Scaling IoT is about massive amounts of IoT devices deployed, but 3D printing changes the model so the need for molds and tooling can be removed.
Here are some ways 3D Printing is impacting IoT.
Rapid Prototyping is a term of used for years but the impact here can’t be understated. Injection molding to create enclosures and sensor casings can be bypassed, as the printer can cut months from the process of development. It also is a competitive advantage to smaller shops where competing with the resources of a design house needs to be physically demonstrated.
The corollary to this ability is that small batches are economically viable, so small deployments are also viable. This is interesting because, often, with medical devices, the development is iterative. The credit card-sized heart monitor KardiaMobile, in its original form, was the size of a tissue box. Thanks to 3D printing, small volumes of less than a hundred can be economically marketed with on-demand manufacturing.
Metal 3D Printers are another interesting aspect, as rugged industrial sensors or medical grade devices can be developed. This also includes conductive materials, so the sensor itself can be integrated into the form factor.
“3D printing supports a wide range of specialized filaments, including conductive materials, flexible polymers, and high-temperature-resistant composites,” according to a TechBullion article. “These materials allow manufacturers to create complex components with embedded functionality, making them ideal for IoT applications.”
Localized production is another advantage, as the delays associated with supply chains and customs can be avoided. For those who pay attention to sustainability, localization has additional benefits in terms of energy use.
The bottom line is that 3D printing is one more place where hardware innovation is occurring and restoring the advantages of hardware and software integration.
