Las impresoras 3D se han vuelto lo suficientemente asequibles para llegar a ser algo común o pensar en adquirir una, pero ¿deberías comprar una? Esto es lo que debes considerar sobre los materiales, los posibles usos, el software y mucho más, antes de sumergirte en ellas.
Hoy en día las puedes encontrar en minoristas como Best Buy y puedes comprar numerosas impresoras 3D y sus suministros en Amazon.com y en otros puntos de venta en línea. Aunque aún se encuentran principalmente en los talleres o en estudios de diseño, en escuelas y centros comunitarios, y en manos de aficionados, las impresoras 3D se encuentran cada vez más en espacios de trabajo, salas de recreación y cocinas, y quizás en una casa cerca de ti.
¿Cómo es el proceso?
En su forma más básica, la impresión 3D es un proceso de fabricación en el que el material se coloca, capa por capa, para formar un objeto tridimensional. (Esto se considera un proceso aditivo porque el objeto se construye desde cero, en lugar de procesos sustractivos en los que el material se corta, perfora, muele o mecaniza).
Al igual que las impresoras tradicionales, las impresoras 3D utilizan una variedad de tecnologías. El más conocido es el modelado por deposición fundida (FDM), también conocido como fabricación de filamentos fusionados (FFF). En él, un filamento, compuesto de acrilonitrilo butadieno estireno (ABS), ácido poliláctico (PLA) u otro termoplástico, se funde y se deposita a través de una boquilla de extrusión calentada en capas. Las primeras impresoras 3D que llegaron al mercado, fabricadas a mediados de la década de 1990 por Stratasys con la ayuda de IBM, utilizaron FDM (un término registrado por Stratasys)
Otra tecnología utilizada en la impresión 3D es la estereolitografía. En él, un láser UV se ilumina en una tina de fotopolímero sensible a los rayos ultravioleta, trazando el objeto que se creará en su superficie. El polímero se solidifica allí donde el haz lo toca, y el haz «imprime» el objeto capa por capa según las instrucciones en el archivo CAD o CAM desde el que está trabajando.
¿Qué programa se necesita?
Casi todas las impresoras 3D aceptan archivos en lo que se llama formato STL (llamado así por estereolitografía). Este tipo de archivos puede ser producido por la mayoría de los programas CAD, desde costosos paquetes comerciales como AutoCAD hasta productos de código abierto o gratuitos como Google SketchUp y Blender. Para aquellos que no están dispuestos a crear sus propios archivos 3D, las bases de datos de objetos 3D como Thingiverse de MakerBot ofrecen numerosos archivos de objetos 3D que se pueden descargar e imprimir.

Depart in the afternoon, and it is almost sunset in the inner city.The office is closed.Governor Did the governor come so fast this year The year of Gengzi is the year of the Jingcha.
Officer, Governor Zhang led a team into the mansion in the middle of the night and used weapons recklessly.If Emperor Yuan Jing was not a balance madman, Layman Ziyang might still be teaching and educating people in the academy.
When you see a secluded alley, you can go in boldly.Immediately, Huben Wei stepped forward, took out the shackles and put them on Yang Chuannan, and escorted him out of the mansion.
He formed a Yellow Banner Gang in Yuzhou to beg for life.Piano, chess, calligraphy, painting, poetry, poetry, and Fu are proficient in everything.

Zhang Xingying killed the Yunzhou rebellion in the cradle.Three This is not easy.Xu Qi an used a trumpet to pretend to be aggressive.
Otherwise, the enemy is in the dark, and I am in the light, so there is no trick.Don t the two adults find it strange that the bandits cut the trails, but let the valuable goods be scattered all over the place and ignored them.
Li Yuchun was unhappy when he heard it, and said in a deep voice Said Who says it can t be done, just watch and learn.Xu Qi an rolled his eyes.Congratulations, Guangxiao will get married soon.
Daoist Jin Lian sat cross legged on the bed, shook his head and said.Finally, he clasped his fists and raised them above his head, Grand Wei treats me with great kindness, and treats me preferentially everywhere.
Governor Zhang walked up the stairs to the second floor with his hands behind his back.The girl in a long skirt led her out.Her lips were puckered up immaturely, and she followed her steps reluctantly.
Wei said with emotion Who else is there besides him After a pause, he looked around at everyone, and said in a tone of sharing secrets This person s identity is extraordinary.As for No.5, No. 6 and No.9, each has its own characteristics, but in terms of perception, they are not as good as No.
The servant girl smiled, and said to herself, even if it is scum, it is really sweet when it is sweet.Susu grasped the point at once Ah, you are Governor Zhang s brother Otherwise, how could I have such a big voice So.
Song Tingfeng suddenly pointed at a certain place Siming Bridge People s eyes then fell on the position where his finger was pointing, where the outline of the arch bridge was outlined, and the sign in tiny characters Siming Bridge.Let me say something at this time Emperor Yuan Jing who suffered a thousand knives No.
His muttering sound entered the ears of several Yin Gong and Jiang Lvzhong without missing a word.Fuya What s wrong with the government office, I dare to kill people at the gate of the Ministry of Criminal Justice, is it difficult to kill you with a mere seventh rank experience Xu Qi an pressed his hand, and the sharp black gold long knife instantly cut the back of the experienced adult s neck, and the latter obviously felt the pain from the back of his neck, as well as his own warm blood flowing out.
Xu Qi an interjected Warlocks can also be ruled out.Zhou Min was also a tactic to delay the attack.That s all, turned around and wrote a secret report to shake things out.
Her little dissatisfaction with Xu Qi an gradually disappeared.In the room, Xu Sitting in front of the desk, Qi an gathered Qi with his fingers and scraped off a corner of the Spirit Sealing Talisman.
How do you know that I like Shenhou The image representative of harmony is like Xu Qi an, a constellation in his previous life, who found that the evil thoughts in his heart were about to move.Before we act, I remembered two trivial things and wanted to ask the Taoist priest for advice.
At this time Governor Zhang was only surrounded by Hubenwei and Jiang Lvzhong, and most of the watchmen stayed behind at the station.4 s reaction is too sharp, isn t it Xu Qi an swallowed, feeling the urge to be fleshed out soon.
Hearing that it was Wei Yuan s arrangement, the queen sighed, a little Resistingly scooped up a bowl of soup, frowning and savoring it.I am not her opponent.The prince coughed and came out To warm up the scene Huaiqing, don t be as knowledgeable as Lin an, you are a sister.
Hearing this, Xu Qi an suddenly realized that something was wrong.A large army of hundreds of people trekked in the wilderness, holding torches, moving forward silently.
Led by Jiang Luzhong, Song Tingfeng and other 20 gongs joined in the fun, happy to have fresh fish soup at noon.and retreated in fear.Leaving a part of the Huben Guards to guard the ships, Governor Zhang and Jiang Lvzhong led a mighty force and went straight to the Yuzhou Water Transport Office.
It feels like a young mature woman who is just 30 years old, and she also feels like a mature beautiful woman dripping with honey, or if you look carefully, you can still see the charm of pure love and coquettishness from her.
Hearing Jin Juan s words at this time, she couldn t help but chuckle, Then there s nothing you can do about it, just suffer.If the previous damage was 1, then today s damage is at least 5, and it s still a critical hit.
Although the city s maternal and child care department has not reached that level, if it wants to develop further, as Li Jianwei said, if there are no advantageous projects that can be taken advantage of, then don t even think about it.After saying that, he didn t care whether the old lady was leaving or not.
The action was very straightforward, and Feng Su was stunned for a moment.When the time is right, he can directly We have reached the capital.
Du Heng was in a daze for a moment, then he spread his arms and asked, How do you want to cooperate with your hospital Mei Dong was also sloppy and directly revealed the bottom line of their hospital, You can set any terms you want.However, the young woman didn t seem too determined, and was beaten and dragged by the old man and brought to Du Heng s side.
For the previous child, it took Du Heng about five minutes to get the child to cry, with sweat on his forehead.However, what is visible to the naked eye is that her overall mental state is very good.
Knowing that his actions at this time were inappropriate, he quickly stood up.Feeling terrible. Directly facing Wu Shengnan, he poured out all his bitterness, saying that he couldn t stand the charge , and how powerful the women in the work unit were.
The workers were all open. The cocoons were exposed.It is accumulated over a long period of time, so your kidney essence must be weak.
While I was shocked, my slow walk turned into a fast run.Director Zhang and Director Li looked a little regretful and wanted to leave.
The old man s eyes were full of confusion, Why is this the disease I m looking for I take a lot of Western medicine, and I often go for cupping, massage, and massage.Professor Zhang reached out to take the prescription, but he didn t even look at it.
He now understood why there were so few male doctors in gynecology.The situation is exactly the same as in the video. Dean Du can really cure this disease.
Therefore, taking pear paste also has the effect of moisturizing the intestines and laxative.What the host asked was very low level, just as hypocritical and ridiculous as an entertainment gossip reporter asking, XX, I heard that a movie starring you is going to be released, right These are all things that have been confirmed on the Internet.
There are handcuffs and mobile phones inside. Get it for me, quickly.The woman glanced around and said in a low voice, I wash it every day and change my underwear every day, but it never gets better, and it s even worse for a few days.
Du. Yes. Cao Binghe s mother followed her son s instructions and opened the bedside table.To sum up, the bigger the noise you make, the higher the heat, and the better the effect, the more violent the backlash you will receive, so violent that you can t even imagine it.
The title of the poem is disgusting, the shoulders are cold and sweaty, the lonely peak is stubborn, the minister is rough, the mother is lonely, abandoned, sleeping, powder, Feng Kai, smoke, pay for the diagnosis, so confused, dead, solitary, deep, thrown away, annoyed, so scared to chew the lonely bow, so Fairy.
Your answers will appear on the Internet as soon as possible.Darling, I must be so lucky. I heard that there are only two winners in the medical system this time, and these two are all his students.
Seeing that the dagger was about to pierce his face, Wu Shengnan used all his strength to tilt his body a little, and his head and the dagger barely missed each other.She wanted to make a fuss and beg, but she thought about her age, her work, and then she thought about it.
The progress is rapid and impressive. Wu Buwei suddenly laughed, and Yigulu rolled up from the recliner, No, this is what my dad and our director said, I m just paraphrasing it.Du Heng glanced at it and raised his eyebrows slightly, Half abalone frozen in sake, 11,800 for a portion.
That s right. Now that all your kidney yin and kidney yang have gone to other places, will your kidneys be empty If your kidneys are empty, will they not be able to work Once your kidneys stop working, you will be so dizzy that you can t stand up, and you will feel flustered.Wu Shengnan rolled his eyes angrily and pulled the quilt off his head.
It s better not to get it done. If you re hospitalized, it would be a waste to get it changed.I also looked at it in the morning and couldn t find the reason.
Based on his understanding of Du Heng, this is definitely not Du Heng s nonsense.Du Heng stood in the back and was thinking wildly, but the parents in front of him had already begun to shake their heads, No, we don t prepare such small toys for our children.
The navel is known as the Divine Palace, which is the place where the vitality of the human body gathers.Sister, tell me slowly, didn t our doctor treat you Yes, but he made a bad face.
Then he wrote a prescription in less than five seconds, and then handed it over with a smile.Otherwise, Liao Quansheng himself would not have the chance to sit face to face with Li Qin.
Do you think you are thirsty Auntie s eyes rolled. Then he asked, Doctor, what will happen if I don t care No matter what That would be a serious problem.
Prepare sedatives. He made a decision in an instant.If Li Jianwei really feels unhappy because of this matter and doesn t want to cooperate with him, then let him go.
The smell. At night, I opened the windows to let some air in and change the air in the house.But it is these minor problems that have been accumulated over the years.
He quickly waved his hand and said no and left. As soon as he left the ward, he received a call from Gong Daoyang.Now that you can develop with peace of mind, your dry mouth will be gone.
What is the purpose, and you already have two children, why are you planning to have another child A book chasing app recommended to me by an old book friend I have known for ten years, Mimi Reading It s so easy to use.When they first met, Du Heng felt that The old man was a bit old, and the mother looked like she was in her twenties.
Zhu Fanzhong, I Give me a suggestion and see if you can accept it.Nothing. The money they earn at the risk of being scolded may be your monthly salary, or less than your monthly salary.
I have something to do, let s talk after it s over.They don t like what I gave it to, right I have to find someone to judge it.
But Du Heng doesn t care whether you are happy or not.Wang Zhenzhen was also disgusted with people whose conscience was eaten by dogs.
Once the patient starts sweating and urinating, the dangerous period is really over.I have to know why. If you are planning to transfer to another hospital, we I won t stop you.
In addition to being sick in their bodies, these people are also sick in their minds.After all, they are their classmates. If something like that really happened, everyone s faces would not look good.
Zhou Yixian also responded proactively, Welcome Dr.Jin Zan said seriously, Dirty, I didn t expect you, Du Heng, to be such a dirty person.
But now, Du Heng once again said the diagnosis in the same tone, which made both of them feel indescribable excitement at the same time.The taste is slightly bitter and the smell is slightly fragrant.
Thank you, Dean Du. I feel much better. Especially my belly is not as bloated as before. I feel very relaxed.She pulled the eldest brother aside and pushed the wheelchair to stand in front of Du Heng s table.
It wasn t the first time Du Heng had seen Wang Juguo smoking, but every time he saw Wang Juguo smoking, he thought it was a unique skill.Once kidney yang declines, the evaporation power is weak and the qi transformation fails.
However, we are using the diagnostic results and treatment ideas of Western medicine to guide the use of traditional Chinese medicine.This was the first time Xue Yiwen looked at everyone so seriously since everyone entered.
You don t have to go anywhere. Just eat the food directly after your colleagues bring it.Even for the patient with gastroptosis, it can be said that the effect was immediate and the medicine cured the disease.
But this is not important. The top priority is still the immediate matter, how to renovate the red brick building and where the money will come from.Next to the patient was a woman in her 40s, who must be his wife.
If this ax is accidentally thrown out again, I may not be so lucky and have to dodge it again.After a moment of silence, Du Heng decisively clicked confirmation and received the patient s information.
Will Du Heng let them down of course not If the dialectic is clear and the patient s righteousness has not declined, there is room for maneuver for him.Then a thick smoke spurted out from his mouth and was inhaled by his nose, and then It spurted out from the mouth again.
It s up to you. Du Heng was a little dumbfounded. I seem to have forgotten that the initiative is in Dong Yuezhang s hands.It can be said to be the dirtiest place. Some people with limited mobility eat, drink, and defecate in the ward, and most of these people are elderly and suffering from various diseases sometimes the entire ward is filled with the sounds of coughing and spitting.
When he ran to the school gate, the anxious and panic look on his face was clear, Doctor, doctor, there are students going crazy inside.Wang Zhenzhen hurriedly took two steps, Why Du Heng opened the car door, invited Wang Zhenni to get in the car and asked, Tell me why you want it first, right I told you the last time I gave it to you, Don t take too much of this medicine.
If you had told me earlier, I would have reserved a position.With this temperature, no matter whether you are good at taking exams or not, you may doze off in the quiet classroom.
Let your girlfriend accompany you, go to the movies, go shopping, climb a mountain, and have a delicious meal.One million and two hundred thousand, haha, I will definitely not accept mediation.
it was a pity that both old men passed away from their injuries.His and the emergency doctor s responsibility is to treat illnesses.
Du Heng took a step forward, took a look at Xiaoying s condition, and then said very relaxedly, Okay, you can go to the examination room.It s hard to chat with this kind of person. He s not a big official, but he just likes to play riddles for you.
It is not a big cake at all, but a big cake with meat inside.
But after starting again, things were back on track.Okay. Maybe we will have to get some of Xiao Fang s glory in the future.
By visual inspection, she is 1. 7 meters tall, and even though she wears a little makeup, her beautiful face cannot be concealed.It was at this time that when the person who went to sort out the remains opened the lid of the coffin, he saw the person inside looking directly at him, and stretched out his hand to grab the corner of his clothes.
Free Is it free for you too The girl rolled her eyes and asked with a sweet smile, Auntie, was your medical treatment also free just now Yes.Thank you, Uncle Zuo. Zuo Liangliang stood up and walked out, You guys You two have a sip of tea, and your aunt will take you to the house to sleep for a while.
If you are diagnosed with emphysema, then you just can t smoke, catch cold, or do heavy work in the future.Du Heng and the others each use a set of needles for each person.
Du Heng is willing to teach, and he teaches very carefully.She asked lightly, What positions do these people have It s confirmed, Sanjiang will be here this week.
Jin Zan s wife hesitated for a moment, and then said to Jin Zan, Forget it.Did you really buy it from the mother s husband, not the doctor or someone else Sure, how could I lie That s good, that s good.
And Zhao Xinfang turned back to the sunny and cheerful young man, and he had already washed up.This year, we will vigorously develop primary care, with a large degree of tilt in terms of policies, funds, etc.
Wang Zhenzhen, on the other hand, was a little disappointed, but immediately smiled, It s good to be a doctor.The day before yesterday Du Heng s eyes lit up, What kind of medicine did you drink I don t know that.
People may not want to know him as a doctor at a health center.Several people entered the clinic humbly. After greetings, Zuo Liangliang also took out a brochure.
After all, although he is now pursuing the path of orthopedics, he really admires Du Heng s level of internal medicine.This caused a very eye catching phenomenon to appear on the streets of Jinzhou.
Unexpectedly, more than a month later, I really became the acting dean.First, when you push your child out, it s best to use a stroller with a sunshade.
He hesitated for several seconds before saying, Tiantu Be sure, can you hesitate to treat patients Du Heng said, and stabbed the needle in his hand steadily, Tiantu, specializes in treating asthma, cough and other diseases.It has been raining heavily outside, and there is water everywhere on the ground.
After returning home, I didn t pay attention to removing dampness, and secondly, I didn t pay attention to maintenance.But Du Heng actually doesn t recommend that everyone do this.
Don t use any unscrupulous methods, and don t take it for granted that you will treat it yourself.Later, Du Huang stopped studying in junior high school and went out to join the society.
I know, senior brother. Do you want me to pick you up on the mountain No, there s a van for people, I ll take it.She looked like a resentful woman and said, Dean Li, you come to judge.
After talking a lot, Li Qingde frowned when he heard this.
The leader pulled An Chunhui over to say something, and An Chunhui called Lao Song over again.Wei Kaida was scared. It s not that he didn t pay attention.
Thanks to the system. Du Heng felt a little disgusted as soon as the clich came out.After he finished speaking, he paused and said, Add Coptis chinensis and Pinellia ternata, quickly.
Of course, the fee is a little higher, 500 a day. If you want to apply, please contact this nurse Wang.Du Heng slowly stretched, took a breath and continued, We are doctors, and we should give the patient the most appropriate treatment.
After saying that, he hurried out, for fear that if he was slow, he would be beaten by this fool.sorry. Wu Buwei lowered his head and said sorry again.
Pain is a reaction of the pathogenic factors acting on the human body.Okay. After the words fell, Wu Buwei drove his car out of the side door.
Surging. No need to think about it, it must be the notification sound of salary arriving.Suspension and fines are enough to make this woman who loves money as much as her life miserable.
He must be in the hospital. Can you help me ask when Dr.When pain comes, if you can bear it, just bear it. If you can t bear it, just buy some painkillers and painkillers.
Her hair was meticulously combed with silver hair, but her eyebrows were dark, with a few long white eyebrows on the tips of her eyebrows, making her eyes look bright and bright.Uncle Zuo, I m so sorry. I rejected your proposal this morning.
This gave her face to Zhang Jinlian and Li Qingde. Otherwise, if the doctor he manages has such an accident, he, the leader, will definitely not get any benefits.
