Definitions
- the invention relates to a method for the additive manufacturing of components, in which a component is produced by depositing at least one material in the form of drops. It therefore falls within the field of additive manufacturing and is also suitable for the production of components that are made with several different materials, such as composite components.
- the drops can be deposited drop by drop from nozzles or by a pressure device, so that a three-dimensional component can be obtained after curing or sintering.
- the drops are arranged in layers next to and/or on top of one another.
- the surface is smoothed immediately after individual drops have been deposited using the energy of a laser beam, the focal point of which is directed at elevations formed on the drops.
- the focal spot of a laser beam is therefore immediately after placement and before further processing, in particular drying, hardening, fusing or sintering, is carried out.
- the smoothing can be done in such a way that
- a removal of material can preferably be achieved by ablative means or by sublimation.
- a locally defined temperature increase can therefore be used, with which the material from drops reduces the depth of and the volume in depressions by flowing the material and thus creates a surface
- the material formed with the drops can be a polymer and/or
- a suspension containing solids can be used.
- a suspension can be mixed with a liquid containing solid particles or fibers and at least one organic binder be educated.
- a viscosity and surface tension should be maintained at the respective processing temperature while the droplets are being deposited so that droplets can form and no material can flow away.
- a removal of material and/or a flow of material can be used to at least partially fill depressions after drops have been deposited in at least one layer for the formation of a respective
- material can be removed from elevations and/or flow in the area around depressions in a controlled manner.
- the surface topography can be recorded with at least one optical sensor and height values recorded with spatial resolution, the deflection movement of the focal spot of the laser and preferably also the power density in the focal spot of the laser beam can be influenced.
- the deflection movement of the focal spot can be achieved by a relative movement of the laser beam with its op
- the laser beam can also be deflected accordingly with suitable optical elements and, if necessary, additionally shaped.
- the position of elevations and depressions can be determined and thus the deflection movement of the one- or multi-dimensional on respective elevations for material removal and/or in areas around wedge-shaped depressions with so-called scanners
- BO can be carried out on-line.
- the surface topography in particular can be determined and used for the control.
- temperature determination in the In the area of the focal spot the dwell time at a position, the power density in the focal spot, and the size of the current focal spot area can also be specifically influenced. This is not only advantageous when material is removed. It can also be used to influence the respective favorable temperature in the area of the droplet material, which leads to flow and thus to filling of depressions with associated smoothing of the surface.
- the temperature should be spatially resolved or determined selectively in order to be able to carry out a locally defined control.
- green processing can be carried out directly by means of laser ablation or by causing it to flow.
- the surfaces can be smoothed with a significant reduction in surface roughness.
- contour elements in the order of ⁇ 50 pm instead of ⁇ 500 pm can be formed with the locally defined material removal.
- a direct integration of green processing is possible by processing all surfaces, including the internal surfaces of the respective component.
- the processing immediately after depositing the first material without a large delay in time enables the boundaries between different individual drops that have been deposited and possibly different materials to be designed more precisely if drops made from different materials have been deposited.
- a significantly improved surface quality and interface geometry at the boundary surfaces of droplets can be formed with little additional effort caused by the integration of laser processing.
