Here's an Idea:

I'm wondering if some of the megalithic stones that are located at places like Machu Picchu were perhaps 3D printed instead of being cut-- if the large perfectly-fitted stones were possibly manufactured in place instead of being lifted up the walls, made on the spot without needing to be moved at all.

Fascinated by the mysteries of history, and always curious about humanity's hidden, lost, and otherwise occulted origins, I think I must have heard every possible theory on our forgotten past by now. Still, I've never found a convincing explanation of how the fitting and placing of these megalithic stones was done.

However it was that those oddly precise, organically nested building blocks were so tightly locked together, I've never heard a logical explanation or theory on how it was accomplished.

The Official Story

First, the Incan civilization-- the people who are officially credited with building Machu Picchu-- claimed that they didn't build the original structures, but that the place was already there, built previously by giants.

Ignoring them, archeologists tell us that the Incas, a Bronze Age culture, built it all, using copper tools to cut huge chunks of granite into precisely fitting bricks for their massive temples.

Some Unofficial Versions

Aside from the official 'cut with copper tools' version of the construction of these building blocks, a few alternative suggestions have turned up over the years:

• Poured Stone- A liquid mixture of pulverized granite and some sort of polymer is poured into individual forms to make the bricks.

• Grown Stone- A lost formula for growing stone was employed, using a mixture that expands, like warm dough might rise to fit a bread pan.
  

  

It's possible that the stones could have been made artificially, but neither of the above liquid stone theories can sufficiently explain the precision fitting in some of the stonework at Machu Picchu, even if such techniques as poured stone or grown stone indeed existed at some point in Earth's past.

Imagining Technology to Match Existing Artifacts

Having never been to Machu Picchu, all I have is my imagination and the internet to work with, and I can imagine the possibility that a worldwide, technologically sophisticated civilization existed on this planet not too long ago. While it's a fanciful story that won't fit with our official planetary tale, I can imagine such a worldwide civilization because the evidence is there in countless photographs of ancient megalithic sites, showing technological prowess that most modern builders might only dream of copying.

So, why not? Let's hand ancient Earth some cool toys as a mental experiment, let our ancestors play with technology a bit, to see if these archeological wonders on Earth can be logically explained that way.

Imagine architects of the past, digitally designing a gigantic palace on the top of an old mountain. These architects might have fed the blueprints into a computer, which tells a team of automated granite polymer replicators which brick, how thick, and where to replicate that individual piece of the structure.

For more resistance to earthquakes, the ancient builder's blueprint program could generate random kinks and variations in the shapes of individual stones while retaining the structure's original design.

Our Past is Full of Science Fiction

Layer upon layer, the surface of the Earth shows clues to what has happened before, and some of the most interesting structures in the world are built on top of older structures, places built for things that are never sufficiently explained.

At Machu Picchu, there is evidence that the Incas built their temples on top of existing ruins, but those older ruins seem to defy the history that we are taught.

Reverse-Engineering an Old Stone Wall

After staring at some of those rock walls, trying to imagine how they were fit together so tightly, it's completely natural for the imagination to go into the world of technology, and the best explanation that I could come up with was: a granite powder mixed with polymer as the medium for a 3D printer that spits out the stone according to an artist's whim, or a blueprint, programmed into a robotic building device that hums night and day, perhaps finishing the entire complex in a few days time.

Pre-Incan Earthquake?

At some point in time, a powerful earthquake or some kind of cataclysmic event cause some of the foundational stones at the Machu Picchu complex to separate, and some suggest that such an earthquake would have destroyed the less sophisticated Incan additions. Is this earthquake damage proof that these megalithic structures existed before the Inca started building on top of it with smaller stones?

not quite earthquake proof

These weirdly shaped, tightly fitted stone structures are found in a few other places around the world besides Machu Picchu, and with such large artifacts laying around across the planet, we may someday discover that an advanced technological civilization existed throughout the world, before our history was revised, and the story of this civilization-- possibly our own ancestors and family-- is still methodically being erased from humanity's memory.

We may relearn how to build such artful walls ourselves if we can remember who we are as a species, or if we can uncover our true past through the evidence that is left behind.

That's My New Idea

So I hereby suggest that those peculiarly-shaped stones that fit together with machined precision were 3D printed, right there on the spot, using technology that is still perhaps beyond our current capabilities, possibly employing science that is far more fantastic than I could have imagined so far.
