Unique project of the CATIA DESIGN team: Bleu concept car

    The developers of the CATIA solution at Dassault Systèmes have demonstrated new technologies for modeling cars by example.


    Dassault Systèmes, a leader in 3D design, digital prototyping and product lifecycle management (PLM) solutions, decided to show in its Bleu project how you can implement your own concept car using the latest modeling technologies.

    Design concept car "Bleu":

    The Bleu project team included a designer, two sketch design specialists, two visualization experts, two surface modeling specialists, and one design engineer. The Objet260 Connex 3D printer was purchased, which played an important role in the precise implementation of the project.

    The project “Bleu” was logically divided into five stages.

    At the first stage, the team checked their ideas on reduced samples printed on a 3D printer and not exceeding 5 cm in length. This made it possible to identify in advance potential design flaws.

    At the second stage , 3D samples 10 cm long were prepared for studying and working out the concept car proportions. Designers and designers were convinced that in terms of volume perception and proportions, all elements are perfectly balanced.

    The third stage of the project, without which the automotive industry cannot do without, is the production of a model for testing in a wind tunnel. So far she has no such details as wheels and mirrors; not worked interior.

    After testing in a wind tunnel, the Bleu concept car at the fourth stage was refined and increased in length to 26 centimeters (this is a limitation of the Objet260 Connex printer tray). But she had wheels, mirrors and bumpers.

    Simplified aerodynamic models printed on a 3D printer are ready for aerodynamic testing.

    At the final stageproject "Bleu" was printed fully functional model of the concept car. Engineers made changes to the chassis design so that the wheels could move like a real car. The design of the new chassis was carried out in CATIA Natural Shape; By the beginning of the EuroMold 2013 exhibition, the model was completely ready.

    More about the process of creating a layout:

    To print on a 3D printer, the developers of the Bleu model used several types of PolyJect materials, including black elastic TangoBlackPlus for the manufacture of tires, solid matte white VeroWhitePlus for printing the chassis and transparent VeroClear for the manufacture of windows.

    Although initially Dassault Systèmes wanted only to demonstrate the design and design capabilities of the CATIA solution with the help of the Bleu project, it was subsequently decided to share technical details of the project implementation and publish STL files of the three-dimensional model to familiarize the wide audience.

    Let us tell you a little more directly about the process of preparing a three-dimensional model for 3D printing .

    The process of preparing a three-dimensional model for 3D printing covers work in various applications that help prepare three-dimensional geometry depending on printing conditions. First, the model should be team / non-demountable. Secondly - the possibility of printing from different materials should be provided.

    Dassault Systèmes solutions portfolio also covers the process of additive manufacturing. This process includes the development and design of three-dimensional geometry, as well as generating design technology. Moreover, it provides tools for calculating and analyzing the model itself at operational loads, as well as calculating the printing process on the machine. There are all the necessary tools for the layout of the tray, the construction of the reference geometry for printing and the creation of control print programs.

    Step-by-step process for preparing for 3D printing in CATIA 3DEXPERIENCE is shown on the slide:
