Abstract
A platform assembly has a rigid support with an array of threaded passages extending therethrough; threaded posts are engaged in the threaded passages and extend above the rigid support by a distance adjusted by rotation of each threaded post in its associated threaded passage. Manually-adjusted dog point screws can provide the threaded posts, and self-locking nuts can provide the threaded passages. A platform of smooth, slightly flexible material extends over the threaded posts and has an array of mounting elements that magnetically attach to the threaded posts to hold the platform tightly against the end of each post. Adjusting the positions of the threaded posts serves to adjust the precise position and flatness of the platform surface relative to the rigid support, and with respect to a print head of a 3D printer in which the rigid support is incorporated.
