Description:
[Material] The 3D printer heated bed spring is made of steel, which is wear-resistant, sturdy, durable, not easy to break, and harder than ordinary springs, which helps to stabilize printing.
[Function] These compression springs are designed to replace the original springs in the printer bed, avoiding the need to level the bed before each print, providing more tension and stability, and making bed leveling more precise and firm.
[Installation] Use a spring compressor to compress the spring to a length suitable for installation, then place the spring at the predetermined installation position, use screws, nuts, and other fixings to fix the spring at the installation position firmly, and finally slowly release the spring compressor.
[Wide Application] It is suitable for most 3D printer heated beds, as well as automobiles, electrical appliances, instruments, and more.
