Using the same commercial-grade 3D printing process and material for both prototyping and fabrication can positively impact the way products are developed and brought to market.
Avid’s ongoing business relationship with CGX, a manufacturer of complex electroencephalogram (EEG) devices, demonstrates the advantages of utilizing 3D printing for both product development and production.
From Concept to Production
With production volumes fewer than 1,000 units annually and a relatively high unit cost ($20,000 and up), CQX’s EEG devices were ideal for additive manufacturing. For prototypes and production of the Quick-20r EEG headset, CGX turned to the 3D printing services at Avid Product Development. Both prototyping and manufacturing utilized Avid’s industrial HP Multi Jet Fusion 3D Printing solutions in PA11 material.
After developing and testing multiple iterations, the final design of the CGX Quick-20r headset exemplifies one of the benefits of design for additive manufacturing- part consolidation. Combining 80 unique parts into 30, the headset features 19 “pods” that house EEG sensors and contact a person’s head to capture brain activity. Unlike traditional EEG headsets which are challenging to set up and uncomfortable to wear, the CGX Quick-20r headset3 features adjustable pods with three degrees-of freedom, a feature that would have otherwise required assembly. With AM, the pods are preassembled digitally and 3D printed.
According to Ira Friedman, president of CGX, using Avid’s Multi Jet Fusion 3D printing services for both prototyping and manufacturing eliminated the need for extensive upfront capital to injection mold 200 individual parts.
