Disclosed is a coater 10 for a 3D printer, comprising an elongated container 30 comprising two opposing long side walls 32, 34 between which an internal cavity 36 is formed for receiving particulate material, the cavity 36 opening into an elongated output slot 38 for outputting the particulate material from the container 30 onto a construction field, and a first adjusting device 50 configured to move the two long side walls 32, 34 relative to each other at least in a respective lower portion 32a, 34a thereof adjoining the output slot 38 to thereby variably adjust the width of the output slot 38.
Disclosed is a method of manufacturing at least one component by 3D printing on a construction platform provided with a heating device, the method comprising: applying a layer of loose particulate material to the construction platform, heating the applied layer of loose particulate material by means of the heating device of the construction platform, outputting a liquid treatment agent onto a partial area of the heated layer of loose particulate material, and repeating said steps to build up the at least one component in layers. The heating by means of the heating device of the construction platform is carried out in such a manner that a temperature of the construction platform increases toward a predetermined construction platform maximum temperature during the build-up of the component to set a surface temperature of the respectively last applied layer.
