Abstract
A method for manufacturing a component in layers includes dropwise application of a liquid material using a printhead. More particularly, a layer (14) of the component to be produced is divided into an outer region (20) and a central core region (18), and the liquid material (16) is applied successively in the outer region (20) and the core region (18). One or more parameters relating to the spacing between paths to be traversed, the drop size, the spacing between successive drops, etc. is selected so that the layer (14) will have a thickness that is as uniform as possible.
Claims20
A method of manufacturing a component in layers by dropwise application of a liquid material using a printhead, the component including an overhang that extends in a layer of the component at a first angle (α) to a build-up direction, the method comprising:
- defining a contour of the component to be manufactured in the layer;
- defining an outer region of the layer that extends along the contour and a central core region of the layer that is surrounded by the outer region;
- dropwise applying the liquid material with a first average droplet diameter (dcore) in the core region along multiple parallel core paths that have a first spacing (DLV,core) from each other;
- and
- dropwise applying the liquid material with a second average droplet diameter (dhull) in the outer region along one or more outer paths parallel to the contour, wherein a second spacing (DBH) between an outermost one of the outer path(s) and the contour in the layer is increased proximal to the overhang by a compensation spacing (Δ) that is based on the first angle (α).
