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.

The 3D Printer Rapid Prototype Design Process is a new webpage that was just added to the new Prototyping Website that has just been released. This new 3D Printer Prototype webpage has all of the information you need to know of 3D Printing and 3D Prototyping and the main information you need to know on 3D Printer Rapid Prototyping. 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.”

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.

Industrial design was revolutionized with print 3D technology. Everything from a computer mouse to a mountain bike has been excellently shaped by using 3D. This technology has been responsible for the advanced contours, lines and dynamics of new production.

Rapid Prototyping Technology

Before the advent of 3D printing, prototypes had to be painstakingly crafted by master craftsmen in a large workshop using specialised tools. A perfectly proportioned wooden prototype generally required several days to complete even with the employment of highly skilled and proficient labour. There were significant delays between the design stages of a project to the prototype stage. Finalised drawings took ages to be translated to a workable model as the illustrations had to be carefully followed to avoid error.

Rapid prototyping developed from a need to produce the physical model in a shorter time span at much less cost. You can now use this technology to print 3D models on your printer with a high attention to detail and accuracy. Consecutive layers are printed to previous ones to build up an image that can be used for traditional wax or high tech epoxy moulding.

Self-Replicating Printers

The “self-replicating rapid prototype” or RepRap that is currently in the pipeline will allow you to create unique and novel ideas that are functional in a short space of time. Three-dimensional objects could even be printed at home with the anticipated reduced price of RepRap compared to conventional 3D printers. Rapid prototyping would be taken to a new level as medical equipment manufacturers, industrial or jewellery designers and automotive engineers can create complex products and artefacts without the need for costly industrial infrastructure. The common speculation is that, with the technology to make another version of the original, you can quickly construct spare parts and defective components with low-level resources. The ideal envisaged is a future where you could design and manufacture your own mechanical device in the comfort of your home.

Cost Effective 3D Printing

If you’re a small or medium sized company, you can now print models of your products that very closely resemble and feel like an actual prototype. The price of 3D printers has become much more affordable of late. Instead of outsourcing your requirements to large industrial concerns, you can greatly reduce the associated costs by printing the parts in-house. You can make models of objects with different physical properties having vastly contrasting mechanical components in a single process of building. You don’t need to assemble several distinct parts separately and then combine them into the final product. Your finished prototype will be an almost perfect match of the target design.

You can easily print 3D artistic and imaginative models of geckos and gargoyles with your printer. Precious and delicate design for jewellery to cultural heritage artefacts can be replicated with the latest technology in 3D printing. With RepRap fully functional, you may even be able to create an automotive spare part for your car in your home and skip a visit to the auto repair shop.

Here is an excerpt from the new Rapid Prototyping Services and DIYPrototyping webpage:

“Several DIY Rapid Prototyping techniques have come up off late. Making a 3D printer at home can prove to be quite cost-effective. The other names for such sort of prototyping are fabbing, three-dimensional printing, reprapping, and fabrication. RepRap is one such 3D printer. Let its making be studied in detail.

RepRap: RepRap is the abbreviation for Replicating Rapid-prototype. In other words, it can be said to be a Practical Self-copying Printer. RepRap would make metal, ceramic, and plastic parts. It’s itself made up of plastic. This is done in order to facilitate the making of multiple copies of its own self. The final product can be described as a 3-axis robot moving numerous material extruders. Fine filaments are produced by these extruders. The filaments are made up of their own working materials. This process has a paste-like consistency.”
