Yes, the advancement in 3D printing technology has made it possible to 3D print concrete molds. For example, you can go for resin, silicon, or filament molding, which is a quite powerful production method that, when properly combined with the 3D printing technology, can help you in making multiple copies of a product or design. Just get the design that you want to give a shape, and your 3D printer will get it done. Creating concrete molds using a 3D printer may take around 1 to 2 hours, and the result will be very impressive.
