POROLAY POROLAY is the name of a brand new serie of 3D printer filaments. This new revolutionary line consist 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.
LAY-FOMM 40 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.
We currently sell this revolutionary POROLAY LAY-FOMM 40 filament in coils of 250 grams.
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.
Recommendations for printing POROLAY LAY-FOMM 40 filament - Printing temp: between 220°-230°C; - For maximum flexibility rinse printed object in tap water for 1 to 4 days; - Shorten rinsing time by printing less walls/shells and less filling %; - Store filament dry / if wet after time > dry it in oven at 80° for some hours; - After drying printed objects will be hot-sealable.
