CAMS2021 Seminar Series: 1
08 October 2021 | 10am AEDT
'Fused filament fabrication of composite materials' by Antonella Sola
CAMS2021 is part of an ongoing series of meetings that are the product of the cooperation between two eminent materials professional societies in Australia – Materials Australia (MA) and the Australian Ceramic Society (ACS).
This year the 7th conference of the Combined Australian Materials Societies (CAMS2021) was to be hosted in Melbourne, Australia in December. However, the present situation in Australia has forced the organising committee to postpone this event to 02-04 February 2022.
In place, the organising committee offers members of these two societies and those already registered for CAMS2021 the opportunity to attend a seminar series where prominent international researchers will present their latest research results to the Australian material research communities.
This seminar series will take place over several weeks between October and December and will be a live, online-only (zoom) event for members of the two societies, featuring invited lectures from international researchers, and it will not be recorded.
You must be a member of Materials Australia or the Australian Ceramic Society, have registered for CAMS2021 (or submitted an abstract) to attend these seminars.

Speaker Details
Antonella Sola is presently the Science Leader in Active Materials for the Manufacturing Business Unit at the Commonwealth Scientific and Industrial Research Organization (CSIRO – Clayton). With 20 years of experience in research, she has been working on composites, advanced coatings and biomaterials. In her role as Science Leader, she is investigating additive manufacturing and new processing technologies for the obtainment of composite systems and active materials with improved functionality. She is currently launching the new Fused Filament Fabrication Facility (4F) for the development of bespoke filaments for 3D printing by fused filament fabrication.
Abstract
The fused filament fabrication (FFF) technique, also known under the tradename of fused deposition modeling (FDM), is one of the most popular additive manufacturing processes, with an ever-growing number of diverse applications in Future Industries such as Aerospace, Biomed, Security and Defence.
FFF was originally conceived to process thermoplastic materials, but the limited functionality of commodity thermoplastics often confines the usage of this technique to print conceptual prototypes. Adding an appropriate filler plays a key role to provide the polymer matrix with new properties that can be tailored to match the assigned service requirements yielding functional active materials.
As a further advancement, FFF can be extended to achieve fully inorganic parts. To this aim, a composite filament with a very high filler loading is fed into the printer to fabricate the green part (“shaping”). Afterwards, the polymer matrix that acts as a sacrificial binder during the printing step is removed under controlled conditions (“debinding”) and the green part is sintered to obtain a fully inorganic part (“sintering” – SDS process).
After introducing the basics of FFF, the seminar will discuss the opportunities created by the uptake of new composite feedstocks, as well as the technological challenges observed upon printing due to the presence of a filler.
