SECTOR DE LA TÉCNICA TECHNIQUE SECTOR
La presente solicitud se refiere a un bolígrafo para impresión 3D que resulta en una mejora sobre el estado de la técnica en cuanto a la fiabilidad, así como la versatilidad en el uso.. The present application refers to a pen for 3D printing that results in an improvement over the state of the art in terms of reliability, as well as versatility in use.
ESTADO DE LA TÉCNICA STATE OF THE TECHNIQUE
En el merado existen diferentes modelos de bolígrafos de impresión 3D, sin embargo para su funcionamiento estos bolígrafos disponen de una pluralidad de engranajes que hacen que su fabricación y su montaje sea más costoso. There are different models of 3D printing pens on the market, however for their operation these pens have a plurality of gears that make their manufacturing and assembly more expensive.
Además de que el hecho de tener un mayor número de piezas y mecanismos para su funcionamiento hace que tengan lugar más averías en el producto, ofreciendo una peor calidad al cliente. In addition, the fact of having a greater number of parts and mechanisms for its operation causes more breakdowns to occur in the product, offering poorer quality to the customer.
El solicitante no conoce ninguna solución a estos problemas similar a la invención. The applicant is not aware of any solution to these problems similar to the invention.
BREVE EXPLICACIÓN DE LA INVENCIÓN BRIEF EXPLANATION OF THE INVENTION
La invención se refiere a un bolígrafo de impresión 3D según las reivindicaciones, cuyas realizaciones mejoran y resuelven los problemas de la técnica. The invention relates to a 3D printing pen according to the claims, whose embodiments improve and solve the problems of the technique.
El bolígrafo para impresión 3D comprende una carcasa hueca, que dispone en su extremo superior de una boca de entrada de material. Por esta boca de entrada el usuario introducirá el filamento del material que se va a fundir posteriormente. The 3D printing pen comprises a hollow casing, which has a material inlet at its upper end. Through this inlet the user will introduce the filament of the material that is going to be melted later.
Por otra parte el extremo inferior de la carcasa está unido con un cabezal que dispone de un orificio por donde sale el material fundido, estando el orificio unido con un conducto que recorre longitudinalmente el interior de la carcasa. On the other hand, the lower end of the casing is connected to a head that has a hole through which the molten material comes out, the hole being connected to a duct that runs longitudinally through the interior of the casing.
Así conseguimos conducir el filamento desde la boca de entrada hasta el orificio por donde saldrá al exterior fundido. In this way we manage to guide the filament from the inlet mouth to the hole through which It will come out molten.
Para fundir el material se dispone, envolviendo el orificio, un elemento calefactor alimentado por una fuente de alimentación eléctrica y comandando por un panel de control. To melt the material, a heating element fed by an electrical power source and controlled by a control panel is arranged, surrounding the hole.

MODOS DE REALIZACIÓN DE LA INVENCIÓN MODES OF EMBODIMENT OF THE INVENTION
A continuación, se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta. Next, a way of carrying out the invention is briefly described, as an illustrative and non-limiting example of it.
El bolígrafo para impresión 3D comprende una carcasa (1 ) hueca, que dispone en su extremo superior de una boca de entrada (6) de material, y estando unido el extremo inferior de la carcasa (1 ) con un cabezal (2) que dispone de un orificio (3) por donde sale el material fundido, estando conectado el orificio (3) con un conducto (4) que recorre longitudinalmente el interior de la carcasa (1 ) , de tal manera que envolviendo el orificio hay dispuesto un elemento calefactor alimentado por una fuente de alimentación eléctrica y comandando por un panel de control. The 3D printing pen comprises a hollow casing (1), which has at its upper end an inlet mouth (6) of material, and the lower end of the casing (1) being joined with a head (2) that has of a hole (3) through which the molten material comes out, the hole (3) being connected to a duct (4) that runs longitudinally inside the casing (1), in such a way that a heating element is arranged surrounding the hole. powered by an electrical power source and commanded by a control panel.
En un modo de realización preferente el elemento calefactor es una resistencia eléctrica, de tal manera que la resistencia eléctrica, que está dispuesta alrededor del orificio (3) calienta el material consiguiendo fundirlo de tal manera que cuando el material sale al exterior del bolígrafo sale fundido, permitiendo que el usuario pueda crear figuras en tres dimensiones. In a preferred embodiment, the heating element is an electrical resistance, in such a way that the electrical resistance, which is arranged around the hole (3), heats the material, melting it in such a way that when the material comes out of the pen, it comes out molten. , allowing the user to create three-dimensional figures.
Generalmente el panel de control estará conectado con un conjunto de botones (5) dispuestos en el exterior de la carcasa (1 ) . Estos botones (5) serán por lo tanto accesibles por el usuario, el cual podrá modificar ciertos parámetros como la velocidad de salida del filamento de material a fundir, la temperatura a la que se calienta la resistencia eléctrica, ... Preferentemente, la fuente de alimentación eléctrica es una batería recargable. De esta manera el usuario podrá utilizar el bolígrafo de manera inalámbrica, permitiendo una mayor libertad de movimientos. También podrá utilizarlo con la conexión del cable de red. Generally the control panel will be connected to a set of buttons (5) arranged on the outside of the casing (1). These buttons (5) will therefore be accessible by the user, who will be able to modify certain parameters such as the output speed of the filament of material to be melted, the temperature at which the electrical resistance is heated,... Preferably, the electrical power source is a rechargeable battery. In this way the user will be able to use the pen wirelessly, allowing greater freedom of movement. You can also use it with the network cable connection.
La carcasa (1 ) podrá disponer de una pantalla de visualización (7) donde el usuario podrá visualizar diferentes parámetros como el estado de carga de la batería, la velocidad de avance del filamento de material, la temperatura de la resistencia eléctrica, ... La parte inferior de la carcasa (1 ) dispondrá de una serie de orificios de ventilación (8) con el objetivo de disipar el exceso de calor generado. The housing (1) may have a display screen (7) where the user can view different parameters such as the state of charge of the battery, the speed of advance of the material filament, the temperature of the electrical resistance,... The lower part of the casing (1) will have a series of ventilation holes (8) in order to dissipate the excess heat generated.
