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?


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?


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


20-53 µm is working successfully down to layer thickness of 30 µm

Feasibility of production.

Core and contour settings optimization jobs.


- 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 initial window of variables measured for the core.


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.


DED, Directed energy deposition



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.

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.


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
