(Underwater Concrete 3D Printing)

Traditional underwater construction faces significant challenges, notably the “washout” problem where cement is easily dispersed by water currents. Project lead Professor Sriramya Nair highlights the team’s core breakthrough in material formulation: they have successfully developed a specialized concrete primarily composed of seafloor sediment. This mixture significantly reduces the amount of cement required and its associated transport costs, while effectively resisting erosion in the underwater environment.

This technology involves more than just material science; it is an integrated systems engineering challenge. The team brings together interdisciplinary experts in materials science, robotics, and architectural design. They have equipped robotic arms with specialized sensors to navigate the turbid underwater conditions, enabling real-time monitoring and adjustment of the printing path.

The team is currently conducting intensive testing in a laboratory water tank in preparation for DARPA’s final underwater “bake-off” competition next March, where participating teams must demonstrate the on-site printing of an underwater arch structure. If successful, this research could fundamentally transform maritime construction practices, realizing the vision of intelligent building with “minimal disturbance to the ocean.”

Roger Luo said:This research transforms marine construction by turning local sediment into structural material, drastically cutting cost and environmental impact. The real challenge lies in scaling the system for dynamic ocean environments and ensuring long-term durability against currents and biofouling.

(3d printer)

Microparticles produced by 3D printing technology are extensively made use of in areas such as medicine and injection delivery, microelectronics, microfluidics, and complex production. However, mass customization of such particles is incredibly challenging.

r2rCLIP is based upon the continual liquid user interface production (CLIP) publishing technology created by Stanford College’s DiSimone Research laboratory in 2015. CLIP utilizes ultraviolet light to strengthen the resin swiftly into the desired shape.

The leader of the most up to date research, Jason Kronenfeld of the Disimone Laboratory, explained that they first fed an item of movie right into a CLIP printer. At the printer, hundreds of forms are all at once printed onto the film; the system then proceeds to tidy, cure, and eliminate the shapes, all of which can be personalized to the desired shape and product; ultimately, the film is rolled up. The whole procedure, hence the name roll-to-roll CLIP, enables mass production of distinctively shaped fragments smaller sized than the size of a human hair.

(metal powder 3d printing)

Researchers stated that prior to the arrival of r2rCLIP, if you wished to publish a batch of big particles, you needed to refine it by hand, and the procedure advanced gradually. Currently, r2rCLIP can generate as much as 1 million fragments per day at extraordinary speeds. With brand-new innovations, they can now swiftly create microparticles with even more complicated forms utilizing a range of materials, such as porcelains and hydrogels, to produce tough and soft particles. The difficult particles can be made use of in microelectronics manufacturing, while the soft fragments can be utilized in drug shipment within the body.

The research group explained that existing 3D printing technology needs to discover an equilibrium in between resolution and rate. Some 3D printing modern technologies can create smaller nanoscale particles yet at a slower speed; some 3D printing innovations can mass-produce big items such as footwear, family items, device components, football helmets, dentures, and listening device, however they can not print Fine microparticles. The new method discovers a balance in between producing speed and penalty range.
