Rapid prototyping is a
group of processes and techniques used to fabricate a physical model of end
parts using 3D CAD data. It is a quick way to transform an idea into a
successful prototype before starting the final production of any physical part
or assembly. It is an essential stage of the product development process in any
manufacturing industry to create a concept model and validate the details for an
accurate representation of the finished product. Rapid Prototyping is used in a
wide range of applications and industries.
Typically, rapid prototyping employs a range of methods to visually and functionally evaluate and validate an engineering product design. The process of creating a 3D scale model of any assembly part involves various stages to create an actual replica of the final product. The most common stages of rapid prototyping include concept visualization, prototype design, review, validation, and refinement to design a concept model. The cost of rapid prototyping services depends on various factors such as volume, height, orientation, material, and finish depending on the industrial requirements.
Types of Rapid Prototyping Techniques:
Different industries use different technologies to fabricate a 3D scale model quickly and effectively. Depending on the industrial use and application, choosing the right technology is critical for successful prototype fabrication. Engineering product designers use the following technologies for rapid prototyping:
· CNC Machining Prototyping
· Stereolithography (SLA)
· Selective Laser Sintering (SLS)
· Selective Laser Melting (SLM)
· Direct Metal Laser Sintering (DMLS)
· Vacuum Casting
· Fused Deposition Modelling (FDM)
· Digital Light Processing (DLP)
· Binder Jet 3D Printing
Rapid Prototyping is also referred to as 3D printing to fabricate a physical design from a virtual design using computer aided design (CAD) software and other manufacturing technologies. Prototype engineers use more than one technique to assemble a 3D scale model during the prototype manufacturing process. In Rapid Prototyping, CAD data translates to the 3D prototyping machine to fabricate the final prototype based on a standard data interface.
Advantages of Rapid Prototyping:
Rapid prototyping has various industrial advantages in any engineering product manufacturing process. Some of the most attractive advantages are:
· Reduced design and development time
· Overall lower product development cost
· Eliminate design and functional error at early stages
· Enables virtual and functional testing
· Test more solutions and incorporate changes quickly
· Reduced material wastage
· Minimize design flaws
· Allows customize product design using CAD software
Rapid prototyping services are used in a wide range of applications across various industries such as automotive, medical, and aerospace to fabricate a 3D scale model of assembly pars. It is a time and cost-effective process to transform an idea into an actual product effectively in quick time. If you are looking for product prototyping services, try to find a company with years of experience in the industry using different technologies and tools to create an accurate prototype model as per the client’s requirements.
