 Method for producing a three-dimensional object

description

The invention relates to a method for producing an object for the memory of an event, during which at least one trajectory of at least one object is recorded during the event and such an object.

For any event, especially sports events, it may be helpful to capture trajectories of objects. For example, in football matches, the trajectories of the football players are recorded to determine their mileage and to record other statistical values of their performance during the game. Further, in football games, the trajectory of the ball can be recorded. For example, GoalControl GmbH offers a system that records the trajectory of a ball with several high-speed cameras to determine if the ball is behind the goal line.

In other games such as tennis, ice hockey games trajectories of the players and / or the game equipment can be detected.

The object of the present invention is the production of an object for the memory of such an event as a sports event with a striking characteristic of the event design and the memory object itself.

With regard to the method, the object is achieved by using a three-dimensional reproduction method as a component of the opposite a three-dimensional reproduction of the recorded trajectory is generated.

The three-dimensional reproduction of the trajectory should be arranged on or in the object in a manner visible to a viewer of the object. The recorded trajectory can be reproduced three-dimensionally in real time during the recording. Alternatively, the recorded trajectory can be stored in a file and the stored motion data can be reproduced.

The period of time over which the trajectory to be reproduced is detected can be varied as desired. For football games it may be useful to record only the time periods (eg 20 seconds). Even with tennis, it can be decided that only the trajectory of the ball is recorded and reproduced in the last set or last game. However, it is also possible to select longer time periods or the entire playing time and to choose the trajectories of several objects, in particular ball and player. In this case, a very closely structured reproduction arises.

The reproduction of the trajectory can be done with 3D printers (three-dimensional printers). Such printers belong to the three-dimensional manufacturers and make it possible to generate arbitrary three-dimensional forms digitally controlled by additive material application. By selective laser melting or electron beam melting, for example, structures made of metal can be produced in 3D printing processes. Selective laser sintering is also suitable for polymers, ceramic materials and metals. Stereolithography and digital light processing are suitable for processing liquid synthetic resins. Plastic molds can be produced by polyjet modeling and fused deposition modeling. The resolution eg of synthetic resin printers can be far below 0, 1 mm. In the context of the present method, the digital data of the movement path can be supplied to the 3D printer, so that it creates a three-dimensional structure from this data.

However, other methods for generating three-dimensional images are known. By means of lasers, visible structures can be produced in transparent bodies, especially in the interior of glass plates or glass blocks. In laser engraving, by focusing a spot of light in the interior of a glass, the glass structure is changed in such a way that a point-like, visible from the outside devitrification emerges. A plurality of these points can produce any three-dimensional images inside a glass body.

By selective laser etching, in transparent materials, especially glass, a fine array of channels can be created, representing any three-dimensional structures. This manufacturing process for processing transparent materials such as glass and sapphire was developed by the Fraunhofer Institute for Laser Technology I LT in Aachen and is referred to as selective laser etching (in-volume selective laser etching ISLE). In this method, ultrashort pulsed laser radiation is focused within a transparent workpiece similar to the laser engraving and absorbed only in the focus volume. In this focus volume, the transparent material is changed without cracks in its optical and chemical properties such that it becomes selectively chemically etchable. By moving the focus with the aid of a micro-scanner, those areas are exposed which are subsequently to be removed by wet-chemical etching. Thus, for example, microchannels and mold holes can be made in glass. Further information on the selective laser etching can be found in the publication in the journal Mikroproduktion 06/201 0 of Carl Hanser Verlag, Munich, page 1 0-1 3, ISSN 1 61 4-4538. Reproductions of trajectories made with such laser replication methods in a crystal glass block or crystal plate have an extremely high-quality appearance and are eminently suitable for forming a valuable memento of a particular event represented by the illustrated trajectories.

In the same laser-assisted reproduction method, further representations may be reproduced on the item, such as the name of the sporting event, the date of the event, the score of the final match, the opposing athletes or teams, the location of the event, etc.

Further, the trajectory may be mechanically formed from an elongate member such as a wire or a flexible tube, which is then fixed in the generated shape of the trajectory. The fixing can be carried out by means of adhesive or by melting and by welding the material of the elongate element. If additional representations are to be applied to the object during this reproduction of the trajectory, writing tablets, impressions and impressions and other conventional representation methods are suitable.

As a rule, the trajectory is applied to the object reduced in scale. But it is quite possible to produce a large representation on a scale of 1: 1, or even a magnification ßerte representation of the trajectory. This landscape objects of several meters, z. B. 1 00 m, length and similar width arise.

If the article produced has a different form from the most flat surface of the playing field, for example, if the object is a cup with cylindrical or other rotationally symmetric surface, the base surface of the reproduction of the trajectory can be adapted to the curved surface of the object. In a field game, the base is usually even. It can be terprogramme be wrapped in the form of a cylinder or other rotationally symmetrical body to form a cup. Further 3-dimensional distortions are possible.

The invention also relates to the article produced according to the method described above with a visible three-dimensional reproduction of the at least one movement path of an object.

The event for which the item is made can be anything. Any field games (soccer, handball, basketball, tennis, ice hockey etc.) have already been mentioned. A Formula 1 race is also suitable, whereby the trajectory of the race car, recorded at least over several laps, reflects the typical route of the race track. In addition, z. B. in the laser engraving or laser etching the contour of the winning car and the face of the winner are displayed. However, this type of presentation can be applied to any other events such as billiards, ballet, dance, bowling, etc.

During the competition, the data are stored, immediately thereafter the outer shape of the object, e.g. As a cup, generated, possibly including the appropriate label and badge.

Immediately starts the 3D printing process in metal pigment, sintered or epoxy-based, or even the system for the production of laser engraving. Cups, medals, etc. are available shortly after the game ends. The players hold their own performance in their hands - as a permanent work.

Embodiments of the invention will be described below with reference to the accompanying drawings.

FIG. 3 shows a side view of the article from FIG. 1. FIG.

Fig. 4 shows an alternative embodiment of an article in memory of a soccer ball game in three-dimensional plan view.

Fig. 5 shows the article of Fig. 4 in a different perspective.

Fig. 6 shows a three-dimensional distortion of the trajectory for placement on a cylindrical object.

The object shown in Figs. 1 to 3 in memory of a football game consists of a base plate 1, on which the trajectory of Fu ßballs is shown by elongated, curved wire-like elements 2. The trajectory of Fu ßballs was previously played during the football match z. B. recorded by multiple cameras. The elongated, wire-like elements 2 can be applied to the base plate 1 in various ways. They may be formed from metal wire and bent and soldered to the base plate 1, be welded or glued. The wire can be tapped from a roll and applied to the base plate 1 by a numerically-controlled dispensing head of a machine corresponding to the previously recorded trajectory of the foot.

The wire-like elements 2 may alternatively be made of plastic or other fusible material. For example, a 3D printer can apply plastic material in the form of the previously recorded trajectory of the football. 3D printers can also wire-like elements 2 made of other materials, eg. As ceramic or metal produce. The edges of the base plate 1 may be labeled to identify the event in which the trajectory was recorded. For example, the label can be milled. If the trajectory of the football is recorded, this can be done, for example, with a plurality of high-speed cameras, as known from the goal-line monitoring system marketed by GoalControl.

With multiple cameras, but also the trajectory of football players, referees, etc. can be recorded, which can be optionally mounted on the memory item. The trajectory, can also be used in any other sporting events, eg. As a tennis game, a vehicle race, etc. recorded.

The object of remembrance has a very abstract appearance, but reproduces to the highest degree realistic the event he remembers.

Figs. 4 and 5 show another embodiment of the subject of the invention. Here, the memorial article consists of a transparent block of material 3. The transparent block of material 3 may, for example, have a surface with the dimensions of a DI N A4 sheet and a thickness of, for example, 5 cm. On a reduced scale, the movement path 4 is introduced into this material block 3. According to a first manufacturing method, the movement path 4 can be introduced by a so-called laser internal engraving. Here, the light spot of the laser focuses inside a glass block and visibly changes the glass structure in the focal point, so that a point-like, visible from the outside devitrification emerges. A plurality of these points can reproduce the trajectory 4. Furthermore, inscription or any desired images can be introduced by laser engraving in the volume of the transparent material block 3. The movement path 4 can also be introduced by laser etching in the material block 3 in accordance with a second production method. Similar to the laser engraving, the glass along the trajectory 4 is changed in its structure by a focused laser beam. Subsequently, the glass material is etched out by an acid. This creates hollow channels within the glass block, which reflect the trajectory.

FIG. 6 shows a further embodiment of a movement path 5, which was initially recorded above its ground plane, as a rule the surface of a playing field, was subsequently reduced to scale and was imaged onto a curved base. The curved base is cylindrical. The trajectory 5 is thus within a cylindrical shell with an annular cross-section. Such a movement path 5 can be introduced either in a cylinder-jacket-shaped transparent material body via the laser internal engraving or selective laser etching. It can alternatively be applied to a body with a cylindrical outer surface by means of a 3D printer or another imaging method. In this way, memorabilia according to the invention are created in the form of cups. The ground plane can also be imaged onto a rotationally symmetrical surface deviating from a cylindrical surface.

The features of the invention disclosed in the present description, in the drawings and in the claims may be essential both individually and in any desired combinations for the realization of the invention in its various embodiments. LIST OF REFERENCE NUMBERS
