Episode 48 — Layered Futures

I was sinking deep into my Throne of Sloth, staring at the 3D model of a roundabout on the living room’s 4K monitor, which I’d mirrored from my PC.

"...Yeah, explaining this with just 2D drawings is going to be a massive pain."

Garam, the man running the site, was a stubborn craftsman. If I tried to lecture a man who carves stone about "circular rationality" using nothing but lines on a piece of paper, it would take forever to convince him.

(As a Project Manager, I need an intuitive "final vision"... a mock-up. And it has to be something physical they can actually touch.)

I checked the time. Bartos wasn't due until tomorrow morning. I still had plenty of time.

I smirked and picked up my phone.

"I’ve got points to burn. ...Lumina Shopping (Japan Version), search: '3D Printer, Industrial, Full-Color Multi-Material Model.'"

The screen displayed a lineup of cutting-edge fabrication machines that would have been completely out of reach back in Japan. I picked the flagship model, equipped with an automatic material exchange system and full-color support.

Purchase Complete: Industrial Multi-Color 3D Printer 'LUMINA-CRAFT S5 Multi-Chroma' — 2,500,000L

—Ding-dong.

As usual, the delivery was explosive. I reluctantly stood up from my Throne and hauled the massive box from the entryway into my study.

Upon opening it, I found the main unit with its robust chamber structure, topped with an "Auto-Material Station" capable of managing sixteen different filaments simultaneously.

(...Beautiful. This mechanical intimidation factor is irresistible.)

I immediately installed the dedicated slicer software on my PC and connected the printer.

The specs of the S5 Multi-Chroma were on another level.

While maintaining a maximum print speed of 600mm/s, the purge (cleaning) speed during material swaps was optimized to the extreme.

Furthermore, an integrated AI camera monitored the surface of the build in real-time, automatically detecting and correcting color bleeding or layering errors. It eliminated the need for a human to hover over it—it was truly "pro-spec for the lazy."

"Alright, assigning colors to each part... and start slicing."

On my PC, I set the roundabout's road to "Asphalt Grey," the central island to "Grass Green," and the sidewalk to "Stone Beige." I also funneled "Warning Red" and "Regulatory Blue" into the road signs.

The layer pitch was a high-precision 0.08mm. I didn’t forget to set the purge tower required for multi-color printing.

"Start print."

—Whirrrrr...!

The internal silent fans roared to life, and multiple filaments began shuttling back and forth through the tubes.

Beyond the acrylic window, the head moved with magical speed, painting different colors and stacking "fragments of a living city" out of thin air.

Occasionally, the mechanical clicking of the filament switching set a pleasant rhythm.

"...I could watch this all day."

At some point, Tama had wandered into the study and was watching the vibrant layers stack up with a look of curiosity.

Meow. (...You bought another toy, didn't you?)

"...Look at this, Tama. This is 'Sculpture of the Future.' I bought it so I could explain things to everyone."

Mrrp. (You just wanted to buy it yourself...)

A few hours later.

The printer’s completion chime rang, and the build plate slowly descended.

Sitting there were the circular intersection reproduced in perfect color, vibrant miniature road signs, and samples of "flags" with a sharp contrast of red and white.

I carefully removed the model and began snapping off the minimal support structures.

"...Perfect. This should shut Garam up."

Spread across the table was the full-color roundabout.

The green of the grass, the grey of the road, and the vivid red of the signs.

It wasn't just a model; it had the power to demonstrate the "new rules" to be installed in this city in a way that was obvious to anyone’s eyes.

I carried the finished model to the living room table and prepared the materials for tomorrow’s presentation.

(Alright, prep complete. ...Ugh, looks like I’ll have to do a lot of talking tomorrow. Better get some sleep while I can.)

I powered down the PC and returned to my Throne of Sloth.

In the darkened living room, the newly finished miniatures bathed in the moonlight, casting shadows that looked like a real city.

"...Tama. Tomorrow, we’re going to use these to blow their minds."

I pulled Tama close and, along with a pleasant sense of fatigue, fell into a deep sleep.
