Can only materials with hardness no more than three be printed?

Yang Yuan has seen the hardness table representative of materials before.

That is:

If the hardness of talc is one, then the hardness of gypsum is two, calcite is three, fluorite is four, apatite is five, feldspar is six, quartz is seven, topaz is eight, corundum is nine, and diamond is ten

.

From this point of view, the hardness of these three points is really basic enough, and it is estimated that even ordinary metal cannot be printed.

Yang Yuan had expected this. Anyway, he had no intention of using the basic version to print high-quality materials.

The engineer next to him said: "It has been assembled. If you have any other questions later, you can call me. What drawings are needed? Just ask someone to draw one and input it. The parts will be automatically analyzed and the materials can be printed out. But

This basic version of the 3D printer cannot print precision parts such as chips, and the hardness of the material should not exceed three points, otherwise it will easily malfunction."

"Okay, I'll remember it, thank you." Yang Yuan thanked him.

"This is my job."

The engineer smiled, said goodbye and left.

After the engineer left, Yang Yuan immediately opened the basic drawings that came with the printer.

These drawings are all small toys, such as Ultraman, Iron Man, and even Jingle Cat.

But these things are all integral and are drawings put in for testing purposes. Under normal circumstances, no one would use a 3D printer to print such cheap things.

However, Yang Yuan didn't mind it. He grabbed a lot of rotten leaves from the ground and put them into the material bin. Then he selected Jingle Cat and started printing.

I heard the printer buzzing.

After the buzzing sound ended, there was another "swish" sound.

About a minute later, a gray-black fist-sized jingle cat appeared at the discharge port.

Yang Yuan picked up the Doll Doll Cat and took a look at it. Not to mention, it was quite exquisite, and every detail was printed out.

If sold on Earth before integrating into this world, such exquisite dolls would fetch at least hundreds of dollars each.

[3D Printer Lv.1:1/40 (not upgradeable)]

"So the way this printer gains experience is by printing a little bit of experience at a time?"

Yang Yuan smiled slightly, and then directly set up to print thirty-nine jingle cats.

After setting up the program, he kept putting rotten leaves into the material bin, treating the garbage as materials.

Anyway, it’s just about gaining experience and the number of times you gain it, it doesn’t require any quality.

"Wow……"

"ah!!"

“So cool!!”

Suddenly cheers came from the factory gate.

It was the soldiers who helped call six little girls here. The youngest was only five or six years old, and the oldest was only about nine years old.

As soon as they entered the radiation range of the cooler, they looked in disbelief because they didn't know how long it had been since they had been so cool.

"Give them two more clothes and a quilt, and put them all in the account. They feel cool now, but they will feel cold later."

Yang Yuan said to the soldier who brought the people over.

"OK."

The soldier nodded. Anyway, the high temperature and water problems were suddenly solved, and since they were stuck here and couldn't do anything, those of them who couldn't go out were all free, and now they had enough manpower.

Nowadays, except for the superpowers who have broken through the limit at least once, everyone else will be roasted directly as long as they leave the safe zone.

Soon, the six little girls, who either lost their relatives or were separated from their relatives, moved into the three small compartments of the safe house and began to gain experience in the safe house.

And Yang Yuan was not idle here either. After he filled the material warehouse with rotten leaves, he picked up a dead branch and picked up all the rotten leaves in the entire factory. These were his raw materials.

Storm, who had white hair and white eyes, watched this scene from a distance, wondering in her heart, how could the layer of rotten leaves that can be seen everywhere be used as material?

Is that guy trying to cut corners?

Is this too blatant?

However, she only knew that her superiors were going to place an order from Yang Yuan, but she didn't know what the order was, so she didn't try to expose Yang Yuan's suspected behavior of cutting corners, so she continued to maintain her cold persona and stayed there.

Be sure to fix the Fengshen needle.

Soon, more than half an hour passed, and all the thirty-nine jingle cats that had been set were printed out.

Yang Yuan came to the printer and saw that he had full experience, so he upgraded directly.

Because this 3D printer is a quick and rough job, there is no dyeing at all. Everything is still the color of the raw materials, giving people a drastic feel.

With the upgrade, visible to the naked eye, the printer's outer shell has become more refined.

Soon, the upgrade was completed and the experience data became:

[3D printer Lv.2:0/80 (basic version of 3D printer, can print items with material hardness no more than 4; cannot be upgraded)]

Yang Yuan smiled slightly.

Other people's machines become worse and worse with more use, but your own machines become stronger with more use.

I think it won't take long for this printer to be able to print any material.

By then, the speed at which you can gain experience will definitely increase greatly.

This time, he directly set up three hundred and forty jingle cats, preparing to upgrade to level four in one fell swoop when he gathered all the experience.

If he wasn't worried about machine failure, he would have set the number in the thousands.

It is worth mentioning that after upgrading to Level 2, the printer's working efficiency has improved a bit and the printing speed has accelerated a bit.

At this time, Zhao Jiayan came back with Jiang Yiyi, and behind them there was a group of people helping to carry things.

Zhao Jiayan did buy a lot of things, but as she was used to saving, she was still reluctant to spend a lot of money. She only spent three human-level spirit cores.

What surprised her was that one human-level spirit core was worth a hundred ordinary spirit cores.

In other words, she spent 300 ordinary spirit cores during this outing, and she had never been so lavish.

However, Yang Yuan was a little dissatisfied after looking at the things he bought: "Why are they all daily necessities? There should be a lot of good things in this safe zone, right? For example, to improve your strength, your strength is too weak. If there is something that can improve your strength,

It’s best to buy more things and snacks. Don’t you girls like snacks?”

Zhao Jiayan said dumbfounded: "No matter how extravagant the safety zone is, we won't waste food and make snacks under such circumstances, right?"

"Okay, anyway, don't be too frugal. We keep too much money for no use. We have earned it so hard, and if we don't spend it ruthlessly, we will be sorry for ourselves."

As Yang Yuan spoke, he took out a few jingle cats from the printer and handed them to Jiang Yiyi: "Yiyi, these are toys for you."

Jiang Yiyi's eyes lit up and she happily took it: "Thank you, big brother."

Apparently she really likes jingle cats, even undyed ones.

"There are many more toys like this. There are six children in the safe house. You can take them and play with them."

Yang Yuan touched the little girl's head. The reason why he only wanted a little girl before was to find a playmate for Jiang Yiyi, so that the little girl would not develop character defects if she did not play with her peers for a long time.

"You actually even considered this." Zhao Jiayan said in surprise.

Yang Yuan smiled. He was not a person who had been struggling in this world for three years, but someone who had just traveled through time. Many times, his way of looking at problems was different from others.

Hearing this, Jiang Yiyi walked to the door of the safe house with the Jingle Cat doll and looked at the six children inside.

The six little girls also looked at her eagerly, of course, mainly looking at the Jingle Cat doll in her hand. They obviously wanted it very much, but they didn't dare to take the initiative to speak.

[Please give me a monthly ticket and a recommendation vote!]

There were many inexplicable people who actually said that my recommendation votes were faked. I was really speechless. There were also other, some very speechless comments. Some people commented with content that I didn’t even know existed. I thought the other person was.

The boss came, and I was ready to discuss it with him, but I went to see his homepage and found that he had been registered for more than a thousand days, but he was still an ordinary user, not even an ordinary member.

So I set up a restriction on speaking, just a certain threshold of fan value. I believe that as long as people who really speak seriously will not care about this threshold.

Another point is that I will read book reviews very seriously, but writing book reviews will make my mentality explode, and it will easily make me not in the mood to write. Therefore, I will delete those book reviews after reading them carefully, and I am not interested in the person who posted the book review.

If you have any opinions, I would like to apologize here.
