Metal 3D printer

A metal 3D printer comprising:

• a base unit comprising a fixed part, a first moving part disposed on the fixed part to move in a first direction, a second moving part disposed on the first moving part to move in a second direction, and a third moving part disposed on the second moving part to move in a third direction;
• a nozzle unit coupled to the second moving part to move in the first and second directions and move in the third direction and configured to inject a material for manufacturing a sculpture;
• a processing unit coupled to the third moving part to move in the first to third directions and configured to process the sculpture;
• a table unit disposed rotatably to the fixed part and disposed below the nozzle unit to allow the material injected from the nozzle unit to be seated thereon;
• and
• a heating unit disposed on the fixed part to move in the third direction and disposed below the table unit to heat the table unit,
• wherein the table unit comprises:
• a table part on which the material injected from the nozzle unit is seated;
• a support part configured to support the table part so that the table part rotates around the second direction;
• a first table driving part coupled to the support part and configured to allow the table part to rotate around the second direction;
• and
• a second table driving part coupled to the fixed part and configured to allow the support part to rotate around the first direction.
