 | Engineer's Toolbox: How to pin a shaft and hub assembly properly
One of the primary benefits of using a coiled spring pin to affix a hub or gear to a shaft is the coiled pin's ability to prevent hole damage. Another is the coiled pin absorbs wider hole tolerances than any other press-fit pin. This translates to lower total manufacturing costs of the assembly. However, there are a few design guidelines that must be adhered to in order to achieve the maximum strength of the pinned system and prevent damage to the assembly.

 | Micro-AM tech makes plastic 3D-printed parts conductive
Horizon Microtechnologies' new micro-AM technology can help in the elimination of electro-static discharge (ESD) in applications that would benefit from 3D printing by combining precision polymer additive manufacturing and ESD compliancy. Parts can be made with a controllably conductive surface coating and also coated internal channels with multiple bends. In one use, very compact and high-performance end-effectors were created for vacuum pick-and-place devices that were conductive enough to prevent electrostatic discharge.

 | Lithium-air battery could offer much longer EV range
A new and safer battery, tested for a thousand cycles in a test cell, can store far more energy than today's common lithium-ion batteries. More importantly, the battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range.
