Minecraft – place blocks automatically

minecraft-java-edition

I've seen videos of people making printers in Minecraft – but that requires either preloading unending chains of piston-pushed blocks "as ink" or some way of dispensing them from storage in form of built blocks. I was sure so farm that Dispenser "builds" a buildable block like cobblestone if fed that, but I was sorely disappointed – it drops them as pickable entities. Is the any way to automatically place blocks, without mods, or with some simple mods?

I don't know how exactly these work, but what you may be looking for is Trazlander's magic blocks. The general idea of them is that spawning minecarts spawn in falling sand entities in a certain way with certain IDs, so that when they land, they turn into a certain type of block and make some type of building or device. Then you can make these disappear by turning them into falling sand entities again, and have them fall on half slabs and disappear. Here is a video that explains them (by Trazlander himself):

You will need MCEdit to bring the magic block spawners into the game, but you won't need any mods once you go into the game. Here is where you can find the MCEdit filters for them: http://elemanser.com/filters.html

Trazlander has a tutorial on how to use these as well:
