The LayFomm 40 is another 3D printing filament created by Kai Parthy, the creator of such filaments as LayWood, Lay Brick and Reflect-o-Lay. LayFomm 40 filament is a 3D printing material with two components: an elastomer similar to rubber (TPU) and a water-soluble (PVA). After printing, place the item in water. After one to four days water-soluble (PVA) component dissolves. As a result, we received a very porous and flexible object that looks like foam. LayFomm 40 is slightly softer than LayFomm 60.
Print at 220oC – 230oC.
