Merritt considering 3D printer to help build homes for evacuees

Posted by in categories: 3D printing, habitats, security

Following November’s catastrophic flooding events, roughly 600 Merritt residents still haven’t returned to their homes, but a 3D printer may speed up the process. Greg Solecki, the Merritt’s recovery manag.

“Our biggest priority is getting people back to Merritt and into homes and this 3D-printed option is looking like the most viable one right now,” Solecki said.

Scientists 3D print microscopic Star Trek spaceship that moves on its own

Posted by in categories: 3D printing, chemistry, physics

Circa 2020 o.o!

A team of physicists at a university in the Netherlands have 3D-printed a microscopic version of the USS Voyager, an Intrepid-class starship from Star Trek.

The miniature Voyager, which measures 15 micrometers (0.015 millimeters) long, is part of a project researchers at Leiden University conducted to understand how shape affects the motion and interactions of microswimmers.

Electric Jet Engine Uses 3D Printed Compressor, Skips The Turbine Altogether

Posted by in categories: 3D printing, energy, engineering, transportation

Turbojet engines are an incredible piece of 20th century engineering that except for some edge cases, have mostly been replaced by Turbofans. Still, even the most basic early designs were groundbreaking in their time. Material science was applied to make them more reliable, more powerful, and lighter. But all of those incredible advances go completely out the window when you’re [Joel] of [Integza], and you prefer to build your internal combustion engines using repurposed butane canisters and 3D printed parts as you see in the video below the break.

To understand [Integza]’s engine, a quick explanation of Turbojet engines is helpful. Just like any other internal combustion engine, air is compressed, fuel is burned, and the reaction produces work. In a turbojet, a compressor compresses air. Fuel is added in a combustor and ignited, and the expanding exhaust drives a turbine that in turn drives the compressor since both are attached to the same shaft. Exhaust whose energy isn’t spent in turning the turbine is expelled and produces thrust, which propels the engine and the vehicle it’s attached to in the opposite direction. Simple, right? Right! Until the 3D printer comes in.

Researchers establish first-of-its-kind framework to diagnose 3D-printing errors

Posted by in categories: 3D printing, media & arts, robotics/AI

Additive manufacturing, or 3D printing, can create custom parts for electromagnetic devices on-demand and at a low cost. These devices are highly sensitive, and each component requires precise fabrication. Until recently, though, the only way to diagnose printing errors was to make, measure and test a device or to use in-line simulation, both of which are computationally expensive and inefficient.

To remedy this, a research team co-led by Penn State created a first-of-its-kind methodology for diagnosing errors with machine learning in real time. The researchers describe this framework—published in Additive Manufacturing —as a critical first step toward correcting 3D-printing errors in real time. According to the researchers, this could make printing for sensitive devices much more effective in terms of time, cost and computational bandwidth.

“A lot of things can go wrong during the process for any component,” said Greg Huff, associate professor of electrical engineering at Penn State. “And in the world of electromagnetics, where dimensions are based on wavelengths rather than regular units of measure, any small defect can really contribute to large-scale system failures or degraded operations. If 3D printing a household item is like tuning a tuba—which can be done with broad adjustments—3D-printing devices functioning in the electromagnetic domain is like tuning a violin: Small adjustments really matter.”

‘First community of 3D printed, recycled plastic homes’ to be built in California

Posted by in categories: 3D printing, habitats

California-based Azure Printed Homes has announced intentions to construct 14 prefabricated 3D printed homes using recycled plastic. The homes will form part of a new housing development in Ridgecrest, California, led by Oasis Development.

The project will build on Azure’s existing production of backyard studios and ADUs, which it produces from its factory in Culver City, CA. The company claims that 3D printing their ADUs and studios from recycled plastic allows them to build the units 70% faster and with 30% fewer costs than traditional home construction methods.

Researchers make regenerative medicine breakthrough with volumetric 3D bioprinted livers

Posted by in categories: 3D printing, bioprinting, biotech/medical, life extension

A research team from Utrecht University has successfully fabricated working livers using a newly developed ultrafast volumetric 3D bioprinting method.

By means of visible light tomography, the volumetric bioprinting method enabled the successful printing of miniature stem cell units by making the cells “transparent”, which meant they retained their resolution and ability to perform biological processes.

Printed in less than 20 seconds, the liver units were able to perform key toxin elimination processes mimicking those that natural livers perform in our bodies, and could open new opportunities for regenerative medicine and personalized drug testing.

DIY Float Valve For Passive Hydroponics Leverages 3D Printing

Posted by in categories: 3D printing, habitats

[Billy] has a special interest in passive hydroponics (also known as the Kratky method), which is a way of growing plants in nutrient-rich water that does not circulate. As the plant grows and liquid level drops, only the tips of the roots remain submerged while more and more of the root surface is exposed to oxygen in a harmonious balance. However, “thirsty” plant types (tomatoes, for example) throw off this balance, and the system needs to be modified. To address this, [Billy] designed and printed a passive float valve system that takes care of topping up the reservoir only when needed, without using pumps or any other electrical equipment.

Commercial or industrial float valves are too big to use in his small tanks, which led [Billy] to test dozens of DIY designs. He used everything from plastic water bottles to pipe ends, but nothing quite measured up. With 3D printing, [Billy] was able to create a sealed, lightweight float that exactly matched the housing and tube locations.
