Abstract: Provided is a build mat to which a 3D print sticks well and from which the 3D print is easily separated. The build mat provided by this invention comprises a substrate and a surface layer provided to the first face of the substrate. The build mat has a peel strength of 1.5 N/18 mm or greater and 10 N/18 mm or less, determined by peeling the mat from polylactic acid (PLA) placed on the surface layer; and it is constituted so that the surface layer remains on the PLA in the peel strength measurement.

Abstract: A film contains a β-1,3-glucan derivative obtained by introducing an acyl group into a β-1,3-glucan and at least one resin selected from the group consisting of a rosin-based resin, a terpene-based resin, and a petroleum-based resin. The acyl group is represented by RCO—, and the R is a hydrocarbon group having 1 or more and 5 or less carbon atoms. Parts by weight of the resin with respect to 100 parts by weight of the β-1,3-glucan derivative are 90 parts by weight or less. A pressure-sensitive adhesive tape includes the film and a pressure-sensitive adhesive layer.
