Opportunities and challenges of 3D printing in education

The future of 3D printing and manufacturing

Posted on Updated on

BigRep 3D Printer Reviews.
We always skeptical about the future of 3D printing and manufacturing. Nowadays technology is with the combination of Artificial Intelligence, Nano, Virtual Reality and 3D Printers.

3D printers are speeding up the manufacturing process. We are using 3D, 4D, and 5D printing. We already know parts can be printed, retrieved and installed by a robot.

3D-printed concrete structure

Posted on Updated on

According to Asst Prof Pham from NTU’s School of Mechanical and Aerospace Engineering, “We envisioned a team of robots which can be transported to a work site, print large pieces of concrete structures and then move on to the next project once the parts have been printed.
This research builds on the knowledge we have acquired from developing a robot to autonomously assemble. But this latest project is more complex in terms of planning, execution, and on a much larger scale.”

Hierarchical 3-D Printing of Nano porous Gold

Posted on Updated on

According to Chris Spadaccini the director of LLNL’s Center for Engineered Materials and Manufacturing, “There are a whole lot of scientific and engineering challenges left, but it could have the significant impact, scaling up should be easier with small-scale reactors because you can parallelize. You could have an array of small 3-D reactors together instead of one large vessel enabling you to control the chemical reaction process more effectively. The Monolithic nanoporous metals, derived from dealloying, have a unique bicontinuous solid/void structure that provides both large surface area and high electrical conductivity, making them ideal candidates for various energy applications”.

3D printed silicone models

Posted on Updated on

3D printed silicone models. According to WACKER and engineer Hannah Riedle from the University of Erlangen, “the Munich-based chemical group, is currently expanding its ACEO 3D printing services for silicone rubber and announced the opening of a US-based printing lab later this year. The facility, which will be located at WACKER’s R&D center for silicone’s in Ann Arbor (MI), is the company’s first regional 3D printing lab outside of Germany.
We can print 3D silicone models based on medical image data that we obtain from magnetic resonance imaging or computed tomography”.
