The utility model provides a three-axis moving mechanism for 3D printing, and relates to the technical field of moving mechanisms. A front-back moving assembly is fixed to the base. When the second motor is damaged and cannot work, the height of the printing head can be adjusted by controlling stretching and retracting of the two electric cylinders, and the problem that the height of the printing head cannot be adjusted due to damage of the second motor is solved; when the frame body slides back and forth in the two first rails, the sliding protrusions on the frame body can automatically collect dust and residues in the first rails to the cleaning holes and then discharge the dust and the residues through the cleaning holes, follow-up manual cleaning is not needed, practicability is high, and the problem that in the using process of an existing moving mechanism, the dust and the residues cannot be cleaned easily is solved. After being damaged, the motor for adjusting the height of the printing head can be continuously used after being maintained, so that time is wasted; and dust and residues are accumulated in the sliding rail after the sliding rail is used for a period of time, regular cleaning is needed, and operation is tedious.
