When flexibility is what you want!

FLEX is a highly flexible filament, unique in our range.
This material stands out because of its enormous mechanical strength and excellent resistance. This to both chemicals, extreme temperatures and UV rays. This BIO version of thermoplastic co-polyester has a high carbon content of renewable materials. Good news, since this results in a lot less environmental impact. FLEX is often used as a rubber replacing filament for 3D printing.
