[ 35 ] Ernst Engelke took up Kastenbaum's approach and developed it further with the thesis, "Just as each person's life is unique, so is their death unique.
Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
This is often referred to as flaying alive. There are also records of people flayed after death, generally as a means of debasing the corpse of a prominent enemy or criminal, sometimes related to religious beliefs (e.g., to deny an afterlife); sometimes the skin is used, again for deterrence, esoteric/ritualistic purposes, etc. (e.g., scalping).
