BOFA extends 3D print extraction and filtration performance

BOFA International is enhancing value for the 3D print sector by redesigning and improving its 3D PrintPRO 4 technology, offering wider fume extraction airflow ranges and expanded filtration capacity.

The enhanced 3D PrintPRO 4 is an industrial machine that is suitable for larger manufacturing processes which involve polymer VAT polymerisation or polymer fused filament fabrication.

The upgraded unit has advanced multi-stage gas filtration, with a deeper carbon bed to capture a greater volume of potentially harmful fume, thereby extending filter life and ensuring safe, odourless printing for longer. This is complemented by a larger HEPA filter, enabling multiple 3D printers to be hooked up to a single BOFA unit, optimising investment in extraction technology to help keep workplaces free from airborne contaminants and equipment clear of particulate residue.

Airflow rates of 175 cu ft/min in the upgraded technology are double that of the original 3D PrintPRO 4, enabling the unit to cater for a greater range of industrial 3D printers, including large format printers.

Operating pressures in the new 3D PrintPRO 4 have been tripled to 96mBar, allowing the unit to overcome greater system resistance, ensuring effective performance in complex installations and multiple printer architectures. The redesigned 3D PrintPRO 4 has been tested to UKCA and CE as well as UL and cUL standards.. .

Haydn Knight, Sales & Marketing Director at BOFA, said: “The 3D printing market is evolving at a rapid pace and the enhancements to our 3D PrintPRO range match the industry trend towards faster printing capability and larger build chambers.

“Our fume extraction system options for this market are improving all the time, underlining our leadership position in meeting the needs of companies investing in the benefits of industrial additive manufacturing processes.”
