Reinventing Metal 3D printing with new Direct Writing process

Metal 3D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations. Parts produced using selective laser melting (SLM) and other powder-based metal techniques often end up with gaps or defects caused by a variety of factors. To … Continue reading “Reinventing Metal 3D printing with new Direct Writing process”

New 3-D-printed device mimics the Goldbug Beetle, which changes color when prodded.

New 3-D-printed device mimics the goldbug beetle, which changes color when prodded. In this age of smartphones and tablet computers, touch-sensitive surfaces are everywhere. They’re also brittle, as people with cracked phone screens everywhere can attest. Covering a robot — or an airplane or a bridge — with sensors will require a technology that is … Continue reading “New 3-D-printed device mimics the Goldbug Beetle, which changes color when prodded.”

Achieving the full potential of 3D and 4D printing through computational design

3D printers are becoming more and more capable – for example, we can now print in 40 materials simultaneously, or print structures that will change in response to aspects of their environment, such as temperature. Kristina Shea, Professor for Engineering Design and Computing at ETH Zürich, argues that designers need computational aids to help them … Continue reading “Achieving the full potential of 3D and 4D printing through computational design”

Vader Systems creates Liquid Metal 3-D Printer for manufacturing

A father and son team in the START-UP NY program have invented a liquid metal printing machine that could represent a significant transformation in manufacturing. Their company named “Vader System” has created a machine that prints three-dimensional objects using liquid metal. Engineering faculty and students of University at Buffalo work closely with this company.
