Abstract

An additive manufacturing machine is provided which can smooth out powdered material while preventing mechanical interference between a smoothing plate and a manufacturing box. The additive manufacturing machine has a support stage, a manufacturing box, and a powder feeder mechanism. The powder feeder mechanism feeds powdered material onto the support stage and smooths out the powdered material. The powder feeder mechanism has an arm portion, a guide mechanism, a connective portion, and a drive mechanism. The guide mechanism is secured to the manufacturing box and supports the arm portion such that it can move in a first direction. The connective portion is connected to the arm portion and transmits force to the arm portion only in the first direction. The drive mechanism is secured to a support member different from the manufacturing box and has a drive portion for moving the connective portion in the first direction.

Claims23

Dependent claims

An additive manufacturing machine comprising:

a support stage on which a powdered material for manufacturing a three-dimensional object is stacked as layers;
a manufacturing box having a cylindrical portion on which the support stage is slidably disposed;
and
a powder feeder mechanism for feeding the powdered material onto the support stage and smoothing out the powdered material;
wherein the powder feeder mechanism comprises:
an arm portion to which a smoothing plate for smoothing out the powdered material is fixedly secured;
a guide mechanism secured to the manufacturing box and supporting the arm portion such that the arm portion can move in a first direction that is parallel to one surface of the support stage which defines a working surface;
a connective portion connected to the arm portion and transmitting mechanical force to the arm portion only in the first direction;
and
a drive mechanism secured to a support member different from the manufacturing box and having a drive portion for moving the connective portion in the first direction.
