Wow, outstanding video! I wish more TH-camrs did deep-dive project videos like this. The STL files you shared really make this S-tier content. I was planning to get my wife a nice large brayer, then saw how much the nice ones actually cost (if they’re even in stock) I’ve purchased most of the supplies, and am really excited to make an awesome gift!
I love the use of 3d printing the inner core and mold base for casting! Great innovation! I don't know if you know me, but I developed this brayer/roller casting process in 2017-18ish. It's exciting for me to see so many people making rollers now! If you're interested, I'd be happy to share some notes and variations I've been working on? Cheers! Ross M.
short answer: yes. BUT two problems come up. Firstly, the thicker rubber makes it harder for air bubbles to evacuate the mold, you might end up with microholes in the surface of your rubber if you try to pour multiple brayers from the same batch or make a brayer larger than 5 inches. You need a vacuum chamber to degas your rubber if you want to push beyond this limit. Secondly, 50 durometer rubber is very hard and not as flexible and forgiving as 30 durometer. If the inside of your mold is not perfectly round (like PVC pipe) then you will have an uneven printing surface. The acrylic tubes I get off amazon sometimes have varying quality but are generally close enough that I think it works. Best of luck!
Excellent!! Thanks for this brilliant process and tools. You rock!!

Thanks for making us smile, too! It helps.
this is awesome! This is the kind of thing that makes me happy that I bought a 3d printer. Thanks for this!

Of course I know you Ross, I saw your demo at MAPC 2022. I'll reach out to you on instagram.
Tanks!!! Does Smooth-On ReoFlex 50 works? That Is what I can find at my hometown
