BOFA International, Ltd, a global fume and dust extraction solutions provider headquartered in Poole, Dorset, UK, is redesigning and improving its 3D PrintPRO 4 technology, offering wider filtration airflow ranges and expanded filtration capacity. The enhanced 3D PrintPRO 4 is an industrial machine that is suitable for larger manufacturing processes including including Material Extrusion (MEX) processes such as Fused Filament Fabrication (FFF), Powder Bed Fusion (PBF), Vat Photopolymerisation (VPP), digital light processing, Binder Jetting (BJT) and material jetting.

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

Airflow rates of 5 m3/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 AM machines, including large format machines.

Operating pressures in the new 3D PrintPRO 4 have been tripled to 96 mBar, which allows the unit to overcome greater system resistance, reportedly enabling effective performance in complex installations and multiple AM machine 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, stated “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 filtration system options for this market are improving all the time, underlining our leading position in meeting the needs of companies investing in the benefits of industrial Additive Manufacturing processes.”

The company will showcase the new technology at Formnext 2021.
