Shulker boxes make item duplication much easier because they allow for up to 1,729 items to be cloned at once (including the shulker box). However, there are other ways to duplicate the blocks themselves, though they only work for certain blocks. The best way to duplicate a block is to turn it into an item first, then duplicate the item. On some servers, these techniques are bannable offenses. Note that these techniques are considered 'cheating' by many people and Mojang tries to remove the ability to duplicate in Survival during almost every update. These third-party applications are NOT owned or endorsed by Mojang, so use at your own risk. For Java Edition, this can happen in the Minecraft Launcher, but on Bedrock Edition, you must use third party applications in order to replicate these again. If any of these do get patched, you must either go back versions or use third-party applications in order to replicate them again. It can be treated as an 'everything farm,' since it can 'farm' things that can't normally be farmed, like block of diamonds, dragon eggs and other non-renewable blocks.

This page seeks to teach you how to clone items and blocks without building a separate farm for them, in vanilla Survival mode. When this happens, the contraption will cease to work.
