Movement system for achieving movement of at least a nozzle assembly in an additive manufacturing machine

A movement system for achieving movement of at least a nozzle assembly in an additive manufacturing machine, the movement system comprising:

• a first tower configured to move back and forth along a first axis, wherein the first tower comprises at least three primary rods;
• a second tower configured to enable the movement of the first tower up and down along a second axis, wherein the second tower comprises at least three secondary rods;
• and
• a carriage system configured to enable the first tower to move back and forth, relative to the carriage system, along the first axis and to enable the first tower to move up and down the second tower along the second axis, wherein,
• the carriage system moves up and down the second tower along the second axis;
• and
• the carriage system defines a plurality of holes for at least one the primary rods and at least one of the secondary rods to pass through.

A movement system for achieving movement of at least a print plate in an additive manufacturing machine, the movement system comprising:

• a base tower configured to move back and forth along a third axis;
• and
• a belt assembly configured to enable the back and forth movement of the base tower along the third axis, wherein,
• the belt assembly comprises a belt, a gear and at least two bearings;
• the belt interfaces with the gear and the two bearings, with one bearing on each side of the gear, such that the belt is sandwiched between the gear and the bearings;
• the belt is engaged to the base tower;
• and
• rotation of the gear results in movement of the belt, and thereby the base tower, along the third axis.
