The subtractive manufacturing process involves etching, drilling, or cutting from a solid board to build the final product. It is ideal for applications using a wide variety of materials and in the PCB fabrication of large-size products. In the additive manufacturing process, a product is developed by adding material one layer at a time and bonding the layers together until the final product is ready. The ability to control material density and the possibility of including intricate features makes this process versatile. It is used in a range of engineering and manufacturing applications, especially in custom manufacturing.
Benefits of 3D printing in medical device manufacturing.
3D printing is economical and offers quick PCB prototyping without the need for complex manufacturing steps. It optimizes the PCB design process by avoiding possible design faults in the initial PCB design stages. 3D printing is easy on flex PCBs and multilayer PCB printing is possible using the latest design software. With the growing manufacturing trends and improving software, 3D printing will be more than a prototyping tool and can be a viable alternative for production parts. 3D printing has been recently used for the end-part manufacturing of several medical devices like hearing aids, dental implants, and more. It is more beneficial for low-volume productions.
