Finer powders around 15-25 \u03bcm provide the best resolution.<\/p>\n\n\n\n<p><strong>Q: What safety precautions should be used with metal powders?<\/strong><\/p>\n\n\n\n<p>A: Conductive containers grounded to dissipate static charges. Argon or nitrogen atmosphere glove boxes. Dust explosion prevention systems. PPE.<\/p>\n\n\n\n<p><strong>Q: Does metal powder go bad or expire?<\/strong><\/p>\n\n\n\n<p>A: If stored properly in sealed containers, metal powder can last 1-5 years depending on the alloy. Moisture control is critical.<\/p>\n\n\n\n<p><strong>Q: What is the typical purity level of metal powders for AM?<\/strong><\/p>\n\n\n\n<p>A: 98-99% purity is typical for gas atomized AM powders. Higher purity reduces contaminants and improves final properties.<\/p>\n\n\n\n<p><strong>Q: Which alloys are compatible with biomedical implants?<\/strong><\/p>\n\n\n\n<p>A: Titanium and cobalt chrome are commonly used thanks to biocompatibility and ability to post-process to final implant requirements.<\/p>\n\n\n\n<p><strong>Q: What metal AM printing methods use powders?<\/strong><\/p>\n\n\n\n<p>A: Main methods are binder jetting, powder bed fusion via laser or electron beam, and directed energy deposition.<\/p>\n\n\n\n<p><strong>Q: How expensive are metal powders compared to bulk metals?<\/strong><\/p>\n\n\n\n<p>A: On a per-kilogram basis, metal powders are 10X to 100X more expensive than bulk forms depending on alloy and process.<\/p>\n\n\n\n<p><strong>Q: Can you print pure metals like silver and gold?<\/strong><\/p>\n\n\n\n<p>A: Yes, but alloyed versions are more common for better strength and printability.
