During the replenishment of water in the space shelter, Su Tianzong naturally couldn't leave the dormitory and leave the space door alone. Simply block the broken door of the dormitory with a standing cabinet to prevent anyone from breaking in and seeing the door of the space. After lying on the waterbed and sleeping for six hours, Su Tianzong planned to take inventory of the items in the basic material warehouse to confirm what else he needed to buy.

There are a variety of raw materials and powder particles stored in the warehouse, including various metals, dozens of plastics, different kinds of rubber, fibers, building materials, etc., which occupy 60% of the space in the warehouse, and are consumables for 3D printers. Su Tianzong found the two portable 3D printers and said that they were portable, but these things were the size of two desks, and they were still folded, completely expanding the space of at least five meters square for Xu Tao. Su Tianzong pushed one of the 3D printers out of the warehouse, found a suitable open space, and carried out the operation.

The unfolding of the 3D printer is also a virtual projection that shows the unfolded form in advance, and then determines the unfolding position. Once the command is confirmed, the portable 3D printer on wheels automatically moves to the preset position, releases all the auxiliary drones it is carrying, and executes the deployment command.

Ten minutes later, a new building five meters wide, six meters long, and four meters high appeared inside the space shelter. The 3D printer looks very rudimentary, with lots of exposed frames and a three-meter-sized printing platform. But it's so powerful that it can print hundreds of different types of materials, and you can mix different materials for fusion printing. The size of the printed items can be in the range of up to three cubic meters and as small as nanometers.

"How does this thing turn on?" Su Tianzong searched around but didn't find a switch there.

"Please unfold the wireless power supply device and align it in the direction of the basic energy module."

A sign immediately appeared in front of Su Tianzong's eyes, pointing to a small device in the corner. He followed the prompts to unfold the receiver of the wireless power supply device step by step, and found that this thing had a curved metal plate like a radar antenna, and it could also rotate significantly. Immediately after pointing in the direction of the base energy chamber, a blue indicator bar lights up, indicating that energy transfer is in progress.

The 3D printer immediately seems to come to life, the various mechanical systems start to self-check, and several material printheads automatically move to the initial position. A light screen appears on the front of the 3D printer, showing the status of the machine. The print material has not been installed yet, so all are shown as vacant. After the self-test is completed, the printer enters the standby state and waits for the user's control.

"Is there anything I can print?"

"There are no 3D models stored in the 3D printer, so please prepare the 3D models before you start printing."

"3D models? I'm good at this. Su Tianzong took out his laptop, took out a mobile hard disk and connected it to the computer, and found the folder of 3D animation course works from the hard disk. When studying game design at the academy, 3D art is a compulsory course, and making 3D models is Su Tianzong's forte.

"ZX, scan the data from these models."

"During the data inspection, a large amount of 3D model data was found, did you convert this data into 3DX format and store it in the database of the space shelter?"

"Well, execute."

"When data conversion begins, please do not shut down the electronic system of the data source."

Su Tianzong returned to the side of the 3D printer, and the printable list displayed on the light screen was originally nothing, but now it was gradually filled with the data of Su Tianzong's practice works. He chose a pistol as the target for printing, a K1911 classic pistol that could be loaded eleven pieces and used 0.45 caliber bullets. The three-dimensional model of this pistol contains a complete internal structure and is one of Su's favorite firearms works.

Once the pistol is selected, the data is automatically analyzed by the 3D printer's control system to select and optimize the material for all parts individually. Su Tianzong watched those parts being marked with material properties one by one, and his heart became very excited. With this 3D printer, as long as he can make a 3D model, he can make anything he wants. Of course, the premise is that the material is enough, otherwise it will not be printed.

"ZX, I'm printing a weapon, will there be any restrictions on my civilian status?"

"This primitive charge-propelled weapon is not covered by the human republic weapon restriction law, and according to the regulations, the attack power exceeds the protection ability of the lowest-level nano-exoskeleton used by individual citizens."

"Primitive Weapon ......" Su Tianzong's main weapon in this era is probably a group of natives with primitive weapons in the eyes of the human republic, and this gap is inevitably too big.

The 3D printer made a soft sound, indicating that the 3D data of Su Tianzong had been analyzed and could be printed. Su Tian glanced at the list of consumables demand, iron accounted for the majority, followed by copper, aluminum, titanium, nickel, cadmium and other metal materials, as well as carbon fiber and plastic as additional materials. It takes 32 minutes to print, which is a very fast speed.

In Su Tianzong's world, 3D printing is still in its infancy, the printing material is very single, and only plastic, rubber and some metal materials can be used, the printing speed is very slow, and it is possible to shoot a gun for a few days. It is basically impossible for a 3D printer like the one in front of me to print so fast with mixed materials.

Su Tianzong casually clicked on a three-dimensional model of a bullet and asked the three-dimensional printer to analyze it. The analysis of the bullet was very fast, and it was done in a few seconds. 3D printers can print bullets and cartridge casings, as well as a firing cap on the bottom of a bullet. Primer is a chemical that 3D printers can't do anything about.

Su Tianzong stretched out his hand and pressed the confirmation print button on the light screen, and the three-dimensional printing, which was originally quiet and standby, became busy instantly, assisting the drone to fly to the basic resource warehouse to extract the materials required for printing, and the printing platform automatically entered the leveling state to ensure the accuracy required for printing. The various mechanical devices also enter the pre-print preparation work, most of which are self-tested and preheated, waiting for the material to arrive.

Looking at the fast-working machine, Su Tianzong was a little more sure of survival, because the period when there were no weapons to use was coming to an end.
