Title

High Speed Sintering: A low cost, high volume Additive Manufacturing technology

Abstract

High Speed Sintering (HSS) is an Additive Manufacturing technology originally invented in 2003 with a focus on enabling low cost and high volume part production.  The technology is a powder bed sintering approach suited to a wide variety of thermoplastic polymers.  The key to the approach has been the novel use of inkjet technology to print infra-red absorbing fluid to the powder bed surface enabling a number of benefits over pre-existing approaches; these benefits include faster throughput, low part cost, wider range of materials and improved mechanical properties.
This talk will explain how the technology was first invented and developed in academia with assistance from government funds.  The technology itself will be introduced in detail, explaining its strengths and weaknesses.   Finally, routes to commercial exploitation of the technology will be described.

Biography

Neil spent 20 years in academia conducting research in the field of Additive Manufacturing. He has been a pioneer of the technology as a manufacturing process, publishing the first work proposing the use of "3D Printing" for series manufacture and being the lead editor on the world’s first book into the subject.
The majority of Neil’s research has been into manufacturing process/material aspects and this has led to him being an inventor on three patent families.  By 2016 he had secured over £5M of cash from public sources and industry. His inventions have been licensed widely, earning substantial royalties.  
In 2016 Neil became Director of 3D Printing at Cambridge based inkjet printhead manufacturer Xaar where his role is to build a 3D Printing business utilising Xaar’s world leading piezo-electric inkjet printing technology across a range of 3D Printing technologies including one of his own invention, High Speed Sintering.
