Rapid Prototypes And CNC

03/19/2009

Before the Rapid prototype technologies made its appearance in the market, the traditional CNC had the sway. However, with the coming up of the new technology the older one is now on the wane.

It does not mean that the new technology does not face criticisms or there are no such people who even today prefer subtractive CNC methods. The main criticism leveled by such people against rapid prototyping is that it is never a solution to each and every fabrication problem faced by the manufacturing industry.

Proponents of CNC claim that the older technology was easily comprehensible. It offered you the scope of selecting materials from a host of items. It is also excellent for accuracy though may be lagging behind the prototyping system in terms of speed. However, even the best proponents of CNC agree that when it becomes necessary to produce some part or the object with even moderate complex geometry, prototyping is perhaps the better technology.

The reason is that CNC is neither suitable to address complexities nor it is as fast as the rapid prototyping method. With CNC you cannot expect migrating from STL to part in 24 hours that fast as is possible with rapid prototyping. Moreover the accuracy in case of rapid prototyping is as good as that of CNC. Therefore the methodology is quite adequate for a large and wide range of applications for exacting them.

Don’t forget to spend some time in learning before opting for rapid prototyping services

03/13/2009

Like all other types of technologies, rapid prototyping also involves a lot of complications. It is due to these complications that it is hard for an average Joe to really understand what type of services he should expect from a company.

If you are also interested in using the option of rapid prototyping, you must spend some time in learning a little more about this particular technology. It is essential because it will help you to get the best results after consulting with a company.

The most important thing to keep in mind is that there different companies make use of different types of machines and these machines come with specific limitations. By learning more about these limitations, you will find yourself in a position to make a decision about using the services of a company.

A good example to clear things is about SLA machines. These are the machines which are usually used for the prototyping but you may have to deal with some problems related to the size of features. Also, some people have complained about the wall thicknesses, which is due to the limitations related to layer thickness.

So, educate yourself more about these technicalities as you will be in a better position to make a decision. But, if you don’t want to spend time in learning, you must at least try to work with a professional company like the one found over Solidconcepts.com. It doesn’t matter if you need rapid prototyping, direct digital manufacturing or tooling and injection molding services, you will always be able to get all types of services through this site.

Designers Favor Rapid Prototyping

It goes without saying that designers in all parts of the globe are becoming attached to the process of rapid prototyping in a marked manner. The concept of same day parts is now growing popular. One of the reasons is that in the past the designers found it both time consuming and expensive to obtain the prototypes of objects as they were made using the traditional subtractive technologies. In result they could never get the prototypes quickly.

On the other hand the geometric control that rapid prototyping allows the designer ensures economic manufacturing of the objects. When you are going to have millions of specimens of the same object there may be no harm in going for expensive machines and technologies. The inconveniences can be neutralized by spreading over the costs that will automatically come down due to numerical strength and superiorities. However, the same machines could turn out to be too expensive propositions when it comes to manufacturing only 10-100 specimens of the item. In such cases rapid prototyping is the only solution.

Pay less and get more at a faster rate is the essence of rapid prototyping technologies. It could even enable you to shelve the tools altogether and fabricate the object directly in its final shape. Even more important aspect of the popularity of rapid prototyping is that you may not need any physical part at all. Virtual prototyping is now catching the imagination of designers. This can be easily achieved with the use of computers and simple CAD software.

And even when it comes to the physical part, same day shipping for custom designed parts could only be possible with technologies like rapid prototyping.
