ASTM Worldwide’s additive manufacturing applied sciences committee has introduced it’s growing a proposed normal to supply steerage on methods for detecting, quantifying, and classifying contamination inside metallic additive manufacturing powder feedstock.
The proposed normal, WK80171, is being developed by the check strategies subcommittee (F42.01), a part of the F42 AM committee. It’s regarded as related to each metallic powder producers and customers of laser beam powder mattress fusion (LB-PBF) processes.
In a press launch, ASTM mentioned the usual will outline contamination sorts, element strategies for contamination detection and describe how the chosen testing strategy will be carried out to efficiently detect contamination. Take a look at 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 Expertise Heart, commented, “The usual will allow powder producers and additive manufacturing machine customers to 1) establish applicable methods for detecting and quantifying various kinds 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 normal 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 appears to be like to boost high quality assurance, regulatory compliance and course of management and, as ASTM Worldwide’s Martin White & Carl Hauser not too long ago informed TCT, enhance the additive manufacturing provide chain.
