Structured and Freeform Surfaces play an increasingly important role in many technology advancements ranging from optics to biomedical and energy applications. The functional characteristics of such surfaces supersede those of “traditional” surfaces, thus opening research and development avenues and new challenges for their specification, fabrication, measurement and verification.

The next euspen Special Interest Group (SIG) on Structured and Freeform Surfaces meeting will bring together researchers and practitioners from academia, industry and government agencies to discuss state-of-the-art practice, and key research and development in the area of precision engineering associated with structured and freeform surfaces. The meeting includes keynote presentations, oral sessions, posters and training seminars covering the newest developments and research on structured and freeform surfaces.

The local hosts and organizing committee for the Special Interest Group meeting on Structured Freeform Surfaces are :- Prof. Richard Leach from University of Nottingham; John Schaefer and Alexander Sohn from ASPE; Dr. Zhen Tong from University of Huddersfield;  Dr. Uwe Brand from PTB; Prof. Guido Tosello from DTU and Prof. Benny Cheung from ASPEN

The Structured Freeform Surfaces meeting chair is Prof. Richard Leach from University of Nottingham

A special focus will be given to research fields in the following topics:

Replication Techniques

  • Surface functionalisation
  • Replication processes (moulding, imprinting, embossing, …)
  • 3D micro-additive manufacturing technologies
  • Replication assessment and tolerance verification

Structured Surfaces to Affect Function

  • Structured surfaces characterization, combining structured and freeform geometries
  • Functionality and structure (tribology, biology, …)
  • Manufacturing and measurement (in-line, in-situ), process control
  • Dimensional metrology for structured surfaces

Precision Freeform Surfaces 

  • Freeform surface characterisation
  • Functionality and topography (optics, aeronautics, …)
  • Manufacturing and measurement (in-line, in-situ), process control
  • Dimensional metrology for freeform surfaces

A special focus will be given to research fields in the following topics:

Large-Scale Surface Structuring

  • Microstructures on large-scale surfaces (rigid and non-rigid)
  • Roll-to-roll patterning and structuring
  • Manufacturing and measurement (in-line, in-situ), process control
  • Dimensional metrology for large-scale surfaces

Surfaces for Nanomanufacturing and Metrology 

  • Nano-structured and functionalised surface characterisation
  • Nanomanufacturing processes (substractive, additive, formative)
  • Measurement and evaluation of nano-structured surfaces
  • Dimensional metrology at of nanoscale surfaces and structures

Submission of abstracts

Abstracts are expected to describe original work, previously unpublished and should indicate new and significant advances and their importance. Initially short abstracts comprising of approx. 300 words in length should be submitted online using the below links.

Following review a review of submitted abstracts, authors will be notified of acceptance of presentation mode (poster/oral).

The invitation to submit an abstract does not constitute an offer to pay travel, accommodation or registration costs associated with the conference. Similarly, no speaker fee is paid to successful participants. All speakers must register for the conference and transfer registration fee. In specific cases the organising committee reserves the right to deviate from the standard procedure.

Submission deadline: 13th July 2020
