Metal-breathing bacteria could transform electronics, biosensors, and more

When the Shewanella oneidensis bacterium “breathes” in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices. The ability of this bacterium to produce molybdenum disulfide — a material that is able to transfer electrons

Water molecules are gold for nanocatalysis

Nanocatalysts made of gold nanoparticles dispersed on metal oxides are very promising for the industrial, selective oxidation of compounds, including alcohols, into valuable chemicals. They show high catalytic activity, particularly in aqueous solution. A team of researchers from Ruhr-Universität Bochum (RUB) has been able to explain why: Water molecules play an active role in facilitating

Honeywell and SLM Solutions qualify parameters for 3D printing thicker aluminum aerospace parts 

German metal 3D printer manufacturer SLM Solutions has worked with the aerospace division of multinational manufacturing conglomerate Honeywell, to produce a parameter set for 3D printing aluminum F357.  Developed as part of the companies’ ongoing partnership, the material reportedly provides  3D printed parts with considerably improved properties compared to those created through die-casting methods. In

Optomec launches ROI assessment tool calculating the cost savings of using 3D printing for MRO

Optomec, the New Mexico-based developers of Laser Engineered Net Shaping (LENS) and Aerosol Jet Printing (AJP) metal 3D printers, has launched a new Return On Investment (ROI) assessment tool.  Built on Optomec’s own remanufacturing experience, the cost calculator is reportedly able to assess the profitability of automated laser cladding equipment for gas turbine Maintenance and

Atomic ‘Swiss army knife’ precisely measures materials for quantum computers

It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields. Scientists at the National Institute of Standards and Technology (NIST) have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously. Together,

Australian Army successfully conducts field test of SPEE3D metal 3D printer

The Australian Army has carried out a field test of metal 3D printer manufacturer SPEE3D’s WarpSPEE3D additive manufacturing (AM) systems.  Taking place in various locations across the Australian Northern Territories, the three day trial demonstrated the efficacy of metal 3D printed parts during field training. Throughout testing, SPEE3D’s 3D printers proved capable of being deployed

Amaero’s high-performance aluminum alloy enters final stage of patent approval

Metal AM specialist Amaero has announced that its high-performance 3D printing aluminum alloy, Amaero HOT Al, has entered the national phase (fourth and final stage) of international patent approval. The patent was submitted as part of the Patent Co-operation Treaty, whereby more than 150 participating countries recognise an invention and protect it through one single

VELO3D raises additional $12M in funding, bringing total to $150M

Californian metal 3D printer manufacturer VELO3D has announced that it has raised $12M in fundraising with the addition of new strategic investors. Initially revealed in a LinkedIn post by VELO3D Founder and CEO Benny Buller, the news follows the company’s announcement in April that it had raised $28M in a Series D funding round. Total

3DEO passes 150,000 part milestone on quest to achieve high volume manufacturing 

Los Angeles-based metal 3D printed part provider 3DEO, has officially shipped 150,000 production parts for end-use applications.  The milestone is an important one for the on-demand additive manufacturer, which has had to compete in high-volume metal manufacturing markets against conventional manufacturing techniques such as CNC machining and metal injection molding. “150 thousand parts is a

Protolabs launches cobalt chrome superalloy for its metal laser sintering service

Digital prototyping specialist Protolabs has launched a new 3D printing material for its metal laser sintering process – cobalt chrome superalloy. The UK-based company believes the heat, wear, and corrosion resistant material will disrupt a number of industries including oil and gas where customized cobalt chrome parts were not previously possible.
