Summary:Many materials (e.g., PVDF) are difficult to use in additive manufacturing processes because the material does not bond to the build platform of additive manufacturing machines. In order to use such materials, a build platform can use a difference in air pressure to hold a base film in position on a top plate of the build platform. An object is to be printed using the material and the base film is of a material that the material will bond to during the printing process. The difference in air pressure may be achieved using a build plate with a voided internal region and a top plate with apertures. A low pressure source can draw a vacuum in the voided internal region. Placing the base film over the apertures causes the base film to be held in place by the difference in air pressure.
