Tech Fanatic Fell From Sky

Working room.

Lin Han focused on the machine in front of him, surrounded by various large and small parts, as well as several printers, which were dismantled to pieces, with parts everywhere.

In disordered and in a mess, it is him and a machine in front of the desk.

This machine is similar in appearance to a 3D printer with some improvements.

Currently existing 3D printers on the market have material limitations and accuracy cannot meet the requirements.

Lin Han wants to transform a brand new 3D printer to make the machine more perfect in terms of materials and precision.

The 3D printer he is now manufacturing is a military printer from a previous life. The name is a bit long. It is called a high-precision 3D pulse laser printer. The project code is [Wako].

It is mainly used to print some special parts, the strongest function is not limited by the printing material, and the accuracy is sufficient.

The breakthrough of [Wako] back then was created through the addition of supercomputing + artificial intelligence + consciousness after his consciousness became artificial intelligence. It was a technology of high-energy short-pulse laser and micro-material processing. Breakthrough, the basic tool for the subsequent technological development.

【Wako】The whole machine has a total of 3528 parts, which can print 80% of the alloy metal and plastic materials in the manufacturing industry. The remaining high-strength special parts can be forged separately.

3D printing technology is one of the ways to solve the limitation of Divine Weapon's precision parts.

Now that Divine Weapon is restricted by North America and the processing of some precision parts is blocked, Lin Han chooses a multi-material 3D printer to break through this sanction.

The precision 3D printer in front of us only needs to process the material to be printed into a metal wire with a diameter of two millimeters. Under the action of the laser, the material will quickly become a molten state, and then it will be ejected through a needle tube of a special material. , Pouring the model.

The highest precision of the parts manufactured by the printer is 9 microns, which is one-tenth of that of ordinary hair, which meets the production requirements of most parts. With the addition of 2-3 micron ultra-precision CNC machine tools, the basic technology basically meets Lin Han's current research and development needs.

There are production tools and the accuracy meets the requirements. On the basis of this accuracy, he can create basic production tools with higher accuracy. What other technology companies lack is technology. They have researched and developed bottleneck. He does not lack technology here, nor has he developed bottleneck. What they lack is basic development tools and materials.

With the tools and materials available, let him play with it. He can bring Earth into Interstellar Era in less than ten years.

But that is ideal.

In reality, unless he is ready to become enemies with the strongest giants of Earth in a short time, he may die by various means before he develops to that stage.

Moreover, there are many things that he still cannot control.

The disputes between nations cannot be resolved. The humans of Earth are still in the struggle stage between different kinds of Ant Race groups.

Five minutes later.

Lin Han stopped and closed the computer page.

Three mung bean-sized hollow parts, lying quietly, the surface is smooth metal luster, and the internal structure is extremely complicated.

This kind of precision and complex parts requires more than 20 procedures in the traditional "subtractive processing". If any one of the procedures is wrong, the parts will be scrapped and need to be reworked. The yield rate is not high, and there are many procedures. This is one of the reasons why precision parts are expensive.

3D printing belongs to "additive processing". Adding materials requires only modeling and data. Parts can be completed without one minute. The processing time is fast and the yield rate is high. This is a huge advantage. The problem of high cost is also solved here by Lin Han.

However, 3D printing has a shortcoming, which is the insufficient bonding rate between the atoms of the materials, which will cause some special parts whose rigidity, strength and fatigue resistance cannot meet the needs.

So when processing parts, a Catalyst is needed to help improve the bonding rate between the atomic bonds of the material, and Lin Han does not lack the Catalyst formula here.

Precision parts with special strength need to be processed by machine tools after forging.

Lin Han picked up the parts on the printer and combined the three parts into a small steel ball with a smooth surface.

That's it!

Lin Han looks at the small steel ball in his hand.

Perhaps in the eyes of outsiders, this is unremarkable.

If the real technical master understands the technology behind this small steel ball, he will definitely be shocked. This is a metal bead of titanium alloy, and the 3D printer created it.

……

Li Qingyu was immersed in looking at the tender documents, and when Lin Han came in, he handed him the tender documents in his hand.

"You just came, the company headquarters bidding, there has been some progress."

"Simply talk about the proposal." Lin Han took the bid and sat on the sofa next to him. Look down.

"Three thousand acres of headquarters, and some buildings have very high design requirements. The construction time of eight months is too tight. No one dares to pick it up alone for fear of accident. The designer Liang Yi of China Railway behind To propose a plan, he approached China State Construction, Baoli and Gezhouba to join together and said that the headquarters could be divided into four bids. The four companies started construction at the same time, so that there would be a chance to complete the construction within eight months or even six months."

"Sure." Lin Han nodded agreed.

"The construction period is fast, and the construction is difficult. All the plans they jointly give are relatively expensive. If it is a normal schedule, it will be completed within one or two years, and the cost will be 10 billion. But this time, the construction period is too fast. The construction is also difficult. They want 24 billion."

"Promise them." Lin Han said.

Li Qingyu didn't know whether to cry or laugh: "Don't you even think about it? The company only has so little cash now, can you dig out the family property to build the headquarters?"

"Money will come continuously, and later you will find that money is nothing but waste paper." Lin Han's eyes were deep.

"Okay, anyway, the money is yours, you are in charge, I will execute it." Li Qingyu said: "You are so free to come to the company today? Are you in your studio?"

p>

"There is good news."

Lin Han took out a metal bead from his pocket and placed it on Li Qingyu's table.

The beads are rolling on it, and there is no special thing.

Li Qingyu picked up the beads, feeling that the weight was not right, she squeezed it in her hand, and at the next moment, the metal beads were scattered and turned into three hollow parts.

"What is this?" Li Qingyu showed strange eyes.

"Parts."

"What's the use of this?"

"It’s useless, this is a test part. Starting today, North America has The limitation of parts will completely disappear." Lin Han said.

"What do you mean? I found a manufacturer that supplies precision parts?"

"No, we will be a manufacturer in the future." Lin Han chuckled said: "I successfully improved the 3D printer . A 3D printer that can print a variety of materials, with an accuracy of 9 microns."

"Really?" Li Qingyu looked overjoyed.

As the president of Divine Weapon, she is not proficient in technology, but she has seen a lot in various departments and factories of the company. After some technical staff's explanations, she still mastered certain technical concepts.

"Really." Lin Han said: "I have passed the technology to the technology library. From design to technical process, the core is independent technology. Remember to let people apply for patents. At the same time, let the micro-dust equipment production Printers are sold externally, and priority is given to factories that are still cooperating with us, and domestic companies are given priority."

The fine dust equipment is the precision instrument company acquired by Jiang Fengyun. Some special core parts of their company's robots are produced by Dust Precision.

"North American and foreign companies, do not sell parts to us, we will replace them."

"How much is the price?"

"You decide, The cost of the one in my laboratory is 500,000 yuan. You decide the price. There is also a Catalyst and a material stabilizer. The production cost is about 200 yuan per kg."

" Is the cost expensive?" Li Qingyu said in surprise.

"A bottle of wine can buy a house in a small city. In the equipment industry, the more subdivided the field, the more expensive the equipment." Lin Han said.

"In this case, it's four million per unit. Catalyst and stabilizer are priced separately."

"You really know how to do business."

"High-tech products, you know, the company is short of money now, a headquarters costs more than 20 billion, and the bank still owes tens of billions. We are under pressure. And we are investing a lot of'R&D expenses' "

Lin Han gave Li Qingyu a thumbs up.

"By the way, it is announced that the next breakthrough technology is the lithography machine."
