Resin and Polymer casing is a manufacturing process used to make copies of 3D objects or parts already in existence. The way this process works is that a mold is made, generally from a silicone material using the part being copied. Once the mold is made resins and polymers can then be poured into the mold making exact copies of the original part. Often times the process is great for making exact copies of 3D printed parts. Generally this process is used for low production and prototyping of parts.
