Slideshow: More Seismic Shifts in 3D Printing Materials
Engineering Materials 3/27/2014 9 comments This is the fourth blog in an occasional series on 3D printing and additive manufacturing. This time, we'll tell you about architects 3D printing with ice and marble, some firsts in 3D printing titanium, and a university R&D team with a faster way to print multimaterial objects.
Slideshow: Drop-in Jet Biofuels Becoming a Reality
Engineering Materials 3/25/2014 16 comments Drop-in jet biofuels have started becoming a reality during the last year. Along with major deals between airlines, engine makers, and fuel producers, one main source may turn out to be renewable diesel already used in ground vehicles, which could make prices competitive with fossil jet fuels.
Obama Announces 2 New Innovation Hubs
Blog 3/24/2014 4 comments In an effort to boost US manufacturing, President Obama recently announced the opening of two new manufacturing innovation hubs -- in Chicago and Detroit. The hubs will serve as institutions to increase manufacturing technology in the US and will create local jobs for middle-class workers.
Video: Is the MX3D-Metal the Future of 3D Printing?
Blog 3/20/2014 11 comments Unlike many of the 3D printers available, the MX3D printers can work around a part rather than building it straight up. Using such techniques, the printer can print objects on surfaces with angles and slopes or even directly onto walls. In addition, it can print curves and shapes with much more precision and accuracy.
3D-Printed Smart Membrane Detects Heart Problems
Blog 3/19/2014 24 comments A research team in the lab of Igor Efimov at Washington University in St. Louis has developed a prototype for a stretchy, custom-fitted, implantable membrane that can give doctors feedback about irregularities occurring inside someone's heart.
Shrimp Shells Make Compostable, Moldable Bioplastic
Engineering Materials 3/18/2014 19 comments Wyss Institute researchers at Harvard have created a low-cost, biodegradable plastic made from shrimp shells that can be used to mass-produce 3D compostable consumer goods, using injection molding or casting processes.
3D-Printed Wood – Really!
Engineering Materials 3/17/2014 42 comments Does it sound like magic? It's not. You can 3D-print with wood filaments right now, using a choice of colors and filament widths. Objects made from these materials range from things resembling plastic or lumber to stunningly beautiful art pieces that look just like the real thing.
Slideshow: 3D-Printed Carbon Composite Yacht Model
Engineering Materials 3/13/2014 7 comments CRP Technology has 3D-printed a 1:14 scale model of a yacht in carbon fiber composites to demonstrate the possibilities and give a boost to boat design. The material and process are also used for under-hood motorsport applications and in aerospace.
Understanding the Fluid Dynamics of Boundary Layers
Guest Blogs 3/6/2014 7 comments A customer who was thermal printing strip steel had a problem: When the strip's speed increased, the thermo printer would catch fire. When he set a flame to a piece of the strip, he couldn't get it to burn. What was the problem?
Carbon & Fiberglass Composite Compound Is Cheaper
Engineering Materials 3/5/2014 9 comments A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Machines Can’t Do What Engineers Do So Well
Guest Blogs 3/5/2014 23 comments Engineers are well positioned to be the leaders for innovation in this new age of machines. Human-centered design enables us to manage the vast amounts of information and the power of technology in solving the world’s problems.
My Opinion on Walking the STEM Walk
STEM Connection 3/4/2014 19 comments We are giving the First folks (and any associated parties) a mechanism to get their word out. If you're involved with First or have anything to say about the organization, let us know.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
