Chen Xin installed these powerful things on the land aircraft carrier, and the captain naturally had to report to his superiors.


    How can the high-level people not pay attention to such an adverse thing as 3D printing equipment after getting the news?


    "The 3D printing equipment is not as powerful as you think. It is mainly used for emergency preparation in the European battlefield." facing the representatives sent by the senior management and the military to ask about it, Chen Xin didn''t bother to explain. He took them to a 3D printing equipment he redone and showed them.


    "Now I use this machine to print a set of power armor. In addition, I have a set of power armor I asked someone to take from the factory. You can compare the difference between the two." Chen Xin said, and started the equipment to make it work and print the power armor.


    Because the internal space of this equipment is very large, a large number of parts can be printed together during printing, so the printing speed is very fast.


    But the representative from the top saw some clues, but he didn''t mention it here. He just silently watched the whole power armor printed in the form of parts.


    The parts were printed out and the workers called by Chen Xin quickly began to assemble.


    Originally, in terms of the design of the whole set of equipment, it was automatically assembled by the supporting mechanical arm and production line, but now it is just a display, so Chen Xin asked the workers to assemble it.


    A power armor has complex structure and many parts. It is not easy to assemble it. If there is only one person, it will take a lot of time.


    However, Chen Xin obviously couldn''t let the military and senior people wait so long, so Chen Xin called a group of skilled workers, who also brought various auxiliary tools, so it took only about two or three hours to assemble the whole set of power armor.


    As like as two peas of 3D printed power armor were completed, another set of power armour was prepared to be pushed forward. The two seemingly identical power armoured units were placed before the military and high-level representatives.


    "How long does it take you to assemble a set of power armor?" having roughly understood what Chen Xin wanted to express, he took the initiative to ask the workers aside.


    Without much thought, the workers quickly replied, "if we are on the production line, without considering the supply of parts, we can assemble 20 sets of power armor in 14 hours a day."


    In fact, this figure is a bit exaggerated. Under normal circumstances, the factory production line can not be transported to this production efficiency at full load.


    After all, there are quite a lot of parts required for power armor, which need to be produced in different factories and finally transported to the assembly factory for assembly.


    However, even if the country now concentrates a lot of resources, the operation efficiency of the factory production line is only a little more than 80%, because there is a lack of enough parts to make the production line run.


    This is mainly because of the shortage of resources. Now that the country is in a state of war, it is reasonable to concentrate all resources on the production of such war materials.


    However, with the change of the current situation, there are many places that need to invest resources. In addition to the production of war materials, there are many places that need resources.


    In addition, due to the unbalanced distribution of resources in China, a large number of resources need to be transported before they can be gathered in production plants. In order to avoid the waste of a large number of resources due to transportation, the country can only adopt the principle of nearby distribution as far as possible, which also leads to a large number of factories not getting enough materials to meet the needs of full capacity production.


    The high-level representatives naturally understood this, so when the workers said that they could assemble 20 sets of power armor a day, they naturally converted it into the actual output.


    But even judging by the actual production speed, the speed of 3D printing is still a little slow.


    Of course, this is not the key to the problem.


    "Academician Chen, how long will it take for a complete set of 3D printing equipment to produce a set of power armor?" the high-level representative asked Chen Xin this question.


    When he asked this question, the military representative went to the front of the two sets of power armor, reached out and knocked the two sets of power armor to check their quality.


    "In fact, it''s so fast. The advantage of 3D printing equipment lies not in its production efficiency, but in that it can produce anything when there are enough raw materials." Chen Xin explained to the representatives of senior management and the representatives of the military "The 3D printing technology I use is slightly different from the existing printing technology. It does not use laser welding powder printing, so it can print with a variety of materials, but it also brings a problem that more materials are needed for printing, not just one.


    Production efficiency is a big problem. It is destined not to replace the existing production lines. Therefore, 3D printing technology can be used on land aircraft carriers. They need to persist in the European battlefield for a long time and provide assistance to European countries. It is very useful to bring such a set of equipment.


    However, this technology is not suitable for domestic production. It is like having a machine that can make everything, but taking it to make only one thing. It is a waste.


    Research departments are still suitable for the use of 3D printing technology. Sometimes they need to produce some non-standard things or temporarily processed things. At this time, they only need to input drawings and dimensions into the 3D printing equipment to get what they want. It is undoubtedly much better than going to someone to produce, process and customize. "


    In fact, this is also the advantage and disadvantage of 3D printing. It is good to be able to print everything, but it also limits the application of 3D printing in production.


    After all, the processes and processes needed to produce a product are fixed. What is needed is to maximize production efficiency and produce what is needed quickly and in large quantities.


    At this time, instead of using a machine that can make everything, it is better to build a production line dedicated to producing this product.


    In fact, this is the same concept as the difference between using industrial machines to directly produce products and using industrial machines as a production line to produce products.


    It is not impossible to do so, but it is obvious that the latter can give more play to production efficiency and the advantages of 3D printing technology.


    After Chen Xin''s explanation, the senior representatives obviously understood Chen Xin''s meaning, but after a more detailed understanding of the various details of the 3D printing technology put forward by Chen Xin, they left with satisfaction.


    On the contrary, the military side, looking at a set of 3D printing equipment, suddenly had an idea of coquettish operation.
