First of all, the safety factor of a good 3D printer is absolutely guaranteed. Pay attention to whether the product has been tested safely at the time of purchase!

Secondly, the accuracy of a good 3D printer is absolutely very high.

  Moreover, the stability of a good 3D printer is also very high, basically can run for 50 hours under high load, and the parts of the machine have no abnormalities, no looseness, no shaking, and the precision remains unchanged. During the printing process, the appearance of the chassis is basically the same as the room temperature, and no odor is floating out.

  In summary, a good 3D printer must have high security, stability, and print accuracy. Of course, the full-featured, simple operation is also the pursuit of more and more users.
