Share a story, ask a question, or start a conversation about (almost) anything you desire. Maybe you'll make some friends in the process.
RULES (updated 01/22/25)
- Be respectful: no harassment, hate speech, bigotry, and/or trolling. To be concise, disrespect is defined by escalation.
- Encourage conversation in your OP. This means including heavily implicative subject matter when you can and also engaging in your thread when possible. You won't be punished for trying.
- Avoid controversial topics (politics or societal debates come to mind, though we are not saying not to talk about anything that resembles these). There's a guide in the protocol book offered as a mod model that can be used for that; it's vague until you realize it was made for things like the rule in question. At least four purple answers must apply to a "controversial" message for it to be allowed.
- Keep it clean and SFW: No illegal content or anything gross and inappropriate. A rule of thumb is if a recording of a conversation put on another platform would get someone a COPPA violation response, that exact exchange should be avoided when possible.
- No solicitation such as ads, promotional content, spam, surveys etc. The chart redirected to above applies to spam material as well, which is one of the reasons its wording is vague, as it applies to a few things. Again, a "spammy" message must be applicable to four purple answers before it's allowed.
- Respect privacy as well as truth: Don’t ask for or share any personal information or slander anyone. A rule of thumb is if something is enough info to go by that it "would be a copyright violation if the info was art" as another group put it, or that it alone can be used to narrow someone down to 150 physical humans (Dunbar's Number) or less, it's considered an excess breach of privacy. Slander is defined by intentional utilitarian misguidance at the expense (positive or negative) of a sentient entity. This often links back to or mixes with rule one, which implies, for example, that even something that is true can still amount to what slander is trying to achieve, and that will be looked down upon.

I've been designing and printing 'enameled' pins on my 3d printer for a bit and recently picked up the stuff to actually cast them out of metal. So far I've casted one, and it actually turned out, so I'll probably be making some more this week!
What sort of metal did you use? I have some pins I need duplicated, and have toyed with the idea of doing it myself
I've been using bismuth because of the low melting point (no need for a furnace) . I just picked up some used kitchenware so I could melt it on the stove top.
Pewter apparently has a pretty low melting point too, so that could be an option as well.
Was the picture an open mold that you printed?
The picture is of the 'finished' pin, I'd still like to refine the process a bit.
The general process I follow is:
Hopefully that helps! If you have any other questions I'd be happy to answer them :)
Great description. I'm thinking I'll use some of that expensive castable silicone to make a reusable mold for pewter... or outsource the work to a professional.
It's a hat badge for the marching band I play in.
That's sounds rad! You should post some pics on here if you do end up doing it! Totally understandable if you didn't want the trouble tho!
