Item no: 0204613 weight: 1 kg 3d support filaments are the class of materials that come into play when you print 3d objects that have big overlaps . you cannot start printing something in the air if there is no anything underneath of the object. the wonderful solution for this problem has come to mind of one of 3d printing enthusiasts to use temporary material that would support upper layers during printing and would dissolve in water after objects are ready.
