Print soft and porous objects with Poro-Lay
Poro-Lay is the new series of 3D printing materials with unique properties. The porolay material consists of two components one of it is water-soluble. Poro-Lay has a porous material structure, thereby suitable for new applications.
The Poro-Lay filament can be easily processed like PLA. The printed object is hard first. After printing, the material is placed in water, preferably one to four days in soapsuds. The thinner the object, and the less filling, the shorter the rinsing time. Now ingredients dissolve and the porous structure remains. The micropores are so fine (micron) that it can not be detected with the naked eye.
If the printed object is inserted in liquids other than water, the material properties can subsequently be modified. Through the use of ionic or saline solutions, the material may be made electrically conductive. Also interesting is the use of inks or oils.
Poro-Lay has so vanishingly little delay, almost no warp, it can also be processed without heated printing plate.
All Poro-Lay materials are tough, shatter-resistant in its basic form, and can be printed with all commercially available FDM / FFM printers (RepRap).
The material properties (fibrous, felt-like, gel-like) are highly dependent on the moisture content and humidity. After drying, the objects are harder than in water in which they are much more conformable and soft. This is due to the water molecules in the pores, which reduce the friction.
Poro-Lay is available in four different variants:
- Lay-Fomm 40 and Lay-Fomm 60 produces soft, elastic and flexible objects, similar to rubber, foam or sponge. It is available in two hardnesses. Lay-Fomm 40 for soft objects (~ 60 Shore A) and Lay-Fomm 60 (~ Shore A60) for slightly bending-rigid objects from a Lay-Fomm 40th
- Lay-Felt - results in felt-like, fibrous objects. Possible applications include membranes, filters, textiles or artificial paper. It is the bending-resistant variant of Poro-Lay materials.
- Gel-Lay - for gelatinous, soft objects. When wet, very glibbrig and soft when dry, it is stable, not very elastic but flexible. For example, for objects in aquariums.
