LAY-FOMM 40 is the newest innovation from the creator of LAYBRICK, LAYWOO-D3, and BendLay. LAY-FOMM 40 is a foamy material and is highly porous. LAY-FOMM 40 is part rubber-elastomeric polymer and part PVA. Once you rinse this material in water only the rubber polymer remains as your micro-porous and flexible object. We recommend printing LAY-FOMM 40 between 220°-230°C. However, remember that each printer is slightly different so you may need to increase or decrease the temperature by 5°C until your print looks perfect!
