3D printers are devices that you can use them to make real 3D samples from your pictures in the computer. Their technologies let you use the composite material to print your deigns.
3D printers have a good precision and their technology is progressing fast. Today, 3D printing is not only a hobby for general users, but also in some profession like medical applications and industrial modeling has been used improvingly. It seems that in the near future, the main users of this technology become from progressing countries. Because, the loss of some resources and tools make them using 3D printers.
Raprap has been introduces the first generation of home usage 3D printers. In these printers, melting rubber is used to produce the products. There have been introduced several industrial 3D printers with capability of printing using metal, liquid resins, ceramic dough and even food materials. It has been passed less than 1 decade from the introducing laser printers instead of needle printers. During this time, the users of laser printers have been satisfied with them, but no one guessed that in less than 10 years, some printers will be produces that are not comparable with laser printers.
Form now on, every 3D design in your computer can be produced in real world in less that a few hours. 3D printers are known as particle or layer printers, since the principal of their functionality is that our product will be formed by accumulation of layers on each other literally. The main superiority of this product upon the conventional methods is that the work speed and precision here is higher and the primary substance wasting is too lower .
For now, many industries are using these printers, but their scale is so small. Because of their difficulties in control and working with them, 3D printers are using in manufacturing first prototypes of the products and are hardly used in the product lines of the factories. Today, there has been produced some home usage models of 3D printers. Just think that what great work you can do by these printers! From now on, instead of online shopping of many devices, you can make them with your favorite changes in your room and enjoy from your creation and novelty.
Some samples of 3D printer productions:
Printers are tools for printing information and pictures on a sheet. They can be colored and laser type or needle and older type. However, 3D printers can make 3D shapes from your pictures using a composite. Nowadays, 3D printers are progressively used for home and industrial applications and are expensive too. At the CES2014 exhibition, several types of 3D printers introduced to people. These are using several materials to work and has the ability to manufacture with greater speed and quantities. .
At first, they were used to make some 3D samples of different tools. These can help people to make more complicate designs in more realistic shapes just look like the prototypes. To make the first samples of tools, it is needed to produce a 3D file of designing the tool. The printer will receive that file and begin to accumulate layers in multiple steps to complete the design.
3D printers can print vertically in addition to building shapes on a plane with length and width. Consider for example that the printer ink has a diameter of 0.01 millimeter and you want to make a 3D cube. The printer will begin to print a square with dimension of 1*1 centimeter and thickness of 0.01 millimeter.
After this step, the printer nozzles that distribute the ink move to up and create another layer on this layer. This happens again and again until you can get a 3D cube. The only difference of 3D printers is that they can use materials like rubber and resin to make shapes and the width of layers are actually greater that 0.01 millimeter, that is about 0.1 millimeter that seems an ideal one. The speed of making layers, layer width and the usage material in 3D printing are important factors in the quality and precision of the resulted products.
About the differences of 3D printers working method in comparison to CNC devices, it should be mentioned that 3D printers work using melted materials but the CNC devices work by cutting and separating different parts of a product to create the final product.
From now on, instead of online shopping of many devices, you can make them with your favorite changes in your room and enjoy from your creation and novelty.
Actually, you should learn about controlling both devices enough. Otherwise, they can’t be used simply. The 3D printers applicability is different according to the materials they use. They use rubber, nylon, metal or other flowing materials that are used due to the request for the resulting product. As we said prior, they build shapes by injecting the initial materials layer by layer. These layers become sticky together and after a short while, our product will be ready.
The real value of 3D printers are evaluated both economically and innovation based. From economic viewpoint, the 3D printers open new sights to the community and using them, the speed and variety of manufactured products along with their qualities improve. It can create, thousands of job opportunities in the nations.
Nowadays, 3D modeling is common in several fields like plotting, architecture, industrial designing, robotics, aerospace industries, etc. these models before now, were 2D pictures on the screens or sheets to give a feeling from the idea of the designer to the people. The 3D printer technology began with using in military industries. After that, it was expanded to other fields. It is often used in applications that the complexity of the part is high or it is needed to an initial prototype for modeling.
1. Military industries :
Military industries are accurate and complexity in tools and devices. Often, there is no financial limitation, too. These make 3D printing one of the most important and substantial devices of military research and manufacturing centers.
2. Aerospace industries :
These industries need small precise objects. So, they use 3D printers in creating objects that there is no possibility to create them using other devices. The people who are settled in space stations, often need some new parts for experiments or repairing work. This can be achieved using 3D printers simply. Another interesting fact is that big space companies in the world intend to build their station in the moon using 3D printers. This great project is being accomplished in the research group of NASA under the supervision of an Iranian manager beside other managers.
3. Jewelry :
Delicate and precise modeling is an important factor in jewelry industries. Using 3D printers, the jewelry industry has been improved very much recently. There is a professional article about 3D printer application in this industry in our website.
4. Architecture :
The structure designers are interested in create a real model of their designs. This can be achieved by 3D printers. The designers of exhibitions, interior designers and constructors of residential and business complexes will have a special advantage by using these printers.
5. Animation :
The designers of cartoon characters are interested in modeling their drawings. For these professions, iran3d-fdm/250 3D printers are suggested.
6. Automobile :
The automobile industry needs complex modeling. The 3D designed parts should be prototyping for several times and using 3D printers make this simpler.
7. Medical applications:
The body organs are different for any person. Using 3D printers, the body skeleton will be designed and modeled proportionate to each organ. This application of 3D printers needs a high precision.
8. Shoes industry :
In this industry, designing is so significant. The shoe designers test a sample several times to choose an appropriate one for mass production.
9. Educational :
Universities and research centers have an urgent need to 3D printers. iran3d is ready to cooperate with these organizations.
10. Homemade applications :
It is anticipated that 3D printers will be common soon in every profession. All the professions that need parts need to create a sample test at once and begin to mass production after that. In near future, with decreasing in 3D printer prices, the homemade applications of this product will begin. iran3d manufacturing has the necessary basis to be pioneer in this technology.
- Preparation process
When you click on the 3D Print button, it begins to create a premanufacturing process. The internal air of the device will be warmed to begin the process. Simultaneously, the production chamber will be full of the powder.in this stage, it is possible that the alignment of printer head for reading the pattern happens by an electronic eye.
–- Print process When the premanufacturing step has been done, printer will begin to print the created layers of its software. The device pushes the powder from the sections to the production chamber. The cartridge is moving in the primary layer and creates the first pattern sending by the software with the agglutinate. The agglutinate transforms the powder particles to solid and keeps the rest for recycling. Then the underneath piston, reduces the basin of powder production chamber to be prepared for the next layer. This cycle continues until the time that model will be completed.
– - Recycling and elimination of additional powder: The model is prepared for the optimization. The device will automatically send the peripheral powder with vacuum pressure and repeated shaking to the end of production chamber. This additional powder will be send to hopper section after filtering for reusing. After that, the device will be open and the model will be sent to powder elimination chamber. At this time, the user can use compressed air spray to eliminate the rest of powder from the final model. When the user clicks the 3D Print button, the internal atmosphere will be warmed and the head will return to its specific position.
- Printer begins to work with a layer of powder.
- The cartridge is moving in the primary layer and creates the first pattern sending by the software with the agglutinate.
- Then the underneath piston, reduces the basin of powder production chamber to be prepared for the next layer.
- Cycle continues until the time that model will be completed.
- Additional powder will be send to hopper section after filtering for reusing.
- The agglutinate transforms the powder particles to solid and keeps the rest for recycling.
- • The cavities will be filled and a more optimize model will be produced.
- Building 10 houses in 1 day using 3D printer:
This is a dream to build a house in 1 day or 1 week. But a Chinese company could make 10 buildings using the advanced technology of 3D printers in 24 hours. This is a huge achievement in building industry. The material used for this project are mostly from recycled material and the approximate cost for each building is about 5 thousand dollars. This technology could be effective in housing crisis elimination in populous countries. In addition to increase in manufacturing speed, the other advantage of this technology is the reduced cost and increased efficiency. They can use cement, glass or other material in addition to recycled material. In their manufacture, the diagonal printing technology has been used that is beneficial in houses isolation.
- Printing artificial organ:
The medical researchers ang engineers of Cornell university, have produced an artificial ear that is just similar to a natural one using 3D printing technology. This product has been manufactured to help child that have congenital problem in this organ. This prosthesis is the production of a multi-step procedure and can be substituted the old artificial products that had a Stairofoam like fiber. Also it can be substituted cartilage removal system of patient chest, as a little trouble method. For this production, they make a 3D model of patient ear at first. For this aim, they scan a healthy ear sample of child. After mirroring procedure, they could gain the model of the other ear. After that, they use 3D printers to make a mold with the precise shape of ear. After that, they filled the mold with a Collagen Jell-O material with high density.
After the printing procedure, they inject the cartilage cells in to the Collagen Jell-O material. They used caw cartilage cells for this aim. But maybe they will use the cartilage cells of the patient body in near future. After 1 or 2 days, the cartilage cells begin to duplicate and substitute the Collagen Jell-O material. Now, the ear can be implanted to body and covered by the skin to cartilage cells seem more natural.
The biggest advantage of this method over previous ones is that the production method can be custom-made. It is hoping that the production will be improve more and more. The improvements include finding a method to use Collagen Jell-O material as the ink of 3D printers without needing to plastic mold. The researches hope that implant this prosthesis to human body in coming year. The Naj Robotics research center, is capable to produce various robotic arms, rehabilitation devices and design and manufacturing various industrial parts using 3D printing technology. You need to just give your order to us!
The 3D printing procedure is automatic, so every beginner person can work with these printers. Although, somethings happen through printing that user is unaware of that.
1. The output file with 3D printable format will be delivered to user. The output software design CAD file is a network of lines that encloses a 3D volume. 2. The 3D printer software, transforms the output to thousands of digital layers. Each of these layers will be printed as the output later. 3. Each layer is printed on another layer and this continues until the final model comes to the real world. /p>
2. Cartridge fixing plat: transforms the powder particles to solid state.
3. Production chamber: the area that different components are manufactured inside that.
4. Cartridge: the place of printer heads.
5. Compressor: produces the compressed air to complete building the components.
6. Residue filter: prevents entering the other solids to the next stage in order to form a better production.
7. Electronic box: a computer board that controls the whole printing procedure.
8. Gantry: a horizontal band that moves forward and backward throughout the layers.
9. Hopper: contains the powder that the models are created from.
10. Reservoir: collects the fixer from cartridge and puts the fixing resources under the gantry.
11. Service station: cleans the printing heads automatically whenever it is needed.
12. Vacuum valves: manages the process of powder collecting from the production chamber.
For now, the main problem that seems to be a trouble in future is the existence of fake devices in market. If these devices become prevalent and regarding the fact that making products using these fake devices would not appear significantly different from the original printers products, the great companies in this industry will be damaged a lot. If the main companies will be bankrupt because of this matter, in addition to economic losses, we will witness of a huge rate of unemployment of their workers. Even recently, some fake products of Van Gogh’s painting have been observed from these fake devices!
Put all the mentioned problems aside. Imagine the harm of using a glass that is maid by fake material for your eyes. This would be catastrophic. For these reasons, the big companies prefer to keep these industry limited in order to prevent some fake companies entering that with their fake and health harmful products. Also, the help of governments with establishing regulations in this regard seems mandatory.
At the moment, in order to be familiar to different kinds of 3D printers there are much information in various websites. But, there are not enough information explaining their working method. If you need to know more about it, you can see MIT university website. It would be so helpful!
the 3D printers will soon be common among general users and as the other old 2D printers will be used in homemade applications. For now, that the market of this product is not so competitive, it is a good opportunity for new researchers of all countries including Iran to find a good place in the global market. Albeit, a Chinese company is producing a similar 3D printer to Iranian products that has a smaller size and higher price.
However, as they have said, it is only the price of technology and not the device parts prices. Iranian company in the other hand says that, they intend to produce a printer with high capabilities and lower price at first and in the next step, after commercializing it, they will define proper after sale services for this product.
It is almost a long time that 3D printer has been transformed to a hot subject to most users and companies and we are the witness of its progression. However, a problem against this new technology is the high cost of 3D printers. Now, the cheapest model in the market that its name is MakerBot Replicator has a price of more than 2000 USD and some kinds of 3D printers cost up to 15000 USD.
Recently, the former executive manager of MakerBot has been established a new company named as Solidoodle that presents its first 3D printer with the price of only 499 USD. This printer accomplishes the common duties of other 3D printers and give you the possibility of printing objects with the maximum size of 15*15 cm. Now, you can go to Solidoodle website and buy one of the interesting cheap printers of this company.
