Resin casting from 3D printed molds is a practical production method used for low-volume production for industrial prototypes, dentistry, and ready-to-market custom products like jewelry, collectibles, and designer toys. The low level of initial costs, repeatability, and design freedom were crucial factors for a designer to choose 3D printed molds to create a series of everyday objects. To print the mold boxes, the designer used ZMorph VX Multitool 3D Printer.
The 3D printed mold boxes were used to create silicone mold negatives for casting objects. The quality of the silicone mold negatives affects directly casted objects. To ensure the best results the designer smoothens the printed mold boxes internal surface. That way, she gets rid of all cracks and unwanted features that could damage the silicone molds. Afterward, the mold boxes were sprayed with mold release and filled with silicone. Usually, it takes around 24 hours for silicone to cure. Once cured, the silicone molds were filled with translucent epoxy resin mixed with small black and white stones. In the end, designer applied post-production techniques to smoothen the surface of the casted objects resulting in a series of products ready to sell.
The objects cast from resin 3D printed molds are ready to market and sell. The molds, which were printed in hours, significantly cut the production time and can be used to make several copies of the product. The low cost, short time, and high-quality results are proof of concept that 3D printed molds are now an option for low-volume manufacturing of ready-to-market high-quality objects.
