3D Printing of Aluminum F357 for Thin-Walled Heat-Transfer Applications
Velo3D announced the release of a process for additive manufacturing (AM) of parts using aluminum F357 on the company’s Sapphire metal 3D printing system. The foundry-grade aluminum alloy, suitable for the laser powder-bed fusion (LPBF) process, enables 3D printing of parts that traditionally had been manufactured via casting. Aluminum F357 can be anodized and shares characteristics with A356, a widely used casting alloy.

3Diligent Updates Procurement Service with On-Demand Quoting and Search Tools, and New Shop Software
3Diligent has updated its procurement service with new software—called ProdEx—and introduced new manufacturing shop-management software called 3Diligent Shopsight. The two services work together to enhance the firm’s Industry 4.0 offering.

Using ProdEx, engineers and buyers of parts and assemblies can one-stop shop for express manufacturing across thousands of material and technology combinations. ProdEx, powered by users of Shopsight, provides shop managers with tools to manage and enhance their operations, sourcing custom parts on-demand through a secure web portal.

Software, 3D Printing Deliver Suspension Lightweighting for Eco-Friendly Vehicle
XponentialWorks is teaming with Arcimoto, Inc. to design and fabricate lightweighted components for Arcimoto’s Fun Utility Vehicle (FUV), with the goal of reducing cost, improving performance and efficiency, and making the vehicle more environmentally friendly.

If successful, the new parts, designed via XponentialWorks’ Paramatters CogniCAD computer-generated design and reverse-engineering software, may take the place of heavier, regularly manufactured parts. This will allow Arcimoto’s electric vehicles to drive farther on a single charge, improve acceleration and deliver better handling―all while reducing part-production costs.

The project team used Paramatters software to redesign and fabricate new parts with geometries that mimic natural structure, according to XponentialWorks officials, and promises significant savings in part weight. Here’s a video demonstration of the software.

Lightweighted parts include: a rear swing arm with weight reduced by 34 percent; knuckle, lightweighted by as much as 36 percent; upper control arm, with weight reduced by as much as 52 percent; and brake pedal, lightweighted by as much as 49 percent.

Diffusion Bonding Builds Complex Metal Parts with Internal Passageways
Machine shops can leverage the capabilities of 3D metal printing to create complex parts by using diffusion bonding to join thin sheets of similar or dissimilar metal alloys. Applications for the process, called laminated-object manufacturing, include conformal cooling and heat exchangers.
