Glossary Term
Rapid Prototyping
Definition
Rapid prototyping refers to a set of manufacturing techniques used to quickly fabricate a physical model or prototype of a part, device, or system directly from a digital design file. These processes are typically iterative, allowing designers and engineers to quickly create prototypes, test them, and modify the design before final production. Common rapid prototyping methods include 3D printing, laser cutting, and CNC machining. In the medical device industry, rapid prototyping is used to accelerate the development of new products, enabling faster design iterations, quicker feedback, and more efficient product development.
Relevance to the MedTech Industry
Rapid prototyping can be utilized to reduce the time and cost associated with product development, particularly in complex industries like medical device manufacturing. By allowing teams to quickly turn digital designs into physical prototypes, rapid prototyping facilitates design validation, testing, and iteration before finalizing a product for mass production. This approach improves efficiency, reduces the risk of errors, and supports innovation by enabling faster iteration cycles.

Common Forms of Rapid Prototyping
3D Printing (Additive Manufacturing):
3D printing is one of the most common forms of rapid prototyping. It creates objects layer by layer from a digital model using materials like plastic, metal, or resin. This process is flexible and allows for the rapid production of complex geometries.
Example: A medical device company uses 3D printing to create a prototype of a new pacemaker casing, allowing for quick iterations and testing of different designs.
CNC Machining:
CNC (Computer Numerical Control) machining involves using computer-controlled machines to cut or mill material into a precise shape. It is often used for creating prototypes with high accuracy, especially for metal parts or components that require precise tolerances.
Example: A manufacturer uses CNC machining to create metal prototypes of a surgical tool, ensuring it meets strict dimensional and functional specifications before mass production.
Injection Molding (for Prototypes):
Injection molding can also be used for rapid prototyping, especially for creating parts in plastic or similar materials. This process allows for the creation of prototypes that closely resemble the final product but is typically used for higher-volume production compared to other rapid prototyping methods.
Example: A company developing a new inhaler uses injection molding to create prototype plastic housings that will be used for testing the device's fit, usability, and functionality.
Laser Cutting and Etching:
Laser cutting and etching are used for precision cutting of materials such as plastics, metals, or composites. It is an ideal method for creating flat or sheet-based prototypes or parts that require intricate detail.
Example: Laser cutting is used to create detailed prototypes of a medical device component, such as a membrane or filter, allowing for precise cuts and quick iterations.
