Superior insulation properties in elevated temperatures

High-performance polymers offer extreme electrical insulation properties at remarkably high, up to 250°C temperatures. This enables completely new applications, where the lightness of the polymer combined with excellent insulation properties is utilized. As the transport industry electrifies, 3D printing high-performance polymers can offer lightweight, safe, and cost-effective solutions for all vehicle manufacturing.

With 3D printing in electronics, the most complex housings and protective cases can be manufactured using these high-performance materials. For example, such an application could be housing for an electrical motor to ensure the user's safety or a mounting bracket that needs to be customized by the shape of a circuit board.

Protect your electronics with high-performance materials

High-performance ESD materials enable the manufacturing of jigs and fixtures in environments where traditional engineering plastics are insufficient. 3D printing in electronics enables cost-effective and fast manufacturing.

Electrical components are crucial parts of many machines and devices. Therefore, it’s essential to protect the electronics in all environments to prevent malfunctions. One of the aspects that the electronics might need to be protected from is static discharges. With ESD safe materials, the static discharge can be minimized, and the safety of the electrical component can be ensured. When there are also other aspects such as elevated temperatures, radiation, or chemicals that the electronics need to be protected against, high-performance polymers provide the possibility to do so.

Sealed electronics inside assemblies

When electrical components like sensors, drivers, or wiring are placed under harsh conditions such as continuous movement, impacts, or chemicals, their life expectancy is usually not ideal. By 3D printing in electronics, these components can be integrated into the structure of a part. When wiring or a sensor is sealed inside the part, it’s protected from these external factors and corrosion. This opens new possibilities in the placing of the electronic and makes modular assemblies available.

One example of such an integrated application could be an assembly where an inductive sensor is sealed inside a high-performance polymer part that protects the sensor from external impacts but allows it to identify desired metal objects.

3D printing in electronics with miniFactory Ultra 3D printer

  • Corrosion in the housings of electronics is quite a common issue. Eventually, the corrosion will start to affect the electronics as well. Therefore, printing these housings with high-performance polymers that are corrosion-free solves such issues.
  • Extreme electrical insulation properties at elevated temperatures can be achieved with 3D printed high-performance polymers.
  • ESD safe components for harsh conditions such as space applications can be manufactured with the miniFactory Ultra 3D printer.
