I have a "gentleman's" foundry lol, I thought to call it that because its in the basement so compared to the guys with roaring big oil and gas fired furnaces in the backyard its rather diminutive, prim and proper. (I have riged ventilation as some melts can omit same nasties) Everything is investment cast using either wax, 3D resin or 3D filament patterns, nothing much bigger than your fist. The set up is a 3kg electric melter, burn out oven and a vacuum caster. I've cast AL, silver and bronze.

Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

In case anyone is interested in the mixing of 3D print technologies with green sand core based casting here is what I'm trying to make:
I thought it would be interesting to make T-Slot cores so I 3D printed the core box.
Now the core mixture gets packed into this and then the core box is split and the compressed part laid on a metal plate destined for baking in the oven.
One baked. Three yet to hit the oven. To avoid having to drill a hole and since the pattern (unfinished here) has a hole in the center I need a core for it too.
I still had the core box from the Gingery Lathe TailStock:
So I made a short core and baked that too. The cast aluminum core holder was to help keep the core round in the oven.
I've yet to put glossy paint on the pattern and although the primed version pulled nicely from sand I think I have possibly made the draft backwards on the cores.

Ditto.
Take my pattern for making levelling feet. I can make 4 of them in an hour that need 5 mines of cleanup. Minimum swarf. Plus, you can easily cast a rough version of something that would be timely in cnc
