The Different Types Of Model Prototyping

Tuesday, August 30th, 2011

Rapid prototyping is an intensive process of collecting information on requirements and on the adequacy and functionality of fairly new product designs. Model prototyping is an important data resource during the different stages of product development. Model prototyping makes use of various kinds of rapid prototyping techniques to provide the right model types used for different testing procedures. Such techniques may require the use of requirements animation, incremental, and evolutionary prototyping.

1. Requirements Animation- is the method used mainly to demonstrate functionality in test cases that can be easily assessed by users. Software tools are used to produce representational prototype models that are built using animation packages as well as screen painters.

2. Incremental prototyping- enables the development of large prototype system models installed in phases in order to avoid delays between product specification and its final delivery into the consumer market. Once the customer and supplier have agreed on certain core features, the installation of a skeleton system is applied as soon as possible. Important requirements can be checked out as the model is being used, enabling changes to core features while in operation with extra and optional features can be added later.

I trust that what you’ve read so far has been informative. The following section should go a long way toward clearing up any uncertainty that may remain.

3. Evolutionary prototyping- considered as the most integral form of prototyping. It acts as a compromise between production methods and with that of model prototyping. Employing this technique, a model prototype is initially constructed that is then evaluated as it evolves continually and becomes a highly improved end product. Many designers believe that more acceptable systems would result if evolutionary prototyping were interconnected with periods of requirements animation or rapid prototyping. Here the tools are the actual facilities resources where the final system will be implemented.

The use of different model prototyping techniques can help do away with the uncertainties about how well a final design may be able to fit into the end user’s needs. The different model prototyping techniques help product designers make the necessary decisions by obtaining information from initial test users about the effective functionality of a certain product prototype.

Model prototyping can also be an effective aid in determining how effective and ideal the features and the overall design can be for proposed users. Model prototyping and the subsequent testing procedures can provide useful representation information that can reveal possible design flaws, effective features as well as useless functions that can either be corrected, enhanced or done away with on the next stages of product development.

The Benefits Of Rapid Prototyping

Thursday, August 25th, 2011

When most people think of Prototyping, what comes to mind is usually basic information that’s not particularly interesting or beneficial. But there’s a lot more to Prototyping than just the basics.

Rapid prototyping objects have been one of the many contributions of modern technology. Rapid prototyping makes it possible to make out and construct physical objects by using solid freeform fabrication methods. Different industries make use of rapid prototyping techniques to produce evaluation models and prototype parts of new products before they can ever be put into final production.

Having an evaluation model can help product developers look for certain design errors or further improve a new product before manufacturing them for the consumer market. This will ensure consumers of better quality products with little or no defects. All can be made possible through the use of rapid prototyping processes.

Rapid prototyping techniques can help reduce the many uncertainties about how well a new product design will fit the user’s needs. Rapid prototyping helps designers to assess and make better informed decisions by obtaining data from the initial prototype users about the functionality and features of a new product. Rapid prototyping techniques can provide additional information to designers that enable them to improve and correct possible defects on a new product before it can ever be put out into the market.

Hopefully the information presented so far has been applicable. You might also want to consider the following:

Rapid prototyping techniques can help product designers and developers come out with better quality products. Here are just some of the benefits of rapid prototyping:

1. Prototyping is very important at different stages of design. From conceptualization at the task level and determining the feature aspects of a new product, rapid prototyping techniques can help provide designers with a better visual as well as physical understanding of the product and see for themselves how their product will eventually fare out in the market.

2. Prototyping can be used to gain a better understanding of the kind of product required in the early stages of development. It can help designers keep track of the design improvements and possibly test out its effectivity with a control group.

3. Rapid prototyping techniques help product developers become more flexible as well as more creative in coming out with new products. It helps widen the room for improvement in terms of product design. Most people may tend to believe that once a good version of an product design is made, they can get easily carried away by thinking that this must be the only or the best possible design solution. By having prototypes made, designers may be able to think of other design approaches that they think will be better for a certain product concept.

To Prototype or Not to Prototype

Tuesday, August 23rd, 2011

In today’s world, it seems that almost any topic is open for debate. While I was gathering facts for this article, I was quite surprised to find some of the issues I thought were settled are actually still being openly discussed.

Simply put, prototyping is creating a functional and easily modifiable model, simulation or demonstration of a product such as a software.

Prototyping can be done before, during and later stages of developing the product. It is conducted before the start of the developing process to show that the concept is attainable, useful for the intended clientele and beneficial for the company.

Also by conducting prototyping at the beginning, the developers will know what specifications are needed and what features are preferred to be included in the final output.

Meanwhile, by conducting prototyping during the developing process, the developers will have an opportunity to check if the product is meeting all features and specifications and will have a chance to evolve these product characteristics into a better output.

When conducted in the later stages, prototyping can determine problems and possible solutions on the functionality of the product’s design. It allows changes to be made and various solutions to be implemented just before the full product version is released.

The more authentic information about Prototyping you know, the more likely people are to consider you a Prototyping expert. Read on for even more Prototyping facts that you can share.

One uses prototyping in order to lessen the communication gap between the developers and the target clients. Prototyping improves the communication flow which can increase the chance that the customers will accept the final product.

Prototyping is also used to clarify misconceptions about the product, assure output quality, manage alterations, increase user participation, gather valid specifications, and address various product issues like visibility and negative publications.

Even though prototyping can be done on mostly any project endeavor you will have to perform the process at the right time, at the right place and using the appropriate tools to achieve a successful and usable prototype. A successful prototype should be able to test the functionality of the product and evaluate a suggested product interface.

Prototyping also has a higher rate of success if it is utilized to compare various product designs, to explore results of design alterations, to identify market needs, to involve end users in the designing workflow, to draw out any fresh, possible or unexpected elements into the design, and if it is used later on to construct a larger and more complex model.

On the other hand, when your prototyping proved to be unsuccessful it’s most likely that you failed to create a clear set of criteria that would have determined when to end the prototyping process.

Prototyping failure also means that the consumer’s expectations were all accommodated which allowed it to go out of hand. If you applied all the operational functions of the prototype to the larger and final product and you find them lacking or did not meet product expectations then it means you made some errors during the prototyping process. It is also wrong to use prototyping to measure the future performance of a system that is still in the planning stage or use it as a marketing tool for a product that exists only on paper.

Of course, it’s impossible to put everything about Prototyping into just one article. But you can’t deny that you’ve just added to your understanding about Prototyping, and that’s time well spent.

What You Need to Know About Rapid Prototyping Systems

Wednesday, August 17th, 2011

Rapid prototyping is the method of constructing physical objects using solid freeform fabrication. The use of rapid prototyping techniques had its start during the 1980′s where it was used to build product models. Its current applications have been put into use in a wider range of objectives.

The technique can even be used in order to manufacture quality useable parts in small numbers. Rapid prototyping has even found some applications in the art scene where sculptors use the technology to create intricate shapes that become art pieces.

An improved digital rapid prototyping system makes use of computers in order to create highly accurate design pieces. A digital rapid prototyping system makes use of virtual designs usually created with the help of computer aided design or animation modeling software programs.

It seems like new information is discovered about something every day. And the topic of Prototyping is no exception. Keep reading to get more fresh news about Prototyping.

The system then transforms the design into virtual cross sections which a special machine uses to recreate the exact design cross sections in physical space until a physical model is finished. The highly technical process enables virtual designs to take physical shape in very exact and accurate manner.

In rapid prototyping, there are usually two basic approaches to design systems being used. The approach chosen can either be formative or summative. The formative approach is being used for situations wherein the prototype is first built based on the current stage of the design. It is then tested on a control group with the results being used to integrate into the next stage of development in order to further enhance and improve on the usefulness of the current design.

The summative approach on the other hand takes a different course in developing product design. A single test exercise is performed at the end of the overall design enhancing process. At most times the approach is a two step stage. Following the summative approach can sometimes make it too costly to make design changes as the end stage nears.

But this approach is less time consuming and can be more cost effective initially if the projected design is seen to require little refinements when a prototype is done. But in the long run, using the formative approach will definitely be more beneficial. The main reason for this is because when a system is tested as a whole only once at the end of the design period, it may be very difficult to pin point the various flaws that may exist within the design.

Is there really any information about Prototyping that is nonessential? We all see things from different angles, so something relatively insignificant to one may be crucial to another.

Simple Ways to Do Prototype Refactoring

Tuesday, August 16th, 2011

Many years ago, people used to rely on Lotus 123 to get work on the computer. WordStar was the program of choice when preparing documents. Years later, Microsoft hit the market that was followed by other operating systems such as Linux and Macintosh.

Ever since Microsoft started in the 1990′s, various improvements have been made and the latest edition to the family is Windows XP. Why the upgrades some may ask? This is to satisfy the requirements of businesses and end users who are not satisfied with the current systems.

How does the company know that people are not satisfied? When systems fail, a report is generated that is then sent to the corporate office. Software designers will then find answers to this problems and then release product updates or a new program to the public, which is what prototyping, is all about.

But there are many ways to create a new prototype. The most common, which is making a few alterations to the program, is what is called prototype refactoring. After all, computer codes are identified in numbers such as 1 or 0 and most users want he problem fixed rather than going out and buying a new one.

This case also applies for automobiles so a customer who had a problem for example with the automatic transmission system will go back to the dealer to have this repaired instead of buying a new car.

Think about what you’ve read so far. Does it reinforce what you already know about Prototyping? Or was there something completely new? What about the remaining paragraphs?

Software developers usually try to solve two contradictions in order for it to work. This is like hitting two birds with one stone so a lot can be achieved with less effort and here are a few ways how this is done.

The first is by reviewing the HTML application that can be edited using Macromedia Dreamweaver. When the changes have been made, this can be saved and an update can be sent to the end user.

The second is by using MS Visio. This is better known as a drawing tool but those who are experts in making programs also use this to make alterations in the settings panel to make it work.

The last is by doing something with the worksheet compiler. Believe it or not, developers can make improvements by simply using tools such as Microsoft Word or Excel.

The three just mentioned proves that there are ways to conduct prototype refactoring without doing a major overhaul of the system. The fact is, the system works and the software developer has to fix a few glitches.

Now might be a good time to write down the main points covered above. The act of putting it down on paper will help you remember what’s important about Prototyping.

Fast Pace Prototyping Services

Tuesday, August 2nd, 2011

Rapid prototyping, otherwise known as desktop manufacturing, additive fabrication, solid freeform fabrication, three dimensional printing or layered manufacturing, has always been in the forefront of development and design.

By quickly creating prototypes that are similar to form and function as the actual production unit, developers are able to create a product that meets the expectations of consumers and project sponsors.

Through a combination of rapid prototyping methods and traditional model making, high quality prototypes can be created with less the expense and quicker turnaround times.

Compared to traditional fabrication methods like milling and turning, rapid prototyping is way better in terms of accuracy, speed and quality. By using rapid prototyping techniques complex and intricate shapes can be formed without any complicated machine setup, prototypes can be created from different types of materials or composites, and the process simplifies the whole process of creating a prototype.

Because of the advantage it brings, rapid prototyping services are being offered by companies to engineers and system developers to better understand their product and communicate better with their target clientele. Not only does the technique used by designers, developers and manufacturers, but professions like surgeons, architects, artists and even mere individuals regularly utilize the technology.

Knowledge can give you a real advantage. To make sure you’re fully informed about Prototyping, keep reading.

Among the services being offered are stereolithography, selective laser sintering or SLS, fused deposition modeling of FDM, laminated object manufacturing or LOM, inkjet-based systems and three dimensional printing or 3DP.

SLS is one of the most used tools in rapid prototyping techniques. In SLS rapid prototyping, a CO2 laser is used to melt powdered thermoplastic materials to create layers. A scanner guides the laser and melts specific areas and materials based on the information fed by the 3D CAD.

Prototypes created from SLS processes are strong and more tolerant to stress. Materials used in the market include DuraForm, CastForm, Somos 201, FR85A and LaserForm. Most of the prototypes created from these materials are usually ready to be used and only require minimal clean up and finishing.

Stereolithography or SLA creates prototype part layers through the use of a solid-state laser. The 3D CAD data guides the laser as it cuts through the surface of a container which normally contains liquid photopolymer material.

In LOM, on the other hand, uses a paper sheet with one side laminated with adhesive. The laser cuts the outline on the paper sheet. This process does not involve any chemical reaction which makes it cheaper and large parts can be made.

Medical Prototypes

Thursday, July 28th, 2011

Do you ever feel like you know just enough about Prototyping to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from Prototyping experts.

With all the recent technological advancements in the area of medicine, it is no wonder that doctors the world over have started shifting its dependence on the computer for virtual models. Instead, they are now turning into actual prototypes, which these computers have produced in the first place.

In the recent past, it was considered a medical breakthrough for doctors and surgeons to be able to make use of accurate 3D computer images to simulate complex surgical procedures or physical processes. Now though, with the continuous developments in the field of medical device prototyping, these 3D computer images are now fabricated into actual models to replicate the complexity of the virtual images. This means that now, doctors and surgeons can study and simulate complex surgical procedures without having to risk using a live physical being or be limited by virtual images on a screen.

No matter how life like and realistic these 3D computer images are, nothing beats the experience of being able to work with something concrete. This has made medical device prototyping a truly remarkable procedure that has revolutionized the medical industry.

Hopefully the information presented so far has been applicable. You might also want to consider the following:

At the onset, medical prototyping was used to build models of medical products and instruments. However, with more people using the technology and with continuous developments in this area, medical practitioners have begun to realize other possible applications for this technology.

Now, more and more complex medical device prototyping is utilized to fabricate models for cadavers that can be used in training medical students. With the proper materials, these prototypes can be used over and over again, or at least for a prolonged period of time.
Medical device prototyping is not only for educating medical students.

Expert surgeons also benefit from this technology through the use of prototypes to model and simulate complex bone and tissue connections and systems so that they can further study and examine how best to go through a medical procedure. These medical device prototypes are made to simulate actual anatomical reactions to that if for instance, an incision is made on the anatomical prototype, blood like substances can ooze from it to simulate a real incision on real human flesh.

There are many types of prototype service providers that provide medical device prototyping. With more and more competition among these providers, the medical industry can be assured of more competitive prices, practices and services which in the end, benefit society as a whole.

This article’s coverage of the information is as complete as it can be today. But you should always leave open the possibility that future research could uncover new facts.

Find a Prototyping Solution

Wednesday, July 27th, 2011

A solution is the result of the method or process of finding the answer to a problem. A business is a complex system that, simply put, needs to constantly find solutions to problems tied to productivity and cost. Now, each business has a product. It may a tangible product that needs to be manufactured, or it may be a service that in turn offers a solution to another individual or business problem.

In the case of products that need to be manufactured, the problems are still tied to costs, productivity and efficiency. In short, when it comes to producing products, the development process needs to be done in the shortest amount of time and money with the assurance of increasing the business’ bottom line.

However, the process of development can be very tedious. Many prototypes can be made to refine a product before it is even produced and launched. Creating prototypes is a problem in itself because of the amount of effort and time it can potentially consume. This is why the solution to this problem was to utilize computer aided designs or CAD, where one can create the design using virtual 3D models on screen to test a product.

Is everything making sense so far? If not, I’m sure that with just a little more reading, all the facts will fall into place.

Prototyping From The Virtual To The Physical World

Sunday, July 24th, 2011

Have you ever wondered what exactly is up with Prototyping? This informative report can give you an insight into everything you’ve ever wanted to know about Prototyping.

Virtual prototyping is becoming a cost-effective method used in testing new products and systems. It is an integral part of current rapid prototyping methods wherein virtual designs created from computer aided design (CAD) or animation modeling software are used and then transformed into cross sections in a still virtual environment.

A special machine is then used to create each virtual cross section in then takes physical form layer after layer until an identical prototype model is created. The whole process enables the virtual model become a physical model with corresponding identical features.

In the additive fabrication of virtual prototypes, the rapid prototyping (RP) machine reads the data from a CAD drawing, and forms successive layers of liquid or powdered material according to the virtual data received. It slowly builds up a physical model from a series of cross sections.

These different layers, which match up to the virtual cross sections created from the CAD model, are then glued or fused together to create the final three dimensional prototype model.

The information about Prototyping presented here will do one of two things: either it will reinforce what you know about Prototyping or it will teach you something new. Both are good outcomes.

All the rapid prototyping technologies in current use have many things in common. All make use of additive processes. Rapid prototyping makes use of additive construction as the means of creating solid prototype objects which has the distinct advantage of creating almost any shape or form that even the best machining and tooling methods may not be able to achieve. During the ensuing development, virtual prototyping goes through a number of stages that eventually turns designs into fully testable three dimensional models.

All the rapid prototyping machines being used slowly form the three dimensional models by putting together thin, two-dimensional layers one at a time. The three dimensional manifestation of the virtual design is formed from the bottom up. Models are formed on an elevator-like platform from virtual CAD designs. The platform is lowered a layer-height at a time once a layer is completed. The thinner the layer, the smoother the finish will be on the completed prototype model. Once the model is completely formed, it may be sanded, plated or painted, depending on material used.

Rapid prototyping technologies can either be a “dry” or a “wet” process. Most machines create prototype models by solidifying some sort of loose powder, liquid, or semi-liquid material. A machine may be able to cut through adhesive-coated sheets of prototype fabrication material. The dry powdered materials can either be some sort of polymer, powdered metal, or wax. Some machines may even be able to use starch as the building material for forming the prototype model.

Some of the powders used may also require a binder. The liquid materials mainly used are usually photosensitive polymers that solidify when exposed to either a laser or ultraviolet (UV) light. Wet rapid prototyping methods generally require a curing phase.

PCB Prototyping Advantage

Friday, July 22nd, 2011

Advancement in technology and computerization paved way to convenience in mass production of PCB/s worldwide. Prototyping is a modern system used for cost effective manufacturing of PCB boards, primarily a main electronic component.

Being aggressively introduced to companies, prototyping machines are not ordinary commodity like a photocopy machine, which users can use at once with ease. PCB machines need careful study and training before it can take off for efficient use. As a modern, priced item and investment, it takes a lot of experience to judge the equipment before acquiring one.

The basics of PCB Prototyping

BENEFITS – If a business involves mass production, the first process is making master copies for checking before it can be carried over to the next step of producing millions. With PCB milling system, the tedious traditional process is lessened because of the speed of creating and testing is guaranteed.

Truthfully, the only difference between you and Prototyping experts is time. If you’ll invest a little more time in reading, you’ll be that much nearer to expert status when it comes to Prototyping.

CHEMICAL FREE – compared to chemical etching, PCB milling is cleanly done by subtractive method without involving the use of chemicals. Circuit boards are cut through to remove the copper portions. The speed in accomplishing the task is controlled by the user with great accuracy.

COMPACT – Imagine one machine handling the multiple complex tasks of milling, drilling, routing, and other special processes, where task are all done by prototyping machine to make PCB boards. The only additional item required for operating the equipment is backing it up with industrial vacuum cleaner for maintenance purposes. The compactness can be achieved in the setup process, which is also a part of training required in handling prototyping machines.

MECHANISM – PCB prototyping is a precision-controlled device that is highly mechanical in make. It involves drive systems fully manipulated by engineered assembly. Once put up, everything depends on the user and the integration of software coordinating the movement of the heads in its coordinates (x, y and z). It is computerized making repetitive process free of errors.

SAFE – designed for high sophistication with the use of small bits for routing, it has been customized for rigidity of application. However, for safety reasons, user is required to wear protection glasses for the eyes. Minute dusts emitted are required to be vacuumed off all the time.

Years of experience will be enough to efficiently use PCB prototyping machines. It made manufacturing safe, easy, productive and rewarding in general. It is best to get upgraded in technology especially with use of computerized equipments.
