Ditch the threaded rod in your RepRap 3D printer and upgrade to a lead screw z-axis
provided 3D printable files and a detailed walkthrough for upgrading the Z-axis of a Prusa i3 RepRap 3D printer with a lead screw. Not for the first time and certainly not for the last, it would seem that a round of applause is due for aninanimate rod. Many cheap and cheerful DIY 3D printers, such as the Prusa i3 and other RepRap machines, use a threaded rod for their z-axis. The threaded rod is a cheap piece of equipment, but many users—Daniel included—have encountered irresolvable problems when using the oblong piece of metal. Use of a threaded rod as the z-axis of a 3D printer is standard for many budget machines, but notable problems include backlash and wobble, which can be eliminated with the use of a lead screw.
Steel Dynamics to Acquire Vulcan Threaded Products to Expand Finishing
"During 2015, we identified the pursuit of higher-margin downstream business opportunities that utilize our steel products in their manufacturing processes, as one of our target growth objectives," stated Mark D. Millett, President and Chief Executive Officer. "A strategy intended to reduce volatility during both strong and weak market cycles, given steel raw material supply optionality. During weak steel demand environments these businesses could purchase steel internally from our own mills, thus increasing SDI's steel mill utilization. As a consumer of special-bar-quality products currently produced at our Engineered Bar Products Division, Vulcan depicts this model perfectly and fits well within our core operating strengths."
