Gel-Lay is a new filament having a similar function to gelatin. This new filament is part of the new line of sparkling filaments (with a porous structure) called PoroLay. Composition of the filaments of the line PoroLay consist of two different materials; on one hand a functional component (TPE-elastomer) and the other a soluble component (PVA).
PoroLay line consists of four different types of filaments: LayFomm 40, LayFomm 60, FeltLay and Gel-Lay. (The first three have a foamy appearance and the last one gelatinous). Gel-Lay filament consists of a mixture of a PVA (soluble) and elastomeric rubber polymer. Therefore, part of this strand is water soluble. After rinsing the material in water, PVA component is dissolved and the rubber polymer remains a micro-porous appearance. As a gelatinous material (hence its name) offers multiple applications in the world of 3D printing to create soft objects. This duality between elasticity and water solubility of a part makes it an extremely versatile filament, being very suitable for use in biomechanics and objects in contact with water (especially designed for floating objects).
The printed object with Gel-Lay will be strong and rigid filament (although slightly flexible), but after wetting it with water becomes elastic object (micro-porous). Gel-Lay is one of the newest experimental strands today of 3D printing. This is the most innovative creation of Kai Parthy (creator of filaments as well known as the LayBrick, LayWoo-D3 or Bendlay among others). Gel-Lay filament is optimal for printing objects soft rubber due to deformation of negligible when printing. Importantly, the pores are not visible to the naked eye. Printed objects with Gel-Lay can moisten with water plus a multitude of liquids such as oil, glycerin, inks, saline solutions, ionic liquids or to be electrically conductive.
