A well planned and managed interior of a house is the key to make any house attractive. No house can be so effective unless it is equipped with mind blowing interior design. And to make it possible, it is quite wise to use 3D interior design and 3D interior models for making your house a dream house.

Now before starting, let’s know about what 3D interior design and 3D interior models are all about, how it can be so useful for interior designing of a house. 3D interior design – as its name suggests, can be defined as a set of pictorial representation of your house’s interior architecture. A set of architectural designs are produced that mention each technical specification about any house’s interior geometry.

Also visualized 3D architecture interiors rendering of residential buildings are covered in developing accurate 3D interior designs. Now talking about 3D interior models, these models are developed using a specialized technique called “3D Architectural Modeling”. This technique is about creating effective and efficient 3D models of any building types such as residential, commercial and industrial buildings.

Using this technique, a set of accurate 3D interior models of residential house are developed as per user’s specifications. These models are considered as templates of any house’s proposed architecture design. 3D interior models give an exact visualization of about how your house will look when it gets completed. As per these ideas, user will be quite aware about his house’s interior and can easily plan out his future activities to get the job done.

While creating such 3D interior models and 3D interior designs, custom furniture and fixtures required along with the texture and lighting specifications should be taken into consideration. Certain parts of a residential house like kitchen, bathroom, bedroom and living room should be well expressed and should be given more weightage while preparing precise 3D interior design and 3D interior models. Using them, one can surely make house interior better and effective.

3D prototyping techniques are a group of procedures that can quickly produce a tangible model of a product by using 3D CAD software. Another name for 3D prototyping is rapid prototyping. This process will create a solid physical structure of the product instead of a 2D layout. The prototypes can be used in different ways. For example, a visible image of the product can be use for communication and marketing purposes. As well as, a visual representation of the product can be used for testing and diagnostic purposes, tooling and rapid manufacturing.

Rapid prototyping is made up of a few basic steps. The first step is creating a design model of the product by using computer aided design data. The next step involves converting the computer aided model design into a stereolithography form. The stereolithography form is chopped to develop a cross sectional model. This will create a constructed band and the band will be placed topmost of another band. The final step is a clean and finished model.

Rapid prototyping has six 3D prototyping techniques that involve a variety prototyping apparatuses. In addition, the prototype apparatuses are stereolithography, selective laser techniques, laminated object manufacturing, fused deposition models, three dinensional inkjet printing and solid ground curing.

Stereolithography is one of the first prototyping techniques. This technique uses liquid polymer which is photosensitive and solidifies with the use of an ultraviolet light. On the other hand, stereolithography is considered to be the standard of rapid prototyping techniques. In 1988, the stereolithography machine was built by 3D systems. One of the disadvantages of early stereolithography was that the model created from this method would produce a deformed and brittle model.

The laminated object manufacturing technique was created with the Helisys machine. The process involves taking adhesive sheets and layering the sheets to create a prototype. In addition, the laminated paper is put together with a sticky substance and put on a spool. Laminated paper was one of the first substances used with this technique.

Selective laser techniques are a method that was developed by Carl Deckard. Deckard created the method as a thesis project to complete his Master’s Degree. This method uses powdered metal, nylon and elastomer to make a solid object.

Fused modeling is a technique that makes use of ejected thermoplastic filaments. The thermoplastic filaments are heated from the end. The tip moves on an x and y field range.

The ground curing technique was developed by Cubital. Ground curing is similar to the stereolithography method. The technique involves using ultraviolets light that heats and harden the polymer. Solid ground curing and stereolithography is different because of the way the material hardens. The ground curing technique makes a complete layer of the product at a time.

The techniques make it possible to create a quick prototype to meet important deadlines. Furthermore, 3D prototyping techniques are a fast way for businesses to create models to promote their brand.

No matter if part of the coastline along the Atlantic or the hilly areas of Litchfield County are being mapped, Connecticut surveys incorporate tried-and-true and modern techniques. Surveying, for boundary or civil engineering purposes, is the technique of determining two- or three-dimensional points on the surface of the Earth and the angles between them. These points are used to establish land maps and boundaries. In addition to the technical aspects involving geometry, trigonometry, and engineering techniques, Connecticut surveys need research and observations, taking into account and historical documents or records for the area.

Measuring all points, however, is a time-consuming process and takes time away from surveyors that need to be conducting research. Laser scanning, however, is one technique that speeds up this process. Used for many Connecticut surveys, this technique captures these points on the surface of the Earth with beams of light. In addition to speeding up the surveying process, the device also makes capturing complex and difficult to reach surfaces easier.

Used commonly for civil and structural engineering, a laser scanner sends out a point of light in the direction of an object being surveyed. The scanner, then, times the light from the moment it leaves to when it reaches the object to when it returns, and this figure becomes a point on a three-dimensional graph (X, Y, and Z). The laser scanner continues sending out thousands of beams in the direction of the object, and a point cloud is formed on the three-dimensional graph. Once all the points in the cloud are connected together, the scanner calculates the angles between each of the points, and a three-dimensional, computerized image forms.

At this point, however, the survey is not complete. Although the physical data from an object or land has been gathered, two-dimensional images are needed for many engineering projects. The three-dimensional image on the laser scanner can be traced from several angles in order to make two-dimensional drawings.

A resin composition suited for rapid prototype is provided comprising an actinic energy radiation-curable silicone composition, an actinic energy radiation-sensitive polymerization initiator, and an actinic energy radiation absorber. The resin composition experiences little viscosity buildup and maintains fluidity during long-term storage at elevated temperature, and is effective in rapid prototyping or shaping by stereolithography using any actinic energy radiation.

This invention relates to a resin composition suitable for use in rapid prototyping or stereolithography technique to form three-dimensional objects having improved rubber physical properties.

Recently, a technique of optically forming a three-dimensional object from a photo-curable liquid resin composition on the basis of data output from a three-dimensional CAD system is on widespread use because the desired three-dimensional object can be manufactured at satisfactory dimensional precision without a need for molds or the like. This technique is broadly referred to as rapid prototyping and specifically as stereolithography. With respect to this technique, JP-A 56-144478 (Kodama) disclosed a method of forming a three-dimensional object by supplying a required amount of optical energy to a photo-curable resin, and JP-A 60-247515 established a practically acceptable method.

A typical method of optically manufacturing a three-dimensional object involves selectively irradiating an ultraviolet laser beam to the surface of liquid photo-curable resin contained in a vat under the control of a computer to harden the photo-curable resin so that a photo-cured resin layer having a predetermined thickness is obtained, then supplying a layer of liquid photo-curable resin onto the cured resin layer and then likewise irradiating an ultraviolet laser beam to the liquid photo-curable resin layer to form a cured resin layer contiguous to the previous one, and repeating the laminating operations until a desired three-dimensional object is obtained. Great attention has recently been paid to this rapid prototyping technique because a three-dimensional object of complex configuration can be formed with ease and within a relatively short time.

To actinic energy radiation-curable resin compositions for use in the rapid prototyping are imposed many requirements including high cure sensitivity to actinic energy radiation, good resolution of a shaped object, high precision of shaping, a minimal volume shrinkage factor upon curing, good mechanical properties of cured product, good self-adherence, good curing properties in an oxygen-containing atmosphere, a low viscosity, resistance to water or moisture, minimal absorption of water or moisture with time, and dimensional stability. Prior art resin compositions known to be used in the rapid prototyping include photo-curable acrylate resin compositions, photo-curable urethane-acrylate resin compositions, photo-curable epoxy resin compositions, photo-curable epoxy-acrylate resin compositions, and photo-curable vinyl ether resin compositions.

There is a need for resins which when processed by the rapid prototyping technique, exhibit “rubber-like property,” that is, the nature that they easily undergo deformation, without rupture, under an applied stress and resume the original shape after the stress is relieved. However, the structures obtained by curing these resins are basically rigid and exhibit the nature that they fail when a stress above a certain level is applied.

A number of materials that exhibit rubber elasticity independently of photo-curing are used in the industry. Typical examples include ethylene-propylene rubber, butadiene rubber, polyurethane rubber, silicone rubber, and fluoro-rubber. However, the resin which cures into a practically acceptable state upon exposure to actinic energy radiation is limited to the silicone rubber.

Although the compositions described in these patents cure upon exposure to actinic energy radiation, their cure rate is yet too slow to apply to the stereolithography so that they could not be used in practical rapid prototyping. Even when they are cured to completion with the time taken therefor being neglected, the resulting rubber model will become embrittled shortly and exhibit no longer rubber elasticity. It would be desirable to have a resin which is amenable to the rapid prototyping or stereolithography and exhibits and maintain rubber elasticity.

An object of the present invention is to provide a rapid prototyping resin composition of the actinic energy radiation cure type, which has improved storage stability and aging stability prior to exposure to actinic energy radiation, experiences little viscosity buildup during long-term storage at elevated temperature, has high cure sensitivity to actinic energy radiation, typically light, and when exposed to actinic energy radiation, produces in a smooth and efficient manner a cured part which has improved dimensional precision, shaping precision, water resistance, and moisture resistance, and exhibits stable rubber elasticity over a long term, especially elastomeric physical properties as demonstrated by an elastic recovery ratio of at least 80% after elongation of at least 100%.

The inventors sought for materials which exhibit rubber physical properties that lend themselves to rapid prototyping or stereolithography. We have found that a silicone resin composition of the actinic energy radiation cure type, especially a silicone rubber (i.e., organopolysiloxane elastomer) based material comprising an alkenyl-containing organopolysiloxane, a mercapto-containing organopolysiloxane, and preferably an alkenyl-containing MQ resin is an effective rapid prototyping resin, and that an actinic energy radiation-curable resin composition obtained by blending therewith an actinic energy radiation-sensitive polymerization initiator (especially radical polymerization initiator) and an actinic energy radiation absorber is amenable to shaping using actinic energy radiation, typically rapid prototyping or stereolithography. Although the resin composition has high cure sensitivity to actinic energy radiation and rapidly cures when exposed to actinic energy radiation, the resin composition is easy to handle in that it has improved storage stability and aging stability, and when stored for a long time, even at elevated temperature, experiences little viscosity buildup and maintains a flowable state compatible with rapid prototyping.

Upon exposure to actinic energy radiation, the resin composition cures into a photo-cured or rapid prototype part which has improved resolution, shaping precision, dimensional precision, mechanical properties and outer appearance, and among the mechanical properties, exhibits improved rubber elasticity as demonstrated by an elastic recovery ratio of at least 80% after elongation of at least 100% which has never been achieved with prior art resins.

Do you have any idea about what exactly a 3D model is? If you have ever seen a statue or monument in your existence, you by now be acquainted fairly a little regarding 3D Modeling. 3D Modeling is not anything but the formation of a personality or a representation of a thing having three dimensions (as in actual world). 3D models are crafted by a 3D model designer, using the procedure, techniques, methods and apparatus made available by computer software.

The software like 3DS Max, Maya, SoftImage etc, we use for the purpose of 3D Modeling and animation tool. The tool will provide a set of tools or apparatus that a 3D model designer can make use of to carve or model, an object in his thoughts, into a 3d computer illustration. This 3D model can be changed, animated or turned into a movie in accordance to the need of 3D model designer. A 3D model designer should be creative and innovative.

There are chiefly five types of 3D modeling, which have been discussed below:

# Primitive 3D Modeling: This is a very fundamental modeling technique and consequently has quite a few draw backs too. The software tool like 3DS Max, Maya etc provides a set of 3D primitives like spheres, boxes etc. The 3D model designer modifies these shapes to suit his/her character modeling requirements.
# NURBS 3D Modeling: it stands for Non Uniform Rational Bspline it is a mathematical curve, represented using a set of equations. If we see this modeling technique from an outer view, all we see is a set of simple curves that we call NURBS.

# Surface 3D Modeling: it is an extensively accepted modeling technique used largely for organic modeling. In this modeling technique, the 3D model designer generates a spline cage profile for the 3D character.

# Polygonal 3D Modeling: it is used for both in organic and inorganic 3D modeling. The basic principle behind this modeling technique is as the 3D model designer illustrated the shape of the model he desires to generate using the polygon tool. Then the polygon will get subdivided and extruded, so that the model gets the 3D form.

# Sub-division 3 D Modeling: it has control points and lattices that can be dragged and stimulated, to modify the original polygonal model that lies underneath. This modeling technique also permits the 3D model designer to choose the level of modification to be done in an exact area.
3D effects are frequently attained without wireframe modeling and are sometimes impossible to differentiate in the final form. Some graphic art software includes filters that can be applied to 2D vector graphics or 2D raster graphics on transparent layers.

Advantages of wireframe 3D modeling over exclusively 2D methods include: Flexibility, Ease of rendering, automatic calculation, rendering photorealistic effect, accurate photorealism.
