Ceramic 3D Printing Capabilities Expand with New Admatec Debinding and Sintering Equipment

Posted by in categories: 3D printing, materials

Admatec has steadily been increasing its 3D printing capabilities, taking its slurry-based digital light processing (DLP) process further. First it expanded from resins loaded with ceramic particles to those loaded with metal particles. It then increased the build volume of its Admaflex300 3D printer. Now, the company has introduced a new integrated debinding and sintering furnace with a larger work volume.

The majority of ceramic 3D printing processes rely on the use of a photopolymer slurry loaded with ceramic particles. Once printed, these green parts first go through a debinding process, in which the photopolymer material is removed, followed by sintering, causing the part to become fully dense.

Light-based 3D printing technique prints full objects in just seconds

Posted by in categories: 3D printing, innovation

Circa 2020


Researchers have created a new 3D printing technique that could replace traditional 3D printers that take far to long to create desired objects.

The problem with traditional 3D printers is that they work in horizontal layers. This process is the bane of 3D printing, as it means that, depending on the size of the object, it will take time to construct. What if the printer could build the entire model all at once, instead of layer-by-layer? Researchers from Switzerland’s Ecole polytechnique federale de Lausanne (EPFL) have done just that with their new invention.

Recycled glass waste used as sand replacement in 3D printing

Posted by in categories: 3D printing, climatology, sustainability

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction.

Glass is one material that can be 100% recycled with no reduction in quality, yet it is one of the least recycled waste types. Glass is made up of silicon dioxide, or silica, which is a major component of sand, and therefore it offers significant untapped potential to be recycled into other products.

At the same time, due to growing populations, urbanization and , the world is facing a shortage of sand, with calling it one of the greatest sustainability challenges of the 21st century.

Can 3D-printing homes make them affordable?

Posted by in categories: 3D printing, computing

BLACKSBURG, Va. (WFXR) – As housing prices across the country continue to skyrocket, an Iowa-based company, Alquist 3D, is looking to combat the crisis by 3D-printing homes.

Alquist, one of a few U.S. companies that 3D-prints houses, is looking to build 200 of these homes in Virginia starting this summer.

The process is somewhat simple. First, a person designs what they want the frame of the house to look like by using a computer program. Then, a file is transmitted to a machine, which tells it what to do and how to move.

Scientists develop rapid new method of 3D printing glass into parts with “the thickness of hair”

Posted by in categories: 3D printing, materials

Researchers at the University of Freiburg have worked with colleagues at the University of California, Berkeley to come up with a novel means of rapidly 3D printing complex glass parts at a microscopic scale.

Known as ‘Microscale Computed Axial Lithography’ (Micro-CAL), this approach involves exposing resin to 2D light images of a desired shape from multiple angles, which when they overlap, trigger polymerization. When used to print the Glassomer material previously honed at Freiburg, the team say their layer-free process has the potential to unlock devices with new microfluidic or micro-optical functionality.

“For the first time, we were able to print glass with structures in the range of 50 micrometers in just a few minutes, which corresponds roughly to the thickness of a hair,” explains the University of Freiburg’s Dr. Frederik Kotz-Helmer. The ability to manufacture such components at high speed and with great geometric freedom will enable new functions and more cost-effective products in the future.”

Taller Wind Turbines To Get TLC From 3D Printing

Posted by in categories: 3D printing, energy, finance, sustainability

GE is ready to rock the world of onshore wind turbines with 3D printing for a new concrete base.


Vast swaths of the US have yet to be tapped for wind energy, partly on account of politics and partly because wind speeds in those areas are less than optimal. Only the voting public can take care of the political end. Meanwhile, engineers and innovators are hammering away at the wind speed issue, which can be solved by building taller wind turbine towers. That’s not as easy as it sounds, but GE Renewable Energy is banking on 3D printing to overcome the obstacles.

Why Not Taller Wind Turbines?

Laser-based 3D printer can produce complex objects in any order

Posted by in categories: 3D printing, energy

A 3D printer that uses lasers to build up an object in any order, rather than layer by layer, could produce more advanced designs than is currently possible.

Existing 3D printers work by depositing layers of a plastic filament from a nozzle or by curing layers of resin with UV light. In both cases objects are built up one layer at a time, meaning that overhanging parts of a structure – the outstretched arms of a model human, say – must be propped up by temporary supports until printing is complete. These supports must then be carefully removed manually.

To get around this, Dan Congreve at Stanford University in California and his colleagues created a 3D-printing system that involves focusing a red laser at a particular point in a pool of resin. The resin is impregnated with particles 80 nanometres wide that convert red light into blue once the light hits a certain energy threshold, which only occurs at the point where the red laser is precisely focused.

3D Printed IC to Reshape the Semiconductor Industry

Posted by in categories: 3D printing, computing

3D printed ICs overcome semiconductor shortage and reinforce supply chains, leading to cheaper production costs, faster prototyping, and faster time to market.


As the size of microchip packages shrinks, semiconductor manufacturers are under pressure to improve lithography capabilities. For more than two decades, researchers have been working on 3D printed integrated circuits. Earlier attempts at 3D printing electronics used the proper technique but failed to reach the required levels of conductivity for a PCB, leaving complicated electrical circuits unusable. Over time though, these printing tools have gradually improved feature size resolution, yield, and variability in production.

● A broad variety of materials may be used to produce an assortment of printed electronics, including conductors, semiconductors, dielectrics, resistors, and other components. ● As has been the case in other areas, additive manufacturing is expected to result in more innovative products, lower costs, and faster production runs.
