WebAs we have mentioned, density is the relationship between mass and volume of something; in this case our 3D filament. We already have the mass of the filaments, since they usually come in coils of 1 [kg] of weight (minus the weight of the support). We only have to know the volume, and here comes the problem. If we consider the filament as if it ... WebSpecific gravity is expressed as a number. As the density of water at 4°C is 0.9999 g/cc and at 30°C is 0.9956 g/cc, it is so close to 1 through a range of temperatures that for … parkland breast center
