14 DAY TRIAL // Metal 3D printers are pretty rare, but the ones that do exist have been quick in spreading their wings, seeing as how prospective buyers proved quite eager to use them after they proved themselves.
The metal 3D printer that tire makers have become fairly enamored with is the ProX Direct Metal printer from 3D Systems.
The printer is being used to make new, more intricate treads, which would be impossible to make normally.
And that's in addition to being an altogether faster production process than the regular molding and assembly lines (machining and injection moulding).
Tire stripes go a long way in ensuring balance, traction on wet surfaces, and stability on dry surfaces. 3D printing technology allows for the production of treat moulds that let tie manufacturers test multiple designs before finally mass-producing a new tire. The ProX 300 is a particularly popular metal 3D printer for this process.
Fully dense metal parts with thinner walls, sharper edges, and more complex internal venting features (among other details) can be implemented via direct metal 3D printing. Such are the benefits of building things micro-drop by drop.
All in all, metal 3D printers are allowing for the creation of tires that provide drivers with better control and traction, and, thus, better auto safety.
