- additive manufacturing process is understood to mean a manufacturing process by adding material, generally aided by computer. Such a manufacturing process is also called three-dimensional printing or even 3D printing.
- the use of three-dimensional printing can make it possible to produce in a single step an applicator 1 comprising a core 2 having protuberances 9.1, 9.2 and at least one cavity 5 and at least one moving part 7 included in one of the cavities 5.
- an applicator 1 comprising a core 2 having protuberances 9.1, 9.2 and at least one cavity 5 and at least one moving part 7 included in one of the cavities 5.
- the three-dimensional printing is used to form the core 2 with the sleeve 4 and / or the rod 3.
- EBM Electron Beam Melting in English
- SLA Stereolithography Apparatus in English
- these are sintering and / or stereolithography technologies.
- the invention also relates to a method of manufacturing an applicator 1 as described above.
- the process includes:
- the digital model is a computer file which corresponds to a virtual model of the applicator 1.
- the applicator 1 is first of all modeled so as to obtain a CAD model which is then converted into an appropriate format such as than a “.STL” file.
- the file is then used on an additive manufacturing machine.
- the digital model is cut into a number of layers depending on the desired precision.
- the layers correspond to a cross section of the applicator 1, that is to say a section of the applicator 1 taken in a plane perpendicular to the longitudinal main direction X.
- Suitable materials for making the applicator 1 by three-dimensional printing are polyamides, photosensitive resins, polylactic acid (PLA), acrylonitrile butadiene styrene (ABS).
- the invention also relates to an applicator assembly 35 for a cosmetic product, comprising the container 37 comprising a body 39 forming a reservoir intended to contain the cosmetic product (not shown), and an applicator 1, as described above, adapted to be attached to the cosmetic product. the container 37, so that the applicator 1 is housed inside the reservoir.
- the applicator 1 is fixed, for example, to a proximal end of the rod 3, itself fixed to a stopper 41 advantageously screwed to the container 37.
- the applicator assembly 35 can be obtained in whole or in part by three-dimensional printing.
