The memorandum of understanding (MoU), signed 16 March in Beijing in the presence of visiting King of Saudi Arabia, Salman bin Abdulaziz al Saud, sees WinSun leasing 100 3D printers to Saudi's Al Mobty Contracting Co. with a view to the contractor printing 30 million square meters of housing.

WinSun has committed to sending the printers to Saudi Arabia in the next six months, reports 3D printing news site, 3ders.org.

King Salman officiated at the signing of the MoU between WinSun chairman Ma Yi He and Saudi's Al Mobty Contracting during a four-day visit to China.

WinSun representatives told 3ders.org that its 3D printing technology would cut waste, time and labour, and would use "eco-friendly printing materials".
