Abstract: The present invention relates to a method for the preparation of a solid foam, wherein the method comprises depositing discrete units of a foam on a surface to obtain a first foam deposition, followed by depositing a wet foam between the discrete units to obtain a subsequent foam deposition, and drying the wet foam. The invention further relates to a solid foam comprising discrete units of foam embedded in a foam matrix.
