It's got linear rails, so it must be perfect for machining aluminium?

I know your post is a little tongue-in-cheek, but this is probably as useful as the flimsier 3020 toys. Might even have a sensible use for e.g. PCB drilling/routing.
I'd hate to think of the filament costs, and print time. I'd be interested in how long it can operate before the prints delaminate.
It's one of those "I did this because I can" projects.
I thought the video that started automatically after the one you linked to, called "5 Achs fräsen auf der Hobbymaschine leicht gemacht" about a much more substantial machine was way more interesting.

You're admitting to the targetted You-Tube "you might also like..." videos. My autoplay was for a AvE strip-down of a glovebox-sized chain hoist(!)Quote:

Haha, I bet he started printing that at the same time as I started by build log!
I don't mean to be sarcastic about the plastic but that took some time to print!!!!!!!!!!. Scale it up to 8x4 for the 2094 maker fest. It would be fine for a retro fitted pick and place machine but thats about it.
Actually I quite liked that ! Although towards the end I started looking at the one-piece gantry thinking that would make a nice pattern for a cast iron version !
Also, I keep meaning to get around to watching Ave's glovebox-sized chain hoist that YouTube keeps pushing my way.
I have 3D printed patterns for casting using sand moulding. You have to print them 100% fill otherwise the ramming of the sand breaks them (maybe not on the first cast).Quote:

Interesting video, but I only use ABS and that would make a hell of a stink when burning out. I only used to make the patterns and the 'customer' organised the foundrywork (Bronze casting)Quote:

I've been tempted to try green-sand casting of aluminium for years but living in an area where outdoor fires are banned for most of the year I haven't risked it. Maybe when I retire to Tasmania. Which seems to be the mantra for a lot of things these days. I just watch Myfordboy's videos instead.Quote:
