Impact Story

Taking two bites of the research pie
Summary
Partnerships between industry and researchers can often be seen as the holy grail of product development. Combing the minds of academics with the directed knowledge of manufactures sounds great, but in practice can break down over issues such as project direction, ip owership and the final stumbling block of commercialisation. One partnership that have overcome this and is on its way to market, is the collaboration between researchers from a consortium of universities and Australian dental restorative materials manufacturer SDI Ltd.

Impact Story

Taking two bites of the research pie
Summary
Partnerships between industry and researchers can often be seen as the holy grail of product development. Combing the minds of academics with the directed knowledge of manufactures sounds great, but in practice can break down over issues such as project direction, ip owership and the final stumbling block of commercialisation. One partnership that have overcome this and is on its way to market, is the collaboration between researchers from a consortium of universities and Australian dental restorative materials manufacturer SDI Ltd.
