The FRESH method (Freeform Reversible Embedding of Suspended Hydrogels) offers the advantage to create embedded complex tissue scaffolds, which are quite soft, from hydrogels which feature a high similarity to native tissues and organs. Up to now size ranged between a few millimetres to a few centimetres, but now the range could be expanded to a full-size model of a human heart. MRI scans from a patient's heart were used to create the organ copy made of alginate. The model mimics the elasticity of real cardiac tissue, while it is stable enough to perform suturing. The method can be used in surgeons' and students' education as well as for pre-surgery planning.
