REC FLEX is a special flexible material, similar in properties to solid silicone. Elastic and pleasant to the touch. This material opens up new possibilities in 3D printing using FDM technology. Now you can print models with new properties: everything from toys, cosplay masks and soft slippers to elements of joints, buttons and special pneumatic branch pipes of complex shape. It can not be machined and therefore has a high wear resistance. It is bonded with synthetic rubbers or with a soldering iron. Each spool is packaged in a reusable vacuum bag with silica gel so that the plastic does not lose its properties when stored.
