"I think President Su is forced to do nothing," sighed the director of the sales department. "Medtronic raises the price and our profit margin has been reduced again. The board of directors cannot explain at all. It is said that the board of directors has some objections to President Su."

"Is this a dead horse a living horse?" said a deputy general manager. "Forget it, let's look. When this so-called 3D printer arrives, see what it can print out."

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

Du Mingxuan also made great efforts in this research and development process. His contributions were made to the three-dimensional generation of the heart stent, model comparison and material processing, otherwise this thing would not be completed!

Feiniao Medical Device Research Center, Heart Stent Project R&D Zone.

Today, I heard that Su Xueyan spent a lot of money to develop products with Z time and space, and many senior 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 Feiniao Medical Devices Group, and the two have a good say in the board of directors.

"Xueyan, I heard that you have invested in a new project. Come and have a look. Is it okay?" Hao Hongyang is an old man in his sixties. He is not tall but dressed very well.

"I am just like Dong Hao, and I'm also curious, come and take a look." Xu Yuan is relatively young, about the same age as Su Xueyan.

The printer arrived today, and Su Xueyan did not notify the board of directors. After all, the experiment has not started. These two people must have heard the news reported by others and came here to see it.

This puts a lot of pressure on Su Xueyan. If there is a problem with the product, it is conceivable that these two people will attack him at the next board meeting!

"Dr. Hao, Mr. Xu, even if you look at it, I am still very confident in this product." Su Xueyan said generously.

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

"Then I'm really curious!" Hao Hongyang looked curious, "3D printer, new stuff!"

The other senior executives who came to visit did not speak, but looked at the so-called 3D heart mount printer with doubt. Is this thing so magical?

"No more say, Director Zhu, let's start!" Su Xueyan ordered Zhu Jia from the R&D department.

"Okay." Zhu Jia nodded and said to everyone: "Everyone, we just learned about the basic operation of this machine. It can be said that at present, its performance standards are very consistent with our requirements."

"Next, we will conduct a formal heart stent printing test!"

"This time, we are going to print the most difficult bioabsorbable heart stent. In order to make the test results more reference, we chose a small pig as the placement object for the heart stent."

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

"We printed out the bioabsorbable heart stent suitable for this small pig based on the cardiovascular vessels, and then performed an implantation surgery for observation."

The preparations were under intense urgency. The research center prepared eight months of adult healthy pigs, and conducted preoperative physical examinations and data collection.

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

Du Mingxuan personally demonstrated and showed the company's technology to the senior executives of Feiniao Group.

"3D printing is different from traditional manufacturing. We can adjust the structure according to the different needs of printing. Everyone knows that the thickness of the blood vessel wall of each person is different, so in order to create the most suitable products 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 blood vessel wall of the small pig is being generated. This image is extremely clear and has an accuracy of 0.01 mm.

"It's so clear!" A researcher from Asuka sighed, "It shows that the thickness of the blood vessel wall is 3.74 mm. With our imaging technology, it can only be displayed to 3.7 to 3.8 mm! This has improved by a decimal point!"

"It's really awesome! Our imaging instruments are imported from abroad!" Zhu Jia was also very surprised. Imaging is the most basic requirement. If the imaging technology is poor, the manufacturing accuracy will naturally not be improved.

"It's more than that! Now we will start modeling the heart stent on this three-dimensional image of blood vessels." Du Mingxuan continued to introduce.

Their 3D printer comes with its own modeling software. In the database, there are various model information added by Du Mingxuan. After the software modification, the most suitable bracket model can be produced.

In just a few seconds, the three-dimensional 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 Products Department.

"Of course it is accurate. The heart stent model displayed now is the optimal model selected based on the combination of the data of the blood vessel wall and the data of the material! Print it out according to this, there is no problem!" Du Mingxuan said.

"I'm really looking forward to it!" Hao Hongyang, director of Feiniao Group, also became interested and said.

Printing begins, and it is the most difficult process.

How to design a heart stent when Feiniao Group manufactures, but they can't make it, because there are problems with accuracy and material handling.

"We use polymer materials, including polylactic acid, polylactide, and polycaprolactone, which have been approved by relevant departments to implant into the human body, so there are no policy issues in the selection of materials."

"The next time is the moment 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 completed, and the printer is started!

Tell the spray head to stack these human body's degradable polymer materials in a clever way and combine them with each other.

Almost visible at a speed of naked eyes, a new, exquisite, new generation of bioabsorbable heart stent appeared in front of everyone!

"Print it!" A researcher shouted in surprise. He was one of the senior members of the Heart Stent R&D team.

When he was doing heart stent molding, he didn't know how many troubles he had encountered. The failures again and again made him suffer in his heart!

And now, he saw that the problems that his group had not overcome were solved so easily!

In just a few seconds, these difficult-to-treat polymer materials were molded into heart stents. How could he not be amazed?
Chapter completed!
