Materials with hardness not exceeding three can be printed?
Yang Yuan had previously looked at a hardness chart representing materials.
That is:
If talc's hardness is one, then gypsum's hardness 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.
So, in this sense, the hardness of these three points is quite basic, probably even ordinary metals can't be printed.
Yang Yuan had anticipated this, as he didn't plan on using the basic version to print high-quality materials anyway.
The engineer next to him said: "Assembly is complete. If there are any issues later on, you can call me. Whatever blueprints you need, just have someone draft one, input it, and it will automatically analyze the parts, letting you print them by placing the materials in, but this basic version of the 3D Printer cannot print chips or precision parts, plus the material hardness should best not exceed three points, otherwise it may malfunction."
"Alright, I'll keep that in mind, thank you." Yang Yuan expressed his gratitude.
"It's part of my job."
The engineer smiled and said goodbye before leaving.
Once the engineer left, Yang Yuan immediately opened the basic blueprints that came with the printer.
These blueprints were all for small toys, like Ultraman and Iron Man, and even Doraemon.
But these items are all whole pieces, put in as test prints, ordinarily nobody would use a 3D Printer to print such cheap things.
However, Yang Yuan didn't mind, he directly grabbed a handful of fallen leaves from the ground and placed them in the material bin, then selected Doraemon to start printing.
The printer started to hum with the sound of 'buzz buzz'.
After the buzzing ended, there was the sound of 'swish swish'.
About a minute later, a gray-black Doraemon, the size of a fist, appeared at the output port.
Yang Yuan picked up the Doraemon toy to take a closer look, and sure enough, it was quite exquisite, every detail was printed nicely.
If it were sold on Earth before merging with this world, such a delicate toy could sell for at least a hundred bucks each.
[3D Printer Lv.1: 1/40 (Not Upgradeable)]
"So, the way this printer gains experience is by printing one point per print?"
Yang Yuan smiled slightly, then directly set it to print thirty-nine more Doraemons.
Having set the program, he kept filling the material bin with fallen leaves, treating this waste as material.
After all, it was just about gaining experience, increasing the count, quality wasn't necessary.
"Wow..."
"Yikes!!"
"So cool!!"
Suddenly, cheers erupted from the factory gate.
Six little girls whom the soldiers had helped call over had arrived, the youngest was only five or six years old, the oldest was no more than nine years old.
As soon as they entered the cooling unit's radiation range, they showed expressions of disbelief, as it had been a long time since they had felt such coolness.
"Give them two additional outfits and blankets to note in the account, now they might feel cool but soon they will feel cold."
Yang Yuan spoke to the soldier who brought them.
"Okay."
The soldier nodded; after all, once the high temperatures and water problem were solved, and being stuck here with nothing to do, those who couldn't go out also became idle, manpower was now sufficient.
Nowadays, apart from Superpower Users who have broken through at least one limit, others would be roasted once they leave the safe zone.
Soon, the six little girls who had lost their loved ones or got separated from them moved into the safe house's three small compartments, starting to brush up on experience for the safe house.
And Yang Yuan here was not idle, after filling the material bin with fallen leaves, he picked up a dry twig, plucking the layers of fallen leaves in the workshop together, as these were his raw materials.
The white-haired, white-eyed Storm Lady watched this from afar, puzzled that layers of fallen leaves could even be used as material?
Wasn't that person cutting corners?
Wasn't this too blatant?
However, she only knew that orders were placed from above with Yang Yuan, not what orders were placed, so she didn't try to expose Yang Yuan's suspected corner-cutting behavior, continuing to maintain her cold persona like a steadfast figure.
Soon, half an hour passed, and the set thirty-nine Doraemons were all printed out.
Yang Yuan came to the printer, saw the experience was full, and directly upgraded.
This 3D Printer being a quick and rough job, hence no coloring or anything, everything was still the color of the raw material, giving an impression of bold strokes.
And with the upgrade, visibly, the printer's shell became a bit more sophisticated.
Soon, the upgrade ended, and the experience data changed to:
[3D Printer Lv.2: 0/80 (Basic edition 3D Printer, able to print materials with hardness not exceeding 4; Not Upgradeable)]
Yang Yuan smiled slightly.
Other people's machines get worse with use, but his machine gets stronger.
No doubt in a while, this printer will be able to print any material.
By then, his speed of gaining experience will surely greatly increase.
This time, he set directly three hundred and forty Doraemons, intending to gather enough experience to upgrade to Level 4 in one go.
If not worried about the machine malfunctioning, he would have set thousands in quantity.
It's worth mentioning that after reaching Level 2, the printer's work efficiency increased a bit, the printing speed was slightly faster.
At this point, Zhao Jiayan came back with Jiang Yiyi, followed by a group of people helping to transport things.
Zhao Jiayan did buy a lot of stuff, but being frugal, in the end, she didn't spend big money, just expending three human-level Spirit Monster Cores.
She was surprised that a human-level Spirit Monster Core was equivalent to a hundred ordinary Spirit Monster Cores.
So, this time going out, she spent three hundred ordinary Spirit Monster Cores, never having been so extravagant before.
However, when Yang Yuan saw the purchased items, he was somewhat dissatisfied: "Why are they all daily necessities? There should be a lot of good stuff in the safe zone, right? Like things to strengthen power, your strength is too weak, if there is anything that can strengthen power, it would be best to buy more, also snacks, don't you girls like to eat snacks?"
Zhao Jiayan laughed while crying: "Even the safe zone, no matter how extravagant, wouldn't waste food to make snacks under these circumstances, right?"
"Alright, in short, don't be too frugal, having too much money is useless, if we don't spend it fiercely, it's a shame."
Yang Yuan said, taking some Doraemons from the printer and handing them to Jiang Yiyi: "Yiyi, these are toys for you."
Jiang Yiyi's eyes lit up, happily taking them: "Thank you, big brother."
Obviously, she really liked Doraemon, even if it wasn't colored.
"There are many more of these toys; you can take them to the safe house where there are six children and play together."
Yang Yuan patted the little girl's head, as the reason why he wanted little girls was to find a playmate for Jiang Yiyi, to prevent her from having personality defects due to extended time without playing with peers.
"You even considered such things." Zhao Jiayan said in surprise.
Yang Yuan smiled. He wasn't someone who struggled for three years in this world, but had just crossed over, so many times his way of looking at things was different from others.
Jiang Yiyi took the Doraemon toy to the door of the safe house, looking at the six children inside.
The six little girls also eagerly looked at her, mainly at the Doraemon toy in her hand, clearly wanting it but not daring to speak first.
