Description
Domaine technique de l'inventionTechnical field of the invention
La présente invention est relative à l’étanchéité de pièces en polymères notamment celles produites en fabrication additive par un traitement thermique.The present invention relates to the sealing of polymer parts, in particular those produced by additive manufacturing by heat treatment.
Arrière-plan techniqueTechnical background
La fabrication additive, dont le « dépôt de filament fondu » (procédé FDM ou FFF pour Fused Filament Fabrication en anglais), est un procédé de création d’objets tridimensionnels à partir d’un fichier numérique. Elle permet de créer un objet couche par couche, par ajout/dépôt de matière jusqu’à obtenir la pièce finale. C’est un procédé novateur qui, a contrario des procédés conventionnels, dépose de la matière uniquement où cela est nécessaire afin de réaliser la pièce. Ce procédé permet de produire des géométries complexes mais présente l’inconvénient de générer des porosités qui peuvent être importantes, altérant ainsi l’étanchéité des pièces produites.Additive manufacturing, including “fused filament deposition” (FDM or FFF process for Fused Filament Fabrication in English), is a process for creating three-dimensional objects from a digital file. It allows you to create an object layer by layer, by adding/depositing material until you get the final part. It is an innovative process which, unlike conventional processes, deposits material only where it is necessary in order to produce the part. This process makes it possible to produce complex geometries but has the disadvantage of generating porosities which can be significant, thus altering the tightness of the parts produced.
Un traitement post fabrication additive s’avère donc nécessaire pour rendre les pièces ainsi produites étanches.A post additive manufacturing treatment is therefore necessary to make the parts thus produced watertight.
Il existe sur le marché différent sous-traitants offrant, de par leur savoir-faire technique (chimique ou mécanique), des solutions afin d’améliorer l’étanchéité des pièces. Ces techniques possèdent des avantages mais aussi des inconvénients. En effet, les traitements de surface mécaniques sont relativement simples à mettre en œuvre mais le processus est long et demande de la main d’œuvre, ils offrent des résultats variables, présentent un risque d’incrustation et ne peuvent pas être utilisés à l’intérieur de cavités. Les traitements de surface chimiques peuvent nécessiter la présence de solvants toxiques et ne respectent pas forcement les normes FST.There are various subcontractors on the market offering, through their technical know-how (chemical or mechanical), solutions to improve the tightness of parts. These techniques have advantages as well as disadvantages. Indeed, mechanical surface treatments are relatively simple to implement but the process is long and requires labor, they offer variable results, present a risk of incrustation and cannot be used at the same time. interior of cavities. Chemical surface treatments may require the presence of toxic solvents and do not necessarily comply with FST standards.
Les solutions de traitement de surface actuellement sur la marché sont soit soustractives (par exemple le sablage, la tribofinition, etc.), soit additives (par exemple spray, film, etc.). Les dimensions géométriques des pièces traitées par ces procédés sont donc impactées : soit des surépaisseurs sont ajoutées sur la surface des pièces traitées, soit la pièce traitée a des dimensions localement inférieures. FR3 082 774 décrit le traitement thermique d’une pièce en matériau plastique chargé obtenue par fabrication additive. Le traitement thermique a pour effet d’une part de réduire significativement le niveau de porosité, et d’autre part d’augmenter significativement les performances mécaniques de la pièce, en particulier son allongement et sa contrainte à la rupture. Toutefois, ce document ne fait aucune référence à l’étanchéité des pièces traitées. En fait, les conditions opératoires décrites dans ce document, ne permettent pas de rendre la pièce en polymère étanche au sens de l’invention. Par ailleurs, les pièces fabriquées sont en matériau plastique chargé et la température du traitement thermique est inférieure ou égale à 200°C.The surface treatment solutions currently on the market are either subtractive (eg sandblasting, tribofinishing, etc.) or additive (eg spray, film, etc.). The geometric dimensions of the parts treated by these processes are therefore impacted: either extra thicknesses are added to the surface of the treated parts, or the treated part has locally smaller dimensions. FR3 082 774 describes the heat treatment of a part in filled plastic material obtained by additive manufacturing. The heat treatment has the effect on the one hand of significantly reducing the level of porosity, and on the other hand of significantly increasing the mechanical performance of the part, in particular its elongation and its stress at break. However, this document makes no reference to the tightness of the treated parts. In fact, the operating conditions described in this document do not make it possible to seal the polymer part within the meaning of the invention. Furthermore, the manufactured parts are made of filled plastic material and the heat treatment temperature is less than or equal to 200°C.
A ce jour, aucun traitement thermique visant à rendre étanche les pièces obtenues notamment par fabrication additive, n’est décrit.To date, no heat treatment aimed at sealing the parts obtained in particular by additive manufacturing, is described.
Il existe donc un réel besoin de rechercher une solution rapide, efficace et à moindre frais afin de palier à l’inconvénient lié au problème d’étanchéité des pièces post fabrication additive.There is therefore a real need to seek a quick, efficient and inexpensive solution to overcome the inconvenience related to the problem of sealing of post additive manufacturing parts.
En particulier, il existe un réel besoin d’un procédé pour rendre étanche une pièce en polymère produite par fabrication additive, sans modifier la géométrie desdites pièces.In particular, there is a real need for a process for sealing a polymer part produced by additive manufacturing, without modifying the geometry of said parts.
La présente invention a précisément pour but de répondre à ce besoin en proposant un procédé visant à rendre étanche des pièces en polymère, notamment celles obtenue par fabrication additive.The purpose of the present invention is precisely to meet this need by proposing a method aimed at sealing polymer parts, in particular those obtained by additive manufacturing.
L’invention a donc pour objet un procédé pour rendre étanche une pièce en polymère obtenue par fabrication additive, caractérisé en ce que la pièce en polymère obtenue par fabrication additive est soumise à un traitement thermique à une température supérieure à 200°C pendant une durée d’au moins 1 heure.The subject of the invention is therefore a method for sealing a polymer part obtained by additive manufacturing, characterized in that the polymer part obtained by additive manufacturing is subjected to a heat treatment at a temperature above 200° C. for a period at least 1 hour.
Dans le cadre de l’invention la pièce en polymère peut être fabriquée par tout procédé de fabrication additive connue, comme par exemple celle décrite dans FR3 082 774, https://www.3dhubs.com/fr/bases-de-connaissances/technologies-fabrication-additives-apercu/, https://www.a3dm-magazine.fr/news/fabrication-additive-polymeres/procede-dimpression-3d-fdm-fff.In the context of the invention, the polymer part can be manufactured by any known additive manufacturing process, such as that described in FR3 082 774, https://www.3dhubs.com/fr/bases-de-connaissances/ technologies-fabrication-additives-apercu/, https://www.a3dm-magazine.fr/news/fabrication-additive-polymeres/procede-dimpression-3d-fdm-fff.
Le traitement thermique post fabrication additive dans les conditions de l’invention présente l’avantage de rendre les pièces étanches sans modifier leur géométrie, contrairement aux traitements de surface actuellement sur le marché et décrits plus haut, qui impactent les dimensions géométriques des pièces traitées (ajout de surépaisseurs ou production de la pièce avec des dimensions localement inférieures).Post-additive manufacturing heat treatment under the conditions of the invention has the advantage of making the parts airtight without modifying their geometry, unlike the surface treatments currently on the market and described above, which impact the geometric dimensions of the treated parts ( addition of extra thicknesses or production of the part with locally smaller dimensions).
L’utilisation d’un traitement thermique est couramment utilisée pour les pièces métalliques issues de fabrication additive afin d’améliorer la cohésion du matériau et d’éliminer les contraintes résiduelles. Elle n’a, cependant, jamais été décrite comme moyen pour rendre un matériau étanche.The use of heat treatment is commonly used for metal parts resulting from additive manufacturing in order to improve the cohesion of the material and to eliminate residual stresses. It has, however, never been described as a means of sealing a material.
Une pièce en polymère produite par fabrication additive et rendue étanche par le procédé de l’invention aura donc étanche sans modification de sa géométrie.A polymer part produced by additive manufacturing and made watertight by the process of the invention will therefore be watertight without modifying its geometry.
