"I think Mr. Su was also forced to have no choice. The director of the sales department sighed, "Medtronic raised prices, and our profit margins were reduced again. The board of directors can't explain it at all, and it is said that the board of directors already has some opinions on Mr. Su. ”

"Is this a dead horse as a live horse doctor?" said a vice president, "Forget it, let's see." When this so-called 3D printer arrives, see what it can print. ”

A few days later, Du Mingxuan came with some technicians from Z Time and Space, and at the same time, they also brought a 3D heart stent printer specially designed by them.

In this research and development process, Du Mingxuan also made a great effort, including the three-dimensional generation of cardiac stents, model comparison and material processing, otherwise this thing would really not be completed!

Flying Bird Medical Device Research Center, Cardiac Stent Project R&D Zone.

Today, I heard that Su Xueyan spent a lot of money to develop the product with Z time and space, and many high-level executives came to watch.

Not only them, but even two group directors.

Hao Hongyang and Xu Yuan are both members of the board of directors of Flying Bird Medical Device Group, and their voice in the board of directors is not low.

"Xueyan, I heard that you have invested in a new project, so come to take a look, no problem, right?" Hao Hongyang is an old man in his sixties, not tall, but very decently dressed.

"Like Hao Dong, I'm also curious, let's take a look. "Xu Yuan is relatively young, about the same age as Su Xueyan.

When the printer arrived today, Su Xueyan did not notify the board of directors, after all, this thing has not started the experiment yet. These two must have heard the news reported by others and came to see it.

This puts Su Xueyan under a lot of pressure, if there is a problem with the product, it is conceivable that the next time the board of directors meets, these two will attack him!

"Hao Dong, Xu Dong, although you see, I am still very confident in this product. Su Xueyan said generously.

On the side, Du Mingxuan said: "Believe me, I won't let Mr. Su down! Our products are made after repeated experiments, and there will be absolutely no problems!"

"Then I'm really curious!" Hao Hongyang made a curious look, "3D printer, new gadgets!"

The other high-level officials who came to visit did not speak, but looked at the so-called 3D heart stent printer with suspicion. Is this thing really that amazing?

"Don't say much, Director Zhu, let's start!" Su Xueyan instructed Zhu Jia of the R&D department.

"Good. Zhu Jia nodded and said to everyone: "Everyone, just now, we just learned the basic operation of this machine. It can be said that at present, its performance standards are very much in line with our requirements. ”

"Next, we will conduct a formal trial of cardiac stent printing!"

"This time, we're going to print the most difficult bioresorbable cardiac stent. In order to make the test results more informative, we selected a miniature pig as the object of cardiac stenting. ”

"The restenosis model after stenting in miniature pigs is basically the same as the histopathological changes in restenosis after PCI, so the miniature pig coronary artery stent implantation test is a very important test to evaluate the safety of stents. ”

"Based on the cardiovascular characteristics of this miniature pig, we printed a bioresorbable heart stent suitable for it, and then performed implantation surgery for observation. ”

Preparations were carried out intensively, and the research center prepared an eight-month-old healthy miniature pig for preoperative physical examination and data collection.

At this time, it is the turn of the 3D printer to start!

Du Mingxuan personally demonstrated and showed his company's technology to the senior management of Nok Group.

"3D printing is different from traditional manufacturing, and we can adjust the structure according to different printing needs. As we all know, the thickness of the blood vessel wall is different for everyone, so in order to make the most suitable product for patients, we first made a lot of investment in 3D vascular imaging technology!"

On the computer model, a three-dimensional image of the heart vessel wall of a miniature pig is being generated. The image is incredibly clear, with an accuracy of 0.01 mm.

"That's clear!" said one of Asuka's researchers, "It shows that the thickness of the blood vessel wall is 3.74 mm, but with our imaging technology, it can only show 3.7 to 3.8 mm!

"It's really a bit amazing! Our imaging instruments are imported from abroad!" Zhu Jia also felt very pleasantly surprised, imaging is the most basic requirement, if the imaging technology is poor, the manufacturing accuracy can not be improved.

Now we're starting to model the heart stent on this 3D image of the blood vessels. Du Mingxuan continued.

Their 3D printer comes with its own modeling software, and in the database, there are various model materials added by Du Mingxuan. After software modification, it is possible to produce the most suitable bracket model.

In just a few seconds, the 3D modeling of the heart stent was completed! This efficiency once again surprised everyone present!

"Modeling so fast!"

"Is this accurate?" asked Director Song of the product department.

"Of course it is accurate, the cardiac stent model displayed now is the optimal model selected based on the combination of blood vessel wall data and material data!

"I'm really looking forward to it!" Hao Hongyang, director of the Flying Bird Group, also said with interest.

Printing begins, and it's one of the hardest parts of the process.

Nok Group manufactures how to design cardiac stents, but they can't make them, because there are problems with accuracy and material handling.

"We use polymer materials, including polylactic acid, polylactide and polycaprolactone, which are all degradable materials that have been approved by relevant departments to be implanted into the human body, so there is no policy problem in the selection of materials. ”

"Next, it's time to witness the miracle!" Du Mingxuan said the magician-like line and asked his subordinates to start operating the 3D printer.

The materials are ready, the model is complete, and the printer is started!

Tell the nozzle to stack these degradable polymer materials in an ingenious way and combine them with each other.

Almost at a speed visible to the naked eye, a new, exquisite, new generation of bioresorbable cardiac stent appeared in front of everyone!

"It's printed!" exclaimed a researcher in surprise, one of the senior members of the cardiac stent development team.

When doing the heart stent molding, he didn't know how much trouble he had encountered, and he failed again and again, which made him suffer in his heart!

And now, he saw that the problems that his team had not been able to overcome were solved so easily!

In just a few seconds, these intractable polymer materials have been shaped into cardiac stents, how can he not be amazed?

Not only him, but Zhu Jia and others also opened their pupils, looking at this newly baked result!
