Poro-Lay is the new series of 3D printing materials with unique properties. The Poro-Lay material consists of two components one of it is water-soluble. Poro-Lay has a porous material structure, thereby suitable for new applications. Print soft and porous objects with Poro-Lay
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)
Lay-Fomm 60 (~ Shore A60) for slightly bending-rigid objects from a Lay-Fomm 40th
Poro-Lay are experimental filaments for experimental and experienced user. Help for processing and a great ideas for new 3D objects can be found in forums.
The components of Poro-Lay are harmless and food safe. The water-soluble component is even biocompatible. However, we strongly advise not to eat the material.
Poro-Lay is best stored dry. If the material absorbed moisture after some time, the filament can be dryed in an oven at about 80 ° C for four to five hours. We recommend to dry the filament before the very first print.
