## Abstract

Additive manufacturing machine for creating a three-dimensional model from powder material, that consists of chassis (1), in which are located one below the other a loading system (4), system for applying powder material (2), system for applying fusing substance (3), container (5) with a removable bottom, fixating system (6) for the container (5), lifting system (7) for lifting and lowering the removable bottom of the container (5) and a control unit (9), which is located at the top end of the chassis (1). The system for applying powder material (2) and the system for applying fusing substance (3) are mounted on the chassis (1) in such a way as to be able to move on planes that are perpendicular to each other.

## Claims

### Claim 1

An additive manufacturing machine for creating a three-dimensional model from powder material, comprising:
a chassis, in which are located, one below the other, a loading system, a system for applying powder material, a system for applying fusing substance, container which includes a movable bottom, a fixating system, and a lifting system for lifting the movable bottom of the container,
a control unit, which is located at the top end of the chassis, and the system for applying powder material and the system for applying fusing substance being mounted on the chassis in such a way as to be able to move mutually perpendicular over one and the same plane, which is parallel with a layer of the three-dimensional model,
the system for applying powder material including a body and of two rolls that rotate in opposite directions, powered by two electrical motors, wherein the two rolls are separated by a separating plate and the rolls have grooves, from which the powder material is dosed, and one of the rolls works in a first direction and the other in a second, opposite direction.

### Claim 2 (depends on 1)

The additive manufacturing machine for creating a three-dimensional model from powder material according to claim 1, the system for applying powder material including a longitudinally vibrating part, which has a coating, the vibrating part being hung on elastic parts, allowing vibrations only throughout lengthwise direction.

### Claim 3 (depends on 2)

The additive manufacturing machine for creating a three-dimensional model from powder material according to claim 2, the vibrating part being linked to two elastic parts, to which an eccentric is connected and linked to an electric motor so the vibrations can traverse only throughout a lengthwise direction of the vibrating part.
