differ from those in the ‘cube test’.
How can quality now be assured? Fortunately, new machines for metal 3D printing (SLM, PBF-LB/M), such as the TruPrint 5000 or the IMPACT 4530 LPBF, have built-in sensors such as heat meters (pyrometers) that allow us to verify the quality of the component layer by layer. The temperature is measured at every point of the component during processing and used as a control variable for the quality of the material at every point of the product based on previous quality assurance tests.
There is no more cost-effective and efficient method in this area.
More efficient products and production chains are our strength.
