Missions

The Centre national de la recherche scientifique (CNRS) is looking for a full-time post-doctoral fellow at the G-SCOP laboratory located in Grenoble, France, to contribute to the FUI Ambition project. In the context of metallic additive manufacturing, he/she will develop design rules for additive manufacturing adapted to the copper material. He/she will integrate the manufacturing constraints identified on the prototype parts, in particular on Electron Beam Melting (EBM) technology and possibly on powder bed technologies with laser energy source. He/she will define the rules for the nesting and support of the most appropriate parts. The part design rules will allow to obtain the best precision, surface finish, desired characteristics or productivity according to the elementary geometrical shapes of the part. He/she will implement the products designed on the EBM resources of the laboratory. He/she will work in cooperation with the other post-doctoral student recruited on the project.
The main application will focus on the needs of one of the industrial partners of the Ambition project, a designer of solutions for energy distribution. This partner expects from the project the development of high energy efficient switchgear and electrical equipment exploiting the new design possibilities resulting from the manufacturing freedom offered by additive manufacturing. The connections of the equipment, various technical parts of the line "conducting" the electric current will be topologically optimized.
Combinations of functions will be possible (e.g. part combining the function of electrical conductor and heat sink) aiming to reduce losses due to heating by Joule effect.
Technical functions such as the support of the electric arc contact can be optimized in order to reduce the amount of copper used.
The long-term objective is to reduce development and qualification times for copper conductive parts of apparatus and equipment by the possibility of extremely rapid functional prototyping of complex parts. This possibility exists for many materials and is to be developed for Copper, the most widely used material for conducting electric current.

Activities

- Collect the manufacturing constraints identified by the project partners
- Elaborate the specifications of the parts to be designed with the partners
- Develop topological optimizations including combinations of functions envisaged
- Propose design rules
- Disseminate results through publications and presentations at national and international conferences
- Compile, write and present the results of research studies to internal or external stakeholders

Skills

- Experience and training in the field of powder bed metal additive manufacturing.
- Skills in mechanical dimensioning
- Skills in the field of topological optimization
- Competence in CAD tools
- Very good oral and written communication skills
- Ability to establish and maintain strong professional relationships
- Ability to achieve defined results and objectives
- Good organizational and project management skills
- Good adaptability

Work Context

The G-SCOP laboratory is a “Unité Mixte de Recherche” under the joint supervision of the CNRS, the University of Grenoble Alpes and Grenoble INP (UMR5272). It is located in Grenoble, France. It is a laboratory of about 170 people, including 60 researchers and teacher-researchers.
G-SCOP is a multi-disciplinary research laboratory responding to the challenges of design, optimization and management of products and production systems. The research carried out covers the entire life cycle of a product or product/service, from its creation to its end of life through the phases of design, production, distribution, use and then recycling, reuse or destruction. G-SCOP addresses the challenges posed by changes in the industrial world through research conducted in Flow Management and Integrated Product Design, based on a cross-disciplinary expertise in Industrial Information Systems and Optimization Methods, both in their final and fundamental versions.
In the field of additive manufacturing (AM), the skills of the G-SCOP laboratory concern the methodologies and rules of part design for AM, the CAD-CAM digital chain for AM, and the thermal simulation of the process. Its know-how in part design makes it essential to take full advantage of the methods that will be developed in the project for part optimization.
G-SCOP, with SIMAP, is the only French research laboratory with EBM additive manufacturing means. It develops around this process a recognized competence in the field of part design, topological optimization and lattice structures, the CAD/CAM numerical chain for the FA and the thermal simulation of the process.
Grenoble is a town in the south-east of France in a conurbation of about 500,000 inhabitants in the Auvergne-Rhône-Alpes region. It is located in the heart of the French Alps.
