5. SIRRIS / background.
● Since a couple of years Höganäs see more and more demands for
powder to be used in Additive Manufacturing.
● Markets not fully defined
● Technical requirements from customers are unclear. Particle size ?
Trace elements?
● Are our powders performing correctly in the common processes?
● Need to verify but how?
Olof ANDERSSON | Höganäs Belgium SA5 |

6. SIRRIS
Reality check with SIRRIS.
Will our powder perform in the common processes?
● SLM and DED
● 316L and IN 625 - > 4 different powders.
● Powder behaviours in the printers? Flow, particle size and shape.
● Mechanical properties in build components?

7. Confirmed flowability trials with 20-53 µm on a
commercial SLM equipment.
● Flowability main tank to recoater - OK
● Flowability recoater to chamber - OK
● Spreading aspect on base plate - OK
Olof ANDERSSON | Höganäs Belgium SA7 |
20-53 µm is working successfully down to layer thickness of 30 µm

8. Feasibility of production.
Core and contour settings optimization jobs.
Olof ANDERSSON | Höganäs Belgium SA8 |
- Support settings
- Core settings
- Contour settings
Several optimization jobs are carried out, producing a
matrix of cubes of each material. They will be afterwards
visually inspected and a density analysis will be
performed.

the core.

10. Conclusion of SLM evaluation.
● The powder flowability was revealed good.
● Höganäs powder 20-53um SS 316L allowed to produce dense parts.
● The tensile samples show values expected values for the SLM
technology.

Front (left) and back (right) faces of 316L sample.
Laser Power 930 W, Speed 300 mm/min, powder flow 3,8 g/min, average layer thickness 375 μm.

13. Conclusion from DED
● The Powders tested was suitable to have a well-shaped
powder flow out of the nozzle.
● High dense parts ( > 99.3 % pores) were obtained.
● Tensile results shows mechanical values in the same range
than expected in the literature for YTS, UTS for DED
samples.
Olof ANDERSSON | Höganäs Belgium SA13 |

14. Final Conclusion
● Based on SIRRIS report we felt secure to go to the market
with our powders.
● Market plan
● Launched marketing and sales support activities.
● The report is beneficial tool to enter
materials lab and R/D centres.
● Commercial successes in
Europe and USA
