Automation technology of creation three-dimensional model of any physical objects by means of prototyping machines like stereo lithography apparatuses, SLS systems (selective laser sintering) or three-dimensional printing is called rapid prototyping or RP. Being the part of rapid production tooling, the process of rapid prototyping is assisted by a computer that is why it is also called CAD manufacturing. Rapid prototyping can divided into several types, or methods. The first method called additive is based on the layered technology. Any CAD graphical program creates an image of a future object and divides it into cross sections, being cut off gradually during the prototyping process. A prototyping machine casts an object from such materials as metal powder, prototyping wax, different prototyping liquids, etc., the same way as the object is segmented by a computer – layer by layer. Layers are joined by means of glue usage, shaping the exact copy of the virtual prototyping model. This RP process looks the same as ancient ceramic mold casting. One of the greatest advantages of rapid prototyping is that an object of practically any geometrical form can be produced. The only minus characterizing RP is that produced parts can be sometimes smaller than actual parts or details of mechanisms.
The second RP method is a subtractive one. The essence of the process lies in following. The RP machine uses special tool not to build up but to cut off the layers of materials, such as prototyping wax, in order to create the exact copy of the source object. CNC or computer numerical control is similar to this RP method. Subtractive technology is much more reliable and tried than any other rapid prototyping technology. It has much in common with sculpture, where extra material is usually carved off by means of special tools in order to get forms that are more accurate. Considering disadvantages of subtractive method, it is necessary to admit that this method is usually applied for creation of simple details. This method is great for big-scale projects, but taking into account that subtractive method is good for production of small parts, details must be combined to get the accomplished product.
Combining of materials is very important in the rapid prototyping technology. Mixing is usually done to get more solid and reliable model. For example, the outer shell of the model may consist of some soft prototyping material melting at high temperatures, whereas the inner filling is done from temperature resistant material. When a model is subjected to heat treatment the outer layer melts and the finished model has accurate shape and incredible solidness.
Here are machines including either both mentioned technologies, or one of them, making it possible to create prototyping models fast and qualitative.

Since the second half of the 20th century, computers have made several steps forward on the way of improvement and development. Nowadays any branch of economy, any industry, business or corporation cannot do without computers. Every company has a system administrator in its staff, while the breakdown of even a single computer can stop the whole production, which is inadmissible, especially when it comes to companies, working with foreign clients and having to connect with them by means of computer network. Special software programs are created for different companies and with different purposes. Accountants, hotel receptions, stocks, economic enterprises, police departments, courts cannot work without special software containing all necessary numerical data. Such business organization helps to avoid failures in working procedure, to have all needed data ordered and to serve every client in a proper way.
Services sector is hard to imagine without computerization. Reservation software is used in most big and small restaurants, hotels, motels, inns, etc. It helps maintenance staff to serve clients, to provide them with accommodation. Unfortunately, those establishments, which do not use such software or save money, get less from this business as their services are of lower quality comparing to those restaurants and hotels, which do use such computer programs.
Have you ever visited big restaurants? There are plenty of tables belonging to different sections. These sections are served by different waiters and waitresses. An administrator can immediately tell you which table you can take. Have you ever thought how much time it would take for this administrator to find out which table is not occupied, if the restaurant is supposedly divided into several rooms? It would be very uncomfortable for clients to wait for so long. Special software hastens this process, so that an administrator just has to check the information in his or her computer.
Creation of these software programs would be impossible if it was not for rapid prototyping. Firstly rapid prototyping was obviously used for designing of computers and its parts. The testing of computer parts would be impossible without RP and if it was done manually, as it was in the second half of 20th century, the computer progress wouldn’t be so swift. It took much time for the best computational scientists to create so powerful and enhanced machine as they were in the late 1990s, not to mention present time, the time when more and more powerful computers are released in the market every day. The process of software design is also very time-consuming and difficult process, carried out by the greatest programmers from all over the world.
According to evidences we have just received, all branches of all spheres depend on rapid prototyping, one of the great innovation of the 20th century.

Rapid Prototyping And Three-Dimensional Printing

freetraffic — Fri, 04 Dec 2009 16:45:14 +0000

Rapid prototyping and three-dimensional printing became an important part of prototyping, making the process more enhanced and fast. Since that time, it has been available only for powerful industries, corporations and companies due to its high price and expensive equipment. Presently, the time is coming when rapid prototyping technology and 3D printing is going to become available not only for big industries, but also for private individuals and small industries that may need to use rapid prototyping for their own purposes.
The process of three-dimensional printing is similar to the usual printing. The only difference here is that different materials like plastic are used instead of ink, and the process does not need paper to fulfill a project. Let us imagine the following situation. It is snowing outside and the temperature is very low. You have a great coat, protecting you from bad weather conditions and you are just going to put it on when you notice that it lacks one button. You have nothing else to get on and you have no extra button to sew on the coat. Just imagine how convenient it would be, if you had a device capable of producing the same button in few minutes! Three-dimensional printing would come in handy in such situation. So what is the essence of the 3D printer work? The process is assisted by a computer, by so-called CAD technology (computer-aided design) which sends a signal to a printer, producing the needed detail, part of any real object. The production is carried out using layered technology, which is the growing of material layer-by-layer until the model is done to its full size and considering all needed characteristics.
One of possible applications of three-dimensional printing technology is production of toys and their parts. It is very interesting variant, because you will not have to buy a present for you little niece or a child of your friend – you can produce it yourself with the help of three-dimensional printing. All you need to do is to buy or download the software for a toy you want to make and to install it on your computer. The further process is carried out by a computer and 3D printer without your assistance. The created toy will be a unique one produced from the heart. Just buy a gift-wrapping and greeting card and it will be definitely the best present ever.
If you have children, you probably have many broken toys scattered all over the house. These toys are abandoned and now you can easily repair them by producing missing part with 3D printer. So, 3D printers are going to become the beginning of the new era in modern technologies letting people produce lots of thing by themselves without resorting to somebody’s assistance.

Rapid Prototyping Technology: Short Review

freetraffic — Fri, 04 Dec 2009 16:15:13 +0000

Rapid prototyping proved to be a great technological decision, which helps to create qualitative prototyping models in very short terms. The time is coming when rapid prototyping will be applied in order to satisfy the demand of the most fastidious clients who want to get the needed details in short term. Rapid prototyping provides the speedy production of the most complicated orders, which is one of the greatest advantages of this technology.
The application of rapid prototyping is restricted by its limited popularity and narrow specialization of the technology. The sphere of rapid prototyping usage must be widened in order to make this branch of prototyping more popular and salable.
Does rapid prototyping have a distinct definition? Well, different specialists describe this process in their own ways. Let us try to compose our own definition. Rapid prototyping is a computer-aided process, lying in application of additive technology in order to create a prototyping model (part, detail) of any real object. That is why some specialists say that they use CAD (computer-aided or assisted design) in the RP (abbreviation for rapid prototyping).
What was RP a couple of decades ago? It was a manual process that could take up to several weeks of painstaking work to produce the final object. It can be easily explained by the way the work was carried out. Prototyping specialists had to cast and shape the model manually, which is not that easy and very time-consuming. It was very hard to achieve the full likeness of the source painted model and final object. To get a perfect similarity RP specialists had to work very hard and about several days or even weeks. The process was gradually developing opening up new possibilities for rapid prototyping improvement. It took much time for rapid prototyping to become known among wide range of people, having nothing in common with engineering. Presently, the RP process is becoming more and more popular each day, and this fact can be corroborated by advertisement and great results of the process. As the process was so long-lasting, engineers began to think of how to make working conditions better and simpler. The manual work proved to be unproductive and unprofitable, so it was decided to create rapid prototyping machine that would be able to create any real objects and details of any existing mechanism. That was how the transition from manual prototyping to machine prototyping was made. The process became much more profitable, faster and qualitative. People all over the world continue to get the information about rapid prototyping, the branch offices of leading rapid prototyping companies appear all over the world offering their services. The RP became so popular that appearance of portable prototyping machines is round the corner. Who knows what surprises RP will give us!

Rapid Prototyping Process

freetraffic — Sun, 29 Nov 2009 08:00:10 +0000

Rapid prototyping is a brand new technology in creation of three-dimensional models of the ordered product. Less than 20 years ago rapid prototyping was just a project , the technology of the future whereas today it is a reality and very enhanced reality. In the past all prototyping models were created manually, the process was time-consuming and expensive. That is why specialists in the sphere of prototyping admitted the necessity to implement something new inexperienced before. It was not an experiment but glaring necessity because the obsolescence of the former technology became more and more obvious. As we can see, rapid prototyping technology came instead of old-fashioned unproductive technology that had to be replaced. RP (the shortened name of the technology, used more often than the full variant) became a starting point in production of the artificial copies of any existing object irrespectively of its size and shape, the production, called rapid prototyping. What is the essence of this new process? RP is a machine prototyping, carried out without human’s assistance. The process is computerized, so everything, needed to be done is to program a special application operating rapid prototyping machine. Three-dimension graphical program forms a potential model that is later done by means of machine prototyping. The system of computerized creation of the rapid prototyping is called CAD – computer-aided design. The CAD is an inalienable constituent of the rapid prototyping process. A finished model is usually extremely accurate and well shaped. What does help to reach so good results? The thing is, that design of the future model is fulfilled by high-accuracy 3D graphic program, which was specially created in order to work out models of the best quality. The technology does not need additional tooling to shape the result of the rapid prototyping process; a special layered technology was created exactly with this purpose. A computer transmits signals to machine; more precisely, CAD lies in programmed controlling of the rapid prototyping machine work.
The process itself is not as rapid as it may seem from the name of the RP technology. Depending on the needed accuracy and requirements of a client, RP process can take from several hours to several days or even weeks of work. The main reason for this is that models under production can later be aggressively tested, depending on the sphere of model usage. In this case, two or more prototypes may be needed in the course of the process. Thus, the process can require even more time than it was predicted before the beginning of the project.
To sum up, rapid prototyping technology is a great step forward in prototyping sphere, which not only makes the whole process work faster but also provides qualitative and solid RP models.

Do You Know Enough About Machine Prototyping?

freetraffic — Sun, 29 Nov 2009 02:30:06 +0000

RP technologies include an important innovation called machining. Different small parts, constituents of modern technical appliances like digital cameras, camcorders, mobile phones and compact personal computers, musical players , printing machines, communication storage stations and etc are produced making these devices more enhanced and developed. One of the most obvious advantages of the machine prototyping is a volume of production, which is relatively big comparing to manual production. Machine prototyping is a step to the improving of the prototyping technology, which can become not just a developing industrial process but also a rapidly developing one.
Rapid machine prototyping can gain the results, which would be impossible if it was about manual prototyping process. What is rapid prototyping aimed at? First of all, it facilitates the labor conditions of people working in this sphere. As you understand, manual prototyping is not just an old-fashioned technology that was abolished because of its backwardness and lack of improvements, it is a very severe and difficult technology, using human’s resources for the achieving of best results. The results of manual work are not impressive and even pathetic, taking into account terms of model production offered by manual prototyping. On the one hand, nothing can replace something that is done manually, while it is handicraft that has always been valued, but on the other hand, using of manual work in prototyping increases the cost price of a model, which is unprofitable for both a seller and a buyer. Machine prototyping offers rational decision of the problem making it possible to reduce the cost price of the product , to enhance prototyping production and to increase producing capacity.
Rapid prototyping technology was given a number of alternative names; one of such names is layered production. What is implied under this name? The essence of the rapid prototyping production is building up of a real-size model of an object by growing thin layers of prototyping material. The whole process is fulfilled mechanically without human assistance. It hastens the process and gives better result. When a model comes of the machine it doesn’t require any additional tooling which also decreases costs of the production. The process is only controlled by a computer and machine, no outer interference. The process implemented by a prototyping machine is computer-assisted. It is called computer-aided design, or simply CAD, which is nothing but a complicated name of the computer program, controlling the prototyping process.
The process would surely be impossible without prototyping materials used for casting of a model. The materials used can vary from prototyping powder or liquid to prototyping wax and non-metal materials (metal materials can also be used). Models can also be casted of plastic. If a client needs a solid prototyping model aimed at aggressive testing, designers will chose an appropriate mix of materials.
All in all, rapid prototyping is meant for satisfying clients’ demands, so that both producer and customer get what they really need for relatively low price.

General Info To Be Aware Of About Rapid Prototyping

freetraffic — Sat, 28 Nov 2009 15:45:23 +0000

Rapid prototyping has several names, known to those who work in this sphere and who uses rapid prototyping services. Solid freeform fabrication is one of such names. The rapid prototyping technology, also called RP, is a new step in the prototyping industry, one more innovation in prototyping engineering. Rapid prototyping is creation of three-dimensional prototyping objects, requiring no extra tooling. In other words, RP designers and producer have no need to process the finished object with the help of tools and instruments. One more name for rapid prototyping technology is a layered modeling, which has appeared in the middle 80s of the 20th century. It is not only a relatively young technology, but also a revolutionary one. It lets designers working on the prototyping model put on the prototyping materials in a layered manner, so that the objects acquires a finished and ideal shape. This technology is also perfect because no extra work like curving and cutting off the extra material needed when the object comes from the prototyping table. Using rapid prototyping technology, designers are not limited by a small number of opportunities. Certain freedom of creative activity must be given to designers in the process of prototyping design. It is very important for any profession and rapid prototyping is not an exception. Another positive side in rapid prototyping is the speed of project implementation. Due to the computer-aided technology, rapid prototyping makes it possible to speed up the production up to several hours. What does make rapid prototyping so great in usage and help to get rid of tooling? Firstly, materials are of great importance. Modern industries offer a large number of RP material options. Of course, their price level as well as quality is different. One of the most usable materials is rapid prototyping wax. It combines both acceptable price and good quality. The material is very flexible, which helps to create the most accurate prototyping models without additional manual tooling. Rapid prototyping wax can be easily mixed with any other rapid prototyping material irrespectively of their quality and consistence. Mixing of materials is very important and sometimes inevitable, because it can be needed in order to get the model of the highest quality and solidity. The range of materials that can be added to rapid prototyping wax during the process is practically endless; you can even use rapid prototyping wax together with metal prototyping materials. RP wax is very good for casting of the shell mold, because it is hardening faster than any other material. It means that comparing to other material, rapid prototyping wax will let you maximally shorten the term of the rapid prototyping process. To cut the long story short, nowadays, rapid prototyping wax is one of the leaders in the market of the rapid prototyping materials.

The Stages Of Rapid Prototyping Technology

freetraffic — Sat, 28 Nov 2009 14:45:03 +0000

Rapid prototyping technology is used in a great number of industries, starting from medicine and ending in machine engineering. It is the creation of a real shaped three-dimensional prototyping model of this or that merchandize that is going to be released to the market. The process of rapid prototyping is a very important one, as it helps to carry out a kind of a social pole, concerning the potential popularity of the product in the market. The process also helps to find out all possible pluses and minuses of the future product, which helps to shorten the number of defective goods in production.
The RP process is multistage. The first stage of the process is the creation of the drawing or a sketch of the product under rapid prototyping modeling. This stage is usually carried out on paper, drawing board or a whatman paper. Special equipment is used to project an image onto a multimedia screen. The designers and producers of the product usually discuss the project before its approving. Such programs are used in medicine to project the model of a skull or a face when it comes to a plastic surgery, for example. A desirable effect is shown on a special screen, including all surgery stages. The computer programs used with this purpose are nothing more than three-dimension graphical applications capable of creating 3D model of any real object. These programs help to avoid risky situations possible during operations.
The second stage is numerical processing of the sketched information. Painted models of future rapid prototypes are processed by computers creating 3D models, which are later used as a basis for the actual prototyping process.
The next and the last stage of rapid prototyping is the machine prototyping. This process is very unusual and deserves to be described. To begin with, the process of machine prototyping could be impossible without CAD – computer aided designed which has been already shortly described above. The thing is, the special graphical computer program is capable of dividing a prototyping model into multitude of segments. This process is called cross sectioning. The segments are virtually cut off, layer by layer, until the model is not totally diminished. The prototyping machine, receiving signals from a computer, does an identical process but vice versa – the layers being cut off by a computer turn into the real layers building up a real prototyping model. Thus, prototyping technology uses no additional methods like tooling to create a finished model. All needed forms and details are made by a computer, which is one of the many RP advantages.
To sum up, if you need a reliable and solid model of the product you are going to release – use rapid prototyping technology, offering the best prototyping models that will never fail you.
