Super cool projects! Welcome from near Ottawa. Love to see some pics of your patterns and any coreboxes etc.
My two 3D printers have each earned their keep by pooping out usable foundry patterns, but I don't like to admit it.
As a molder, wooden patterns are so much nicer to work with!
It takes time to find good deals on all the used woodworking machines one "needs" though, and even then you still have to make room for them and learn how to get good at using them. That also takes time. Meanwhile a printer can mostly cover the same bases, and almost as well.
At the cost of about half my sanity, trying to get draft and fillets to work, etc., these infernal machines have somehow earned their place.
