Definitions
- the invention relates to a method and an apparatus for producing three-dimensional models by means of layer construction technology.
- the European patent EP 0 431 924 B1 describes a method for producing three-dimensional objects from computer data.
- a thin layer of a particulate material is applied to a platform and this is selectively printed with a binder material using a print head.
- the particle area printed with the binder adheres and solidifies under the influence of the binder and, if necessary, an additional hardener.
- the platform is then lowered into a construction cylinder by a layer thickness and provided with a new layer of particle material which is also printed, as described above. These steps are repeated until a certain desired height of the object is reached.
- a three-dimensional object is created from the printed and solidified areas.
- This object which is made of solidified particle material, is embedded in loose particle material after its completion and is then freed from it. This is done, for example, by means of a sucker. All that remains are the desired objects, which are then removed from the residual powder e.g. can be freed by brushing.
- coaters can, for example, have an adjustable opening, often in the form of a gap. This gap can, for example, extend over a large part of the width of the coater.
- a problem with known coaters using an adjustable slot or opening is that the gap size or the gap opening has to be enlarged in order to be able to dispense a larger quantity of particulate material. This may influence the controllability of the particle exit, because it can happen that the gap or slit can no longer be controlled, since particle material emerges even at a standstill.
- the coater blade In order to be able to form a pouring cone for closing in a large opening of the coater, the coater blade would have to be designed in dimensions that would be structurally problematic, since the usable coater dimensions would then make the construction site size uneconomical. In particular, a very long coater blade would have to be used in order to be able to build up a pouring cone which can cause the gap to close. However, a large-sized coater blade would reduce the buildable space and thus reduce economy. Another problem is the start-up speed or the delay in the gap opening of oscillating blade coater openings closed by pouring cone due to vibration and the associated quality problems due to insufficient
- the problem here is that the coater is moved or started at a certain speed.
- the coater travels a certain distance above the construction site, while the vibration in the vibrating blade coater causes the cone closure to collapse and particle material to flow out.
- the particulate matter begins to flow out too late and that insufficient particulate matter is applied to a certain part of the construction site.
- it can result in either too little volume of particle material or no particle material being applied in certain areas of the construction field in this time window.
- Another object of the present invention was to modify a coater in such a way that a large amount of particulate material can be applied from a coater to the construction platform and at the same time the gap opening of the coater can be completely closed and the coater can still be moved at high speed can, in order to achieve advantageous and / or shortened manufacturing times.
- a further object of the present invention was therefore to provide a method, a material system and / or a device which helps to reduce the disadvantages of the prior art or avoids or prevents them entirely.
- the invention relates to a closure device suitable for a 3D printing device and / or coating device, comprising a controllable closure means.
- the invention relates to a 3D printing device which comprises a controllable closure means.
- the invention relates to a method for producing 3D shaped parts, wherein particulate building material is applied in a defined layer by means of a coater to a construction field, is selectively solidified in order to obtain a 3D shaped part, the coater including a closure device, which comprises a controllable closure means.

- the coater blade 102 faces the building platform (not shown) and, with the adjustable diaphragm 103 (closure means), forms a coater gap 100 in which a pouring cone made of particle material 104 is formed to close the gap.
- the adjustable diaphragm 103 can be controlled by suitable means and the coater gap 100 can thus be opened further. In this way, for example, an increased amount of particulate material can be applied to the building platform (not shown) and the traveling speed of the coater can thus be increased.
- FIG. 1b shows the process of applying the particulate material, the coater being moved in the feed movement 108.
- the coater blade 102 (see FIG. 1 a) is set in vibration with a swinging movement 109, so that the pouring cone opens and particle material flows out and a roller made of particle material 107 is formed and an applied layer of particle material 106 is applied.
