1.75 mm Lay-Felt Poro-Lay filamentLay Filaments
Poro-Lay is the new series of 3D printing materials with unique properties. The Poro-Lay material consists of two components, one is water-soluble. Poro-Lay has a porous material structure, thereby suitable for new applications.

Special filament with rubber, felt-fibers and soluble material (like PVA) in natural color.
For experienced user.
Poro-Lay is available in four different variants:
- Lay-Fomm 40
- Lay-Fomm 60
Lay-Felts has felt-like features, it contains stiff or soft felt-fibers. Lay-Felts results in bendable and felt-like, fibrous objects. Possible applications include membranes, filters, textiles or artificial paper. It is the bending-resistant variant of Poro-Lay materials.
- Felt-like and micro porous
- Partially water soluble
- Heated bed not required
- No warping
|Nominal diameter||1.75 mm|
|Printing temperature||220-240 °C|
All Poro-Lay materials are tough in its filament form. The Poro-Lay filament can be processed like PLA, heated bed not required. 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. 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.
How to rinse:
- Gently rinse with water, warm/hot water and patience provides good results.
- After one day the material is getting softer, after three days every PVA should be gone.
- Stir and change the water often.
- You can reduce the rinsing time by using an ultrasonic cleaner.
- Remaining water can be removed from the object quickly by using a clothes dryer.
- Repeatedly rinsing: fresh water → wait → dryer → fresh water → wait → dryer.
- PVA residues feel greasy, remove all PVA residues.
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 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.
Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider our tips as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
