Abstract

The model (7) has a hollow head element, leg elements and a base element (6), where the head and leg elements are filled with resin (3). The head element and the leg elements are joined by a screw (12), where the ends of the screw are dipped into the resin, and an empty space (13) is created among the head and the leg elements. The leg elements are glued to the base element at glue points (8), where the elements are assembled after three-dimensional (3D) printing.

Description

Nous emploierons dans ce document l'abréviation « 3D » pour les termes « tridimensionnel » ou « trois dimensions ». Nous admettrons, par ailleurs, qu'une figurine est une statuette de petite taille (ou une représentation à l'échelle) d'un être humain (ou d'un personnage de fiction). Enfin « consommable » et « matière première » auront ici la même signification. La présente invention concerne les figurines fabriquées par le procédé d'impression 3D. La fabrication de ces figurines nécessite dans un premier temps, la modélisation 3D des figurines, puis dans un second temps, l'impression 3D des modèles 3D. Traditionnellement, les figurines fabriquées par impression 3D sont fabriquées en une seule fois et sont pleines. Le temps de fabrication de ces figurines est généralement long - plusieurs heures pour une figurine de 17cm - et la consommation de matières premières est celle qui a été prévue par le constructeur de la machine, également fournisseur de matières premières. Pour optimiser un cycle d'impression 3D, en temps et matières premières, il est recommandé de faire en sorte que l'axe le plus long des figurines à fabriquer soit parallèle au fond du bac de fabrication de l'imprimante 3D. Si cette technique permet de réduire considérablement le temps de fabrication et la quantité de matières premières consommée, des optimisations sont encore possibles en agissant au niveau de la conception des figurines. Les figurines selon l'invention sont fabriquées plus rapidement et avec moins de consommables que ce qui est prévu normalement, lorsque les figurines sont pleines et fabriquées en seule fois. L'invention est une figurine creuse fabriquée en plusieurs 30 éléments à assembler. Selon cette invention la figurine est fabriquée en plusieurs éléments. A titre d'exemple non limitatif, une figurine d'être humain peut être segmentée en trois éléments distincts. L'élément « tête et tronc », l'élément « jambes », l'élément 35 « socle ». La segmentation de la figurine à produire permet de mieux contrôler l'agencement de la pièce à fabriquer dans le bac de fabrication de l'imprimante 3D. Ainsi, la disposition des éléments à produire selon leur plus grand axe et selon leur plus petite hauteur permet de réduire considérablement le temps de fabrication. A titre d'exemple non limitatif, une figurine d'être humain de 17 cm avec un socle rond de 8cm est fabriquée en 270 minutes lorsqu'elle est disposée selon son plus grand axe et selon sa plus petite hauteur dans le bac de fabrication de l'imprimante 3D. La segmentation de la même pièce peut ramener son temps de fabrication à 120 minutes. Les différents éléments de la figurine peuvent être creux. A titre d'exemple non limitatif, une figurine de 17cm d'être humain composée de trois éléments distincts, peut avoir le tronc creux, les jambes creuses et le socle plein. Le creusement de la pièce au niveau du tronc et des jambes peut réduire le temps de fabrication de 15% et la quantité de matières premières de 14,5%. L'assemblage des éléments de la figurine s'effectue après l'étape d'impression 3D. A titre d'exemple non limitatif, une résine de remplissage - beaucoup moins cher et tout aussi efficace que le consommable de l'imprimante 3D utilisé à cet effet - peut être utilisée pour combler le vide des éléments creusés. Les éléments à assembler, comme le tronc et les jambes d'une figurine d'être humain, peuvent être assemblés avec une vis dont les extrémités seront plongées et fixées par la résine de remplissage. Ainsi, la résine remplira la fonction de remplissage et la fonction d'aide à l'assemblage. Les jambes et le socle peuvent être collés avec de la glue. Selon les modes particuliers de réalisation : - les figurines comportent plus ou moins d'éléments à assembler espaces creux sont plus ou moins volumineux - le remplissage est facultatif - le remplissage est s'effectue un matériel quelconque - l'assemblage s'effectuer avec des liants ou avec des tiges ou autres matériaux en métal ou plastique. We will use in this document the abbreviation "3D" for the terms "three-dimensional" or "three-dimensional". We will admit, moreover, that a figurine is a small statuette (or a scale representation) of a human being (or a fictional character). Finally "consumable" and "raw material" will have the same meaning here. The present invention relates to figurines manufactured by the 3D printing process. The manufacture of these figurines requires, initially, the 3D modeling of the figurines, then in a second time, the 3D printing of the 3D models. Traditionally, figurines manufactured by 3D printing are manufactured in one go and are full. The production time of these figurines is usually long - several hours for a 17cm model - and the consumption of raw materials is that which was planned by the manufacturer of the machine, also supplier of raw materials. To optimize a 3D printing cycle, in terms of time and raw materials, it is recommended to make sure that the longest axis of the figurines to be manufactured is parallel to the bottom of the manufacturing tray of the 3D printer. If this technique can significantly reduce the time of manufacture and the amount of raw materials consumed, optimizations are still possible by acting on the design of the figures. The figures of the invention are manufactured faster and with less consumables than is normally expected, when the figures are full and manufactured only once. The invention is a hollow figurine manufactured in several elements to assemble. According to this invention the figurine is made of several elements. As a non-limiting example, a human figure can be segmented into three distinct elements. The element "head and trunk", the element "legs", the element 35 "base". The segmentation of the figurine to be produced allows for better control over the layout of the part to be manufactured in the manufacturing tray of the 3D printer. Thus, the arrangement of the elements to be produced according to their largest axis and according to their smaller height makes it possible to considerably reduce the manufacturing time. By way of non-limiting example, a 17 cm human figure with a round base of 8 cm is manufactured in 270 minutes when it is arranged along its longest axis and at its smallest height in the production tray. the 3D printer. Segmentation of the same part can reduce its manufacturing time to 120 minutes. The different elements of the figurine can be hollow. As a non-limitative example, a human figure of 17cm composed of three distinct elements, may have the hollow trunk, the hollow legs and the solid base. Digging the trunk and leg room can reduce the manufacturing time by 15% and the amount of raw materials by 14.5%. Assembly of the figurine elements is done after the 3D printing step. By way of non-limiting example, a filler resin - much cheaper and just as effective as the consumable of the 3D printer used for this purpose - can be used to fill the void of the excavated elements. The elements to be assembled, such as the trunk and the legs of a human figurine, can be assembled with a screw whose ends will be immersed and fixed by the filling resin. Thus, the resin will fulfill the filling function and the assembly assist function. The legs and the base can be glued with glue. According to the particular modes of realization: - the figurines comprise more or less elements to assemble hollow spaces are more or less voluminous - the filling is optional - the filling is carried out any material - the assembly to be carried out with binders or with rods or other materials of metal or plastic.
