Abstract
A method of manufacturing a safety valve chamber housing can include depositing a chamber housing material, and thereby gradually building up the chamber housing and forming a chamber in the chamber housing enclosed by the chamber housing material, the chamber being bounded by only a single solid structure of the chamber housing. A safety valve can include a piston, and a chamber housing having a piston bore and a chamber formed therein, the piston bore being in communication with the chamber, the chamber being enclosed by only a single chamber housing material. A well system can include a safety valve connected in a tubular string, the safety valve including a chamber housing with a chamber in communication with a control line, inner and outer walls of the chamber housing being made of a continuous chamber housing material.
