The GROWLAY filament from Lay-Filaments is a very interesting 3D printing filament that works as a growing medium. With this revolutionary material you can print objects and grow organic crops (grass, moss, etc.) on them. GROWLAY is a filament specially designed for use with the most popular desktop FDM 3D printers.

Main features

• The mold grows through the open-celled capillaries and forms a mycelium.
• Grass seeds can get trapped and grow in Growlay.
• The spores find space to germinate in small cavities. (see SEM photo)
• The roots cling to the structures of the object's fill.
  
  

GROWLAY works as a growing medium. You can add seeds or spores and they will grow on the 3D printed object. So this filament offers many interesting possibilities for experimentation!

Print 3D objects and let organic crops grow:

• grass; moss
• fungus; mold
• lichen
• mycelium
• pharmaceutical cultures, mother cells

GROWLAY works like fertile ground.

GROWLAY properties:

• GROWLAY is microcapillary. Its cavities absorb and store water, dissolved liquid nutrients or fertilizers. Promoted due to capillary action throughout the printed object.
• The mold grows through the open-celled capillaries and forms a mycelium.
• Grass seeds can get trapped and grow in Growlay.
• The spores find space to germinate in small cavities. (see SEM photo)
• The roots cling to the structures of the object's fill.
• Lichens also grow on Growlay. These usually grow preferentially on wall stones or trees.
• GROWLAY can be sterilized (for food and research use) with gas or wet (but not thermally)
• For color differentiation, objects printed with Growlay can subsequently be colored with food coloring.
• absorbent carrier for agents

GROWLAY is available in the functionally different white and brown versions

• The white version is an experimental and fully compostable filament
• The brown version contains not only pores but also embedded "food" in the form of cellular material necessary for growth
