In this work fused deposition modeling (FDM) based 3D-printing is used for the manufacturing of cartridges for solid phase extraction. The novelty of the approach is that the 3D-printing is used for the simultaneous printing of the porous retentive bed, the cartridge housing and wall as a single printed monolith. This process allows for enhanced freedom in the used cartridge format, shape and dimensions as compared to the conventional packed bed formats. Cartridges were printed by polylactic acid (PLA) and polypropylene (PP), whereby the latter currently appear the most promising in terms of applications with emphasis on environmental analyses. Cartridges were optimized in terms of strut orientations, pore size, wall thickness and bed length. The obtained performance was tested with e.g. 16 priority polluting poly-aromatic hydrocarbon, illustrating that large aqueous volumes of PAH solutions can be loaded and eluted in fairly narrow plugs also on these alternatively manufactured SPE cartridges.
