Chemical curing of formulations with PEG-DA and up to 5% ( w/w) of the charged monomers was possible without difficulty. In this contribution, hydrogels based on poly(ethylene glycol) diacrylate (PEG-DA) and the charged monomers 3-sulfopropyl acrylate and trimethylammonium chloride are formulated for 3D printing, together with Poloxamer 407 (P407). However, new hydrogel formulations for 3D printing as well as a detailed understanding of crucial formulation properties for 3D printing are needed. Hydrogels are an interesting class of materials used in extrusion-based 3D printing, e.g., for drug delivery or tissue engineering.
