Design of bimetallic 3D-printed electrocatalysts via galvanic replacement to enhance energy conversion systems

“3D-printing (also known as additive manufacturing) has recently emerged as an appealing technology to fight against the mainstream use of carbon-based fossil fuels by the large-scale, decentralized, and sustainable manufacturing of 3D-printed electrodes for energy conversion devices. Although promising strides have been made in this area, the tunability and implementation of cost-effective metal-based 3D-printed electrodes is a challenge. Herein, a straightforward […]

Physical-mechanical behaviors of stainless steel plate-lattice built by material extrusion additive manufacturing

“Additive manufacturing (AM) technology has been widely adopted for the fabrication of metal lattices due to its freeform design capability over traditional manufacturing methods. However, the prevalent laser-based AM technologies possess high energy and investment consumption, and relatively low manufacturing speed, hampering their widespread adoption in building metal lattice components. In this study, an integrated approach of material extrusion AM,

3D Printed Titanium Breakthrough!

3D Printed Titanium Breakthrough! A newly published paper by David Alexander of the University of Texas at El Paso, Doctoral Program in Aerospace and Mechanical Engineering details a method for using Filamet™ to create Fuel Cell components using low-cost commercial materials and equipment. For the many people that are working with our Titanium Products, this

Why are Aluminum and Titanium Filamet™ “Untested”?

Why is Aluminum more difficult to sinter than the other materials we work with at The Virtual Foundry? It’s actually a pretty interesting story, let’s talk through it. In a word, Oxides. One of the things that makes Aluminum such a useful material is that it doesn’t corrode. But, here’s the catch, it does corrode.

Liquid Phase Sintering

Since the beginning of The Virtual Foundry, I’ve been experimenting with nearly every variation, adaptation and enhancement for the most common methods of sintering for 3D Metal prints. One that we have not yet perfected but shows tremendous promise is Liquid Phase Sintering. This technique provides a method of producing a part of very low

Make48 at Fab-Lab Stoughton

I just got back from a remarkable spectacle, Make48 at Fab-Lab Stoughton. -Sponsord by Trek (and Trek went all in!) Make48 at Fab-Lab Stoughton – Here’s the description from the Make48 website: Make48 is a nationwide, invention-competition docuseries that gives teams a challenge at the start of a two-day event. With just 48 hours, teams
