Rapid Prototyping – The Most Comprehensive Guidance
If you’re into the design and architecture field, you probably are aware of rapid prototyping. However, we bring a comprehensive guideline about rapid prototyping for those who aren’t already familiar with the platform. Rapid prototyping services can help to bring significant changes to your business.
When should a company employ rapid prototyping?
Rapid prototyping refers to the process of creating or assembling the physical parts of a model. The fast fabrication procedure is implied into making the design with 3D Computer-aided design (CAD).
This a comprehensive group of techniques that eventually helps in the creation of a scaling model. The additive layer manufacturing technology can play an essential role in constructing the particular part.
Rapid prototyping has brought about several manufacturing technologies. Additive manufacturing is one of the most commonly used rapid prototyping. It may use two different processes- subtractive and compressive.
If the design looks similar to the final product, it is known as a high-fidelity prototype. However, if the final product and prototype reflect a difference, it refers to the low fidelity prototype.
Rapid prototyping history
What was the first rapid prototyping technology to go commercial? The first method for rapid prototyping was introduced back in the 1980s—the initial method catered to creating prototype and model parts. The popularity of application of rapid prototyping became common during 1987 with the coming in on stereolithography technology.
Stereolithography technology refers to a process that leads to the solidification of ultraviolet light-sensitive liquid polymers with laser technology.
Over the years, rapid prototyping measures significantly developed, and different advanced technologies were used for the same. Some of the most common and popular types of rapid prototyping were fused deposition modeling, object manufacturing, and selective laser sintering.
Stratasys was the first to revolutionize the rapid prototyping industry by implementing 3D techniques on the FDM technology in April 1992. Objet launched the first 3D system for rapid prototyping in April 2000. The project was named Polyjet Technology.
Several innovations and improvements have been brought into the rapid prototyping industry to boost mass production capabilities and increase production speed.
Why is rapid prototyping used?
The world is moving at a fast pace, and hence, the technologies are developing too. In times like these, it becomes extremely crucial to adopt measures that can help your business grow. The market competition is increasing.
Hence, businesses need to look out for new and innovative measures for introducing and promoting their products. Rapid prototyping can indeed be one of the best technologies for promoting the market’s products’ popularity.
Rapid prototyping ensures faster development and better innovations. This plays a vital role in ensuring the popularity of your products over that of the customers. Rapid prototyping is a convenient method that is suitable for all types of materials. This versatile technique can further be beneficial for a wide range of applications.
Rapid prototyping often involves highly functional elements that can help to create 3D models. While concept models only give birth to ideas and assumptions about the products, the physical models can play an important role in enhancing the functionality.
Who uses rapid prototyping?
Since the developers get to view the physical model, they will analyze the flaws (if any) and determine how it can benefit them.
The functional prototypes can help developers and manufacturers analyze what the final product would look like. As a result, before moving on to the next stage of production, the developers can easily manage and bring changes in their model if it is required.
The developers have the flexibility to test its function, structure, mobility, and manufacturability. This further helps save a lot of money than restarting the product after any flaw has been detected in the final product.
A workable prototype is extremely beneficial and economically helpful for brands. This helps to maintain a proper balance between functionality and aesthetics. Compared to the development of the final model, a prototype is highly beneficial.
How does rapid prototyping work?
Rapid prototyping follows additive manufacturing technology. The process follows the initial steps of creating a virtual model of the final product before launching it in the market. The CAD software has an essential role to play in the development of prototype models.
Rapid prototyping follows standard data processing and can produce many 3D models within a short time. However, the number of models produced will significantly depend on the number and size of models that are to be produced using a specific type of machine.
The additive layer manufacturing technology of rapid prototyping is created using different technologies such as molding, casting, high-speed machining, and extruding.
In the case of additive manufacturing, different processes play an essential role in building up the prototypes. These two processes are:
Subtractive: Turning, milling, and grinding play an important role in creating a particular form.
Compressive: The semi-solid and liquid material is further altered using different processes like compressive sintering, molding, and casting.
What are the different types of rapid prototyping?
The development in rapid prototyping has only helped to ease technology. This further caters to the different needs. Some of the most common fast prototyping types include the following.
Rapid 3D printing Prototyping
3D printing is one of the most common and known forms of prototyping. The main features of the final model are assembled using additive layer technology or 3D printing. This form is a faster way of achieving desired results for what the final product would look like.
3D printing service is often used to make models in the fields of rapid prototyping manufacturing mold manufacturing and industrial design, and then gradually used in the direct manufacturing of some products.
3D Printing technology is used in rapid prototyping design services, jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other application fields.
Sheet Metal Rapid Prototyping
Sheet metal rapid prototyping is a fast and cost-effective solution for accessing all your important documents. It follows comprehensive procedures like bending, cutting standard gauge, and bending. This helps to create durable end-use metal parts.
The sheet metal rapid prototyping is used for different industries such as energy, robotics, medical devices, automotive, and aerospace. The sheet metal used for rapid prototyping has a thickness of 0.006 inches to 0.25 inches.
CNC Rapid Prototyping
CNC Rapid prototyping provides the benefit of using computerized equipment for better-engineered models and fast-turnaround of the prototypes. This plays an important role in creating high-quality end-use materials.
Compared to other prototyping processes, CNC rapid prototyping is fast and can play an important role in designing even the most complex elements in the simplest ways.
CNC rapid prototyping may use different procedures like plastic injection molding and pressure die casting to create the actual element. In many cases, it will pave the way to create rigid metals in a standard form.
Moreover, the models developed using CNC rapid prototyping are easy to alter or modify. This procedure works with different materials, thereby providing extensive benefits in the long run.
Rapid Injection Molding Prototyping
With the help of rapid Injection molding, prototypes of injection modeled parts are created. The thermoplastic resin allows the creation of these modeled parts within 2-5 weeks.
One of the most significant benefits of rapid injection molding prototyping is creating prototype models using different materials and colors. This further plays an important role in maintaining flexibility through the molds.
The CNC machines usually help in the creation of rapid injection molding prototyping. The process also follows a bridge-to-production method which can allow creating thousands of parts.
