3D printing at home

30.09.2012

Scientist Bedric Bene, in collaboration with Adobe Advanced Labs, has developed an original technology that automatically corrects the strength of parts printed on a 3D printer. This technology is very important for the widespread use of XNUMXD printing, which in the future will become available to a large number of people and open up completely new possibilities.

Already today, anyone can create on a computer with the help of a graphic editor a model of a three-dimensional object of almost any shape and, for an average of $ 300 for a small object, order a print of a part. It can be anything: people print aircraft models, decorative elements and even weapon parts.

However, often the developer does not take into account the strength characteristics of the material and the design of the object, because of which it easily breaks or loses its shape. According to Bedirch Bene, he himself has a whole museum of broken objects printed on a 3D printer. So, as an assistant professor of computer graphics at Purdue University, Bene developed a new tool that automatically calculates the strength of a structure created by an inexperienced user and simply "adds where necessary" or points out an error. A simple software algorithm analyzes an object using a grid and requires less processing power than traditional modeling tools used in high-precision work such as turbine blade modeling.

The new tool uses simple methods to solve the strength problem. By analyzing the strength of a structure and identifying weak points, it automatically strengthens the item, either by increasing the thickness of key structural elements or by adding bracing. A third option can also be used: reducing the load on structural elements by distributing the excess weight of individual elements. Bedrich Bene managed not only to help solve the problem of the strength of 3D printer products, but also to make them cheaper - weight savings in some cases reached 80%.

In the future, when XNUMXD printing will appear in almost every home, such a tool will eliminate many errors and save resources.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Mobile phone recognizes the owner 29.06.2003

The Japanese company Earth Beat, which specializes in image recognition technologies, has released GeneLock-Light, an embedded special software for authenticating users of mobile phones equipped with digital cameras.

The company's employees claim that their technology provides a high level of security and can be an attractive alternative, especially for the younger generation, to the methods of identifying a person by a four-digit PIN code, retina or fingerprint.

They believe that an important advantage of the Earth Beat solution is that it can be used in those phones with an integrated camera that are already being mass-produced at the present time.
