How Are Lead Screws Used in a 3D Printer?

With a 3D printer, product developers can quickly and cost effectively create actual physical parts of product designs directly from product design data. Just as a desktop printer produces type on a 2D page, a 3D printer builds a physical object in 3D space, layer by layer.

How Plastic Acme Nuts Resolve Lead Screw Challenges

While lead screws provide cost, performance, and dependability advantages for many of today’s linear actuation requirements, some motion control applications present challenges that require the use of plastic acme nuts, which are engineered to provide internal lubrication, to make lead screws operate more smoothly, quietly, and reliably.

How to Evaluate Acme Screw Assembly Loads

Configuring an acme screw assembly that will not only perform but endure the demands of a linear motion application, requires a thorough understanding of the load requirements. Evaluating your loading conditions extends beyond the load that you want to move and the distance that you want to move it - it includes the effects of your application on the screw assembly itself.
