## Abstract

A manufacturing method for passenger door corner components of aircraft or spacecraft includes using additive layer manufacturing, ALM, to form an integral passenger door corner component. The integral passenger door corner component includes a substantially cruciform shape having a frame coupling member with two frame couplings as end pieces. The frame coupling member intersect with a beam coupling member with two beam couplings as end pieces.

## Claims

### Claim 1

A manufacturing method for passenger door corner components of aircraft or spacecraft, the method comprising:
using additive layer manufacturing (ALM) to form an integral passenger door corner component, the integral passenger door corner component comprising a substantially cruciform shape in a longitudinal sectional view having a frame coupling member with first and second frame couplings as end pieces extending in a first direction, the frame coupling member intersecting with a beam coupling member with first and second beam couplings as end pieces extending in a second direction substantially perpendicular to the first direction,
wherein one of the frame couplings and one of the beam couplings form a door edge which is rounded with a reinforcement rim formed around the inner edge, said reinforcement rim being integrally formed with the passenger door corner component and substantially extending in a longitudinal sectional plane of the passenger door corner component.

### Claim 2 (depends on 1)

The method according to claim 1, wherein ALM is performed using powder bed technology.

### Claim 3 (depends on 1)

The method according to claim 1, wherein ALM is performed using wire feed technology.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the integral passenger door corner component comprises a corner doubler in an angle opposite of the door edge.

### Claim 5

An integral passenger door corner component manufactured by a method comprising:
using additive layer manufacturing (ALM) to form an integral passenger door corner component, the integral passenger door corner component comprising a substantially cruciform shape in a longitudinal sectional view having a frame coupling member with first and second frame couplings as end pieces extending in a first direction, the frame coupling member intersecting with a beam coupling member with first and second beam couplings as end pieces extending in a second direction substantially perpendicular to the first direction,
wherein one of the frame couplings and one of the beam couplings form a door edge which is rounded with a reinforcement rim formed around the inner edge, said reinforcement rim being integrally formed with the passenger door corner component and substantially extending in a longitudinal sectional plane of the passenger door corner component.
