    Students Design 3D-Printed Car for Shell

    As part of Shell’s Eco-marathon energy challenge, participants designed and created a car that could travel the farthest distance possible on one liter of gas. A team from Nanyang Technological University in Singapore designed and 3D-printed a pair of vehicles with lightweight carbon fiber material to conserve energy.

    The 3D printing technology allowed the team to produce a vehicle made up of 150 pieces. They also incorporated a honeycomb-like structure to maximize driver comfort and reach speeds of up to 37 miles per hour.

    Airshow Features 3D Printing Advancements

    Farnborough, England’s biennial airshow showcases the latest advancements in 3D technology within the aviation and aerospace industries, including Norsk Titanium’s developments with Rapid Plasma Deposition (RPD)—a form of 3D printing patented by the company. 

    By bonding layers of titanium together, which are then printed into a net shape, the RPD process cuts down on production time for a quicker entry to market. The material has been used within many aerospace products, including Airbus’ A350. The aircraft features close to 14 percent titanium; utilizing RPD saves the company just over $2 million per plane in waste and energy usage.

    Augmented Reality and Product Development

    Augmented reality (AR) isn't just for video games. Its capabilities are being incorporated into CAD and engineering for numerous industries, including medical and healthcare fields, navigation and military.

    AR allows designers and engineers to see their models in real-life settings using head-mounted displays, AR glasses and mobile or tablet devices. The technology enables users to design in the same environment their product will be used in, which helps them account for space restrictions or barriers and scale their models accurately.

    GE Uses 3D Printing for Nuclear Power Plant Replacement Parts

    The U.S. Department of Energy has appointed GE Hitachi Nuclear Energy (GEH) to lead a 3D printing project for the use of nuclear replacement parts in the hopes of developing safer, more efficient nuclear plants.

    Because many pieces for a nuclear plant cannot be produced quickly in large quantities, 3D printing is considered an ideal solution that saves time and production costs. 3D printing replacement pieces also gives these power plants added sustainability while moving away from dangerous energy sources and costly production methods.


    6 Steps to Navigate Your Way in Integrated CAM

    Autodesk recently integrated CAM into its Fusion 360 software, giving designers more flexibility when it comes to sharing and program creation. The new integration supports collaboration in real-time while also enabling designers to import files in differing formats.  

    To get the most efficiency out of Integrated CAM, these six steps, which include setup creation and toolpathing among others, help simplify workflow and design.

    Mesh-Editing Technology Incorporates Intelligent 3D Navigation

    A new advancement by Autodesk now gives users the ability to modify STL and OBJ files within the software without having to make the switch to MeshMixer. Designers can now create, modify, erase and fill meshes all within Fusion by using the tools and workflow in their dashboards. 

    These updates effectively incorporate Intelligent 3D Navigation (I3DN) to Fusion, allowing for a smoother, faster workflow for users. Many of the mesh-editing tools and commands are the first of their kind within CAD technologies, with tools including Rebuild as Solid, Remesh and more. 

    Four Underrated AutoCAD Dimensioning Tips

    The dimensioning tool in Autodesk’s AutoCAD includes many unique features. However, there are some—like Dual Dimensioning and creating Custom Arrow Styles—that may go unnoticed despite their value in everyday usage. 

    If a user wanted to differentiate between inches and centimeters, Dual Dimensioning enables them to specify the lengths using a multiplier. Both dimensions are then displayed on the user’s model throughout production, which saves time and allows for easier conversions.


    Onshape Used in Railroad Museum 3D Printing Courses

    The San Diego Model Railroad Museum is using the CAD software OnShape in its 3D printing classes, which are offered as a result of substantial interest in CAD and 3D printing technology.

    Because Onshape offers a variety of packages to accommodate different skill levels, students are able to learn at their own speed and improve their CAD abilities. The classes also open up new opportunities for the museum itself as 3D-printed railroad models gain popularity among enthusiasts.
