A Sheffield company says it is on course to become a world leader in the 3D printing industry after raising a further £2.5 million and announcing a partnership with a major global industry player. 

Additive Manufacturing Technologies, whose equipment automates the final stage of the 3D production process, has secured funding from NPIF – Mercia Equity Finance, which is managed by Mercia and part of the Northern Powerhouse Investment Fund; Foresight Williams Technology; the government’s Future Fund; DSM Venturing, the global startup investment arm of Royal DSM; and private investors. 

The latest funding round brings the total raised by the company to date to over £7m and follows its recent success in agreeing a partnership with the tech giant HP, positioning AMT’s technology as a preferred post-processing solution alongside HP’s range of industrial 3D printers.   

AMT’s PostPro technology is a fully automated surface-finishing solution for 3D printed parts. Currently, this cleaning and polishing process has to be carried out by hand and can account for 30 per cent of the cost of a 3D printed part.  

AMT’s technology can not only cut costs but could also make 3D printing viable for high-volume production across industries such as automotive, industrial, medical and sporting goods. 


AMT, which doubled its revenue year-on-year in 2020, was founded in 2017 by Joseph Crabtree and based on technology developed at the University of Sheffield. It now employs over 80 staff at its headquarters in Sheffield, its manufacturing facility in Hungary, and offices in Texas. 

AMT secured a £750,000 investment from NPIF in February 2019 and a further £4.2m later in the year, in a series A funding round led by DSM Venturing and Foresight Williams Technology EIS Fund. The latest investment will allow it to continue its growth and product development plans. 

“Our mission is to be the world’s first-choice application-centric provider of end-to-end industrialized automated post-processing systems. This latest investment will help us to unlock the full potential of industrial additive manufacturing and its sustainable impact,” said AMT CEO Joseph Crabtree.

Nigel Owens of Mercia said: “AMT’s technology is accelerating the adoption of 3D printing and transforming manufacturing in many industries. The company has gone from strength to strength and the recent HP partnership deal is another major milestone, as it represents acceptance of its technology at the highest level. This latest funding is allowing AMT to capitalise on its successes and continue its rapid growth.” 

Ken Cooper at British Business Bank said: “This investment demonstrates how NPIF is able to support high-growth businesses in the North like AMT and unlock additional capital from other investors. As the economy starts to recover we anticipate that the demand for equity finance will increase across north and we are pleased that NPIF will be able to support more innovative, growing companies like AMT.”
