3D printers

 A 3D printer works like this, Put just one raw material in it: wood, stone, diamond, iron, even netherite and future materials stronger. Then press on the tool you want(only the tool heads, use a crafting table and the tool head to craft the tool). That makes it use less raw material than crafting it. The printer can't print armors but can print blocks of a material like diamonds and still just use one piece(that means you can print a block of diamond with just one diamond rather than nine by crafting).
