From sunglasses to bag handles, many fashion accessories and their constituent parts are made using traditional industrial moulds. These rigid, hollowed blocks are filled with a range of liquefied materials — like plastic, glass and metal — which harden, adopting the shape of the mould. Once created, moulds can be used to cost-effectively manufacture large runs of identical products. But because traditional moulds often cost thousands of dollars to make, they are less useful for limited-run or individualised products.
