Method for dual production of small-scale products

摘要

The invention relates to a method for manufacturing products by applying material at least partially in layers to form a structure, in particular by selective laser melting (SLM), said method comprising the steps of: (a) providing a base plate, (b) applying a layer of a curable material, (c) selectively curing predetermined zones of the applied layer on the basis of geometrical data of the product, (d) repeating steps (b) and (c) until the geometry of a first partial volume of the product has been created in the form of a cured material and (e) removing the uncured material. According to the invention, a reference mark is provided, the unit formed by the base plate and the first volume zones is clamped into a specific position by means of the reference mark and the respective second partial volume of the respective product is cut from the base plate, preferably by machining, in particular CNC milling.

1. A method for manufacturing products by applying material at least partially in layers, in particular by selective laser melting, said method comprising the steps of:
(a) providing a base plate made of the same material as the product, (b) applying a layer of a curable material, (c) selectively curing predetermined zones of the applied layer on a basis of geometrical data of at least two separate products by said selective laser melting, (d) repeating steps (b) and (c) until a geometry of a respective first partial volume of the respective product has been created in a form of cured material, (e) removing a portion of the material that has not cured,  wherein a respective second partial volume of the respective product is formed as a volume zone of the base plate and, further comprising the steps:
providing a reference mark,clamping a unit formed by the base plate and the first volume zone into a specific position by means of the reference mark,cutting the respective second partial volume of the respective product from the base plate, preferably by machining, in particular by CNC milling, wherein the products comprise one or more tooth replacement parts, and that the respective second partial volume of one or more of the tooth replacement parts comprises occlusal product segments, in particular masticating surfaces.
