Abstract

A method for providing a casing (11) for a prefabricated column (1) of chromatography column material in order to manufacture a chromatography column, wherein the casing (11) is generated by additive manufacturing, includes the steps of rotating the column (1) of chromatography column material with respect to a casing material feed in a manner to successively cover a casing surface (8) of the chromatography column material along a contact area path (12), and of arranging an amount of flowable casing material (9) at a current contact area (7) along the contact area path (12) at the casing surface (8) of the column (1) of chromatography column material in order to generate the casing (11) for the chromatography column by successively adding the solidified amount of casing material (9) at the contact area (7).
