Answer. The four types of starting materials in RP are (1) liquid-based, (2) powder-based, (3) molten material, and (4) solid sheets. Besides the starting material, what are the layer-forming processes by which each layer is created in rapid prototyping technologies?

Here are four steps to get your first prototype built so you can turn your idea into a patented, profitable product.

1. Create a Concept Sketch. The first step toward turning your idea into reality is getting it down on paper.
2. Develop a Virtual Prototype.
3. Build a Physical Prototype.
4. Locate a Manufacturer.

The process of rapid prototyping can be presented as a cycle with three stages.

1. Prototyping. Creating a solution that can be reviewed and tested.
2. Reviewing. Giving your prototype to users/stakeholders and gathering feedback that helps you understand what’s working well and what’s not.
3. Refining.

How does Rapid Prototyping Work? Rapid Prototyping, also known as 3D printing, is an additive manufacturing technology. The 3D printing machine reads the data from the CAD drawing and lays down successive layers of liquid, powder, or sheet material — building up the physical model from a series of cross sections.

In manufacturing, rapid prototyping is used to create a three-dimensional model of a part or product. In addition to providing 3-D visualization for digitally rendered items, rapid prototyping can be used to test the efficiency of a part or product design before it is manufactured in larger quantities.

The most important advantage of a prototype is that it simulates the real and future product. It can help attract customers to invest in the product before allocating any resources needed for implementation. You can test the design’s correctness before it comes into production and you can discover design errors.

Benefits of high-fidelity prototyping Pinpoint specific components to test: You can dive deep into a single component (like flow, visuals, engagement, or navigation) during user testing. This allows you to get detailed feedback on certain elements of the design that would not be possible with pen and paper.

In this sense, a high-fidelity (sometimes referred as high-fi or hi-fi) prototype is a computer-based interactive representation of the product in its closest resemblance to the final design in terms of details and functionality.

High-fidelity prototyping — is highly-functional and interactive prototyping which is quite close to the final product, with lots of functionality and details included. This is often used in the later usability evaluation to discover the potential issues that may exist in the workflow, interactivity and so on.

Prototypes exist for a reason: to test and validate assumptions, test our ideas for solutions, or explain and flesh out ideas. Prototyping for the sake of prototyping can result in a lack of focus, or prototypes with too much detail (i.e., a waste of time) or too little detail (i.e., ineffective in tests).

Suitable for Detailed interaction Best for Final Assessment Avoids Superficial distraction.

The most important difference between low fidelity and high fidelity wireframes is how they contribute to the overall user experience. High fidelity wireframes will make sure that your design decisions are communicated to the team building the end product and that target users are accounted for.

Guidelines for Prototyping

1. Just start building. Design Thinking has a bias towards action: that means if you have any uncertainties about what you are trying to achieve, your best bet is to just make something.
2. Don’t spend too much time.
3. Remember what you’re testing for.
4. Build with the user in mind.

Wireframes, mockups and prototypes actually represent the different stages of design flow. Wireframe, a low-fidelity way to present a product, can efficiently outline structures and layouts. Unlike a wireframe,a mockup looks more like a finished product or prototype, but it is not interactive and not clickable.

The definition of a prototype is the original model. An example of a prototype is the first model of a new robot.

Prototyping Model has following six SDLC phases as follow:

1. Step 1: Requirements gathering and analysis. A prototyping model starts with requirement analysis.
2. Step 2: Quick design.
3. Step 3: Build a Prototype.
4. Step 4: Initial user evaluation.
5. Step 5: Refining prototype.
6. Step 6: Implement Product and Maintain.

5 Simple Steps for Creating a New Product Prototype

• Step 1: Start Crafting Your Ideas. Coming up with an idea for your product is one of the most challenging aspects of product design.
• Step 2: Create a Rough Representation of Your Idea.
• Step 3: Create a Physical Prototype.
• Step 4: Refine Your Prototype to Perfection.

There are many avenues you can take at this stage. You may wish to hire professional prototype developers, engineers and designers, but others may be able to help you as well, including a handyman, a machinist or a student from a local industrial design college.

Speak to representatives at companies and check their costs and credentials.

1. Professional designers can be located on free sites such as thomasnet.com.
2. You may also be able to someone who can make your prototype cheaper, such as a student from a local university.

4 Steps to Creating an Effective Product Prototype

1. Design a Concept Sketch. Some of the best ideas begin on napkins!
2. Establish a Virtual Model. Next you’ll want to turn your hand-drawn sketch into a virtual one.
3. Build the Physical Model. Once you’ve approved the virtual rendering, you’ll want to have the actual model built.
4. Find an Experienced Manufacturer.

How to Properly Test a Product Prototype

1. The Usability Factor. Getting strangers to try out your product prototype and allowing a third-party to record their experiences is a great idea.
2. Have Testers Complete Various Tasks With the Prototype.
3. Allow The Prototype Testers to Offer Suggestions.

A good prototype should look real. Clicking buttons, scrolling, anything that can make a prototype look like code. Customers react to magic with ideas.

1. Stand out from the crowd with a memorable brand name.
2. Research brand names in use.
3. Identify three to five product or service characteristics.
4. Identify three to five organizational characteristics.
5. Create buzz words.
6. Envision the brand name.
7. Test possible brand names.
8. Check for availability of use.

The four brand strategies are line extension, brand extension, new brand strategy, and flanker/fight brand strategy.

A strong name is: It should stand out from competitors’ names, as well as from other words in a sentence. This is sometimes called “speech-stream visibility”, the quality that lets the eye or the ear pick out the name as a proper (or capitalized) word instead of a common word.

Essential things a brand name should do:

1. It should be unique and stand out from the competition;
2. It should be easy to pronounce, remember, and identify.
3. It should relate to the product in some way, offering an idea about the purpose, benefits and quality of the products produced by the company.
