Good day, this is my first post/question in this forum. I would like to create a human equivalent tissue 3d model, for which I need -in principle- a material with a density similar to water, and also light chemical elements (Hydrogen, Oxygen, Carbon, etc.) to be atomically equivalent to a biological tissue. The technical specifications for the transparent resin, standard resin and ABS are very detailed from the mechanical point of view, however I have not been able to find the chemical composition to decide which filament would be better for my purposes. My 3d printer uses a 2.85 mm filament.
Any feedback is highly appreciated.
