Project ImpPro3D

Project ImpPro3 is a study project of the Ecole Centrale de Lille. We want to create an open source 3D printer, with the possibility for the user to choose each printing critical parameters (printing head velocity, polymer thoughtput, etc...). This acquired freedom will be a powerful research lever for the 3D printing world and it correspond with a real demand from the academic world.

The project is currently realized in partnership with the Laboratoire de Mécanique de Lille and Mr QUAEGEBEUR, lecturer and researcher at the laboratory LML.

Our project is online on the RepRapWiki and also on the "Centraliens de Lille" wiki.

The Prototype

Our prototype is inspired by the MENDEL one from RepRap project. The mechanical structure of the printer is already completed. However the command, regulation and user safety elements are in development.

To learn more about :

  • Material part : main body of the printer, electronics, sensors, etc... See here.
  • Computer software part : all the softwares used by ImpPro3D are here.

Scheduled duration of the project : 4 semesters
Concerned subjects : Computer software/Microcomputing, Programming, Automation, Mechanics, Electronics.

Open Source

Voici un extrait d'un article Wikipédia :

"In production and development, open source as a development model promotes a) universal access via free license to a product's design or blueprint, and b) universal redistribution of that design or blueprint, including subsequent improvements to it by anyone. Before the phrase open source became widely adopted, developers and producers used a variety of terms for the concept; open source gained hold with the rise of the Internet, and the attendant need for massive retooling of the computing source code. Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities.The open-source software movement arose to clarify the environment that the new copyright, licensing, domain, and consumer issues created.

Generally, open source refers to a computer program in which the source code is available to the general public for use and/or modification from its original design. Open-source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community. Open source sprouted in the technological community as a response to proprietary software owned by corporations.

The open-source model includes the concept of concurrent yet different agendas and differing approaches in production, in contrast with more centralized models of development such as those typically used in commercial software companies. A main principle and practice of open-source software development is peer production by bartering and collaboration, with the end-product, source-material, "blueprints", and documentation available at no cost to the public. This model is also used for the development of open-source-appropriate technologies, solar photovoltaic technology and open-source drug discovery.", Wikipedia, http://goo.gl/PmFwEh

Because our project is Open Source, we have to put our printer's datas online. A dedicated wiki is already created (RepRapWiki) and a software hosting plateform "GitHub" allows us to access to many different software source code.

Ecole Centrale de Lille

Member of the "Groupe des Écoles Centrales", the École Centrale de Lille is one the french "Grande école" engineering school dated since 1854. It grants three engineering diplomas :
  • General engineer, in 3 years, after "classes préparatoires".
  • Computer and Industrial engineer, in 5 years after baccalauréat
  • Engineer, Manager, Entrepreneur, in 5 years after baccalauréat, training co-led by the École Centrale de Lille and SKEMA Business School.
Each year , more than 350 graduates are joining the executive staff of many companies. It is also emerging as a key player in the search at national and regional international level . It operates directly as a carrier or partner in six laboratories (including 4 CNRS) and four International Laboratories Shareholders are particularly attached to the School . Thematic coverage of its laboratories is very broad and is consistent with the general character of the training : Industrial Computer , Electronics, Civil Engineering , Nanotechnology / NEMS , Industrial Engineering , Acoustics , Business Modeling , Process Engineering , Fluid Mechanics , Mechanics of Materials , Metallurgy, Electrical Engineering , Information Processing , Automation. Also , the school is empowered by the State to issue own the degree of Master II in 8 specialties and PhD . Each year, it graduates more than thirty doctoral students

Ecole Centrale de Lille in key figures

  • General engineering school, created in 1854, 3 years after preparatory classes on the Central - Supelec competition and possible parallels admissions (ATS and CASTing contest )
  • Member of the Group of Centrale Schools
  • 1500 students including 120 PhD students
  • Internships and placement years in companies in France and abroad
  • 8 months on average spent per student in international
  • 84 foreign university partners : 40% of students are double graduates
  • 20% of foreign students in the School
  • 6 research laboratories including 4 CNRS whose thematic coverage is consistent with the general character of the training : Industrial Computers, Electronics, Civil Engineering , Nanotechnology / NEMS , Industrial Engineering , Acoustics , Business Modeling , Process Engineering , Mechanics fluids, Mechanics of Materials , Metallurgy, Electrical Engineering , Information Processing , Automation
  • 2 engineering degrees in 5 years after baccalauréat ( IG2I and Iteem )
