WP1. Synthesis and Characterisation

The objectives of WP1 are:

• Specifications formalisation
• Tuning of the optimal composition for the intermediate coating layer.
• Tuning of the optimal composition for the trabecular-like coating
• Technological transfer of the glass composition to the industrial scale

For the realization of this work package, its structure includes four tasks:

Task 1.1 Literature search and market analysis
Task 1.2 Glass to coat the ceramic cup
Task 1.3 Glass for the trabecular-like coating
Task 1.4 Pre-industrial batches for biomedical application


WP2. Modeling

The main objective of WP2 is to create and develop virtual models with the aim to investigate mechanical properties of new material data both for coating adhesion (T2.1) and the trabecular part (T2.2).

The virtual models replicate physical behaviour of the real component, so they can usefully simulate mechanical and thermal properties of materials. In addition new material laws can be implemented with dedicated software routines that will be validated by experimental data and micro-CT results.

This work package is split into two tasks:

Task 2.1 Virtual simulation of coating adhesion
Task 2.2 Virtual simulation of the trabecular-like coating adhesion

WP3. Cup prototypes

The WP3 aims at the following four goals:

• To explore the use of subtractive manufacturing technology combined with laser ablation for the manufacture of multilayer ceramic cups
• To define an integrated methodology for the manufacturing process of multilayer ceramic cups taking into account all the sustainability dimensions
• To implement pilot tests for the new manufacturing processes explored so to assess the results of the solutions proposed and to enhance the transfer of results to the SMEs
• To study the laser ablation process applied to surface modification of ceramic materials testing different micro-geometries on ceramic cups

The realization of this work package encompasses three tasks:

Task 3.1 Alumina cup preparation (subtractive methodology)
Task 3.2 Cup surface modification (laser ablation)
Task 3.3 Cup characterisation and process formalization


WP4. Dense intermediate coatings

The WP4 pursues two objectives:

• Realisation of well adherent, crack free coatings on the ceramic cup prototypes of WP3.
Different techniques will be applied in order to identify the most suitable and inexpensive one focusing on the transfer to the production line.
• Mechanical and structural investigation of the produced dense coatings.

In order to do so, the work to be done in this WP is divided into the following three tasks:

Task 4.1 Cup coatings through airbursh
Task 4.2 Coating techniques alternative to airbrushing
Task 4.3 Coatings characterization

WP5. Cup with trabecular-like coating

The main goal considered for this WP to produce and characterise prototypes of MONOBLOCK acetabular cups.

In order to achieve this, two different fabrication techniques will be proposed and theiri ndustrialisation will be studied:

- The sponge replication method (POLITO)
- The laser sintering technique (AIMEN)

For the execution of this WP, three tasks are considered:

Task 5.1 Trabecular-like coating with sponge replication method
Task 5.2 Rapid prototyping of the trabecular-like coating
Task 5.3 Characterisation of the trabecular-like coating


WP6. Demonstrator

This work package is focused on the demonstrators of the project. Concretely, the aim of this WP is triple:

• To ESTABLISH THE SET UP of industrial production of homogeneous and heavy metal free glass batches on the basis of WP1 results
• To VALIDATE the virtual models developed in WP2
• To FORMALIZE the processing parameters for monoblock cup prototype production

The work to be done in this WP includes three tasks:

Task 6.1 Industrial batches for biomedical application
Task 6.2 Validation of the virtual models
Task 6.3 Setting of the processing parameters

WP7. Dissemination

In this work package lie the dissemination of the project results (publications, workshops) and the managing of their intellectual property. The objectives of WP7 cover:

• IPR related issues will be defined within the Consortium Agreement
• Custom-training for SMEs employees and dissemination events for SMEs
• Publications in international scientific Journals with high IF, conferences and third level seminars
• Diploma theses for Biomedical and Mechanical Engineers
• Final Report on dissemination activities

The work conceived in the frame of this WP includes the following tasks:

Task 7.1 IPR issues
Task 7.2 Publications and dissertations
Task 7.3 Training

WP8. Management

This work package is focused on the issues related to the coordination and management of the consortium members and results. The objectives of WP8 are:

• Programming, supervision, evaluation and interfacing the Commission for all administrative and financial aspects related to the project
• Co-ordinating the project activities, for punctual delivery of reports and outcomes and for getting all the deliverables
• Establishing the necessary infrastructure (monitoring mechanism, circulation of guidelines, analytical accounting systems) for the project administration
• Supporting the evolution of the workplans (time-plan of the tasks, critical tasks, contingency plans)
• Supporting the meetings of the project's committees (preparation, agenda, support during the meetings, circulation of minutes, presentations and proceedings)
• Handling the financial aspects of the project
• Organization of project meetings

The project will be coordinated by POLITO, which will be in charge of activity of programming, supervision, evaluation and interfacing the Commission and for all administrative and financial aspects related to the project.

The following tasks are considered inside WP8:

Task 8.1 Kick off meeting
Task 8.2 Meeting and reports
Task 8.3 Final meeting and reports
