In fact, except for the entry-level small villa that is 100 euros, all gardens, decorations, furniture and other things can make money. For victims who refuse to pay, of course, they cannot enjoy all the beauty. Even a family can only live in a 60-square-meter house on one floor. If they are bachelors, they can only live in one room.

1874 is the first year of three-dimensional printing. There is already an opportunity for it to shine in the building. When displaying those non-welfth villas, it is once again dazzling. When Guangdong people go to the house sales center to watch, they will see the model of the villa area printed out in the three-dimensional manner.

The first three-dimensional printing solution invented by scientists was to use photosensitive resins to superimpose materials layer by layer. These resins will cure and harden quickly when exposed to ultraviolet rays, so the printing speed is very fast. However, this technology has a big problem, photosensitive materials are not cheap.

This is not a problem for factories to use for design and modeling, but it is a problem for making these materials into large-scale mass products. The project that Tangning personally worked on was to replace photosensitive materials with ordinary printing paper, which reduced the cost by 100 times.

Can ordinary printing paper still be used for three-dimensional printing? Of course, the printing paper is naturally divided into pieces, which is very similar to the layering concept in three-dimensional printing. Isn’t it three-dimensional to cut the outlines of each layer and stick it together?

Of course, we cannot make any improvements at all. The first thing we need 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 have done extra work to prevent the back of the penetration?

In the past, Chinese people had relatively thorough rice paper, which was a problem of craftsmanship. Modern paper industry does not need to be too thorough paper. Now, because of the emergence of the demand for three-dimensional printing, the cost is even lower. It is indeed "the veterans are not dead, but they just transfer the battlefield."

Inkjet printing has long been trained in laser printing because it is liquid and can obtain very realistic colors when mixed. The toner used in laser printing is solid. The color after mixing always looks a little bit different from that.

Moreover, the inkjet printing head can easily span long distances, making the printer large, and has great advantages in making large objects. Even if it is much slower than laser printing, Tangning still prefers inkjet printing technology to make new printers.

It is a difficult problem to make photosensitive materials into various colors, and there is no problem in printing on paper. Inkjet printing has mature color technology. The first step is to print out the outline of each layer of a three-dimensional object and then transfer the paper to the cutting machine.

The kind of knife used is actually a high-speed vibrating needle that moves with the contour lines of each layer, and accurately cuts the paper wherever you go. Because the three-dimensional contour is extremely complicated, if you stick it first and then cut it, you may have an indivisible outline.

If you cut it first, it will be very difficult to paste, so the cutting needle will leave a very tiny joint point on the paper, so that the whole sheet will still be well raised. In fact, with a little force, you can pull it apart along the contour line. When all the layers are cut and glued, turn on the powerful hair dryer to blow away the crumbling scraps.

The best thing is that these cut scraps can be recycled for paper reproduction, so the cost is even lower. Paper is very similar to wood. When the entire three-dimensional structure comes out, the texture of this product is like a medium-density wood product.

The ultimate quality core of the entire product lies in whether the cutting edges can be accurately pasted neatly. The development team has put a lot of effort into this, so the final step in the final product is blowing the scraps. After careful adjustment by the team, the alignment effect is amazing, so the simulation of the final product is also amazing.

The entire team was very satisfied with the effect and called it a "photo-level three-dimensional object". However, they also had to solve the problem of printing speed. Inkjet, cutting and pasting were time-consuming, and printing a high-fidelity skull took 24 hours.

Boss Tang's patience was less than 2.4 minutes, which was not possible. The team racked their brains to do things in each link. The slowest one was the inkjet printing process. A good nozzle can eject dozens of lines at the same time, which still did not meet Boss Tang's speed requirements. Finally, the team installed ten nozzles on a printer, and at the same time, the speed increased by ten times, and a picture of the a4 was released in two seconds.

The team also synchronized the cutting edges and dispensing, using double-knife to cut the dispensing simultaneously, so that it can be synchronized with the printing speed. In this way, it only takes 3,000 seconds to print the 1,500 layers of a skull. Boss Tang asked, "Can it be faster?"

There is pressure and motivation. Finally, an engineer came up with a trick. Multiple printers work together. If ten units are combined, each unit will complete one-tenth of the workload, and then connect the ten components and increase the speed ten times. This is 300 seconds. Five minutes! Is the boss satisfied? If it doesn’t work anymore, just twenty units will work together, 2.5 minutes.

Well, this is barely qualified. Boss Tang himself used this super three-dimensional printing workgroup, and even brought it with its own automatic assembly. For example, the three-dimensional "sand table" he used to put it on a large table to study the battlefield, and it only takes more than ten minutes to print it out with the super workgroup.

The three-dimensional pictures of the residential buildings in the sales center are exquisite artworks printed in 5 minutes. People who buy houses praised it all the time. Before the house was sold, many of these small models were sold, half a ocean of each model, and many people were placed as playthings at home.

Seeing that this model is so popular, Boss Tang started a map business, making a city map into a three-dimensional model, one for one euro, and it can sell more than 100,000 yuan per month.

With this good thing, you no longer have to worry about shooting outdoor scenes when shooting Three Kingdoms. This reduced-scale model is better than the barrier technology, because you can even click it when shooting the film, creating scenes like the fire-burning camp for 700 miles and the Battle of Red Cliffs. It doesn't cost much, but the effect is very real.

Tangning has made two video games, one is the first-person shooter with fat fish cultivation and the other is the first-person shooting game with barrier technology. Both are closely integrated with reality. Now the people in the interactive entertainment team are attracted by the prospect of using model technology.

Since the city map has been made, enlarging the scale a little, you can make the entire city into a playground and drive racing on the road. This is a good idea. The team is making a large-scale game of 1:100. The game scene is a three-dimensional printing city map.

The small racing car that is a few centimeters wide does not have any technical difficulties. The team is planning to use the recent Leica phone as a "handle" to control the car to speed up in the real city, and the audience can watch the traffic around hundreds of square meters of simulated cities. This is really spectacular.

The biggest charm of this racing game is that their racing cars are real cars. Although they are a little smaller, they are also real cars. Various collisions and competitions are extremely realistic. What's more, this game is that if the player overturns the car, he has to use the model disaster relief car to turn over the car. The fun is really wonderful.

Three-dimensional printing is a great killer for teaching, especially biology is the most important. In human pattern recognition, the difference between plane and three-dimensional is very big. Just reading the animals and plants described in the book is basically useless. It is not enough to know it or not. However, when a child looks at the real thing, he will be very impressed.

The three-dimensional printed model is basically the same as the real thing. Because students in a class or even students in a school need a real thing model, the cost of using this "physical thing" to teach is not high, but the effect is twice as good.

The same is true in engineering technology. Steam engines, turbines, and cable-stayed bridges are placed on the table to play with them at will, which can best stimulate children's enthusiasm and curiosity. Children with more pocket money can also ask the school to print one more for themselves to take home for research, which is not expensive anyway.

Boss Tang wants to donate a paper three-dimensional printer to all primary and secondary schools of the United Nations to improve the education level of the United Nations member states. I believe that this money will be earned back soon, because the Allies, a large number of schools such as higher education will purchase such equipment to enhance competitiveness. What's more, the digital copyright of each model is also cost-effective, and the consortium and designers also charge fees.

Boss Tang has created another huge industry, a three-dimensional modeling industry. However, is this technology only used to create models that can only be viewed from a distance but not played with? Boss Tang decided to slightly transform the process and try to go from model to practicality.

His first experiment was furniture. Some small furniture that did not require load-bearing was sufficient with the strength of the current technology, such as trash cans, coffee tables, clothes racks, bedside tables. Some, such as seats, are far from printed strength.

Tangning remembered what he did in the Canadian forest. At that time, he had nothing at hand, but there were countless firewood, so he could produce various furniture in small processing centers, and even wooden houses could be made.

In his imagination, it may be that a person needs to print things when he is away from the crowd, so the materials are easy to obtain, so the trees are good. After the plan is out, use wood to reinforce the hollow model. A simple model only needs to match the wood skeleton with the hollow model.

For complex models, you can use skeletons and wood chips, which are used to fill the gaps between the skeletons and the model. With wooden skeletons, tables and chairs are much stronger. Although the furniture made in this way is not as perfect as the designers work hard to make, it is unique.

Imagine a person who is in a primeval forest, thousands of kilometers away from the nearest town, what should he do if he wants a piece of furniture? If he has such a printer that can put wood in it and what comes out is furniture, it would be too powerful...

This is completely feasible because the logs can be rolled into thin sheets, just like paper, and this kind of furniture rarely uses color, so the inkjet section can be pinched and jumped directly to cutting and pasting thin wood slices, and the adhesive is the same as ikea's artificial board, so I know it will be very strong.

This is really a three-dimensional printing that produces all things. Oh, no, it also requires adhesive. After a short period of development, the team has really mastered the magical skills of producing all things, but it still requires a business model.

After some thought, Boss Tang really thought of a way to sell such "low-quality products" to go to old, young, and poor areas to carry out incoming materials processing business. Of course, there must be a place with a lot of wood, and it only takes a small truck to build a furniture manufacturer.

Let local people produce logs and process products for them. Service is free for families who send children to school, so this is actually a poverty alleviation service. The staff’s salary and bonding money are deducted from the incoming materials, and if they save more, they can make more furniture.
