Kai Parthy, inventor of the original Laywoo-D3 and Laybrick filaments, is back with an exciting new material for desktop filament fabricators. An extension of his foam PORO-LAY line, Kai has developed a sponge filament he calls Layfomm. Though objects printed with Layfomm are pretty ordinary and stiff, upon initial printing, when they’re dipped in water for two to three days, they become soft and flexible.
Kai tells me that his Layfomm 40 Filament demonstrates a unique material property called Viscoelasticity that “is very rare and never seen in 3D-printing”. Viscoelasticity, according to Wikipedia, is capable of both viscous and elastic characteristics when it is reshaped or deformed. On the one hand, viscous materials, like honey, resist stress and strain.…
