3D Printing metal casting flasks (Modular flasks PART4) pattern changes & Second greensand casting

Modular Flasks (PART4). So a few changes have been made to the 3D printed modular flask designs, i a huge fan of making quick updates and 3d printing them, so I 3d print the the new design and turn them into aluminium! (just like magic) lol i wish, actually I make two test castings in aluminium using the greensand technique and use the home 3d Printed clip-together modular flask patterns to make the mould. The results are surprising... I'm hoping this project will amuse the DIY "metal casting at home" crowd. Particularly those home casters with 3d printers. i'm hoping eventually to have a lovely 100% reusable metal casting flask pattern that anyone can 3D print and assemble at home, then with it they can go to the shed and fire up the old foundry burner and then cast themselves a set of modular flask sides to assemble later into a fully complete metal casting flask! Not a small challenge... i started this wanting a metal flask and now i'm into it for completely different reasons, i'm enjoying the conversation we're having so much , and i'm loving the way the questions, tips and comments are shaping the way it's all going. I'm loving how you guys are pushing me to think in completely different ways! So unlike a more conventional flask that has mainly straight and flat sides (and is usually cast in one go), this one is all about flexibility, i want someone to be able to cast any size flask with the same modular flask patterns and having the flask patterns modular is key to this. It might not work out but my 'dream' would be to be able to cast any size anytime with a minimum of fuss once you have some flask modules 3D printed! There is still no guarantee that this whole, design then 3d Printing then casting in aluminium process, will end up with a metal flask that is any good... We'll have to wait and see! that's the exciting part, working it out and trying stuff out, using the old noodle and coming up with changes based on the previous castings or amazing ideas that you guys have come up with! If it doesn't work out i'll just make a normal flat sided flask and show you that instead, but while the iron is hot i'm striking as hard as i can! I just want to make my own homemade aluminium casting flask bejeezus! I'm casting in aluminium (LM25) and it's lovely stuff. I'm going to have to use my biggest crucible soon!

I'm not sure where yet but probably on https://www.thingiverse.com/JulianHG/designs So you will be able to modify, copy, alter or do anything with them :) PLEASE SHARE IF YOU CAN! - it makes a huge difference! thank you! #ModularFlasks #CastingMetalFlasks #CastingFlask
