Abstract
A bonded helical compression spring. The spring includes a plurality of layers having successive wave crests and troughs. First crests and first troughs of a first layer are aligned with respective second troughs and second crests of an adjacent second layer and with respective third troughs and third crests of an adjacent third layer. The first crests of the first layer are bonded to the second troughs of the adjacent second layer and the first troughs of the first layer are bonded to the third crests of the adjacent third layer. As the crests and troughs of adjacent layers are bonded together, friction between the crests and troughs is eliminated.

A bonded helical compression spring comprising:
- a plurality of layers having successive wave crests and troughs, first crests and first troughs of a first layer are aligned with respective second troughs and second crests of an adjacent second layer and with respective third troughs and third crests of an adjacent third layer, the first crests of the first layer are bonded to the second troughs of the adjacent second layer and the first troughs of the first layer are bonded to the third crests of the adjacent third layer;
- wherein as the crests and troughs of adjacent layers are bonded together, friction between the crests and troughs is eliminated.
A one piece helical compression spring comprising:
- a plurality of layers having successive wave crests and troughs, first crests and first troughs of a first layer are aligned with respective second troughs and second crests of an adjacent second layer and with respective third troughs and third crests of an adjacent third layer, the first crests of the first layer are integrally formed to the second troughs of the adjacent second layer and the first troughs of the first layer are integrally formed to the third crests of the adjacent third layer;
- wherein as the crests and troughs of adjacent layers are integrally formed, friction between the crests and troughs is eliminated.
A one piece three-dimensionally printed helical compression spring comprising:
- a plurality of layers having successive wave crests and troughs, first crests and first troughs of a first layer are aligned with respective second troughs and second crests of an adjacent second layer and with respective third troughs and third crests of an adjacent third layer, the first crests of the first layer are integrally formed to the second troughs of the adjacent second layer and the first troughs of the first layer are integrally formed to the third crests of the adjacent third layer;
- wherein as the crests and troughs of adjacent layers are integrally formed, friction between the crests and troughs is eliminated.
