Dental labs and orthodontists are able to use 3D printing to improve the lost-wax technique: molds are built around a 3D printed version of the desired object (a dental crown for example) using a special casting resin or wax. The mold is then heated in order to melt the wax object (”lost wax”) and obtain an impression of the exact shape of the desired dental appliance. The final product is then made by casting a liquid material in the mold.
Essentially, this amazing machine can create a 3D printed version in casting resin of the desired dental appliance. This produces a custom mold which then can be used to cast the final product.
