Depth of the magic of the magic 3D printerStudent:Joey_ZhangStudent Number:GS1521269*Agenda3D Printer HistoryWhat is the 3D Printer3D Printer Basic principles and existing technologiesApplication of 3D printer 3D printing applications in life*3D Printer History 3D printing concept as early as a few decades ago has been proposed.In the 1970s,with the rise of 3D aided design,designers can see virtual 3D objects in computer software,but to these objects in clay,wood,or is made out of metal model is very difficult,can use time-consuming cost money to describe.3D printing,so that the plane into a three-dimensional process a lot simpler,designer of any changes can be in after a few hours or overnight to re print it out,rather than spend a few weeks time factory put the new model manufactured.Only in this way can greatly shorten the production cycle,reduce the production cost.And with the continuous progress of science and technology,more materials are printed out,it was discovered that the original can also be so play.The Economist magazine had commented:inventions can bring influence,at that age are difficult to predict,1750 steam engine so,1450 printing so,transistors in 1950,too.Now,we still can not predict,3D printing will be in a long time how to change the world.*What is the 3D printer 3D printer,a machine which is a kind of rapid prototyping technology,it is a kind of digital model file,the use of powdered metal or plastic and other materials can be bonded by layer by layer to construct the object technology.In the past,it was used in mold manufacturing,industrial design and other fields.It is now being used in direct manufacturing of some products,which means that this technology is becoming popular.The upper part of the machine is a translucent cover,a row of the control button next to a computer.A cover,left standing four boxes of different colors of ink,on the right side of the work area put gypsum fine grinding powder.The work,the powder will be a layer of liquid connection is also a special glue,in accordance with the different cross sectional pattern curing,one layer upon layer,feel like a cake to create three-dimensional entity.*3D Printer Basic principles and existing technologiesIn fact,3D printer principle is very simple,each layer of printing process is divided into two steps,the first in the need to spray a layer of special area of glue,glue droplet itself is very small,and not easy to spread.Then it is sprayed with a layer of uniform powder,the powder encountered the glue will quickly cured bonding,while the region is still loose without glue.In this way,the solid model will be printed and formed with a layer of glue layer of powder.After the completion,to deal with the powder around the items covered with powder,which can be recycled,and then coated with the hardness of the glue.Now there are two types of 3D printers,one is the stacking method,one is sintering.Principle is basically a multi-layer printing,and stacking and sintering is only the difference between the molding technology.Stack only molding plastics,such as silicon material,the curing reaction rate requirements,and the sintering can using laser heat treatment metal material things out of metal powder,the entity may through grinding,drilling,plating way for further processing.So 3D printers and ordinary printers,the biggest difference is that ink.*3D Printer Basic principles and existing technologiesExisting 3D printing technology to achieve 600 DPI,the thickness of each layer of only 0.01 mm,want to perfect show hair is still very difficult,but to do small parts,model enough and to spare.The development of technology and the powder is very good,the material is thinner,each layer is thinner,the higher the accuracy of the things done*Application of 3D printer Medical industry:Recently,a 83 year old man suffering from chronic bone infection,so replaced by the 3D printer,print out of the jaw bone,which is the worlds first use of 3D printing products to do the human skeleton case.With the development of technology,and even can be printed out with the activity of the human body tissue.scientific research:The fossils to 3D scanning by researchers at Drexel University,Philadelphia,PA,USA,using 3D printing technology to make the 3D model for research,not only retained the original fossil all the external characteristics of,and scaling,is more suitable for the research.*Application of 3D printer Product model:For example,Microsofts 3D model printing shop,after the product design,through the 3D printer to print out the model,the design and manufacture department to better improve products,to create a better product.Architectural design:In the construction industry,engineers and designers have accepted the use of 3D printers to print the architectural model,this method is fast,low cost,environmental protection,while making exquisite.Fully meet the requirements of the designers,but also can save a lot of material.*Application of 3D printer Manufacturing industry:Manufacturing also requires a lot of 3D printing products,because 3D printing,both in cost,speed and accuracy than the traditional manufacturing much better.3D printing technology itself is very suitable for mass production,so the manufacturing industry using 3D technology can bring a lot of benefits,and even the quality control is no longer a problem.Food industry:Yes,is the print food.Researchers have started to try to print the chocolate.Perhaps in the near future,a lot of food that looks exactly the same is to use food 3D printers print out of the.Of course,the food that may be produced at that time will be much more expensive.*Application of 3D printer Automobile manufacturing industry:It is not that your car is a 3D printer to print out the(of course,maybe one day this possible),but that the automotive industry in safety testing,substituting some non critical components with 3D printing products,in the pursuit of efficiency while reducing costs.Jewelry/Arts&Crafts:This is one of the most extensive market.In the future regardless of your personality pen,there are still your body for the relief of the mobile phone shell or is with you and your lover in the world unique ring,may is a 3D printer.Dont even wait for the future.*3D printing applications in life 3D printer now,in Europe and the United States has become a trend for geeks and gimmicks,and high-end customer service.Like New York,another use of 3D technology to produce consumer goods company quirky has 20 million registered users,they online to collect the users ideas,product design drawings,with a 3D printer to the fastest speed molding,designers often from a creative won many income,some users a year can earn tens of thousands of dollars.And Californias legacy in the company,using objet 3D printer making 3D model and prototype for fragments of film special effects,for actors to tailor can perfectly suited to the actors face,neck and head props,in the movie Jurassic Park,Avatar,Iron Man and the Avengers are applied.A Japanese company has even launched a for individuals baby recovery services,only need to deliver the baby in the mothers belly X-ray photos,they can recover the 3D image,print out a belly baby model as a souvenir.。*3D printing applications in life The 3D printing has yet to be universal,on the one hand is used in industries in the high-end models into larger,industry investors more cautious,in a wait state,on the other hand,the universal application of is from the recently begun,lack of user have a deep understanding of 3D printing,due to some news on the description using exaggeration,bold prediction,so give people the feeling is the plot of the movie.*3D printing applications in life Insiders,compared with the United States,Chinas lack of DIY and creative design habits,so the 3D printers greatest advantage is often not play,to become the mainstream of manufacturing technology also needs 3-5 years.In addition,foreign 3D printer price is too high,and some restrictions on the export of,domestic 3D printers in the precision,speed and print size cannot meet the needs of commercial,in geometry optimization,depicting the textures and materials,cutting and hollow parts do the printing preparation,support arbitrary 3D software to generate the data and of mega model automatic segmentation aspects need further improvement.However,with the upgrading of the heat,the blue ocean will soon be found,to solve only a matter of time.*Thanks!*
