Ready for pressure equipment

How to produce parts by MetalAM according to the pressure equipment directive ❓ You definitely need a lot of samples and some statistics before 📊 MaterialsMonday

When being certified by TÜV Süd for the production of high-quality metal powder and serial parts isn't enough for providing the best MetalAM solutions for our clients, we need to move on along our vision…

➡️ Next step: Certification of our manufacturing processes and QM system to produce MetalAM parts according to the 🇪🇺 pressure equipment directive 2014/68/EU

Insights into our qualification data set of the samples produced on our SLM Solutions 280 Twin system with 316L:

🔵 1 Qualified metal powder batch
🔵 5 Build jobs
🔵 1 Solution annealing heat treatment process
🔵 72 Tensile strength tests (24 produced in x/y and 48 produced in z)
🔵 72 Charpy notch tests in different build directions and positions of the notch axis

Initial results:

☑️ Tensile strength ↔️ 648.17 ± 6.40 MPa (SD) ↕️ 593.40 ± 8.02 MPa (SD)
☑️ Elongation at break ↔️ 45.19 ± 1.11 % (SD) ↕️ 52.31 ± 1.50 % (SD)
☑️ Verifiable Rm deviation for the positioning within a build job (x,y and z): 6 MPa
☑️ Verifiable Rm deviation between the build jobs with significant changes in layer exposure times: 20 MPa
