3D printing pen is a new type of toy developed by human beings. With it, you can draw anything you want, just like the magic Ma Liang pen.
My 3D printing pen is about 14cm long and 3cm wide. It is a pink elephant. The tip of its nose is a discharge port, and its head is directly above the feed port. Its diameter is about 2. 5 mm, graphic, with charging port next to it.
There are two buttons on both sides of its nose, which is where it holds the pen. The keys below the index finger are the power-on key, the power-off key and the pause key. Press and hold for 3 seconds to turn it on and off, click to pause, and then click to continue. The button below the thumb can adjust the speed and control the powder discharging speed.
Consumables are a thin strip made of hard materials, as thin as the lead of a 2B pencil, and about 6 meters long, tied into a circle.
When in use, the consumables will automatically heat up when inserted into the inlet, and become soft and sticky after coming out. Can be coated on smooth surfaces such as paper and cabinets, and will harden and solidify in less than 2 minutes. After cooling, you can peel it off, and then draw a line with material on the edge to play the role of glue. Before it cools, stick what you want to stick on it and cool it.
The compact 3D printing pen makes home office more convenient and fast.

A few days ago, my teacher asked me to study 3D printing in No.2 Middle School of our school. As soon as I heard the good news, I couldn't help getting excited and rushing to tell you: I'm going to learn 3D printing!
I am very much looking forward to the arrival of the 3D printing class, and I really want to see what 3D printing is all about.
The first 3D printing class finally arrived under my eager expectation, and I was sitting in the laboratory with great excitement. The teacher brought an instrument with a big head and a small body. Is this a 3D printer? The teacher said it was a multimeter. Although I didn't see the 3D printing equipment, the hissing of the multimeter somewhat alleviated my disappointment.
In the second class, the teacher brought a pen with a strange shape and dragged a long wire under it. My heart is cold, and there seems to be no chance of 3D printing today. I didn't expect the teacher to say it was a 3D printing pen! I immediately got up after listening to it, and I was curious about how such a thick pen was printed in 3 D.
The teacher operates the 3D printing pen and paints on the pre-printed plane pattern, as if the senior chef is making a three-dimensional platter with various sauces and fruits. Just looking at it doesn't seem to be very enjoyable. The teacher seems to know what we think, so let's experience the operation in turn. Although the things I make are rough, holding my own printed 3D works makes me feel beautiful.
3D printing is not just a "three-dimensional dish platter". The teacher also taught us the fashionable shell of 3D printed slow flash diode in the later class. The teacher said that through the next study, we should "model" our ideas and then print out what we conceived in 3D.
I look forward to printing my "Science and Technology Entertainment Hall" in 3D one day, so that students can have fun and enjoy the speed and exquisiteness of 3D printing.

This summer vacation, I took two interesting classes, namely 3D printing and intelligent robot, among which 3D printing is the most interesting. Let me tell you something!
On the first day, I came to the children's palace classroom early and saw that every child had a computer and a printer. That's so cool! Everyone sat quietly in their seats waiting for class, eager to know what the teacher can lead us to print today. Finally, the class began. It turns out that today the teacher taught us to print apples. Well done! As soon as the teacher finished drawing the essentials, we couldn't wait to start doing it. According to what the teacher taught me, I first choose the curve instruction to draw a semicircle with two concave ends, and then I want to draw a straight line. At this time, the problem came. I ordered a straight line, but when I drew a line, I found that I drew a curve, and I drew it many times, but it was not a straight line. I am so depressed! But I never gave up. I tried again and again and finally succeeded. The original selection instruction must be correctly and continuously double-clicked, which really pays off! After painting, the figure is like an apple slice. Then I choose the command of rotational molding and enter 360 degrees. The apple slice immediately turned into a big apple, which is amazing! When the apple was printed, it was found that the big apple had no handle. Such apples are really rare! Now I have learned to print apples, vases, boats and beards. 3D printing is really interesting. There will definitely be more interesting projects waiting for me in the next class!
My father studies 3D printed materials. He said that now 3D printing has been gradually applied to medical, biological, military and other research fields, and will be more integrated into our lives in the future!
Children, if you also like 3D printing, let's play together!

I visited the Science Festival with a small group of reporters, and what interested me most was a 3D printer.
This printer is very different from what we usually see: it is rectangular and supported by four black pillars. There is a palm-sized square platform in the middle of the machine with a sharp nozzle above it. A black hard line was melted by the nozzle and slowly flowed to the platform. A three-dimensional octopus has gradually appeared on the platform.
A little sister explained to us, "Look, this octopus will be printed soon. These things are printed by it. " Wow, the table is full of minions, Charmander and rabbits with gold ingots. I picked up a 25 cm high minion and looked at it. I couldn't help crying. "It's so light!" After listening to my words, the elder sister smiled and said, "Yes, the things printed by the 3D printer are very light. Moreover, it also has its presence in the medical field! Plasters will be attached to the fracture, while ordinary plasters are heavy and airtight, making patients uncomfortable to wear, while plasters printed by 3D printers are light and breathable. "
After listening to my elder sister, I realized that 3D printers can also print clothes. In addition, many athletes have high requirements for shoes, and the shoes printed by 3D printers are soft and comfortable, which just meets their requirements.
After watching the exhibition, I thought: I will study science and technology seriously, and I will also serve the national science and technology development when I grow up.

In the evening, my father suddenly said to me, "Do you want to see the magic of 3D printing technology?" I asked my father, "What's the big deal?" Dad said, "Let's go and have a look tomorrow!" " "
The next day, I went to the museum with questions. As soon as I got off the bus, I couldn't wait to rush into the gate to see the true face of the 3D printer. However, as soon as I entered the museum, the first thing that caught my eye was a dazzling array of colorful clothes. Hey, what happened? Where is the so-called printer? I walked in and read the introduction carefully before I knew it. Oh, it turns out that these are all printed by a 3D printer, not sewn with traditional cloth. It's amazing! I looked further for traces of the printer.
It turns out that there are many kinds of 3D printers, and there are many different functions according to different products. Later, I saw that I could print delicious white chocolate that I could eat directly. All kinds of beautiful desk lamps; I also printed photos of our family photos on coffee, and my father and I drank them directly. It is really delicious! In addition to these things, 3D printing technology also has applications in other fields. For example, people's five senses, limbs and heart can be printed in medicine, and cars, planes and houses can be printed in industry.
Today, it really opened my eyes. 3D printing is amazing! I believe that the future 3D printing technology will be more mature, more precise and more energy-saving!

Ordinary printers are used to print words. But there is a printer called 3D printer. The 3D printer is a magical printer, which can even "print" a complete building. Do you want to experience the magical 3D printer with me?
Walking into the Science and Technology Museum of Wenzhou Middle School, there is a simple machine in the master's office. Don't underestimate this machine. This is a 3D printer made by Master himself. Although it looks unremarkable, you will know how amazing it is as long as you start working!
First, you should find a picture you want to print in the computer library, or you can draw a picture you want yourself. Then adjust the size by software, start peeling and calculate the printing time. If you print something big and tall, it will take a lot of time. If you print something small and flat, it only takes a few minutes to finish. Because the printer melts the materials by computer heating, and then stacks them layer by layer according to the pattern, the higher the level, the longer the printing time.
Next, I want to experience the 3D printer myself. I chose a picture of a bird in a cage, put it in the software, peeled it off and clicked Print. The printer starts to warm up. After about 1 minute, the temperature of the print head reaches 200 degrees, and the printer starts to work. It first moves its nose around the base, and then begins to draw, overlapping around the picture. First, the base of the birdcage appears, then a bird appears on the base, and finally a closed birdcage is printed. Birds were printed vividly, and a magical work was born.

Can you guess what day it is today? Today is "3D Printing Day"-I'm going to experience 3D printing myself! When I came to the dream town, I started my printing journey.
The teacher there told us that 3D means 3D in Chinese. "Look." The teacher held up the mouse pad and pretended to draw a dot on it. "This is one-dimensional. Like this cushion, it is two-dimensional." "Do you know how to use a pen?" We looked blank. "First, plug in the power supply; Second, heating, press the button near the pen tip next to the screen and wait for the blue light to light up; Third, insert silk. " Later, the teacher told us that Hull was the father of 3D printing.
I began to take action. I picked up a printing pen, plugged it in as the teacher said, raised the temperature, then inserted the silk (yellow) and pressed a button all the time, and the silk slowly came out from the beginning. I picked up my pen and tried to draw yellow lines on the paper, but the pen didn't even show any yellow lines. I can't help wondering: has Huang Si gone on strike? When the instructor came over, I thought, if you press the button twice or keep pressing it, you can't just press it. So, I pressed the button again, and sure enough, silk came out. Plumes of yellow silk covered the paper, and my heart became cheerful. When it was full, I decorated it with red and purple, then took the result down and glued it with silk. Ha, the glasses are finished! I tried it on and it was not bad!
Through this 3D printing, I understand that everything should be discovered by my own practice, so as to broaden my horizons and learn knowledge better!

On July 5th, the sun was blazing and there were no clouds in Wan Li. We came to China Charity Museum and started a wonderful journey of 3D printing.
The 3D printer is very small, about 60 cm high, and looks like a rectangular black box, but you can clearly see the sophisticated instruments through the glass baffle. A small mechanical arm is hung on the two sliding bars, and the blue base can rise and fall freely.
The class began. Looking at the pictures of magic works and listening to the teacher's humorous and vivid explanation, I couldn't help being fascinated. Ah, the teacher asked us to program! The hall boiled instantly. Another friend and I started the operation under the guidance of the teacher. On the computer, people and animals stand on the ground, and we can watch 360 degrees without dead ends as long as we gently move the mouse. I operate the keyboard, adjust the zoom factor and control the character size. After a while, a majestic Tyrannosaurus Rex was born. The teacher nodded and praised again and again, and let us observe the operation process of the printer at close range, which made me very happy.
The 3D printer works! The small manipulator slides back and forth flexibly on the sliding bar, and the nylon glass fiber filaments are spit out at the end, covering the work layer by layer. Gradually, the work became taller, the base suddenly slipped, the mechanical arm tilted, and more detailed production began. Before long, a delicate orange "OK" shape was printed successfully. You see, its texture is so smooth, the outline is clear and light.
We firmly believe that with the continuous development of human science and technology, 3D printing technology will continue to improve and mature, and will be applied to all fields of society in the future for the benefit of mankind.

With the continuous development of science and technology, 3D technology has been popularized in our lives. "3D printer" used to be a vague outline in my mind. Today, I had the honor to participate in the "scientific salad dressing" 3D small maker training activity, which gave me a deep understanding of 3D printing technology.
Although today's high temperature is unbearable, it still can't stop our little reporter's enthusiasm for understanding 3D technology. The little reporters all came to the pioneer camp of Xiaochuangke, a dream town in Chuanglin 3D. As soon as we entered the exhibition hall, we saw a dazzling array of 3D printed items, including exquisite necklaces, fun finger gyroscopes and medical dental models. We can't wait to try it ourselves.
At the beginning of the course, Mr. Zheng first introduced the work to be done today-three-dimensional bookmark in the form of interesting questions and answers. The teacher asked us to design a bookmark template we like on paper first, and then draw the same pattern in the computer according to the template. Finally, the plane pattern we draw is converted into three-dimensional pattern by using special software. I drew a bookmark with a carrot pattern, but some lines were not completely connected when designing. At this moment, Mr. Zheng came over. He gave me careful guidance and taught me to add thick lines to connect the letters in the pattern.
Finally, it's an exciting moment-printing works. The teacher copied my work to the 3D printer, pressed the "Start" button, and the printer worked hard. After printing for about 20 minutes, my masterpiece-a beautiful "carrot" bookmark appeared in front of my eyes, "Wow! How nice! " I can't help exclaiming.
This is really a fruitful 3D trip, which not only let me know about 3D technology, but also let me experience 3D, which opened a door for me to know the new world.

On Saturday afternoon, I participated in a small reporter activity of Niutong Society-3D printing experience. We saw a lot of strange equipment in the experience hall and couldn't help but want to touch it.
Aunt, the commentator, first introduced us to 3D printing as a rapid prototyping technology. It is a technology based on digital model file, using adhesive materials such as powder metal or plastic, and constructing objects by printing layer by layer. Secondly, the rapid prototyping principle and application fields of 3D printing are introduced. Finally, the commentator's aunt gave our little reporter a group of experiences in all aspects of 3D printing. Through these experiences, I learned that Fanda 3D printing is the first 3D printer in China, which can print out various items through scanning.
Guess what? Americans also printed the world's first human heart through 3D printing technology and made it beat like a normal human heart. It can be used as an exercise at present. Its advantage is that it can directly generate objects with arbitrary shapes from computer graphic data without mechanical technicians and molds, thus greatly shortening the product development cycle, improving productivity and reducing production costs.
Students, after listening to my introduction, are you interested in 3D printing technology? Then you might as well experience it! I'm sure you will like it.

I've heard of many 3D printing activities organized by Bao Xiao, but for various reasons, I didn't catch up with it. On Sunday, I finally experienced it myself.
In the afternoon, my parents sent me to the activity site on the ninth floor of Xiaoshan Daily. As soon as I entered the classroom, a lively atmosphere came to my face. I found a "golden" position and sat down. The teacher divided us into groups of eight. After a while, the teacher first sent us the tools and materials, and then told me how to use and make the tools. After the teacher explained, everyone began to "create" one after another, making their favorite works, some as cartoon characters, some as small animals, and some as buildings. I want to be a Mickey Mouse. First, I turned on the power of the 3D printing pen, inserted the colored plastic strip into the end of the pen, sent it to the nib through the button, and then started painting by heating. Because the colored plastic strips have been softened, they are obedient and at my mercy. On the white paper, I carefully draw along the outline of the pattern that has been built. Soon a lovely Mickey Mouse waved to me. Look! Its big ears are orange, its round belly is red and its oval eyes are black. How swaggering!
Finally, my work was praised by the teacher, and I was flattered. Walking on my way home, I felt the fallen leaves on the tree chasing me like a "butterfly" and rewarding me.

On Wednesday afternoon, a group of young reporters and I followed the headmaster to the laboratory of our school. When we walked into the laboratory, I saw a machine on the podium that I had never seen before. I thought, is this a 3D printer? When looking for a seat, the students talked a lot, and everyone was curious.
When we were all seated, a young teacher Li began to ask, "Classmates, does anyone know the name of this machine?" What can it do? " Everyone said in unison, "3D printer, it can print three-dimensional things." Then the teacher asked, "Who knows what 3D printing is?" No one answered, and the teacher turned on the computer. The files on the computer told us that 3D printing is actually just like printing documents in the computer, except that the printer we usually use prints words and images on paper, which is a process of plane printing, while 3D printing directly prints three-dimensional images in the computer into three-dimensional objects. "So what is the principle of 3D printing?" When the teacher asked, he showed us a picture with building blocks on it. At this time, some students raised their hands to answer. The principle of 3D printing is to add materials layer by layer. The teacher said, "That's a good answer." Then the teacher told us that the 3D printer does not use paper and ink, but melts pla plastic particles through a series of technologies, and then stacks these materials layer by layer to turn the 3D image of the computer into a real object.
Finally, the teacher showed us the working principle of the 3D printer. When I took a closer look, the machine began to run and the model slowly came out. It's amazing!

A few days ago, I excitedly came to Xiaoshan Museum to experience the magic of 3D printers.
At the entrance of the museum, all kinds of colorful flowers and bright green leaves came into view. But these didn't attract my attention. My heart has long been attracted by the mysterious 3D printing. I strode into the museum and soon found a place for 3D printing.
The homework began, and the teacher gave each of us a printing pen. She said to us with a pen: "This is a 3D printing pen, and we can use it to make anything we want! Let's put the silk through the hole at the back first, and then when the temperature of the pen reaches 185 degrees Celsius, we can start making. " After listening to the teacher's explanation, my interest increased tenfold in an instant and I couldn't wait to start making.
I was thinking about what to do with the pen when I saw a small flower. Well, just be a little flower! I first drew the petals of a small flower on the paper with a pen, but when I first used a printing pen, the line I drew was not so straight, but crooked. At this moment, my mother saw my troubles, and she came up to me and said, "Nuo Nuo, it doesn't matter! Take your time. There is still time. " So I slowly drew the outline of other petals and colored them, this time much better than before. It took me two whole hours to finish these flowers.
This 3D printing experience is so interesting! It is not like ordinary printing, but three-dimensional printing. I have a "magic pen" that happens to be a beam.

The invention of 2 1 century changes with each passing day, and high-tech products make our life more convenient. 360 portable WIFI makes it easier for us to surf the Internet, and the 3D printer invented not long ago has slowly entered our lives. Today, with curiosity, I went to Zhejiang Science and Technology Museum with my father to have a look.
When we arrived at the Science and Technology Museum, we took the elevator to the second floor. At that time, I was excited and looking forward to it. I thought it was amazing and thought: What is a 3D printer? How does it work? How did you achieve the 3D effect? I've been thinking, my curiosity has been driving me. Unconsciously, we came to the 3D printing hall. As soon as I entered the door, I saw several square machines coming into view. Look carefully, there are thousands of small parts in it, which looks very advanced! At this time, I saw a small octopus print and saw blue filaments winding around it again and again, like silkworms spinning silk. It works like this. Later, I visited some finished products, including double-decker villas, high heels, figures, and some small animals and gadgets. I admire: 3D printers are really amazing! Dad also promised to buy me one. I chose a pink rabbit, which is freshly made. I looked at it carefully-the lines printed layer by layer are clear, changeable and exquisite, and I can't put them down!
When I walked out of the Science and Technology Museum, I was amazed at the rapid development of science and technology and proud of people's ingenious creativity!

3D printing is a rapid prototyping technology, based on digital model files, using adhesive materials such as powder metal or plastic, and constructing objects by printing layer by layer. What I like is 3D printing with a 3D printing pen. This pen is made of corn stalk, which melts at high temperature and is used for 3D printing. Just like the pen in Ma Liang's hand, we can create wonderful works, which can be flat or three-dimensional, making people feel particularly fulfilled.
My first contact with 3D printing was in Zhengzhou Intangible Cultural Heritage Museum, where I saw many models made by 3D printing technology, including trains, planes, cars, bicycles, flowers, glasses, knives and vases. These models were beautifully made and caught my attention at once. So I can't wait to start the experience. My first work was a strawberry, which took about an hour to finish. At first, the lines I drew were not very smooth. There were always protrusions on them, and there were some filaments drawn out in some places. Although it doesn't look beautiful, I am still very happy.
Later, I made several 3D prints in the echo hall, and the level was improved again and again. Now I have made many things, including flatbed, deer, fans, three-dimensional trucks, planes and scorpions. The teacher also praised my work for its smooth lines. In the process of making, some three-dimensional graphics take two or three hours to complete, which can especially temper my will.
This is my favorite 3D printing. It can not only make me feel the joy of creation, but also cultivate my perseverance and patience, so I like 3D printing very much.
