POROLAY LAY-FOMM 40 by Kai Parthy / Lay-Filaments

This material is made from a rubber-elastomeric polymer and a PVA-component.

Product information

POROLAY is the name of a brand new series of 3D printer filaments. This new revolutionary line consists of foamy, felty filaments with a porous structure. With this filament you can build porous flexible objects.

The POROLAY line consists of four different types of filaments: LAY-FELT, LAY-TEKKKS, LAY-FOMM (40 & 60) and GEL-LAY. LAY-FELT and LAY-TEKKKS are similarly felt-like materials, though LAY-TEKKKS is thinner and more fibrous. LAY-FOMM and GEL-LAY are foamy and gel-like respectively. The composition of the POROLAY filaments consist of two different materials; a functional component, for example an Elastomer (i.e. a rubberlike) and a soluble component (e.g. PVA, sugar, salt, or soluble resins).

Note: the POROLAY filaments are specially designed for experimental use by experienced users.

POROLAY LAY-FOMM 40 is best characterized as foamy and highly porous. This material is made from a rubber-elastomeric polymer and a PVA-component. That means that part of this filament is water soluble. Once you rinse this material in water, the PVA component dissolves and the rubber polymer remains as your micro-porous object. LAY-FOMM 40 feels like soft rubber with holes and is therefore ideal for printing soft rubber-like objects, such as bendable suits and sponge-like objects, ink-reservoirs, bio-cells, micro-foam and elastics.

Your object printed with LAY-FOMM will feel strong and rigid but after rinsing the print with water the object becomes micro-porous & elastic. This makes it very suitable for printing soft and flexible rubber like objects. The LAY-FOMM 40 filament is very soft and has a shore hardness of A40, it is slightly softer than LAY-FOMM 60 which has a shore hardness of A60. For the best result of maximum flexibility of the printed object we recommend to immerse the print in a basin of tap water for 1 to 4 days.


Features of POROLAY LAY-FOMM 40 filament
- Optimal for printing soft rubber objects;
- Close to no warping;
- Shore hardness of A40 (slightly softer than LAY-FOMM 60);
- A heated bed is not necessary when printing with the LAY-FOMM 40;
- Printed objects are hot-sealable after drying;
- Micro-porous means micrometer-dimensions! Pores are not visible to naked eyes;
- Printed objects can be filled not only with water, try to use emulsions of oil, glycerin, inks, salty solutions, or ionic liquids to make it conductive;
- All the components of LAY-FOMM 40 are harmless and food safe. (FormFutura statement only)
