Impresora tridimensional. Three-dimensional printer
Objeto de la invención. Object of the invention.
La presente invención se refiere a una impresora tridimensional, adecuada para la impresión de piezas o prototipos tridimensionales en resina y que comprende: una bandeja contenedora de una resina fotopolimerizable; una fuente de luz controlada por un sistema de control; una plataforma de modelado adecuada para el soporte del prototipo durante la formación en el mismo de sucesivas capas de resina fotopolimerizable, solidificada mediante la proyección de luz; y un dispositivo de accionamiento adecuado para la separación del fondo de la bandeja de las sucesivas capas de resina solidificadas. The present invention relates to a three-dimensional printer, suitable for printing three-dimensional parts or prototypes in resin and comprising: a tray containing a photopolymerizable resin; a light source controlled by a control system; a modeling platform suitable for prototype support during the formation therein of successive layers of light-curing resin, solidified by light projection; and a drive device suitable for separating the bottom of the tray from the successive layers of solidified resin.
La impresora de la invención presenta unas características orientadas a mejorar la separación de las capas de resina solidificadas del fondo de la bandeja contenedora de la resina fotopolimerizable, y a mejorar el posicionamiento de la plataforma de modelado en un punto determinado previamente a la solidificación de las sucesivas capas de resina en la pieza o modelo tridimensional. The printer of the invention has characteristics oriented to improve the separation of the solidified resin layers from the bottom of the tray containing the light-curing resin, and to improve the positioning of the modeling platform at a certain point prior to the solidification of the successive ones. layers of resin in the part or three-dimensional model.
Esta invención es aplicable en la fabricación de impresoras tridimensionales. This invention is applicable in the manufacture of three-dimensional printers.
Actualmente son conocidas las impresoras tridimensionales, ó 3D, que disponen de una plataforma de moldeo sobre la qué se va formando la pieza o prototipo tridimensional, a partir de la solidificación de sucesivas capas de resina fotopolimerizable. Currently, three-dimensional or 3D printers are known, which have a molding platform on which the three-dimensional part or prototype is formed, from the solidification of successive layers of light-curing resin.
Esta resina se encuentra inicialmente en estado fluido, en el interior de una bandeja contenedora, encontrándose dispuesta por encima o por debajo de la mencionada bandeja una fuente de luz que es controlada de manera conocida por un sistema de control, en el cual el usuario introduce las características de la pieza o prototipo tridimensional a imprimir. This resin is initially in a fluid state, inside a container tray, being arranged above or below said tray a light source that is controlled in a known manner by a control system, into which the user enters the characteristics of the piece or three-dimensional prototype to be printed.
La plataforma de modelado se encuentra asociada a unos medios de desplazamiento vertical que permiten pequeños desplazamientos de la plataforma en sentido ascendente a medida que se van solidificando sobre el extremo inferior de la pieza o prototipo nuevas capas de resina fotopolimerizable por la acción de la fuente de luz. The modeling platform is associated with vertical displacement means that allow small displacements of the platform in an upward direction as new layers of photopolymerizable resin are solidified on the lower end of the piece or prototype by the action of the source of light.
Cada vez que se solidifica una capa de resina se crea un vacío y una adherencia entre dicha capa de resina solidificada y el fondo transparente de la bandeja contenedora, siendo preciso realizar el pelado o separación de dicha capa de resina solidificada del fondo de la bandeja. Each time a resin layer solidifies, a vacuum and adhesion is created between said solidified resin layer and the transparent bottom of the container tray, it being necessary to peel or separate said solidified resin layer from the bottom of the tray.
Para realizar esta operación de separación o pelado se utiliza una técnica conocida que consiste en mover la bandeja contenedora de la resina mientras que la plataforma de modelado y el prototipo o pieza en impresión permanecen estáticos. To perform this separation or peeling operation, a known technique is used that consists in moving the resin tray while the modeling platform and the prototype or piece in print remain static.
Este movimiento de basculación es producido mediante una pieza excéntrica que presiona un lateral de la bandeja hacia la zona inferior, y unos muelles que devuelven la bandeja a su cota cero, o de referencia, en el eje vertical. This tilting movement is produced by an eccentric piece that presses one side of the tray towards the lower area, and springs that return the tray to its zero, or reference, level on the vertical axis.
En estas impresoras 3D, una vez realizado el pelado o separación de la capa de resina solidificada, se desplaza la plataforma de moldeado con un movimiento puramente vertical y de una amplitud adecuada para constituir una nueva capa de resina solidificada sobre el extremo inferior de la pieza o prototipo. In these 3D printers, once the peeling or separation of the solidified resin layer has been carried out, the molding platform is moved with a purely vertical movement and of an adequate amplitude to constitute a new layer of solidified resin on the lower end of the piece or prototype
Esta técnica de pelado o moldeo presenta diversos inconvenientes entre los cuales cabe mencionar: la incorporación en la impresora de dos sistemas de accionamiento diferentes (uno para provocar la basculación de la bandeja y otro para desplazar verticalmente la plataforma de moldeado); posibles errores de reposicionamiento de la bandeja en una cota cero por la acción de los muelles, manteniéndose dicha bandeja en una posición flotante sobre los muelles; y la capacidad de pelar o liberar superficies de impresión de una amplitud reducida al aplicarse la basculación de la bandeja solamente en uno de los laterales de la misma. This peeling or molding technique has several drawbacks, among which are the following: the incorporation into the printer of two different drive systems (one to cause the tilting of the tray and the other to move the molding platform vertically); possible errors of repositioning the tray at a zero level due to the action of the springs, said tray being kept in a floating position on the springs; and the ability to peel or release printing surfaces of a reduced amplitude when the tilting of the tray is applied only on one of the sides thereof.
Por tanto, el problema técnico que se plantea es el desarrollo de una impresora tridimensional que permita resolver la problemática expuesta anteriormente. Therefore, the technical problem that arises is the development of a three-dimensional printer that allows solving the problem described above.
La impresora tridimensional objeto de la invención, comprende una serie de elementos habituales en este tipo de impresoras, tales como: una bandeja contenedora de una resina fotopolimerizable; una fuente de luz controlada por un sistema de control; una plataforma de modelado adecuada para el soporte del prototipo durante la formación en el mismo de sucesivas capas de resina fotopolimerizable solidificada mediante la proyección de luz; y un dispositivo de accionamiento adecuado para la separación o pelado, del fondo de la bandeja, de las sucesivas capas de resina solidificadas en el prototipo. The three-dimensional printer object of the invention comprises a series of elements common in this type of printers, such as: a tray containing a photopolymerizable resin; a light source controlled by a control system; a modeling platform suitable for prototype support during the formation therein of successive layers of solidified photopolymerizable resin by light projection; and a drive device suitable for separating or peeling, from the bottom of the tray, the successive layers of resin solidified in the prototype.
Esta impresora presenta unas particularidades constructivas orientadas a solventar la problemática expuesta anteriormente. Concretamente uno de los objetivos de la invención es utilizar un único dispositivo para desplazar verticalmente la plataforma entre la formación de sucesivas capas de resina solidificada y realizar el pelado o separación de dichas capas respecto al fondo de la bandeja contenedora de la resina, simplificando la fabricación y reduciendo los costes de la impresora tridimensional. This printer has some constructive features aimed at solving the problems described above. Specifically, one of the objectives of the invention is to use a single device to move the platform vertically between the formation of successive layers of solidified resin and to peel or separate said layers from the bottom of the resin container tray, simplifying manufacturing and reducing the costs of the three-dimensional printer.
Otro de los objetivos de la invención es eliminar los errores de reposicionamiento de la bandeja contenedora de la resina en una cota cero, o de referencia, previamente a la solidificación de cada capa de resina. Another object of the invention is to eliminate the repositioning errors of the resin container tray at a zero level, or reference, prior to the solidification of each resin layer.
Otro objetivo de la invención es mejorar el pelado o separación de las sucesivas capas de resina solidificadas del fondo de la bandeja, especialmente en el caso de las superficies de impresión de mayor tamaño. Another object of the invention is to improve the peeling or separation of the successive layers of solidified resin from the bottom of the tray, especially in the case of larger printing surfaces.
Para ello y de acuerdo con invención, en esta impresora tridimensional la bandeja contenedora de la resina fotopolimerizable es fija, es decir, se mantiene estática en la posición correspondiente a la cota cero o de referencia durante el proceso de impresión; mientras que la plataforma de modelado se encuentra montada sobre un dispositivo de accionamiento con posibilidad de desplazamiento vertical y de basculación lateral entre dos posiciones extremas en las qué dicha plataforma forma dos ángulos agudos de sentidos opuestos respecto a la horizontal. For this and according to the invention, in this three-dimensional printer the tray containing the light-curing resin is fixed, that is, it is kept static in the position corresponding to the zero or reference level during the printing process; while the modeling platform is mounted on a drive device with the possibility of vertical displacement and lateral tilting between two extreme positions in which said platform forms two acute angles of opposite directions with respect to the horizontal.
Con estas características se consiguen los objetivos propuestos, ya que al mantenerse la bandeja en una posición fija se eliminan los errores de reposicionamiento de la misma. With these characteristics, the proposed objectives are achieved, since keeping the tray in a fixed position eliminates its repositioning errors.
El montaje de la plataforma de modelado sobre un dispositivo de soporte que permite tanto el desplazamiento vertical de la plataforma para posicionarla a una altura predeterminada previamente a la solidificación de una nueva capa de resina, como la basculación lateral de dicha plataforma para realizar la separación o pelado de las sucesivas capas de resinas solidificada, hace innecesario la utilización de un dispositivo adicional para la basculación de la bandeja, tal como ocurre en las impresoras existentes. The assembly of the modeling platform on a support device that allows both the vertical displacement of the platform to position it at a predetermined height prior to the solidification of a new resin layer, as the lateral tilting of said platform to perform the separation or Peeling the successive layers of solidified resins makes unnecessary the use of an additional device for tilting the tray, as is the case with existing printers.
También cabe mencionar que la posibilidad de basculación lateral de la bandeja, primero hacia un lateral y después hacia el otro respecto a la horizontal, permite realizar un correcto pelado o separación de capas de resina respecto al fondo de la bandeja, incluso en superficies de impresión de gran tamaño. It is also worth mentioning that the possibility of lateral tilting of the tray, first towards one side and then towards the other with respect to the horizontal one, allows a correct peeling or separation of resin layers from the bottom of the tray, even on printing surfaces Large size.
Estas y otras características adicionales de la invención, recogidas en las reivindicaciones, se comprenderán con mayor facilidad a la vista del ejemplo de realización mostrado en las figuras adjuntas. These and other additional features of the invention, set out in the claims, will be more readily understood in view of the exemplary embodiment shown in the attached figures.

Below the tray is a light source (3), connected to a control system (not shown) that is responsible for carrying out the photopolymerization and solidification of successive layers of the resin (2) to form a piece or prototype (4) arranged on a modeling platform (5) located above the tray (1).
La mencionada plataforma (5) se encuentra montada en un dispositivo de accionamiento que comprende, al menos, dos soportes (6) desplazables verticalmente de modo independiente y a los qué se encuentran fijados, con posibilidad de giro respecto a sendos ejes horizontales (7), dos extremos opuestos de un puente (8) portador de la plataforma (5) de modelado, y unos actuadores lineales (11-13) accionables de manera independiente para el desplazamiento vertical de los respectivos soportes (6) desplazables y la basculación de la plataforma (5) en sentidos opuestos respecto a la horizontal. Said platform (5) is mounted on a drive device comprising at least two movable supports (6) that can be moved vertically independently and to which they are fixed, with the possibility of turning with respect to two horizontal axes (7), two opposite ends of a bridge (8) bearing the modeling platform (5), and linear actuators (11-13) independently operable for the vertical displacement of the respective movable supports (6) and the tilting of the platform (5) in opposite directions with respect to the horizontal.
