Concept Model: a physical model made to demonstrate an idea. Concept models allow people from different functional areas to see the idea, stimulate thought and discussion, and drive acceptance or rejection.
Prototyping Attributes
Speed: turnaround time to convert a computer file into a physical prototype
Appearance: any visual attribute: color, texture, size, shape, etc.
Assembly/Fit Testing: making some or all of the parts of an assembly, putting them together, and seeing if they fit properly. At the gross level, this checks for design errors, such as placing two tabs at 2 in. spacing and the mating slots at 1 in. spacing. At the fine level, this is a matter of minor dimensional differences and tolerances. Obviously, any test involving tolerances needs to use the actual manufacturing process or one which has similar tolerances.
Prototyping Attributes
Form: the shape of the part: features and size
Fit: how the part mates with other parts
Functional Testing: seeing how a part or assembly will function when subjected to stresses representing what it will see in its actual application.
Prototyping Attributes
Chemical Resistance: resistance to chemicals including acids, bases, hydrocarbons, fuels, etc.
Mechanical Properties: strength of the part measured by tensile strength, compressive strength, flexural strength, impact strength, tear resistance, etc.
Electrical Properties: interaction of electrical fields and the part. This may include dielectric constant, dielectric strength, dissipation factor, surface and volume resistance, static decay, etc.
Thermal Properties: changes in mechanical properties that occur with changes in temperature. These may include thermal expansion coefficient, heat deflection temperature, vicat softening point, etc.
Optical Properties: ability to transmit light. May include refractive index, transmittance, and haze.
Life Testing: testing properties that may change with time and that are important for a product to remain functional throughout its expected life. Life testing often involves subjecting the product to extreme conditions (e.g., temperature, humidity, voltage, UV, etc.) to estimate in a shorter period of time, how the product will react over its expected life.
Prototyping Attributes
Mechanical Properties (fatigue strength): ability to withstand large numbers of load cycles at various stress levels.
Aging Properties (UV, creep): ability to withstand exposure to ultraviolet light with an acceptable amount of degradation; ability to withstand extended applications of forces to the part with acceptable levels of permanent deflection.
Regulatory Testing: testing specified by a regulatory or standards organization or agency to assure parts are suitable for a particular use such as medical, food service or consumer application. Examples include Underwriters Laboratory (UL), the Canadian Standards Association (CSA), the U.S. Food and Drug Agency (FDA), the U.S. Federal Communications Commission (FCC), the International Standard Organization (ISO) and the European Commission (EC).
Prototyping Attributes
Flammability Properties: the resistance of a resin or part to ignition in the presence of a flame.
EMI/RFI Properties: the ability of a resin, part or assembly to shield or block Electromagnetic Interference or Radio Frequency Interference.
Food Rating: approval of a resin or part to be used in applications where it will come in contact with food while it is being prepared, served or consumed.
Biocompatibility: the ability of the resin or part to be in contact with human or animal bodies, outside or inside the body, without causing undue adverse effects (e.g., irritations, blood interactions, toxicity, etc). Biocompatibility is important for surgical instruments and many medical devices.
Prototype models help design teams make more informed decisions by obtaining invaluable data from the performance of, and the reaction to, those prototypes. The more data that is gathered at this stage of the product development cycle, the better the chances of preventing potential product or manufacturing issues down the road. If a well thought out prototyping strategy is followed, there is a far greater chance that the product will be introduced to the market on time, be accepted, perform reliably, and be profitable.
What is the best way to get a prototype made? The answer depends on where you are in your process and what you are trying to accomplish. Early in the design process, when the ideas are flowing freely, concept models are helpful. As the design progresses, a prototype that has the size, finish, color, shape, strength, durability, and material characteristics of the intended final product becomes increasingly important. Therefore, using the right prototyping process is critical. In order to most effectively validate your design, pay close attention to these three key elements of your design: functionality, manufacturability, and viability.&#;
If your prototype can faithfully represent the attributes of the end-product, it is by definition functional.&#;These requirements often include such things as material properties (e.g., flame resistance), dimensional accuracy for fit-up with mating parts, and cosmetic surface finishes for appearance.
If your prototype design can be repeatedly and economically produced in a manner that supports the requirements of the end product, it is by definition manufacturable.&#;These requirements include the ability to maintain the functionality of the design as described above, keep the piece-part cost below the required level, and support the production schedule. No matter how great a design is, it will go nowhere if it can&#;t be manufactured. Make sure your prototyping process takes this into consideration.
Finally, even if your prototype design is functional and manufacturable, it doesn&#;t mean anyone will want to use it.&#;Prototypes are the only true way to verify the viability of the design in this sense.&#;If your design can also pass the challenges associated with market trials (e.g., trade show displays, usability testing) and regulatory testing (e.g., FDA testing of medical devices), you&#;re well on your way to a successful product launch.

Conclusion
Rapid prototyping services are essential to the modern economy. The process helps support sustainable development by efficiently fabricating physical parts, models, and assemblies. RP involves building a 3D computer-aided design (CAD) for precision manufacturing. Many fab shops use 3D printing to form complex components with minimal waste quickly.
Companies providing rapid prototyping services typically offer shortened lead times, improved accuracy, and decreased operational costs. However, RP is usually a substantial upfront investment. Product development teams must weigh the pros and cons to determine the most efficient approach. They can also talk to machine operators, engineers, and specialists to decide.

Rapid prototyping services allow you to design parts or assemblies while perfecting the blueprint. However, you must use the appropriate techniques based on your concept complexity and industry standard.
Understanding the various rapid prototyping approaches is crucial. This knowledge can help you create better parts for less money and in less time. It can also help you avoid some drawbacks to rapid prototyping services from less scrupulous providers.
First, companies use rapid prototyping services for individual parts instead of complex assemblies. Specialists help develop specific elements that fit together perfectly for optimal functionality. RP should reveal the issues of each component for testing and evaluation before mass manufacturing. It should not represent your final product.
Second, many companies categorize their prototypes based on their degree of accuracy. Other criteria might include the development stage and product purpose. The RPS you choose will determine outcome quality, so don&#;t forget to ask questions.
FACT: You can pay for low-fidelity or high-fidelity prototypes for different applications. Each product will have unique functionality, dimensions, and appearance.
Highly regulated RPS comes with multiple advantages. Experts say you can design better and faster with this new technology. That&#;s because the benefits of rapid prototyping are evident even within the first few phases of development.

Rapid prototyping services are imperfect, with several improvements still in the works. Many engineers find the results less helpful than required because of a vast misunderstanding of the process. For starters, RPS is not the same as 3D printing.
RP does not render a final product but instead creates a digital model close to the real thing. You must also invest in additive manufacturing or CNC machining to develop a high-quality end-use product. Talk to your team for more specific information about lead times and manufacturing costs.
Here are some of the drawbacks to discuss:
Another concern is end-user confusion, as customers mistake the prototype for the finished product. Teams must communicate their objectives clearly to avoid uncertainty and chaos or face backlash when introducing new designs to stakeholders. Thus, depending on whether function or fashion are more important, RPS might not be the best answer.
TIP: Be careful not to overlook critical features that can&#;t be prototyped because they can negatively impact testing results.
Choosing the best rapid prototyping services can be challenging, especially when time is of the essence. Short lead times aren&#;t always possible with complex designs. The materials also play a significant role in scheduling and budgeting, so learn the various elements before setting expectations.
You can consult your team for advice, but prepare for discussions about the following considerations:
Do you need high-quality prototypes, or can you get by with something rudimentary? Set realistic expectations based on your objectives. That way, you&#;re not disappointed if your models come out too simple or unfit for the market.
Meanwhile, pick a provider that can produce high-quality outcomes despite the challenges. Exceeding industry standards helps place your company above the competition more quickly. Rapid prototyping services save time and reduce overall expenses, even if you create several models or pay exorbitant upfront fees.
TIP: Don&#;t expect your prototypes to be perfect; expect precision.
Consider the design intricacy when choosing rapid prototyping services. Some companies cannot fabricate every component of an assembly without outsourcing or improvisation. You likely want a one-stop shop to help cut costs and streamline processing. Ask your provider how they conduct business to determine efficiency.
Complex designs might require more time and attention, depending on several factors. The geometries, materials, and purposes can also affect the pricing and timing, so shave expenses where you can. Use RPS to develop flawless parts to a practical whole. Then choose the most efficient methods to manufacture orders.
TIP: Treat the prototyping phase as an opportunity to get answers about your design.
What is the desired look or function of each design? Determine the perfect prototype fidelity before launching a project to avoid unnecessary expenses and wasted time. High-fidelity prototypes help teams refine various details to prepare them for the final implantation. Low-fidelity prototypes demonstrate different design elements for examination, troubleshooting, and retooling.
You can tailor rapid prototyping services to suit unique objectives and meet deadlines. Pick between faithful functionality or fashionable presentation or find a happy compromise. Consult your team for insights on each design&#;s desired aesthetic and behavior, then iterate those requirements to the manufacturing crew for a smooth operation.
TIP: More precise RPS usually requires advanced tools and software.
Match RPS with your goals and maintain a flexible budget for unexpected expenses. Fast manufacturing can be unpredictable depending on these evolving factors:
Talk to your crew about how supply chain disruptions and advanced CAD software can impact your RP objectives.
If you&#;re looking for rapid prototyping services, then you&#;re likely asking the following questions:
Answering all those questions can be challenging without some basic information. However, these three tips should help clarify:
The experts providing rapid prototyping services cannot decide your design&#;s purpose. That&#;s something you must do before initiating a project. However, prototyping specialists can help you determine your most productive, efficient, cost-effective strategy.
Many people consider rapid prototyping services fast manufacturing because of the expedited modeling capabilities. However, some orders could take longer than others. Your project deadlines are essential, but multiple variables could fudge the schedule. Plan accordingly.
Choose rapid prototyping services that are flexible and affordable. You shouldn&#;t pay for mistakes made by staff, but forgetting details or overlooking specifics can cost you. Talk to your team about ways to reduce expenses while maintaining your prototyping integrity.
Don&#;t forget the impact of materials, suppliers, ISO standards, and industry trends on your overall experience. Manufacturing facilities offering RPS cannot control every aspect of the process. You must practice due diligence to get the most out of your investment.

Pricing and scheduling RPS can be tricky. There are multiple factors to consider, and each project is unique. Meanwhile, only the experts understand the finer points of fast manufacturing with sophisticated technology. Amateur attempts can lead to accidents, oversights, and disasters.
Prepare for a meaningful meeting with your team by studying these special considerations:
Material prices and tooling costs can vary depending on the location and supplier. However, your service provider cannot control the impact of inflation on manufacturing. Account for changing interest rates, shifting import/export fees, and other unexpected expenses.
Supply chain disruptions can lead to material shortages that might impact your bottom line. Limiting imports, exports, and order sizes can also affect your project outcomes. Consider the global marketplace before judging the service provider for its restrictive policies.
Laws could determine the possibilities for manufacturers seeking RPS. The reason is that some industries can change their best practices after new discoveries or innovations. Maintaining ISO standards can be a challenge for the wrong provider.
Rapid prototyping service quality depends heavily on facility competence. If the company struggles to keep up with the latest manufacturing technology, it&#;ll likely charge more for RP. Ask to see a portfolio of past work or discuss the limitations before setting expectations.
Rapid prototyping services vary widely based on multiple factors, so learning to discern is essential. Engineering teams can use these advanced manufacturing techniques to expedite product development and cut production costs. However, RPS might not be suitable for every application. The price and timeline depend on the materials, complexity, design, and provider.
