Building Model
An architectural model is a type of scale model made to study aspects of an architectural design or to communicate design intent. They can be made from a variety of materials such as paper, plaster, plastic, resin, wood, glass and metal. They can be constructed using traditional handcraft techniques and tools, or newer technologies such as Stereolithography, Fused Deposition Modelling and Selective Laser Sintering. History Architectural models have been in use dating back to pre-history. The older models were found in Malta, such as at Tarxien Temples, and now they are at the archaeology museum in Valletta. Purpose Architectural models are used by architects for a range of purposes: * Ad hoc models, or sketch models, are sometimes made to study the interaction of volumes, different viewpoints, or concepts during the design process. They may also be useful in explaining a complicated or unusual design to builders, or as a focus for discussion between designers and consulta ...

Paper Model
Paper models, also called card models or papercraft, are models constructed mainly from sheets of heavy paper, paperboard, card stock, or foam. Details This may be considered a broad category that contains origami and card modeling. Origami is the process of making a paper model by folding a single piece of paper without using glue or cutting while the variation kirigami does. Card modeling is making scale models from sheets of cardstock on which the parts were printed, usually in full color. These pieces would be cut out, folded, scored, and glued together. Papercraft is the art of combining these model types to build complex creations such as wearable suits of armor, life-size characters, and accurate weapon models. Sometimes the model pieces can be punched out. More frequently the printed parts must be cut out. Edges may be scored to aid folding. The parts are usually glued together with polyvinyl acetate glue ("white glue", "PVA"). In this kind of modeling, the sectio ...

Resin Casting
Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. It can be done by amateur hobbyists with little initial investment, and is used in the production of collectible toys, models and figures, as well as small-scale jewellery production. The synthetic resin for such processes is a monomer for making a plastic thermosetting polymer. During the setting process, the liquid monomer polymerizes into the polymer, thereby hardening into a solid. Single-monomer resins may be used in the process, which form homopolymers (polymers containing only one type of polymer). In such uses, the "curing agent" mixed with the resin contains what is loosely referred to as a "catalyst," but which is more technically an initial source of free radicals (such as MEKP) to act as an initiator in a free-radical chemical chain reaction polymerization.

Plastic Model
:''In art and architecture, plastic model may also be any three-dimensional physical model, regardless of material.'' :''In mechanical engineering, a plastic model is a mathematical model of a material which incorporates plasticity.'' image:South-Goodwin.jpg, 300px, A 4-year-old boy starts painting an assembled plastic model of the South Goodwin Lightship A plastic model is a plastic scale model manufactured as a wikt:kit, kit, primarily assembled by hobbyists, and intended for static display. A plastic model kit depicts various subjects, with a majority depicting military and civilian vehicles. A kit varies in difficulty, ranging from a "snap-together" model that assembles straight from the box, to a kit that requires special tools, paints, and cements. Subjects The most popular subjects of plastic models by far are vehicles such as aircraft, ships, automobiles, and armored vehicles such as tanks. The majority of models depict military vehicles, due to the wider variety of form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Metal
The white metals are a series of often decorative bright metal alloys used as a base for plated silverware, ornaments or novelties, as well as any of several lead-based or tin-based alloys used for things like bearings, jewellery, miniature figures, fusible plugs, some medals and metal type. The term is also used in the antiques trade for an item suspected of being silver, but not hallmarked. A white metal alloy may include antimony, tin, lead, cadmium, bismuth, and zinc (some of which are quite toxic). Not all of these metals are found in all white metal alloys. Metals are mixed to achieve a desired goal or need. As an example, a base metal for jewellery needs to be castable, polishable, have good flow characteristics, have the ability to cast fine detail without an excessive amount of porosity and cast at between . Silver In compliance with British law, the British fine art trade uses the term "white metal" in auction catalogues to describe foreign silver items which d ...

Brass Model
Brass models, made of brass or similar alloys, are scale models typically of railroad equipment, bridges and occasionally, of buildings. Although die-cast or plastic models have made considerable advances in late 1990s and continue to improve, brass models offer finer details. Brass models, considered to be collector's pieces and museum quality finish, are often used for display purposes rather than model railroad operations. However, these can be made fully operational and many railroaders do use them on their model railroads. They are generally considerably more expensive than other types of models due to limited production quantities and the "handmade" nature of the product itself. History In the late 1950s, Japan was known for producing low cost toys and products for export. The first brass model train were born during the occupation of Japan by Allied forces. Members of allied forces saw some of the models built by various craftsman and procured photos of American steam loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling Stock
The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, freight and passenger cars (or coaches), and non-revenue cars. Passenger vehicles can be un-powered, or self-propelled, single or multiple units. A connected series of railway vehicles is a train (this term applied to a locomotive is a common misnomer). In North America, Australia and other countries, the term consist ( ) is used to refer to the rolling stock in a train. In the United States, the term ''rolling stock'' has been expanded from the older broadly defined "trains" to include wheeled vehicles used by businesses on roadways. The word ''stock'' in the term is used in a sense of inventory. Rolling stock is considered to be a liquid asset, or close to it, since the value of the vehicle can be readily estimated and then shipped to the buyer without much cost or delay. The term contrasts with fixed stock (infrastru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Command Control
Digital Command Control (DCC) is a standard for a system to operate model railways digitally. When equipped with Digital Command Control, locomotives on the same electrical section of track can be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the National Model Railroad Association (NMRA). The NMRA has trademarked the term DCC, so while the term ''Digital Command Control'' is sometimes used to describe any digital model railway control system, strictly speaking it refers to NMRA DCC. History and Protocols A digital command control system was developed (under contract by Lenz Elektronik GmbH of Germany) in the 1980s for two German model railway manufacturers, Märklin and Arnold. The first digital decoders that Lenz produced appeared on the market early 1989 for Arnold (N) and mid 1990 for Märklin (Z, H0 and 1; Digital=). Märklin and Arnold exited the agreement over patent issues, but Lenz continued to develop the system. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extruded Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. ...

Hydrocal
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. Another imprecise term used for the material is stucco, which is also often used for plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum, lime, or cement,Franz Wirsching "Calcium Sulfate" in Ullmann's Encyclopedia of Industrial Chemistry, 2012 Wiley-VCH, Weinheim. but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens. Plaster can be relatively easily work ...
