5 Reasons to be Cautious of Rapid Prototyping

Like any relatively new technology, rapid prototyping has many plus and minuses. In this article, we will be exploring some of the disadvantages of the RPM.

First, things first, just what is Rapid Prototyping? Rapid Prototyping is a form of additive based layer printing that utilizes CAD (Computer Assisted Design) to create scale models and prototypes. These prototypes can be used to round up investors for a new product, or for display purposes at shows, festivals, fairs and related events. It can also be used to test the functionality of a product for market viability.

Because of it's numerous uses, many people have gravitated towards rapid prototyping manufacturing, but the technology may not be beneficial to everyone.

This list is not in any order of importance and includes and is not limited to:

Post Manufacturing Design Flaws – Although a prototype created via 3D printing and CAD can be fairly stable, the additives used may not be suitable for every industry. For example, the medical and health related industries may find that the end product is not long term sustainable, which can cause problems when trying to demonstrate new techniques or products in the field. This is also largely be due to the fact that the tool surface finish is often rough, whereas many medical instruments have to be clean, clear and smooth. This is not to say that Rapid Prototyping may not be useful or other types of modeling, only that there may be a large variety of industries that may find this type of prototypical solution nonviable.

Not all that Rapid – although it has rapid in the name, truth be told, the 3D Additive Layering process can be rather time consumptive and lengthy. Indeed, building a single component could literally take several hours or days. This can be particularly problematic if one needs the item in question quickly. Developers and engineers beholden to a schedule may also find the slower process of little advantage to them. That said, a 3D printing option may be viable if there are no mechanical or moving parts involved.

The more mechanisms and parts that have to be designed, the longer the whole thing can take. This of course, leads us to another trouble area – Money – Depending on the nature of the project, 3D Printing can be cost effective or really hit the pocket book hard. As stated previously, people in the health or even aeronautic industries may not find additive prototype printing of benefit. A number of factors can create issues with cash flow as this industry often deals with complex machinery with moving parts. This will mean that models and prototypes are going to have to be mechanical in some way. Building a mechanical product with Rapid Prototyping will take a lot of time and can be budget draining.

Customization can be had, but may be limited – 3D printing and additive based rapid prototyping can reach fairly consistent measurements, but may only go so far in its intricacy. This limitation could create issues when it comes to the nuts and bolts aspect of a project. Engineers and designer who may desire to have their model be as true to life as possible for showcasing purpose may have to consider another option, such as EDM or CNC machining, to get the precision sculpting they need for a fine tuned, fully functioning prototype.

Making Changes – A plus and minus – it has been said that 3D Printing allows the client to make changes quickly, enabling them to tweak the end product to their liking. While this is true to an extent, there are code issues that can crop up that make this process a wee bit daunting. That said, these issues can be worked around should a client truly desire to utilize additive printing for their modeling projects.

If you are a designer or engineer looking to bring your content art to life, check out all the advantages and disadvantage of Rapid Prototyping before investing time and money. A qualified machining shop with ISO 9001:2008 certification would be your best bet, so shop around and investigate before you buy. It could be well worth the time and effort in the end.

CNC Machining is the Most Accurate Process for Prototyping

With advent of 3D Printing and Computer based design systems, some creators may over look a tried and true type of machining that provides precision models with high class 3D features. While many forms of model building can produce moving parts, CNC machining enables a designer or engineer to craft one of a kind models to spec. This further enable the prototype builders to come as close to the end product as is currently possible.

Rapid CNC Milling and Turning

CNC milling has been apart of the manufacturing industry for decades. Machinist engineers often turn to the process when they desire to produce parts and components that require the utmost precision and intricacy of design. CNC, e.g., computer numerical control equipment uses routers and grinders to achieve a finished product and although the process is largely computerized, it has to be overseen and guided by a skilled machinist who knows how to achieve optimum results.

These precision engineers utilize computer aided designs or CADs to implement codes based on mathematical formalizations to create even the most complicated parts. The base is generally an industrial grade material such as metal or plastic, which is shaped to form the complex parts needed for a final build. Depending on how large or small the project is, the procedure can take days to weeks to complete.

From Concept to End Product-Development

A reputable CNC machinist and/or machining shop will start with their clients base art or drawings prior to taking the next step of factoring out size and scale. Once that is determined, the CNC engineer can set up the equipment and begin to craft to object's moving parts. Prior to this however, is the all important choice in material. The chosen substance has to be able to withstand intense machining. From wood, to plastic and a plethora of metals, there are numerous industrial grade products to choose from in order to get started. After the proper material's are obtained, the CNC machinist begins to craft each individual piece. This is where the machinist 's skill and artistry come into play.

Fully Working Models

At the production end of things, the CNC machine does a good bit of the work, shaping the product to exacting specs so that it comes as close to the end product as possible. Because a CNC machine can quickly and efficiently create a fully functioning prototype that can be presented at trade shows and to potential investors, it can easily evolve around the customer's scheduling needs. This makes CNC machining one of the best options for amazing results that are affordable and long lasting. Be sure to comparison shop when on the market for quality CNC prototype creation. The best machining shops are ISO 9001:2008 certified, so be sure to inquire about this aspect prior to doing business with any parts or prototype manufacturing company.

Why Healthcare Systems Should Stay Away From Rapid Prototyping Manufacturing 
600 words OVERVIEW

Speed and efficiency can go hand and hand, but at times, depending on the processes or protocols used, it can mean a loss of production quality. This can be especially true when creating mechanized tools and parts. Dealing with the wrong machining processes can produce instruments that may not be up to par. This is problematic in the health care industry where human lives can literally hang in the balance. For this very reason, healthcare engineers may want to steer well clear of Rapid Prototype manufacturing to meet equipment crafting needs.

What is Rapid Prototype Manufacturing?

Rapid Prototype Manufacturing is a process used to build to scale visual or working models via CAD (computer assisted design). The end product is often created utilizing additive layering technology to bring to life a prototype that will be true to the designer's ideals. The process has been used in a number of industries with even sculptors and animators creating characters and works of art that can literally exist into a 3D, real world space.

The medical profession uses scale prototyping as well to produce life enhancing or even life saving equipment and components. These tools are generally designed to be primarily used in the health related fields. It all begins with the formulation of geometric data that is comprehensively evaluated so that all the necessary parts can be  aligned for precision building and eventual display.

The  Disadvantage in The Heathcare Fields

The term Rapid Prototype Manufacturing is a bit of a misnomer in that it can take several hours or days to create a working model. Adding to this inconvenience is the fact that it can be hard on budgets, as the equipment to craft these models  can be rather expensive. The resin and additives used for prototype crafting is not up the health system standards, as these materials can be rough  or hard to smooth. Medical equipment and tool surface finishes have to be precise .

End product durability is also called into question, as additive based substances generally cant weather a lot of wear and tear. To date, this relatively new technology is not compatible with the extremely comprehensive reliability needs of the medical establishment. Although many in the machining field feel the technology will eventually evolve to a more stable platform, and has a lot a of promise, it just isn't there yet.

Alternatives to Rapid Prototype Manufacturing

EDM (electrical discharge machining) and CNC (computerized numerical control) milling and turning are time tested, viable options with stellar reputations in the machining fields. Expert machinists often use these processes to craft high quality parts, components and prototypes that easily fit contemporary medical needs. Both of these techniques utilize state of the art equipment that can craft parts easily without sacrificing end product quality.

Why EDM is Dependable And Produces Quality Parts Time After Time

Modern technological advancements in the field of manufacturing has prompted the cultivation of cost effective fine tuning of contemporary machining processes, like wire EDM cutting and machining. EDM, which stands for Electrical Discharge Machining (EDM), utilizes a controlled series of electrical discharges to shape and mold comprehensive components and parts. The brilliance of this process is that it can fine tune even the tiniest mechanism to exacting measurement.

There is mathematical skill and precision to the work that enables machinists in the field to create products that always work as intended. This is especially important in medical, aeronautic or military defense industries, where precision matters. Those who have trained to work in the manufacturing trades understand the quality control mechanisms that EDM machining inherently provides. This understanding culminates in the kind of engineering that can be only described as meticulous.

Just how can EDM machining provide the exacting standards needed to ensure high caliber goods?

Simply put, qualified EDM machinists are trained in utilizing EDM cutting and milling techniques that provide unsurpassed attention to detail. This is largely due to how EDM machines streamline complex procedures. It begins with the basic plans, which are examined to ensure that the designers vision is met. When the final aspects are agreed upon, production begins, and this is when the magic starts. Utilizing a top  bottom axis, a machinist uses the EDM appliance to cut away at even the toughest steels or craft the smallest work piece. The wire in this process is not actually doing all the work here, what is actually happening during the procedure is the removal of small bits of material via electrical sparking. This allows the wire to move through the metal for crafting and shaping. Because these machines use mathematical computations to create real world dimensions, the results are exact to a tee. There are very few manufacturing processes that can match the stringent detailing of wire and EDM machining.

Wire EDM cutting and machining can be applied to virtually any type of industry grade materials as well. The process is also cost effective, allowing companies to order large units at premium bulk rate prices. Even so, the old adage of “you get what you pay for” applies. Not all companies hold to high quality production standards, and a too good to be true cut rate may be just that. If you want quality dependable parts, be sure to vet out the company to ensure you receive superior product no matter how large or small the scope of your project. And above all, start by looking into EDM machining and all it has to offer.

The Importance of Accurate Assessment in Using EDM vs Milling

Manufacturing has been an essential component to human survival since the dawn of mankind.This is due in part to the fact that humanity has had to craft simple tools in order to develop safe housing structures, hunting implements and other devices in order to grow and thrive. The very same holds true, even today. Thankfully, modern advancement has made essential part production a lot faster and easier than it has been in the past.

With industrial evolution comes a myriad of services and options that can be used to get the  job done, both smoothly and professionally. In regards to machining, talented engineers strive to use the best equipment possible in order to procure stellar results. For this very reason, EDM machining has fast become the gold star standard when it comes to crafting quality components and parts.

Even so, many companies still utilize time honored procedures like die mold machining, milling and cutting to create manufactured parts. These technique allow for smooth finishes, intricate designs and faster, more reliable results than ever believed possible.

While these processes are not a bad, EDM machining is often thought to be far superior when it comes to end product accuracy. Why? EDM machining specializes in product minutia, and is best used when one needs to create sharp internal corners, complex sculpting of intricate work pieces, shored or hard to craft angles and extreme, shallow depth cutting. EDM processed can be automated as well allowing for a faster, yet reliable production run.

Because essential industries like medicine, defense, and aerospace technology heavily rely on tools that have to perform consistently, the importance of accuracy cannot be over stressed. Just imagine a doctor using a life saving tool that malfunctions. A rocket or airplane taking off with faulty bolts or mechanics. Military weaponry or gear that doesn’t work as required. These scenarios are all too real if one considers using manufactured components that are sub par.

EDM machining accuracy is second none in the industry, which is precisely why manufacturing engineers opt to use this particular methodology time and again. This is not to say other types of milling or cutting do not have their place. Indeed, some types of parts may be better served with a die mold or old fashioned cutting process. That said, EDM machining is an industry standard for a reason and should be the go to option for any company seeking to ensure their all important manufactured products work whenever they are put into use.
