Formlabs is announcing a new version of its Castable Wax, that’s targeted toward jewelry designers and makers. Castable Wax 40 is, as the name implies, a 3D-printable resin made up of 40 percent wax, which can be used to create molds into which metal can be poured. The company says that the material behaves the same as traditional casting wax, which is used in a process known as “Lost Wax Casting.”
Rather than go it alone, Formlabs teamed up with Rio Grande and the Gemological Institute of America (GIA) to help develop the new wax. Rio Grande’s Scott Bradford said that traditional wax moulds aren’t great for things like class rings, where the lettering can present a unique challenge. By comparison, a 3D-printed material that behaves like wax enables designers to better create fine details in larger structures.
