Rapid Prototype is a very popular process in the manufacturing, design, and medical industries. It help users to develop quick prototypes and obtain accurate feedback from their target audience.

The high demand for rapid prototype services can be attributed to a number of factors. These services help in eliminating design flaws at the conceptualization stage itself. There are a number of devices that assist in rapid prototyping; 3D Printers being one of them.

Numerous industry verticals require its services; especially those that are associated with design and development of products; the automotive sector being the most prominent of all.

In our opinion, having the support of a reliable vendor can be the source of a sustainable competitive advantage. If your vendor can ensure quick deliveries and provide innovative solutions to your problems then it will greatly reduce your time to market and help you churn newer versions of products with a faster turn around time.

Another advantage is in terms of the safety of intellectual property. Rapid manufacturing solutions tools like 3D printers ensure that your designs never leave the premises of your company and your intellectual property is safeguarded.

This industry is all set for exponential growth in the times to come. However, what is proving to be the biggest impediment to the growth of this industry is the high cost of prototyping machines. This problem is likely to be solved in the near future as demand for prototyping services increase, leading to higher supply and thereby lower MRP of the machines.

Rapid Prototype is in high demand in medical, engineering, and industry. With computers acquiring digital capabilities; users can input two-dimensional drawings and obtain three-dimensional models of their ideas. The availability of precise image manipulation software’s has helped designers to simulate designs with a remarkable degree of accuracy through the use of vectors.

Mathematically computed imagery helps in developing designs with a very low error margin of less than 1 millimeter. An example would illustrate this better. Suppose a group of surgeons want to operate upon the cranium of a patient but have not decided upon the right surgical procedure to be used. Rapid prototyping proves very helpful in such circumstances. By using a prototype of the cranium developed through a three dimensional printer; surgeons can arrive at a strategy before operating on a patient.

Thus, we see that rapid prototype has the potential to become the backbone of the medical, design and manufacturing industries and is certainly one of the gifts of the digital age to mankind.

You can visit this 3D Printer Prototyping Process webpage at: http://www.prototypezone.com/3d-models/

Here is an excerpt from the new 3D Printer Rapid Prototyping and Designing webpage:

“Technologies: Initially, production of a prototype required a lot of man-hours, tools, and experienced labor. For instance, after designing a novel Street Light Luminaire digitally, drawings used to be sent to accomplished craftsmen where the paper design used to be followed with utmost pains and a 3D prototype used to be formed in wood through the utilization of the entire shop that is full of costly tools and working machinery. One can easily make out that this process consumed a lot of time. Moreover, the skillful labor was not all that cheap. These shortcomings necessitated the need of rapid prototyping.

3D printing has a variation called Inkjet Printing System. It involves binding of fine powder layers (resins, cornstarch, or plaster) by the way of printing a gum from inkjet print head as per the shape of every cross-section as spotted by the CAD file. This is the only technology allowing full color prototypes to be printed. It is believed to be the quickest method.”

You can visit this 3D Printer Prototyping Process webpage at: http://www.prototypezone.com/3d-printers/

Here is an excerpt from the new 3D Printer Rapid Prototyping and Designing webpage:

“Working: All the 3D printers’ posses five basic process functions for creating a three-dimensional model.

First – The Print Surface is fed with a unique powder.

Second – The powder is spread on print surface by a roller at a preset depth. This process takes just a few seconds for its completion.

Third – Color is applied to the powder’s initial layer by the Standard Inkjet Print Heads.

Fourth – The solidification of powdered layer takes place.

Fifth – The lowering of print surface for powder’s another layer is enabled.

This process goes on repeating till the completion of the whole 3D model occurs. The mixture of Ink Jet Color and powder results in formation of a bond. The solidification occurs this way. So, if no printing is carried out at the specified layer or location, the powder retains its state, i.e. it does not get solidified. Once the printing process comes to a halt, the powder gets blown out, thereby leaving the output which is the reflection of the original model or drawing. Depending on complexity and size of output, this process takes around ½ an hour.”

For people outside the fields of engineering and technology, there can be some confusion regarding the terms “3D printers” and “rapid prototype machines.” This conundrum is to be expected since there are even engineers who are not aware that these machines exist.

Nonetheless, both these machines are used in fabricating scale models used in engineering, automation, manufacturing and mechanics. In recent years, however, the use of these machines has expanded beyond the confines of engineering to medicine, education, and even the arts. But what makes these machines different from each other?

What Are Rapid Prototype Machines?

The term “rapid prototype machine” actually refers to a wide range of machines that use many different technologies to create scale models. These technologies have names such as stereolithography, where photosensitive resin is shaped and hardened by a laser beam; solid ground curing, where the resin is cured with ultraviolet rays; or fused deposition modeling, where melted polymer is built in layers around a support structure.

Regardless of the technology used in these machines, the procedure used in creating models is almost uniform. A model is generated using CAD software, and the model is then converted into a file with an STL extension. The rapid prototype machine then processes this STL file by slicing it layer by layer. These layers are then produced on a platform using resin, and once completed the model is finished and cured.

3D Printers Are Rapid Prototype Machines

As for 3D printers, they are actually a subclass of rapid prototype machines. What makes them distinct from the other rapid prototype machines is that they are faster. The word “rapid” in rapid prototype machines can be misleading because creating models with them can still take days, even weeks. With 3D printers, you can have your model within a matter of hours, even minutes.

Most machines that are classified as 3D printers make use of inkjet printing technology, which is why they are called “printers” in the first place. This does not mean that 3D printers use inkjet technologies exclusively. There are such machines that also use derivatives of the fused deposition modeling process or the ultraviolet curing process. In 3D printers that use inkjet technology, the resin is sprayed on the printing platform using inkjet nozzles.

Another characteristic of 3D printers is that the base materials they use are usually non-toxic and do not require curing or finishing. This is a big contrast with 3D models created with stereolithography, for instance. In stereolithography, the resins that operators work with can become toxic if left uncured.

In addition, 3D printers are a lot less expensive. A starter 3D printing machine can cost US$15,000. While that figure cannot be considered cheap, it is relatively inexpensive compared to high-end rapid prototyping machines that can cost hundreds of thousands of dollars. There are also 3D printing machines that you can make on your own using starter kits and open source software.

Now you can print 3D color models so quickly and affordably, you’ll do it every day. Introducing the zprinter®450. The zprinter 450 makes color 3D printing accessible to everyone. The lowest priced color 3D printer available, it outputs brilliant color models with time-saving automation and an easy printing process. Z Corporation has introduced more innovations than any other provider of rapid prototyping solutions, including development of the fastest 3D printers, the world’s only color 3D printers, and high-definition 3D printing (HD3DP™) capabilities. Our 3D printers create physical models from computer-aided design (CAD) data by using an inkjet print-head to deposit a liquid binder that solidifies layers of powder. This cutting-edge technology supports a full line of 3D printers that deliver the speed, low operating costs, and high-quality models that product developers need to compete in today’s global market.

The technology used in rapid prototyping printers for producing 3D models is computer assisted design (CAD) software which directs hardware to precise specifications to produce three dimensional models. The efficiency of rapid prototyping to produce models for various companies and allow design changes to be made quickly and easily has found this technology an excellent solution for fulfilling their rapid prototyping needs. As the implications for rapid prototyping printers continue to develop the applications for the manufacturing of products is expanding. If a product is desired by the business they can simply purchase a CAD file upload it and use rapid prototyping printers to reproduce it. With fabrication materials for use in rapid prototyping printers continuing to advance the use of metals, plastics and polymers contributes to the wide application of rapid prototyping printers.

Convenience of Using Rapid Prototyping Printers

Rapid prototyping printers not only make product availability more convenient for companies but for consumers also. The technology once used only by manufacturers is now available for consumer use in their business or at home. Rapid prototyping printers provide an enhanced ability for the production of models and products. If a new brush or comb is desired, rapid prototyping printers can produce one very conveniently. Rapid prototyping printers can be used for a variety of products constructed of numerous kinds of materials. The technology used in rapid prototyping printers is computer assisted design software utilized to build a 3 dimensional model. The model is produced layer by layer until an exact reproduction is produced according to the specifications dictated by the program.

If a small business needs a product or model produced there is no need to maintain workshops with specialized tools or expensive skilled craftspeople as with traditional modeling. Rapid prototyping printers can provide the technology necessary to produce 3D models more conveniently and in shorter periods of time and for less money. In today’s business environment in order for a small business to grow the capability to produce products in a cost efficient manner is crucial for success. Rapid prototyping printers provide the technology for small businesses that are seeking more convenient and cost effective manufacturing options.

Growing Applications for Rapid Prototyping Printers

The computer assisted design applications of rapid prototyping printers are numerous compared to traditional prototyping methods. Traditional methods required the use of large, bulky and sophisticated equipment which also required a major investment for businesses to own. Rapid prototyping printers however are reasonably sized, compact and much less expensive. The set up time and simple operation has made rapid prototyping printers popular for creating models, machine parts and toys. The almost unlimited flexibility and potential applications of rapid prototyping printers to create replicas is a distinct applications advantage of this technology over traditional methods. If a CAD program can be created and suitable materials developed the application of rapid prototyping printers is immense.

Also, unlike some prototyping techniques the rapid prototyping printers produces no toxic chemicals from nor uses any toxic substances during the production process. Due to their safe operation the potential locations for where rapid prototyping printers can be set up and operated increases their application potential. Additional advantages gained from the application of rapid prototyping printers is that post production work is minimized, only the removal of excess materials produced during the production process is necessary. The applications of rapid prototyping printers are many including reduced costs, efficiency and safety. As new innovations for rapid prototyping printers are developed so will additional applications and markets open up as well.
