In fact, except for the entry-level bungalow, which is 100 euros, all the garden, decoration, furniture, etc. can be earned. For the victims who refuse to pay, of course, they can't enjoy that beauty, and even a family can only live in a 60-square-meter house, and if they are bachelors, they can only live in one room.

1874 was the first year of three-dimensional printing, and it was already architecturally ready to shine, and it was once again dazzling when it came to the display of non-welfare villas. When the people of Guangdong go to the sales center to watch, they will see the three-dimensional printed model of the villa area.

The earliest three-dimensional printing scheme invented by scientists is to use photosensitive resins to superimpose materials layer by layer, and these resins will quickly solidify and harden when exposed to ultraviolet rays, so the printing speed is very fast. However, there is a big problem with this technology, photosensitive materials are not cheap.

This is not a problem for factories to be used for design modeling, but for making these materials into mass production on a large scale. Tangning's hands-on project is to replace photosensitive materials with ordinary printing paper, reducing the cost by 100 times.

Can ordinary printing paper still do 3D printing? Of course. Printing paper is naturally divided into sheets, much like the concept of layering in 3D printing, isn't it three-dimensional to cut the outline of each layer and then glue it together?

Of course, you can't not make no improvements at all, the first thing to do is to increase the permeability of the paper, so that the ink can penetrate the back of the paper, because this is three-dimensional, if it is ordinary ink and paper, they also do extra work to prevent back penetration?

In the past, the rice paper of the Chinese was relatively transparent, which was a process problem. The modern paper industry does not need the paper to be too transparent, and now because of the emergence of three-dimensional printing demand, it has gone back, and the cost is lower.

The position of inkjet printing in the color publishing industry has long been trained in laser printing, because it is liquid, and it can get very realistic colors when mixed, while the toner used in laser printing is solid, and the colors after mixing always look a little different.

Moreover, the inkjet printing printhead can span long distances lightly, which is easy to make the printer very large, and has a great advantage in making large objects. Even though it was much slower than laser printing, Downing still preferred inkjet printing technology to make new printers.

It is a problem to make photosensitive materials in a variety of colors, but printing on paper is not a problem. Inkjet printing has a very mature color technology. The first step is to print out the outline of each layer of the three-dimensional object, and then transfer the paper to the cutter.

The knife used is actually a needle that vibrates at high speed, moving with the contours of each layer, cutting the paper precisely wherever it goes. Due to the complexity of the three-dimensional outline, if you glue it first and then cut it, there is a possibility that the outline cannot be cut.

If you cut it first, it is very difficult to paste, so the cutting needle will leave a very small joint point on the paper, so that the whole paper will still stand up well, in fact, a little effort can be pulled along the contour line. When all the layers are cut and glued, turn on the powerful hair dryer to blow away the scraps that are already crumbling.

Best of all, the scraps can be recycled to make paper, so the cost is lower. Paper is very similar to wood, and when the whole three-dimensional structure is revealed, the texture of this product is like a medium-density piece of wood.

The core of the final quality of the whole product lies in whether the cut edge can be accurately pasted neatly, and the development team has made great efforts in this regard, so it will appear in the last step of the final product is to blow the leftovers.

The whole team was very happy with the results, describing it as "photorealistic 3D objects". However, they also had to solve the problem of print speed. Inkjet, cut, and paste are time-consuming, and it takes up to 24 hours to print a high-fidelity skull.

Boss Tang's patience is not enough 2. 4 minutes, that's not a no. The team racked their brains to make a fuss in all aspects, the slowest of which was inkjet printing. A good printhead can spray dozens of lines at the same time, which still can't meet the speed requirements of Boss Tang, and finally the team installed ten printheads on a printer, and at the same time inkjet, the speed skyrocketed tenfold, and an A4 picture was produced in two seconds.

The team also synchronized the trimming with the dispensing, using two knives to cut and dispense at the same time, so that it could be synchronized with the printing speed, so that the 1,500 layers required to print a skull took only 3,000 seconds. Boss Tang asked, "Can it be faster?" ”

When there is pressure, there is motivation, and finally, an engineer came up with a trick, multiple printers working together, if ten printers are combined, each one does one-tenth of the workload, and then the ten parts are connected, and the speed is increased tenfold, that's 300 seconds. It's been five minutes! Is the boss satisfied? If you can't do it, you can work together with twenty units, 2. 5 minutes.

Well, that's barely qualified. Boss Tang himself uses this super 3D printing working group, and even comes with its own automatic assembly of sub-components. Like the three-dimensional "sand table" he used to study the battlefield on the big table, it only takes ten minutes to print it out with a super working group.

The three-dimensional map of the community in the sales center is a beautiful artwork printed out in 5 minutes, and the people who can buy the house are full of praise, the house has not been sold, but this small model has sold a lot, half a piece of ocean and a model, and there are many people who put it as a plaything at home.

Seeing that this kind of model was so popular, Boss Tang started a map business, making a three-dimensional model of a city's map for one euro, which can sell hundreds of thousands of dollars a month.

With this good thing, you don't have to be afraid to shoot exterior scenes when filming the Three Kingdoms, this scaled-down model is better than the enchantment technique, because you can even light it up when filming, and make some scenes such as burning the company camp for 700 miles, the Battle of Chibi and the like, it doesn't cost much, but the effect is very real.

Downing has already made two video games, one is a fat fish cultivation and the other is a first-person shooter game with enchantment technology, both of which are tightly integrated with reality, and now the people on the interactive entertainment team are looking at the prospect of using model technology.

Now that the city map has been made, it's a good idea to zoom in on the scale and turn the whole city into a playground and drive a race car on the road. The team is making a large-scale game at 1:100. The setting of the game is a 3D printed map of the city.

And the small racing car a few centimeters wide did not have any technical difficulties. The team is going to use the recent Leica phone as a "handle" to control the car in the real city, and the spectators can watch the traffic around the hundreds of square meters of the simulated city, which is really spectacular.

The biggest charm of this kind of racing game is that their cars are real cars, although they are a little smaller, they are also real cars, and the realism of all kinds of crashes and races is off the charts. One of the more interesting aspects of this game is that if the player flips over the car, they have to manipulate the model disaster relief vehicle to turn the car over, which is really fun.

The use of 3D printing in teaching is a big killer, especially in biology. The difference between plane and three-dimensional in human pattern recognition is very large, just looking at the animals and plants described in the book is basically looking at it in vain, whether you know it or not, but when a child looks at the real thing, the impression will be very deep.

The three-dimensional printed model is basically the same as the real thing, because a class of students, or even a school student needs a physical model, so the cost of teaching with this "real thing" is not high, but the effect is doubled.

The same is true in engineering, steam engines, turbines, cable-stayed bridges, when placed on the table to play with, can best stimulate children's enthusiasm and curiosity. Children with a lot of pocket money can also ask the school to print one more for themselves to take home for study, which is not expensive anyway.

Boss Tang wants to donate a paper 3D printer to the primary and secondary schools of all members of the United Nations to improve the education level of the United Nations member states. It is believed that this money will be earned back soon, because a large number of schools in the Allied countries, such as schools with little one computer, and higher education, will buy this equipment to improve their competitiveness. What's more, the digital copyright of each model also costs money, and the consortium and designers also have to charge.

Boss Tang has created a huge industry, the three-dimensional modeling industry. However, can this technique only be used to create models that can only be viewed from a distance and cannot be played with? Boss Tang decided to transform the process a little and try to go from model to practical.

His first practical object was furniture, some small furniture that does not need to be load-bearing, and the strength of the current craftsmanship is sufficient, such as: garbage cans, coffee tables, clothes racks, bedside tables. And some, such as chairs, are far from strong enough to print.

Downing remembered his time in the Canadian forest, when he had nothing on hand but an innumerable amount of firewood, so he could use a small machining center to produce all kinds of furniture, even a wooden house.

In his imagination, it could be that a person needs to print things out when he is away from the crowd, so the materials should be easy to obtain, and the trees would be good. The scheme came out, using wood to reinforce the hollow model. A simple model only needs the wood skeleton to match the hollow of the model.

Complex models, on the other hand, can be filled with a skeleton and wood chips, which are used to fill the gap between the skeleton and the model. With the wooden skeleton, the tables and chairs are much stronger. Although the furniture created in this way is not as perfect as the designer has worked hard to make, it is unique.

Imagine a man in a primeval forest, thousands of kilometers away from the nearest town, what if he wants a piece of furniture? If he had such a printer, he could put wood in and furniture out, it would be too powerful......

This is perfectly possible, because the log can be rolled into thin sheets, like paper, and this kind of furniture rarely uses color, so you can pinch the inkjet part and jump directly to cutting and pasting the thin wood chips, using the same color as IKEA's man-made panels, so you know that it will be strong.

It's really a three-dimensional print, oh no, you need adhesives. After a short period of development, the team really mastered this magic skill of living things, but it also needed a business model.

After some thought, Boss Tang really thought of a way to sell this "inferior product" - to go to the old and young border poor areas to engage in processing business. Of course, where there is a lot of wood, it only takes the size of a small truck to start a furniture factory.

Let the local people produce their own logs and process products for them, and the service is free for families who send their children to school, so this is actually a poverty alleviation service. The wages of the staff and the money for the adhesive are deducted from the incoming materials, and the more they save, they can make more furniture.

Don't look at these processing factories are only as big as small trucks, but the designers are tall, and they can't be sold in Beijing, Shanghai and Guangzhou, and there are still some markets in fourth- and fifth-tier towns
