Description
To follow this project from its beginning to today, follow this link which will take you to the corresponding topic in the forum "lesimprimantes3D.fr" : "lesimprimantes3D.fr"
System using a printed triple helix spring and allowing the printing of high parts despite a low contact surface with the bed without buying parts. This system is mounted in place of the original feet.
The head of the spring is hemispherical for greater freedom of movement
The efficiency of the system is better if the springs of the bed have been replaced by a fixed height adjustment with nuts.
In fact, saccades at a height greater than 300mm generate vibrations which, without a damping system, generate geometrical defects.
The "Dew-Dew" pods prevent the vibrations of the machine from coming into resonance.
Example with the original pods on a piece of 400mm height (print speed 60mm/s):
Here on video, shock buffered by the "Dew-Dew" pods:
And here is a 400mm high piece printed with the "Dew-Dew" pods:
It can be seen that vibrations causing geometric defects are better absorbed.
Test performed with a print speed of 60mm/s
For a perfect result, it is necessary to reduce the speed from 300mm of height to max 30mm/s
