Air-Permeable Mold-Quality Metapor Aluminum Sheets

Create vacuum-forming and thermoforming molds without vacuum channels or holes. The pores in Metapor aluminum evenly distribute a vacuum and release air and moisture, so bubbles and blemishes won’t form. You need to mill the aluminum to expose the pores.
