 | CNC machining case study: One-of-a-kind computer chassis
Learn how Josh Sniffen, the YouTuber behind the popular PC-building channel "Not From Concentrate," trusted Xometry to provide a wide range of manufacturing options, personalized Design for Manufacturing (DFM) feedback, and order management support for his latest creation: the HEXO ATX computer chassis. All in all, Sniffen procured parts using Xometry's CNC machining service, selective laser sintering 3D-printing service, and sheet metal cutting and fabrication services. A neat insider look at the process.

 | Filter fans for enclosures: 70 models in new series
The new 4000 Series from Seifert Systems covers 70 UL-listed filter fan models designed for enclosure applications. They snap in place once a cutout is made in the enclosure. Mounting screws are available with EMC models or as an option. Filter media snaps in place and easily slides out for replacement. When used with a Seifert thermostat, 4000 Series filter fans can be turned on only when needed. Air flow ranges from 7 to 483 cfm.

 | Top Tech Tip: Creating drafts with the rib feature in Onshape
Ribs are used to add stiffness and strength to parts without adding excessive weight or increasing wall thickness -- most commonly in molded parts that require a draft angle so the part can release from the mold. See the basics of how this is done in Onshape, which features the power of cloud computing, real-time collaboration tools, and a built-in PDM system -- all for the same price as CAD.

| | Videos+: Technologies and inspiration in action | What is 3D-MID? Molded parts with integrated electronics from HARTING
3D-MID (three-dimensional mechatronic integrated devices) tech combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.
