Titanium powders used in powder bed fusion : their relevance to respiratory health

This study aimed to characterise three titanium powders used in powder bed fusion in terms of particle size, shape, and elemental composition for comparison with safety data sheet (SDS) information, and their relevance to additive manufacturing (AM) operators’ respiratory health.

Popis
Shrnutí:This study aimed to characterise three titanium powders used in powder bed fusion in terms of particle size, shape, and elemental composition for comparison with safety data sheet (SDS) information, and their relevance to additive manufacturing (AM) operators’ respiratory health. Thoracic (< 10 μm) and respirable (< 4 μm) particles were present in the virgin and used powders. If inhaled, these particles have the potential to cause adverse health effects. Discrepancies in particle size and elemental composition compared with what was declared in the SDSs were found. The SDSs provided insufficient information, which places AM operators’ health at risk. Recommendations for promoting AM operator health are provided. Hierdie studie se doel was om titaanpoeiers wat tydens poeierlaagsamesmelting gebruik word te karakteriseer volgens partikel grootte, vorm, en materiaal element samestelling vir vergelyking met ’n veiligheidsdatavel (VDV) en die relevansie daarvan op die respiratoriese gesondheid van die additiewe vervaardigingsoperateur. Torakale (< 10 μm) en respireerbare (< 4 μm) partikels was in nuwe en herbruikte poeiers teenwoordig, en indien ingeasem word kan dit tot ongewensde gesond-heidseffekte lei. Teenstrydighede is in die partikel groottes en element samestelling teenoor wat in die VDV’e verklaar word, gevind. VDV’e verskaf nie genoegsame inligting nie, en hou dus ’n gesondheidsrisiko vir die operateur in. Aanbevelings vir die bevordering van die operateur se gesondheid word verskaf.
