In the manufacturing building of the manufacturing area of the engineering department of Longinus College, Ye Lan is standing in front of a machine near the window in the workshop dedicated to practical teaching, studying how to use this thing with Mia.

said it was a workshop, but there was no assembly line in sight, and there were no assembly line workers wearing masks and uniforms. Some are just a student with a curious face and a 3D printer.

The small scale of this workshop only accommodates only 30 integrated automatic printing equipment, which is just enough to meet the needs of an entire engineering class. In fact, in terms of management, these machines are directly assigned to people, and each student only has access to their own machine, and at the same time, if the equipment is damaged due to operation error, it is convenient for the academy to trace the responsibility.

Ye Lan and her new friend Mia were assigned to a group and jointly owned the right to use the machine in front of them. Their task today is to complete the task given by their mentor - to do what they are asked to do, to make a finished product that meets the standards, and then to design an item and print it out on a printer.

Of these two items, only the first one is a mandatory requirement that the finished product needs to be handed in. The other one, on the other hand, looks more like cultivating the students' own creativity and does not ask for feedback on the results.

It depends on whether the student is really interested in the thing, although not asking for the hand-in may be largely for the sake of the children who have little design talent......

It is not possible for the instructor himself to accept every student's "debut artwork......

Without further ado, at least for now, the progress of their group is going well. Ye Lan skillfully prepared the raw materials according to the operation process and injected them into the machine; The indicators of the machine were checked to confirm that all components were in top condition; After completing the various startup operations according to the process, I waited for Mia on the other side to design the model, and then pressed the "print" button.

But Ye Lan waited for a long time, but still didn't wait for a response.

As she sat in her seat, she tilted her head to look over to Mia's side to see how her modeling was going.

When she saw what Mia was doing now, even though it was Sister Ye Lan, who had always had a good temper, she couldn't help frowning: "Hey, when is it, are you still scrolling through the forum?" ”

That's right, this amazing female student Mia, when she should be concentrating on modeling the 3D printer, is brightly using implanted crystals on the academy forum, and with Ye Lan's impression of her, she should be either reading gossip or writing her own posts to spread rumors. If it weren't for Ye Lan's group with her at this time, in a close and direct connection, if she could observe the other party's crystal work process, looking at her serious appearance, most likely would think that she was showing her talent in the modeling program. Who told others not to see the window opened by the crystal user?

Mia smiled nonchalantly: "I just went to the forum to post my experience, as for such a fuss?" You see, there have been dozens of likes, and more than a dozen seniors have encouraged me and taught me how to use it! ”

Ye Lan shook her head helplessly, deciding not to be serious with her friend who was like a living treasure, hoping that the so-called experience she had learned could make up for the lost exploration time.

Mia seems to have finally realized her gaffe and started to get down to business, concentrating on the modeling program in front of her.

Although modeling, which sounds like a high-end technology, may be far away from the average person. Women who learn to model are a rare resource in a sense. However, the cadets of Longinus Academy have never been ordinary people.

All the knowledge about modeling has entered their minds with the crystals, and all they have to do is reproduce these things.

It's just that the time will vary from person to person, and the higher the degree of restoration, the faster it will be completed. If the degree of restoration is low, the progress will be slower, but with enough time, the work can be completed eventually.

Thanks to the immersive display and simple mind control mode of the implantable lens, these tasks that should be relatively boring can be created as if they were being made as if they were being made into art, and the various tools are also easy to use. After a while, Mia completed the modeling according to the three views and the relevant parameters given by the tutor, such as density, mass, and materials used.

With Mia handing out a finished look, Ye Lan silently read and pressed the print button.

Immediately after that, the 3D printer began to work quickly. The titanium powder stored in the container is gradually extracted down the pipe, starting from the spout and ejecting outward little by little. Each time the robotic arm carries a spout swept over the bottom plate, it leaves behind a layer of sintered titanium alloy, and when the spout passes through again, a new layer is bonded to the previous layer.

It is precisely because of this layered stacking design that the 3D printer can restore the model as a physical object. This work must be done at the time of modeling, and the finer the division, the higher the accuracy of the nozzle, the higher the "resolution" of the finished product, and the finer the typed things.

As the spout completes the final layer of ejection, a resemblance dagger appears on the base, complete with a delicate structure such as a blood trough. But now it can't be used, it can only be regarded as a semi-finished product, and it still needs to go through several more processes.

Sure enough, the dagger was immediately fed into another instrument along with the base to optimize the strength of the material. It didn't take long for a dagger with a flickering cold light to be handed back. This is followed by the shaping of the second material......

In the end, the graphene material on the handle of the dagger was also fully formed, and the 3D printed dagger was completely completed, and it did not take too long from start to finish.

Ye Lan picked up the dagger, waved it in the air a few times, and nodded with satisfaction. This thing that they designed indiscriminately, not to mention that it can reach the level of actual combat, at least it is completely enough as an ornament. After Mia took the dagger, she immediately took a picture of it and posted it on the forum......

In any case, it should be more than enough to deal with the teacher's review. Then, the next step is to design an object completely by yourself, which is not the same as the dagger that has already been practiced and demonstrated, it is a completely new product, so it is very likely that the desired effect will not be achieved when it is manufactured. However, in order to ensure success, it is not possible to simply punch a metal block out indiscriminately, which will make 3D printing lose its value, such a simple part, traditional manufacturing methods can do the job.

Out of the principle of cooperation and learning from each other, this time it was Ye Lan's turn to model and Mia to operate. But what exactly is to be made? After thinking for a while, an answer slowly emerged in Ye Lan's mind.
