Throwing off sparks — My best friend visited for the weekend from across the country and we tried our hands at different types of solar printing - first with a turmeric solution and second with solarfast. Solarfast continues to be my enemy (haven’t had a single print turn out so far) but at least now I have some cool textured and toned paper to work on.

Anyway here’s my hand.

A solar print (red) from a digital negative (black and white) only took 7 months to make on the dashboard of my car.

None of my photos of the real eclipse turned out really well so I’ve decided to fake some. Think anyone will notice?

Y'all wonderful people at Anthrocon cleared me out of several print editions! Most I have re-ordered, but there's some that I am RETIRING! So, last chance to get a signed print of these images! Head to my site to snag one.

Swiss researchers develop robotic additive manufacturing method that uses earth-based materials—and not cement

Researchers at ETH Zurich, a university in Switzerland, have developed a new robotic additive manufacturing method to help make the construction industry more sustainable. Unlike concrete 3D printing, the process does not require cement.

According to a press statement from ETH Zurich, the robotic printing process, called impact printing, uses cheap, abundant, and low-carbon earth-based materials such as clay or excavated earth. Currently, the robotic additive manufacturing method uses a mix of excavated materials, silt, and clay. Most of the custom material is common waste product sourced locally from Eberhard Unternehmungen, a Swiss construction company. In the future, the process could use other materials.

With ETH Zurich’s method, a robot deposits material from above, gradually building a wall. On impact, the pieces of material bond together, with minimal additives. Whereas concrete 3D printing creates layers, ETH Zurich’s method extrudes and drops the material one bit at a time at velocities of up to 10 meters per second. The fast speed allows the material to bond quickly.

ETH Zurich’s process can build full-scale, freeform structures, including one- or two-story walls and columns. The printing tool has been used to build structures as tall as almost 10 feet. The process results in walls with a bumpy texture, but robotic surface finishing methods can achieve a smoother finish.

The custom printing tool can be integrated with multiple robotic platforms. As a result, the tool can build walls in both offsite facilities and onsite construction projects. At ETH Zurich’s Robotic Fabrication Laboratory, the tool has been integrated with a high-payload gantry system. The hardware can be mounted on an autonomous legged excavator to build walls on sites with variable terrain.

ETH Zurich says it aims to increase the cost competitiveness of sustainable building materials through efficient and automated production.

Sun printing is great fun, no two are the same. I use these backgrounds in my sun print embroidery kits, and thought you might like to see the process. You can either have a go yourself or buy one of my kits and make yourself some art. It is easy, and suitable for beginners.

Faced with the world's impending freshwater scarcity, a team of researchers in Singapore turned to solar steam generators (SSGs), which are emerging as a promising device for seawater desalination. Desalination can be a costly, energy-intensive solution to water scarcity. This renewable-powered approach mimics the natural water cycle by using the sun's energy to evaporate and isolate water. However, the technology is limited by the need to fabricate complex topologies to increase the surface area necessary to achieve high water evaporation efficiency. To overcome this barrier, the team sought design inspiration from trees and harnessed the potential of 3D printing. In Applied Physics Reviews, the team presents a state-of-the-art technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion (MJF).
