What Is Rapid Manufacturing?
Rapid manufacturing entails various methods for fast production of customized parts, whole parts, low-volume machining runs, or bridge production. This manufacturing approach allows manufacturers to create simple to very complex parts and products for less and with reduced cycle time since it relies heavily on modern technology and software automation.
Rapid manufacturing encourages efficient, cost-effective, and faster delivery of finished products. It presents the means to reshape the manufacturing landscape with a promising future due to its ability to allow customized solutions and accelerate production processes.
Rapid Manufacturing vs. Additive Manufacturing
Rapid manufacturing and additive manufacturing are often codependent. Product designers in different industries can easily create customized items with additive manufacturing technology using a CAD model. The 3D printing technology works by adding multiple layers in consecutive order until the desired product is achieved. It produces a prototype or fully functioning product that can be shipped to customers or examined for progressive redesigns and further prototyping processes.
Additive manufacturing is compatible with a long list of materials, even though it is famous for manufacturing metals and plastic-based parts and components. This technology enables designers and engineers to produce highly complex designs that would have been extremely expensive with conventional manufacturing techniques. Additive manufacturing is an ideal choice for different types of engineering since it helps reduce overall costs than conventional manufacturing. It is a popular means of engaging in speedy prototyping.
Rapid Manufacturing vs. Traditional Manufacturing
Rapid manufacturing is different from traditional manufacturing in terms of cost and time. Traditional manufacturing techniques are primarily outdated and can take longer time to finish. Consequently, it can be a significant setback for businesses that focus on delivering top-notch products to their customers on time, preferably faster than their competitors.
In addition, businesses involved in prototyping need their test products made and delivered to their company for progressive prototyping and redesigning in a time-efficient manner. Rapid manufacturing embraces new technologies that make the production process much faster.
In the aspect of cost, rapid manufacturing and conventional manufacturing differ. The materials used for rapid manufacturing cost less and require less labor than traditional manufacturing, which requires a substantial workforce to execute the operation. Likewise, maintenance costs of older machinery can significantly affect overall production costs.
Although rapid manufacturing was used exclusively for prototyping in the past, it became the norm as the manufacturing landscape evolved and embraced more technologically advanced machines and tools. Rapid engineering is cost-effective, efficient, and quick in producing whole-end products and parts.
However, it would help to note that rapid and conventional manufacturing can be integrated depending on the specific application. While rapid manufacturing is ideal for prototyping, custom parts, and small-scale production runs, traditional manufacturing can sometimes be suitable for high-volume production runs.
Rapid Manufacturing vs. Rapid Prototyping
Rapid prototyping is a specialized product development process for producing high-quality physical models of 3D CAD design. It enables the product creation and iteration for evaluation and testing. A prototype is a critical basis for engineering testing and is helpful in the product design development and improvement stages.
Rapid manufacturing and rapid prototyping are not entirely different because rapid manufacturing is utilized for the process of rapid prototyping. Rapid manufacturing was reserved for prototyping at its first inception. However, it is now a widely embraced process for making prototypes, whole end-user parts, and customized products.
Rapid prototyping is beneficial for startups and businesses that consistently develop and redesign their products. This prototyping approach involves creating prototypes with CAD data. Its time-efficiency allows seamless product revisions and redesigns. Several companies rely heavily on this rapid prototyping to work with cheaper, sturdy materials to continuously create prototypes for test and experiment purposes. More importantly, rapid prototyping facilitates an excellent turnaround time for finished products.
Common Rapid Manufacturing Process
Rapid manufacturing encompasses different processes, each with unique procedures and results. These include:
3D Printing
3D printing is a versatile additive manufacturing process that produce parts by melting and restructuring thermoplastic filaments with a printing device. It lays one material layer over another from top to bottom until the desired product is achieved.
3D printing (additive manufacturing) is a rapid production process involving different plastics, including PLA, ABS, and other thermoplastic blends. However, there are types of 3D printers that are compatible with metals. Fused Deposition Modeling, Stereolithography (SLA), Selective Laser Melting (SLM), and Selective Laser Sintering (SLS) are typical types of 3D printing technologies.
CNC Machining
This manufacturing employs the latest technology to help businesses achieve their manufacturing needs. CNC machining allows for the efficient production of high-quality, precise parts with the aid of software automation. CNC machining involves shaping a bar stock material with CNC tools through milling, turning, grinding, and drilling operations. Computer numerical control tools are the common name for all the tools used in CNC machining processes to shape raw materials into desired shapes and add different features.
CNC machining is compatible with various materials, including metals, plastics, wood, glass, composites, etc. Laser cutting is a renowned CNC machining process known for its ability to make precise cuts on hard materials. Machinists often use CNC milling machines and water jet laser cutters for precision CNC machining operations.
Metal Fabrication
This rapid manufacturing method utilizes automated cutting, welding, and machining processes to create strong and durable parts from different metals. It is suitable for producing small functioning components of an assembly and heavy-duty products for various applications.
Injection Molding
Injection molding allows manufacturers to produce components in high volumes. This technology is suitable for repeatedly producing the same parts using molds. It can produce hundreds, thousands, or millions of identical parts with relatively simple designs.
The injection molding technique involves heating plastic or metal until it changes to a hot liquid form. Then, the machine nozzle is inserted into the created molds for the intended product, where the material injects the molten metal or plastic, allowing it to take the mold’s form.
Choosing Between the Different Rapid Manufacturing Technologies
One of the most critical considerations in rapid manufacturing is choosing the ideal process for your project from the different rapid manufacturing processes. It is imperative that you make this decision with your product design team to ensure a successful rapid manufacturing operation. However, you will eventually have to choose between 3D printing, CNC machining, metal fabrication, and injection molding, the most used manufacturing processes.
If a relatively small amount of sturdy metal parts with precise dimensions and surface finish is what you need, CNC machining is the perfect manufacturing process for you. Alternatively, 3D printing is ideal for making plastic parts with any form of internal framed or latticed patterns.
With injection molding, rapid manufacturing is perfect for handling large-scale production runs. Particularly when you must produce one single part with a less complex design a million times, it offers flexibility and a cost-effective advantage for your business.
Metal fabrication is less flexible than the processes discussed above. However, metal fabrication through rapid manufacturing can only be used to produce custom-fabricated metal items, even though it is suitable for mass production of different parts and components.
Advantages of Rapid Manufacturing
Rapid manufacturing offers a wide range of benefits, including:
Time and Cost-Efficiencies
Rapid manufacturing allows manufacturers to repeatedly design and introduce new changes for testing phases of new products with ease and speed. This benefit is critical to product development for emerging businesses with very narrow deadlines.
