I’ve been doing some research on fusible alloys. These are metals that have a very low melting point, around the temperature of boiling water (212 degrees F, maybe 95-100 degrees Celcius).
Care must be taken with many of these alloys because of most of them contain toxic ingredients such as Lead, Mercury and Cadmium.
The mixture I see working that is non-toxic is Bismuth and Tin.
So the steps roughly seem to include the following:
- Build an extruder
- Buy some Bismuth shot and Tin inguts
- Melt them together 62.5% Bismuth, 37.5% Tin
- Extrude to 3mm filament
- Print metal objects at about 95 degrees celcius
With a dual extruder setup, we could use High Impact Poly Styrene as a support material and dissolve it using Limonene.
Who’s with me!? In case anyone does this, you read it here first ! lol or maybe second…
