BOFA introduces new filter technology for 3D printing at high temperatures

BOFA strengthens its position as the market leader in portable fume and particle filtration systems for additive manufacturing with its latest generation of 3D PrintPRO technology, designed specifically for high-temperature processes.

The new model, 3D PrintPRO HT, filters particles, gases and nanoparticles emitted during the processing of polymers in print chambers at temperatures of up to 100°C. It is particularly suitable for processes such as fused deposition modeling, stereolithography and digital light processing. This performance is achieved through the use of advanced electronics, thermal insulation, a highly insulated connection kit, intelligent airflow management and advanced filter architecture. This ensures energy-efficient extraction of emissions with low heat loss in environments with higher chamber temperatures.

The modular design of the 3D PrintPRO HT makes it ideal for closed continuous operation, with a maximum airflow rate of up to 100 m³/h to filter particles during the printing process. There is also an open intermittent operation (purge cycle) with a fixed airflow of 30 m³/h, which filters both particles and gases. Both requirements can be met by a connection kit. The technology also has filter change indicators and integrated filter status communication with the host machine.

Arran Morgan, Senior Product Manager at BOFA commented: “This latest generation of our 3D PrintPRO HT system demonstrates how BOFA is reflecting a constantly evolving additive manufacturing marketplace. It means that manufacturers are able to benefit from working high-performance polymers that require elevated chamber temperatures, while helping safeguard both the workplace atmosphere and their investment in expensive equipment through portable extraction.”
