Method for producing a medical instrument by way of an additive method

A method for producing a medical instrument, includes producing, by cutting material from a semi-finished product, a shaft including a clamping region and at least part of a head including cutting edges; additively generating at least part of the head of the instrument; performing the additively gen...

Zusammenfassung:	A method for producing a medical instrument, includes producing, by cutting material from a semi-finished product, a shaft including a clamping region and at least part of a head including cutting edges; additively generating at least part of the head of the instrument; performing the additively generating with a rotation axis of the instrument aligned vertically; reworking at least part of the head with a subtractive method; and using the subtractive method to perform at least one chosen from sharpening cutting edges and improving concentric running of the instrument.
