Second video on perfecting the art of casting and 4th video on this adventure. This is all in the quest to make my own performance cylinder head for my race bike.
I'm an engineer and do a lot of 3d printing, ultimately you will struggle to ever print as flawless as you like with any form of 3d printing straight off the printer so you have to decide on where your tolerances are important. for the cylinders and such you'll probably have to ream them out, but if you can get all the important mechanical surfaces nicely finished with post processing then there's no issue with the outside structure etc on being visibly 3d printed, in fact it adds to the origins of where its come from! I love the tower as a solution to the spills haha but an easier way might be to dig your mould deeper into the sand and dig a wider "funnel" shape to make it easier to pour into. If it leaves a big weird sprue/ base you can just chop it off. This is so cool man good luck!
First you have to mix the white mixture reaally good Then you have to vacuum it Then you have to pour it in the mold And vibrate it really good And again vacuum it and then let it sit I’ve seen people do this method and have a casting so clean that even the 3d printer lines were visible in the casting
Yes I believe it will be big enough but it will be close, the furnace kiln will be fine, it's only the crucible size that I think will be close to the limit.
If you don’t like to spend allot of money on a vacuum pump Just get a fridge’s compressor and run it There will be a side sucking air and another blowing Use the sucking side (the compressor is round and most likely black) Or u can just use a normal air compressor
No I haven't tried that, It did cross my mind but I'm sure they aren't water tight as I'm printing with 0% infill and 2 wall thickness, have done a couple castings since with no issues like that. 🤞

Ok, thanks for the info.
Such a cool project, keep up the good work!
Thanks Noah , will do!

I did two of those steps just didn't have a vacuum chamber.
Building one as we speak.
Loving the progress so far, getting better with every attempt. When you get to the full size version, will your equipment be big enough?

Getting closer 🔥
Hopefully just one more 50% then on to full size!

Did you check if your 3d prints are water thight? Wouldnt it cause problems in the mold if it wasnt?

@@TheMotorcycleForge Ok great. If you do want to make them water tight, spray paint enough clear coat on them. That should make it water tight.
It would defiantly make the outside water tight, only issue would be the water jacket inside the head. @@Woodzey
