You’ll Soon Be Able to Book a Room at the World’s First 3D-Printed Hotel
El Cosmico, a hotel in Texas, will gain 43 new rooms and 18 houses, which will be printed using Icon's giant gantry-style Vulcan printer.
The first 3D-printed house in the US was unveiled just over six years ago. Since then, homes have been printed all over the country and the world, from Virginia to California and Mexico to Kenya. If you’re intrigued by the concept but not sure whether you’re ready to jump on the bandwagon, you’ll soon be able to take a 3D-printed dwelling for a test run—by staying in the world’s first 3D-printed hotel.
The hotel is under construction in the city of Marfa, in the far west of Texas. It’s an expansion of an existing hotel called El Cosmico, which until now has really been more of a campground, offering accommodations in trailers, yurts, and tents. According to the property’s website, “the vision has been to create a living laboratory for artistic, cultural, and community experimentation.” The project is a collaboration between Austin, Texas-based 3D printing construction company Icon, architecture firm Bjarke Ingels Group, and El Cosmico’s owner, Liz Lambert.
El Cosmico will gain 43 new rooms and 18 houses, which will be printed using Icon’s gantry-style Vulcan printer. Vulcan is 46.5 feet (14.2 meters) wide by 15.5 feet (4.7 meters) tall, and it weighs 4.75 tons. It builds homes by pouring a proprietary concrete mixture called Lavacrete into a pattern dictated by software, squeezing out one layer at a time as it moves around on an axis set on a track. Its software, BuildOS, can be operated from a tablet or smartphone.
Article
The Vulcan 3D Printer is a highly advanced additive manufacturing device that was developed by NASA's Langley Research Center and the US Air Force Research Laboratory (AFRL) in the early 2000s. The device was designed to print objects in space, where traditional 3D printing processes are often limited by the lack of gravity, temperature control, and access to raw materials.
Design and Architecture
The Vulcan 3D Printer is a large, compact device that is approximately 6 feet tall and 4 feet wide. It is designed to be highly modular, with interchangeable print heads, extruders, and other components. The device uses a combination of robotic and mechanical systems to move the print head and extruder, allowing for high-speed printing and precise control over the printing process.
Printing Process
The Vulcan 3D Printer uses a unique extrusion-based process to print objects. The device uses a high-temperature, high-pressure gas mixture to melt and extrude metal or ceramic powders, which are then deposited onto a substrate to form a solid object. The printing process is controlled by a sophisticated computer system that adjusts the temperature, pressure, and flow rate of the gas mixture in real-time to achieve precise control over the printing process.
Materials
The Vulcan 3D Printer is capable of printing a wide range of materials, including metals, ceramics, and polymers. The device uses a combination of powder feed systems and liquid metal systems to deposit material onto the substrate. The materials used in the printing process can be tailored to specific applications, such as printing high-temperature materials for aerospace applications or printing biocompatible materials for medical applications.
Temperature and Pressure
The Vulcan 3D Printer is capable of operating at extremely high temperatures, ranging from 500°C to 1000°C. The device also uses high-pressure gas mixtures to print materials, which allows for precise control over the printing process and the ability to print complex geometries.
Speed and Accuracy
The Vulcan 3D Printer is designed to print objects at extremely high speeds, with some reports suggesting that it can print objects at rates of up to 100 times faster than traditional 3D printing devices. The device also uses advanced sensing and control systems to achieve precise control over the printing process, allowing for accurate printing of complex geometries and small features.
Testing and Applications
The Vulcan 3D Printer has undergone significant testing and development since its inception. In 2011, NASA announced that the device had successfully printed a functional engine component in space, demonstrating its potential for use in space exploration. The device has also been used to print a variety of other objects, including satellite components, rocket nozzles, and even a functional engine for a small satellite.
Comparison to Other 3D Printing Technologies
The Vulcan 3D Printer is one of the most advanced 3D printing technologies in the world, and it is often compared to other technologies, such as FDM (Fused Deposition Modeling) and SLS (Selective Laser Sintering). While these technologies are widely used in industry and academia, the Vulcan 3D Printer offers several advantages, including its ability to print at extremely high speeds, its ability to print complex geometries, and its ability to operate in extreme environments.
Challenges and Limitations
Despite its advanced capabilities, the Vulcan 3D Printer is not without its challenges and limitations. One of the main challenges is the high cost of the device, which is estimated to be in the millions of dollars. Additionally, the device requires highly trained personnel to operate, and it requires a sophisticated control system to achieve precise control over the printing process.
Overall, the Vulcan 3D Printer is a highly advanced additive manufacturing device that is capable of printing objects in space and other extreme environments. Its unique design and printing process make it an ideal technology for a variety of applications, including space exploration, aerospace, and medical research.
