ASTM Worldwide’s additive manufacturing applied sciences committee has introduced it’s growing a proposed customary to supply steerage on strategies for detecting, quantifying, and classifying contamination inside steel additive manufacturing powder feedstock.
The proposed customary, WK80171, is being developed by the take a look at strategies subcommittee (F42.01), a part of the F42 AM committee. It’s considered related to each steel powder producers and customers of laser beam powder mattress fusion (LB-PBF) processes.
In a press launch, ASTM stated the usual will outline contamination sorts, element strategies for contamination detection and describe how the chosen testing strategy could be applied to efficiently detect contamination. Check strategies together with optical microscopy, automated scanning electron microscopy, x-ray computed tomography, and x-ray fluorescent spectroscopy have been examined to assess their suitability.
ASTM member Aneta Chrostek-Mroz, superior analysis engineer on the Manufacturing Know-how Middle, commented, “The usual will allow powder producers and additive manufacturing machine customers to 1) determine applicable strategies for detecting and quantifying several types of contamination; (2) classify these contaminants; and (3) carry out contamination evaluation of each unused and re-used powders.”
Final month, the identical committee introduced the growth of a proposed customary that goals to assist outline the printability vary of cementitious supplies for ‘any given extrusion-based 3D printer.’ At TCT 3Sixty in June, the organisation additionally launched its new producer certification program, which seems to be to boost high quality assurance, regulatory compliance and course of management and, as ASTM Worldwide’s Martin White & Carl Hauser not too long ago instructed TCT, enhance the additive manufacturing provide chain.
