On the rostrum, Liu Shouzhong, Duan Zhixue, who were the guests of the ribbon-cutting, and Su Wenjie, Wei Caiming, and Zhang Qinghang, who represented Lazy God Technology, cut the red ribbon together, indicating the official establishment of Heqing Creation. Then Wei Caiming returned to the front of the stage, spoke his thickly accented Mandarin, and stumbled over the manuscript: "...... Today, we will spend an hour to show you the 3D printed building created by Heqing, first of all, please take a look at the left front. ”

The crowd had been waiting impatiently, and suddenly brushed it, and all kinds of long guns and short cannons were aimed together in the direction he was pointing, and there was a huge machine covered with red cloth.

"Next, let's take a look at the No. 1 construction 3D printer. Wei Cai said, the red cloth fell, revealing the true face of the No. 1 printer, the so-called No. 1 printer, looks like a gantry tower crane, five meters long and wide guide rail, equipped with a gantry crane-shaped shelf, a huge hemispherical fixed below the shelf, and a huge square box above.

The hemisphere below is the print printhead, and the box contains the printing material.

Chi Jiafeng immediately came to the side of the isolation belt around the gantry crane, and after a burst of wild shooting, the netizens around him also took out their mobile phones and posted everything in front of them on the Internet.

Printer 1 will print a gazebo, designed by architect Wei Ke, using special cement specially customized by AFAB Cement as the printing material. Wei Caiming explained that near the No. 1 printer, Zhang Qinghang and Wang Wanqiang took a deep breath and pressed the start button.

The shelves of the 3D printer began to move along the guide rails, and the huge hemispherical print head hanging below lowered and began to move on the ground, and the netizens and reporters around them shouted: "Hit, start playing!"

"Brother Qian. How is your printhead different from other people's. Chi Jiafeng asked Wang Gandao beside him, and few people noticed that Wang Gan was actually mixed with netizens. Since the trailer of "Free Walking" was released last time, Wang Gan's popularity among netizens has been very high, almost second only to Nan Ming and "Brother Security" Zhao Gaofeng, and he is affectionately called "Uncle Qian" by netizens. However, Chi Jiafeng has a better relationship with him, and usually calls him Brother Qian.

Two days ago, when Su Zhanxihe released the architectural printing technology, Chi Jiafeng paid attention to the fact that the nozzle used by Su Zhanxihe's architectural printer is actually a fist-thick funnel, constantly squeezing the cement out of the funnel, and then stacking it layer by layer according to a fixed path. There is no technical difference with squeezing toothpaste.

But the 3D printer created by Heqing does use this strange huge round printhead.

"This is to improve the printing speed and accuracy, generally speaking, the printing speed and the printing accuracy are inversely proportional, the printing accuracy requires the printhead to be smaller and thinner, and the printing speed requires the larger the printhead, the better, so we adopted a compromise approach, the ball, there are 400 printheads. Divided into 4 different thicknesses, each printhead can be fine-tuned in height and angle. Thus ......"

Before Wang Gan's words were finished, an exclamation sounded all around.

Chi Jiafeng turned his head and burst into a foul mouth: "!"

The print head falls and then moves away, and everyone thinks that they will see a thin layer of printing material on the ground, but anyone who has a little concept of architectural printing. I know that 3D architectural printing is not even practical now, let alone beautiful, it is almost impossible to have any tricks!

All 3D architectural printing, it's stacked cement layer by layer, that's all!

But in fact. What appeared on the ground was a peculiar wall 10 centimeters high.

Looking at the past from the direction of Chi Jiafeng, the first thing I felt was that I saw the waves.

The wall presents a radian in four dimensions, in addition to the beautiful arc of the up, down, left, right, front and back, the whole wall even has a hollow with a gradient of size and shape.

It's a shape that's so complex that it's hard to print on a desktop printer.

Ordinary 3D printing, also known as additive manufacturing, is actually an extension of one dimension from bottom to top, or from top to bottom.

The modeled building is seen as a collection of slices layer by layer, and then printed out layer by layer, which becomes an architecture.

Now, what Lazy God Technology shows is real 3D printing, which regards the building as a whole, synchronously sprays printing materials from all directions to the center, extends synchronously in three dimensions, and even takes into account the one-dimensional interior, printing a complex hollow with a great sense of space and artistic beauty.

On the podium, Wei Caiming continued to read the manuscript and stumbled: " The printing material used in the No. 1 printer is a special concrete jointly developed by Lazy God Technology and Yafei Cement, we call it Keel No. 1, which is sprayed out at high speed from multiple angles by the printer nozzle, and will condense within seconds of encountering air, so as to achieve rapid prototyping, this cement has excellent strength and ultra-fast coagulation speed, with our company's 3D printing technology, in addition to ordinary construction, it can also be used as a core support structure, or used in the rapid repair of damaged buildings......"

Offstage, Qin Yafei grinned, and Lun Zhifeng next to him almost clapped his hands, the stock price is going up!

Keel No. 1, listen to the name!

When Wei Caiming finished reading this paragraph, the exclamation continued to sound.

People who have a concept of architectural 3D printing, or those who watched Su Zhanxi and the press conference some time ago, know that 3D printing is very slow, and the fist-thick nozzle stacks the cement layer by layer, and it takes several hours to print a wall.

But now, by the time this passage was finished, it was only a minute, and the ball hanging under the beam had already turned three times.

The first circle only prints 10 cm, while the second circle has a wider print depth and faster printing speed. After the second turn, there was already a 30-centimeter-high wall on the ground.

This is an abstract wave, the shape of the bottom layer is a small wave, and then now it can be seen that there should be a huge arc above, which is the big wave.

In the third lap, it was already more than half a meter high.

At this time, everyone saw a little more of something, printed out of the wall. Not only is there a hollow, but the hollow also carries more content.

Obviously, the shape of the entire pavilion is hollowed out by waves, but through the hollowing out of each one, a huge and abstract pattern of leaves is arranged on the wall.

This feeling, like the common one on the Internet, uses dozens and hundreds of avatars. Spell out images such as beautiful faces, cute puppies, or round pandas.

But that was modified with software, and now it's typed with a 3D printer.

Five minutes, when the whole pavilion was fully formed, only five minutes passed.

The pavilion, which is three meters high and about three meters in diameter, is presented to everyone like a work of art.

On the front, this is a wave in the shape of a "several". It is very rhythmic, but when viewed from the side, it looks like a branch frozen in a fossil, beautiful and timeless.

In the lower part of the wave in the shape of "several", there is a space for people to stay, and even cement tables and chairs are printed out, and the sun is obliquely shining through the hollow. Spots of light were left on the table, arranged in the shape of new leaves.

Only five minutes. From scratch, a 3-meter-high building appeared out of thin air.

And it's not the so-called "3D printing building" of Su Zhanxi and the kind of stupid big black and rough like a prefabricated board house, printed first and then assembled.

It's a real, 3D printed, unparalleled work of art.

That's the beauty of modern technology. It is the charm of 3D printed architecture.

At this moment, I don't know how many so-called modern avant-garde artists or sculptors cried and fainted in the toilet.

At this moment, the whole square was silent, and everyone was attracted by the gazebo like a master sculpture, and they couldn't move away for a long time.

Through the lens. All this has also spread to all corners of the world, and countless experts in 3D printing have been invited to secret locations to evaluate the technology of Lazy God Technology.

At this time, they opened their mouths wide one by one, and the corners of their mouths were drooling, as if they were demented.

It's a technology they can't even think of.

This technique should be used in the laboratory to print the most sophisticated materials, or to be used as the cover of a nature journal.

However, Lazy God Technology used it to build gazebos?

Just the kind of gazebo where aunts and uncles rest and enjoy the shade?

"Now, please look back. On stage, Wei Cai famously said that no one would laugh at his broken Mandarin with a Qingyang accent anymore.

Everyone almost subconsciously turned backwards together.

Then they saw that at a distance of 30 meters from them, there were pillars about 30 centimeters thick, slowly rising from the steel boxes two meters square, like moso bamboos that had accelerated their growth rate countless times.

No, not moso bamboo, because the pillars are translucent, more like crystal pillars.

These pillars, every two together, grow synchronously. Next to the "crystal pillars", there is a car parked, or rather, the boxes that print out these crystal pillars are actually being dragged by a car.

"The eight machines that you see now are our No. 2 printer, which is a kind of vehicle-mounted printing equipment that is used to make some of the more precise building materials. ”

"This printing equipment mainly uses stereolithography curing technology, the printing material it uses, is also a new material jointly developed by Lazy God Technology and Yafei Cement, it is a viscous translucent liquid at room temperature, after using laser heating and solidification, it will show a translucent colloidal appearance, but please do not doubt that its hardness and toughness are more than ordinary reinforced concrete structures, or simple steel structures. This cement, we call it Liquid Crystal No. 3. ”

At this moment, Lun Zhifeng couldn't help but laugh out loud, now, their stock price is going to rise again!

It turns out that the strange cement they produce is such a tall thing!

Liquid crystal, tsk, it's something that can be sold for a high price! It's taller than the keel No. 1 just now!

Up, up!(To be continued......)

PS: I feel like the terminology is a bit too much, I don't know if I can understand it...... I'll go back and revise it again.

and, 40 reminder votes won...... Theoretically, Uncle Ha is not good at math, who will help me do the math!
