REC RUBBER - rubber for 3D printing. Special material, which is very close to real rubber properties, repeating all its properties. The material is very well suited for printing: buttons, seals, shock absorbers and even tires for radio-controlled models! 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.
