WASHINGTON — Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing ...

The construction process works quite differently from the typical building-grade 3D printing. There, the materials on their own are too weak to support a structure. Additives like cement are ...

It’s not a new technology, but as 3D printing ... A medical-grade printer — that uses a combination of materials and colors — creates even higher resolution structures when more detail ...

By harnessing abundant earth materials and advanced robotics, this method is more sustainable than traditional construction methods and even 3D printing ... These structures can support ...

Poor orientation can lead to weak spots, rough surfaces, warping, or excessive support structures. A well-chosen orientation ... 2 Upward-facing surfaces generally produce the best finish in 3D ...
