Tech Tip: How to create high-quality STL files for 3D prints

Have you ever 3D printed a part that had flat spots or faceted surfaces where smooth curves were supposed to be? You are not alone, and it's not your 3D printer's fault. According to Markforged, the culprit is likely a lack of resolution in the STL file used to create the part.

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.

What's so special about wave springs?

Don't settle for ordinary springs. Opt for Rotor Clip wave springs. A wave spring is a type of flat wire compression spring characterized by its unique waveform-like structure. Unlike traditional coil springs, wave springs offer an innovative solution to complex engineering challenges, producing forces from bending, not torsion. Their standout feature lies in their ability to compress and expand efficiently while occupying up to 50% less axial space than traditional compression springs. Experience the difference Rotor Clip wave springs can make in your applications today!

Clever! Indexing plungers with chamfered pins

JW Winco has developed a new type of indexing plunger -- GN 824 -- that can independently latch into edges and grooves. This is made possible by a chamfered plunger pin. When the chamfered pin encounters a raised latching geometry, it retracts and then springs back out again once it reaches the latching point. This new indexing plunger can be ordered with axial thread for fastening and a black plastic knob for operating the indexing plunger. In a clever design, the plunger pin can be adjusted by 360 degrees to ensure that it encounters the mating surface perpendicularly. This hardware is well suited for transport frames, mechanisms, or covers that need to be locked in place quickly and securely, especially without the need for manual intervention.

GE opens first new manufacturing operation in Louisville, KY, in over 50 years

GE Appliances celebrated the official opening of its GeoSpring Hybrid Water Heater manufacturing facility at Appliance Park in Louisville, KY, on Feb. 10 – the first to open there since 1957. The $38 million investment in the new product and a revitalized facility is the first milestone in commitments GE has made since 2009 to invest a total of $1 billion ($800 million in Louisville) and create more than 1,300 new jobs in the U.S. by 2014. The new product and other recent investments at Appliance Park have also created hundreds of highly skilled salaried jobs in fields like engineering, industrial design, and manufacturing.

Lean manufacturing and a more competitive wage structure for new employees led to the selection of Louisville as the production site for the new water heater instead of China, where an earlier version of the product was made. Not only can the new product now be made more competitively in the U.S., the GeoSpring Hybrid Water Heater, developed by the Louisville team, has an enhanced feature set, offers better performance with greater energy savings, and will be more affordable for consumers, according to the company.

The GeoSpring has the distinction of being the first GE Appliances product designed and built using Lean manufacturing principles. The Lean process, which uses a cross-functional team of employees – including hourly manufacturing workers – to design the product and the manufacturing process, will aim to increase the competitiveness of the operation by identifying and removing waste in materials and work effort often found in traditional manufacturing.

State and local governments also supported putting the new GeoSpring in Louisville, with up to $17 million in incentives to design and build the new energy-efficient facility and other investments that the company will make at Appliance Park during the next several years.

About the GeoSpring
The new GE GeoSpring Hybrid Electric Water Heater is designed to provide hot water in the quantities homeowners have come to expect from a 50-gal tank water heater, but uses less than half the energy to produce it. Compared to a conventional 50-gal tank water heater that uses 4,879 kW per year, the new GE GeoSpring Water Heater:

• Uses less than half of that energy – or about 1,830 kW per year.*
• Saves approximately $325 per year, less than half the cost of a conventional electric water heater — that's $3,250 in savings in energy costs over a 10-year period based on 10.65 cents per kW.

The GeoSpring Hybrid Water Heater combines energy-saving heat-pump technology with traditional electric heating elements. Hybrid technology absorbs heat in the ambient air and transfers it into the water. Since this requires much less energy than the energy used to generate radiant heat – as used in a conventional electric tank water heater – the GeoSpring Hybrid Electric Water Heater is more economical to operate, according to its maker.

GeoSpring will be available in March at national retailers such as Lowe's and Sears and national plumbing distributors such as Ferguson, as well as many local retailers and distributors. For more information on features and availability visit GEAppliances.com/american-made-water-heater/.

*Based on DOE test procedure and comparison of a 50-gal standard electric tank water heater using 4,879 kW per year vs. the GeoSpring Hybrid Water Heater using 1,830 kW per year.
