3DS is one of the file formats used by the Autodesk 3ds Max 3D modeling, animation and rendering software. It was the native file format of the old Autodesk 3D Studio DOS (releases 1 to 4), which was popular until its successor (3D Studio MAX 1.0) replaced it in April 1996. Having been around since 1990 (when the first version of 3D Studio DOS was launched), it has grown to become a de facto industry standard for transferring models between 3D programs, or for storing models for 3D resource catalogs (along with OBJ, which is more frequently used as a model archiving file format). While the 3DS format aims to provide an import/export format, retaining only essential geometry, texture and lighting data, the related MAX format (now superseded by the PRJ format) also contains extra information specific to Autodesk 3ds Max, to allow a scene to be completely saved/loaded.

1,2,3-Trichloropropane (TCP) is a chemical compound that was an impurity in 1,3-dichloropropene fumigants manufactured by Shell Chemical Company and Dow Chemical Company. Exposure by inhalation, skin contact, or ingestion can be harmful to health.

2-Ethoxyethanol, also known by the trademark Cellosolve or ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. 2-Ethoxyethanol can be manufactured by the reaction of ethylene oxide with ethanol. As with other glycol ethers, 2-ethoxyethanol has the useful property of being able to dissolve chemically diverse compounds. It will dissolve oils, resins, grease, waxes, nitrocellulose, and lacquers. This is an ideal property as a multi-purpose cleaner, and, therefore, 2-ethoxyethanol is used in products, such as varnish removers and degreasing solutions.

2-Methoxyethanol, or methyl cellosolve, is an organic compound with formula C 3H 8O 2 that is used mainly as a solvent. It is a clear, colorless liquid with an ether-like odor. It is in a class of solvents known as glycol ethers which are notable for their ability to dissolve a variety of different types of chemical compounds and for their miscibility with water and other solvents. It can be formed by the nucleophilic attack of methanol on protonated oxirane followed by proton transfer: C 2H 5O+ + CH 3OH → C 3H 8O 2 + H+ 2-Methoxyethanol is used as a solvent for many different purposes such as varnishes, dyes, and resins. It is also used as an additive in airplane deicing solutions. In organometallic chemistry it is commonly used for the synthesis of Vaska's complex and related compounds such as carbonylchlorohydridotris(triphenylphosphine)ruthenium (II). During these reactions the alcohol acts as a source of hydride and carbon monoxide. 2-Methoxyethanol is toxic to the bone marrow and testicles. Workers exposed to high levels are at risk for granulocytopenia, macrocytic anemia, oligospermia, and azoospermia. The methoxyethanol is converted by alcohol dehydrogenase into methoxyacetic acid which is the substance which causes the harmful effects. Both ethanol and acetate have a protecting effect. The methoxyacetate can enter the Krebs cycle where it forms methoxycitrate.

2,4-Dinitrotoluene (DNT) or dinitro is an organic compound with the formula C7H6N2O4. This pale yellow crystalline solid is well known as a precursor to trinitrotoluene (TNT) but is mainly produced as a precursor to toluene diisocyanate.

The 2016 Summer Olympics (Portuguese: Jogos Olímpicos de Verão de 2016), officially known as the Games of the XXXI Olympiad and commonly known as Rio 2016, was a major international multi-sport event celebrated in Rio de Janeiro, Brazil, from 5 to 21 August 2016. More than 11,000 athletes from 205 National Olympic Committees, including first time entrants Kosovo, South Sudan, and the Refugee Olympic Team, took part. With 306 sets of medals, the games featured 28 Olympic sports, including rugby sevens and golf, which were added to the Olympic program in 2009. These sporting events took place at 33 venues in the host city, and at five in São Paulo, Belo Horizonte, Salvador, Brasília, and Manaus. These were the first Summer Olympic Games under the International Olympic Committee (IOC) presidency of Thomas Bach. The host city Rio de Janeiro was announced at the 121st IOC Session in Copenhagen, Denmark, on 2 October 2009. Rio became the first South American city to host the Summer Olympics. These were the first games to be held in a Portuguese-speaking country, the first to be held entirely in the host country's winter, the first since 1968 to be held in Latin America, and the first since 2000 to be held in the Southern Hemisphere. The lead-up to these Games was marked by controversies, including the instability of Brazil's federal government; the country's economic crisis; health and safety concerns surrounding the Zika virus and significant pollution in the Guanabara Bay; and a doping scandal involving Russia, which affected the participation of its athletes in the Games. The United States topped the medal table for the fifth time in the past six Summer Olympics, winning the most golds (46) and most medals overall (121), as well as its 1,000th Olympic gold medal overall. Great Britain finished second and became the first country in the history of the modern Olympics to increase its tally of medals in the subsequent games after being the host nation. China finished third. Host country Brazil won seven gold medals, its most at any single Summer Olympics, finishing in thirteenth place. Bahrain, Fiji, Jordan, Kosovo, Puerto Rico, Singapore, Tajikistan, Ivory Coast and Vietnam each won their first gold medals, as did the group of Independent Olympic Athletes (from Kuwait).

3D bioprinting is the process of creating cell patterns in a confined space using 3D printing technologies, where cell function and viability are preserved within the printed construct. Generally, 3D bioprinting utilizes the layer-by-layer method to deposit materials known as Bioinks to create tissue-like structures that are later used in medical and tissue engineering fields. Bioprinting covers a broad range of materials. Currently, bioprinting can be used to print tissues and organs to help research drugs and pills. In addition, 3D bioprinting has begun to incorporate the printing of scaffolds. These scaffolds can be used to regenerate joints and ligaments. The first patent related to this technology was filed in the United States in 2003 and granted in 2006.

3D Hubs is an online 3D printing service platform. It operates a network of 6,370 3D printing services in over 150 countries, providing over 1 billion people access to a 3D printer within 10 miles (16km) of their home. The company facilitates transactions between 3D printing services (Hubs) and engineering/product designers that want to make 3D prints. Service bureaus can join the platform to offer 3D printing services while customers can locate them based on geography to get their 3D models printed nearby.

3D Manufacturing Format or 3MF is a file format developed and published by the 3MF Consortium. 3MF is an XML-based data format designed for using additive manufacturing, including information about materials, colors, and other information that cannot be represented in the STL format. As of today, CAD software related companies such as Autodesk, Dassault Systems and Netfabb are part of the 3MF Consortium. Other firms in the 3MF Consortium are Microsoft (for Operating system support), SLM and HP, whilst Shapeways are also included to give insight from a 3D Printing background. Other key players in the 3D printing and additive manufacturing business, such as Materialise, 3D Systems, Siemens PLM Software and Stratasys have recently joined the consortium.

In 3D computer graphics, 3D modeling (or three-dimensional modeling) is the process of developing a mathematical representation of any surface of an object (either inanimate or living) in three dimensions via specialized software. The product is called a 3D model. Someone who works with 3D models may be referred to as a 3D artist. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices. Models may be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling applications or modelers.
