To make copper grates in Minecraft 1.21, you'll need four copper blocks and a crafting table. Place the four copper blocks of the same oxidation stage in the diamond shape and you'll make copper grates. If you want to make a specific number of copper grates you can then use a stonecutter, which also provides 1:1 ratio. These blocks are only building blocks and they are available in four oxidation stages. You can scrape them with an axe or combine them with honeycomb.

Crafter is the Minecraft revolutionary block that introduced auto-crafting to the game. It's fairly expensive as it requires five iron ingots, two crafting tables, two redstone dust and one dropper. It allows you to make both simple and complex items by disabling the cells inside it. The crafter will only work once it received redstone power. So, it's best to connect it to a redstone clock. It shoots out items from the front side only and you can place a chest in front so all items will end up in there.
