Hourglass method thanks for that awesome suggestion, i'm seriously considering it. In your method, we'd have to ensure the raw metal chunks are...
Thx! Of the low-temp metals they list, only these seem to be low-toxicity: gallium, tin, zinc, bismuth. Of those, gallium's temp seems too low...
i get that this website is dedicated to traditional casting, not PM. So, i won't post about PM if that offends anyone. @Kelly, i share your...
hi Kelly et al i am totally grateful for your feedback. And i have much respect for folks who have deep experience with foundries and metals. I...
Which aspect of sintering do you consider unsafe?

i'm wondering if a flux or lubricant can prevent that.
i've no intention to go into production until the process is well-tested and validated, if that's what you mean. can you plz link to that? I'm...
Plz tell me more! What is the difference? What would result if we melt? Pethaps we can mitigate this issue with a very very slow, lower temp...
Simple is exactly what I'm trying to do :) Yes, this is small scale production of a product. But, not for-profit. We are a nonprofit mentoring...
hi, thx for reply. I'm making a little bracket, which will be bolted down with a nut and bolt, with a hand-wrench. Tightening the nut, and the...
hi I need a low-toxicity, low-melting point metal (before casting), to cast hardware parts. The cast object will be approx 4" x 1/2" x 1/4"....
