Stars in metamaterials

Mediathena - 22/07/2019

3D printing allows scientists to create metamaterials, i.e. materials whose properties can be configured and graded within the same part. When it comes to using these materials in an industrial context, the possibilities are endless. A collaborative project led by Jonàs Martínez, researcher within the MFX team, a joint undertaking involving Nancy-Grand Est and Loria, resulted in the development of an algorithm capable of generating materials with elastic properties that can be adjusted to suit requirements. The work, which was based around the repetition of patterns defined from star shaped distances, the parameters of which determine the final properties of the material, will be unveiled at the international conference SIGGRAPH 2019.

An algorithm for creating high-contrast irregular patterns

Mediathena - 22/07/2019

How can we digitally recreate the unevenness of tree bark, sand or roughcasting in such a way that they appear natural? The answer comes from the MFX (Inria Nancy-Grand Est and Loria) and Maverick (Inria Grenoble) project teams, who worked together to develop an innovative algorithm capable of generating such patterns on surfaces. An upgrade on the previous standard in the field (Gabor Noise), Procedural Phasor Noise is set to be unveiled at the international conference SIGGRAPH 2019, and will enable users to generate complex patterns with previously unachievable levels of control. Designed for 3D printing, it will also make it easier to manufacture composite materials whose physical properties may vary depending on the direction.

Smoother 3D prints

Mediathena - 23/07/2019

Two project teams, MFX (Matter from Graphics) and Pixel, joint undertakings involving Inria and Loria based in Nancy, have developed an innovative software for the 3D printing of curved surfaces. In order to avoid “the staircase effect”, the new algorithm CurviSlicer divides the shape of the part to be printed into curved slices in such a way that the deposition follows the surfaces naturally. This makes it possible to perform deposition along smooth curved surfaces using a conventional fused filament 3D printer. Their work will be unveiled at the international conference SIGGRAPH on 31st July 2019.
