 | Top Tech Tip: Seal it, protect it!
A Smalley Laminar Seal Retaining Ring is a metallic labyrinth seal consisting of multiple rings in a groove. To seal an assembly from contamination while withstanding high temperatures and corrosive environments, Laminar rings are produced from metal, not rubber, neoprene, or other non-metallic materials. The arrangement of the rings and the specific orientation of the rings are dictated by the application and the severity of the environment. Numerous configurations are available.

 | Design Tips: Fasteners for printed circuit boards
When specifying hardware for printed circuit board applications, many designers may still turn either to loose fasteners or broaching fasteners. While both provide the necessary functionality, each carries potential risks that may impact the production process, the integrity of boards, and even disassembly if required. Leon M. Attarian of PennEngineering runs through profiles of the latest surface-mount fastener families.

 | Chairless exoskeleton solves long-standing problem
The Chairless Chair is a new innovation for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. Operating a switch on the strap turns the flexible construct into a stable seat. Two small FAULHABER DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

 | Plastic alternative to metal: Delrin
One of the more popular plastic material choices Proto Labs offers for injection molding and machining is Delrin acetal homopolymer (Polyoxymethylene POM). Delrin works as an excellent replacement for metal because of its high tensile strength, low friction and high wear resistance, creep and warp resistance, and overall durability and toughness. Ideal for industrial applications, Delrin exhibits low moisture absorption and is chemically resistant to hydrocarbons, solvents, and neutral chemicals.

 | Automated measurement inspection cobot system
New Scale Robotics has introduced its Q-Span Automated Small-Part Measurement Systems for quality control (QC) teams in high-mix, small-batch manufacturing environments. Q-Span Systems combine robotic pick-and-place with automated measurement of small parts, automating the tedious manual process of measuring parts with digital calipers. A Q-Span Workstation Solution includes up to three gripper/caliper tools on one collaborative robot. The system picks up small parts, measures multiple dimensions, makes in-process decisions based on measurements (pass/fail or sort by range), and places each part in the appropriate tray or bin. All data can be recorded to a PC for later analysis and statistical process control (SPC).

 | Beats like the real thing: Hybrid bionic heart
Engineers at MIT and their partners have developed a bionic heart that offers a more realistic model for testing artificial valves and other cardiac devices. The device is a real biological heart that has had its tough muscle tissue replaced with a soft robotic matrix of artificial heart muscles that resemble bubble wrap.

| | Videos+: Technologies and inspiration in action | Will it vibe? 3D-printing shock and vibration test
The engineers over at Xometry have set 3D-printed parts on fire, pushed and pulled them to their limits, and even tried to smash them up. Now they take a look at how much continuous vibration nine 3D-printed test samples can withstand. Watch their latest engineering challenge to see which 3D-printed processes and material combinations will pass the test.
