17,000% Cost Reduction with Open Source 3D Printing: Michigan Tech Study Showcases Parametric 3D Printed Slot Die System
We often cover the work of prolific Dr. Joshua Pearce, an Associate Professor of Materials Science & Engineering and Electrical & Computer Engineering at Michigan Technological University (Michigan Tech); he also runs the university’s Open Sustainability Technology (MOST) Research Group.
Dr. Pearce, a major proponent for sustainability and open source technology, has previously taught an undergraduate engineering course on how to build open source 3D printers, and four of his former students, in an effort to promote environmental sustainability in 3D printing, launched a business to manufacture and sell recycled and biodegradable filaments.

Open Source 3D printing cuts cost from $4,000 to only $0.25 says new study
Slot die coating is a means of adding a thin, uniform film of material to a substrate. It is a widely used method for the manufacturing of electronic devices – including flat screen televisions, printed electronics, lithium-ion batteries and sensors.
Up until recently, slot die components were only machined from stainless steel, restricting development and making the process expensive. Now slot dies for in-lab experimental use can be made on a 3D printer at a fraction of the cost.

Dutch firm unveils world's first 3-D-printed propeller
Three-dimensional (3-D) printing technology has caught the logistics world's attention for its potential to save on warehouse and shipping costs by producing items on demand at any location. In the past two years, for example, UPS Inc. announced plans to partner with software developer SAP SE to build a nationwide network of 3-D printers for use by its customers, and General Electric Co. spent nearly $600 million to buy a three-quarters stake in the German 3-D printing firm Concept Laser GmbH.
Recently, transportation companies have begun turning to the same technology for another application, creating the actual hardware used in vehicles that move the freight. For instance, in late 2016, global aircraft maker Airbus S.A.S. contracted with manufacturing firm Arconic Inc. to supply 3-D printed metal parts for its commercial aircraft.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
