416 Chapter 406 3D Printer

The arrival of Liu Xuan brought peace to Cheng Yongxing's constantly becoming impetuous heart.

Some time ago, Cheng Yongxing was always uneasy whether he was resting or working.

All kinds of temptations always surround him.The undefended beauties around made his self-control extremely difficult.

People are group animals, Cheng Yongxing always escapes, and isolation from the world is not justified.

This exchange with Liu Xuan at least gave him psychological comfort.

If you can't help it anymore, you can at least take the train to find her.Although this expectation is false and symbolic.But hope and no hope are completely two concepts.

I was anxious some time ago and also feared the unknown.

Two decades of living together may have wiped out all passion, but instead, it is family affection.

If in the world, who is most important to him, Liu Xuan is at least ranked in the top four.As for which of these four people can rank Liu Xuan, that is another world-class problem.

The last piece that had been missing in his heart was made up.Cheng Yongxing can finally concentrate on doing something.

————————

As time passed, Yan Liang, Ye Jing and other assistants had grown up.Like Feng Yan, they can help him stand alone in a certain area.Many of his ideas have executors.

Cheng Yongxing's greatest contribution to the world is mainly some ideas and ideas.

Once he enters the specific implementation stage, his daily work, his contribution value is not much better than that of a serious researcher.

In the daily detail work, Cheng Yongxing found that in most cases, he was disabling help.The main reason here is his reputation.

As long as it is his suggestion, everyone will unconsciously want to follow it, rather than after normal thinking and debate.When everyone confirms that the road is unworkable, a lot of time and resources are wasted.

After several lessons, Cheng Yongxing also took himself out of this daily work.He turned his attention to more valuable jobs, such as 3D printers.

————————

The name of the 3D printer has long been famous in later generations.

Many people even expect that it will lead to Industrialization 4.0, that is, people can produce what they need at home.But it didn't happen, and slowly, the craze passed.

But what most people don't know is that the impact of 3D printers on our lives has not diminished, but it has not happened in front of us.

The most commonly used field of 3D printers is mainly mold and sample manufacturing.It has affected our lives in all aspects.

For example, mobile phones.

3D printers have contributed greatly to the fact that mobile phones can be made so small and compact.

After the popularization of computer-aided (CAD) design, the design of some complicated parts has gradually become possible, but how to process and manufacture these parts has become a difficult task.

Traditional parts design, milling, planing and grinding of tongs are commonly used processing methods. Only these methods can ensure the accuracy requirements of processed parts.

However, many complex parts, especially some parts in mobile phones, will be very complicated due to size limitations.This structure can be designed, but the traditional method cannot be processed at all.Even if it is replaced with a CNC (Numerical Control Machining Center), it cannot be manufactured.

No matter how useful a structure cannot be made, it is meaningless.

With a 3D printer, the situation has changed. The shapes of parts, no matter how strange, can be processed into shapes.

3D printers can do more than that.

The five-axis processing machine tool, which has been so hyped by everyone, wants to solve the problem of special-shaped surface processing.This problem can be solved with a 3D printer!

The samples generated by 3D printing are generally plastic materials.But it is enough to use it as a sample of the mold.Use this sample as a blueprint to make a mold.After the mold is finished, it is transformed into real parts through the casting process.

Of course, 3D printers also have some shortcomings, such as surface roughness and other issues.These are all minor problems, and manual refinement etc. are all available methods.

The second application area of ​​3D printers is the field of equipment manufacturing.

In this field, a large number of parts are produced in small batches.If processed in the traditional way, these special-shaped parts, from concept to product, are at least monthly as a unit. If it involves outsourcing processing, quarter is a common unit.

If it involves continuous modification, the time cost incurred is measured in years.

With 3D printing, it's almost visible is what you get.Not to mention the hour as the unit, the day as the unit, there is absolutely no problem.

Some basic technologies needed for 3D printers are already available in this era.

The first one is materials. Needless to say, engineering plastics are nothing special.

Second, the technologies for motors, print heads, guide rails, etc. are already available.The technical indicators of dot matrix printers are only stronger than 3D printers.

The third is computer computing resources.

The current computer technology is not enough to support real-time calculation, and the model data is converted into coordinate points for 3D printing in real time.

However, pre-calculation can be used to generate the mathematical model as coordinate data in advance.

Use the pre-rendering mode to calculate the print data, and then print based on the coordinate data. This method is similar to a normal dot matrix printer.

Many font files are built into the printer.When printing, use these font files to translate the required content into coordinate points for printing.

3d printing technology.The most difficult thing is its real-time coordinate conversion algorithm.

Cheng Yongxing calculated this part in advance through the pre-rendering mode.As for the error adjustment of the spatial position, the method of continuous correction is adopted.Although it is a bit slower, it can always be achieved.

The rest of the difficulty is nothing.

Cheng Yongxing took a few people, and within two weeks he came up with a simple prototype.

The strength of optoelectronic equipment is not trivial. The three major subsidiaries, nourished by a large number of orders and funds, have grown into giants.All kinds of tools are available. If you want to do something, don't be too simple.

3D printers also need supporting 3D editing software.In order to be lazy, Cheng Yongxing directly used a commercial software 3DStudio.

This is an animation software. Cheng Yongxing used it for a while in the DOS era. It was a bit of an impression. This time he picked it up again.

The use of animation software to do 3D CAD design can be regarded as a first generation.

————————

This printer, as soon as it appeared, was shocked.

Wang Qingshan and others immediately realized its value.

Not to mention anything else, just the development speed of equipment products will immediately have a huge improvement.

3D printers are particularly meaningful to the Optoelectronics Group.Running in small steps is the core idea of ​​the Optoelectronics Department!

For this 3D printer, Cheng Yongxing neither considered applying for a patent, nor did he want to publish a paper.

This kind of technology is patented, and it is estimated that no one cares about it and abides by it.

Various equipment manufacturers will build several for their own use.Even later generations.Some large-scale professional 3D printing equipment manufacturers have very narrow sales areas.

It is impossible to expect it to make a fortune, so why should others know?

After the samples and concepts came out, "Photoelectric Equipment" immediately set up a professional team to conduct in-depth development on it to make it practical as soon as possible.

Several prototypes have been completely protected, as the first level top secret of "Photoelectric Equipment".

Each equipment designer has the right to use, but cannot see the machine.Many people know that the company has a fast modeling machine, but they don't know what it looks like and how it works.

————————

There is no impermeable wall under the world.

In the eyes of the caring people, the secret of optoelectronics is not a secret at all.

Senior sister Li Xiao, on behalf of some customers, bought two 3D printers that have not yet been formed.

No one knows what they use for it.
