Doing It the Smart Way

3D-modeling can be classified as the hottest computer arts. Many experts consider it along with the programming of extremely complex and laborious task. However, painstaking attention will be over soon, because today’s market has a range of available devices, spatial scanning of objects.

3D-scan is a systematic process of determining the coordinates of points belonging to the surfaces of geometrically-complex physical objects (including components) with a view to obtain their spatial mathematical models that can be modified using the CAD-systems. Devices, which are used to scan objects called 3D-scanners. These devices not only simplify the process of creating 3D-models, but also allow solving this problem with the maximum degree of certainty in relation to the original source.

In spite of the fact that today the major consumers of 3D-scanners are designers and film-studio, the first customers of these devices have become automotive and engineering design bureau, whose need for equipment of this class led to the technology, used works.

As known, design cars and aircraft are still being improved with water tunnel, where the level of streamlining forms is determined by the positive impact of air flow. Mathematical algorithms that simulate the work of such systems are being improved, but in terms of their effectiveness, they are far from the present hydrodynamic blow and is unlikely ever to replace them completely. Therefore, the ideology of modern design bureau for many years almost unchanged and currently consists of three main stages.

On the first stage a drawing of the model is created, which is made of plastic material then. Next, form the model hydrodynamically rationalized in a tube blowing, and only then, with the help of scanning devices is transferred and processed by computer. Based on the volume of virtual models made new more accurate drawings, and from them already and are production models of cars, airplanes and other structures, for which important streamlined forms. As you can guess, the stage of sampling models is the most important in the process of creating products, since the accuracy of the process and determines the hydrodynamic characteristics of the final product. “Manual” mode digitizing is not very pleasant because, firstly, a very time-consuming, and secondly, inaccuracies associated with it, negate all the engineers’ efforts. Therefore the problem of accurate automated system for creating three-dimensional skeletons of volumetric bodies was faced by developers of computer equipment for a long time.

A good deal of success has been reached in this area since the market are some quite dissimilar systems capture three-dimensional surfaces and in the near future, many of them may become popular desktop solutions with massive proliferation. Actually about technology, allows you to scan 3D-model, as well as products produced on their base, and will be discussed in this article.
Currently there are a number of technologies that create three-dimensional images of the hardware means, ie without the usual 3D-modeling of specialized software packages. Divided the three-dimensional scanning technology into two types: contact and contactless.

Former imply the existence of a mechanical device such as “probe”, by which a computer transmits the coordinates of points selected by the operator. Positioning system of such devices is based on the work of mechanical sensors, similar to that used in the opto-mechanical manipulators “mouse”. Last enshrined in each attachment hinge “probe” and that the accuracy of these sensors and determines the accuracy of the device spatial scanning in general. Today such systems are becoming increasingly rare, and, according to experts, their fate in the future – scanning a relatively simple small-scale objects.

Contactless 3D-scanners are much more complex devices, which provide very sophisticated algorithms to create spatial frameworks. Thus, many of them used a double (additional to the main) Input the coordinates of the body. Many devices combine laser sensors (replacing mechanical “feeler” contact 3D-scanners) and digital camera, which is used for more accurate scanning, which allows to obtain models of objects with texture.

However instead of laser sensors, space can be used and more complex systems. For example, recently began to emerge of 3D-scanning-based ultrasound systems, an advantage over competitors which is the scanning mode phone with internal structure or body immersed in a homogeneous environment.

Modeling of three-dimensional characters, scenery, props and other objects can run a variety of methods starting from hand-made “sculpture sculpting” curved frame meshes using virtual instruments and ending with digitization of real objects in a special apparatus. Methods of computer animation varies widely too: from keyframing, when the set start and end positions animated character, to motion capture technology (Motion Capture), when the coordinates of 3D-objects transferred directly from the live actors’ movements are digitized by special sensors. Rendering is a process of rendering 3D-models on a computer after opening the virtual lighting and virtual cameras.

Methods used in constructing 3D-models can be different depending on the purpose, for a tractor to simulate and recreate a dinosaur – it’s not the same thing. When it comes to follow a complex animation, then, naturally, it is better to make a model manually in a 3D-package. The primary objective here is to build a correct working skeleton and create a neat and not too complicated in structure surface. Moreover, in such a simulation should mainly take into account the creative component, therefore in the process widely used sculpture, photographic materials, rough drawings and painting. Different methods of automatic numbering of objects (3D-scan) did not receive wide distribution. MicroScribe 3D devices readily available at a price (1000-3000 dollars depending on the size of the object, which can be processed), and easy to use, but can not digitize the texture of the object (and in fact drawing is one of the most difficult stages of modeling), so radically streamline the process of manufacturing models, so that you can give up manual work, and generally used only when there is insufficient qualifications 3D-designer.

Such systems represent a contact probe, which with the help of a few potentiometers mounted on the collapsible valve with swivel captures information about where in is head, and transmits this information in the form of coordinates in three dimensions by clicking the appropriate button . It is enough to make the necessary number of measurements, and you have a ready network for modeling the surface of the future models.

One of the main advantages of such systems is a high degree of control over the process of digitization of the operator. By the way, the device itself can be quite complex: it is, for example, a system of checks and is automatically compensates changes in temperature and corresponding expansion and contraction of the metal. When simulating the original object with a pencil or a marker applied the Line of Control, then the operator decides where to grid need to add details, and where to leave my job at detailing 3D-designers – it all depends on the purpose of the model. The purpose of such preliminary work is to make sure that the final grid to be accurate and the most rational. If, however, drawing on the model can not account for instead sculpt model.

In addition, after any digitization necessarily requires a fairly labor-intensive processing in 3D-package, but with proper planning created a grid such work can be highly optimized.

Unfortunately, this has deprived the benefits of more complex optical systems digitize 3D-objects (therefore, after their work, as a rule, the object model must be done again manually), possessing, however, another advantage is that they are automatically removed three-dimensional texture of the object (the texture of the surface), which can then be used with minimal revision. In this sense, optical scanning technology of 3D-objects is more advanced. Of the three main areas in which developing the specified technology (scanning point by point, according to zones and zones), the best results showed scanning technology for the bands (usually with light markings).

In the process of work under some serious architectural or engineering project it is often difficult to identify the various mistakes and shortcomings of using only the screen and, besides, not everyone can easily navigate in three-dimensional projections. Once you have a real physical model of the future product, you can identify and resolve various mistakes, correct the design process. The prototype can be used for marketing purposes, for advertising, when determining the cost of manufacturing, as well as to find common ground between designers and clients quickly, thereby reducing time-to-market.

Usually to obtain some models people do it by hands or by special machines. But to manufacture this model few weeks to several months are spent, resulting in higher costs for new product development and delay in the release of new products.

With penetration into the area of design technology 3D-graphics appeared and actively developing new computer technology of the so-called Rapid Prototyping, or three-dimensional printing. They provide an opportunity to receive physical details and the model without instrumental production that is by automatically converting data from 3D-representation in the physical model by pressing just one button. Thus, at the completion of the virtual 3D-model can give the command “Print”, similar to how we do it in a text editor, and a few hours or days, depending on the size and complexity of the project, obtain a physical model.

After old methods of prototyping, pre-mid 80-ies, RP-system ushered in a revolution in technology. Instead of waiting for the model for several weeks, designers can now receive them in a few hours or even minutes.

Currently on the market, there are various RP-system, producing models with different technologies and from different materials. However, all systems for quick prototyping, available today, operating on similar principles of construction of physical models, which are as follows:

• reading of three-dimensional geometry of the 3D-system (usually a solid model from CAD-systems or models with closed surface contours);

• partition of 3D-models of the simplest components or layers in cross section with a special program that comes with hardware for 3D-printing;

• construction details in the bulk structure of the polymer or layer by layer until, until will be received physical prototype.

On professional market a number of RP-printers are offered, which vary by class, price and opportunities. The cheapest are monochromatic 3D-printers, which make the model of a small amount for use in conceptual design and rapid prototyping. Prices of these systems begin with a few tens to thousands of dollars. The most expensive is a production-oriented system, which make accurate color models of large volume. The cost of such machines is hundreds of thousands of dollars.
We hope that this article helped you to understand how 3D scanning work and why it’s so popular in the modern world.

3D-growing is one of the most simple and accessible technologies of rapid prototyping. With the help of 3D-prototyping is the design phase where we can estimate the result and make the necessary changes in the project – a three-dimensional prototyping can thus reduce the costs associated with product development.

World practice shows that the prototyping of products at the design stage allows reducing development time and technical training for new products in 2-4 times. Thus, it is clear that neglect the 3D-cultivation is simply not feasible.

Technology of prototyping allows you to create low-cost models of any complexity. With the help of 3D-prototyping you can not just materialize projects in production, but also, for example, to grow layout country house, to assess its strengths and weaknesses, which on paper is simply not visible.

Before 3D-prototyping Technologies was invented models were made by hand, so the cost of prototyping was high. Nowadays almost everyone can afford 3D-cultivation.

If you want to order prototyping products you can use 3D-printer that is the best solution for rapid prototyping.

When technology 3D-prototyping is used the cost of the finished layout in times less than the cost of a similar order in the model workshop. At the same time, thanks to rapid prototyping to visualize project requires very little time, and mock-ups are performed with computer accuracy.

With the help of rapid prototyping it is possible to make the layout area of any area to evaluate the appearance of the complex as a whole. Well, the fact that technology of prototyping allows you to create color models, makes the layout as close as possible to the reality.

Rapid prototyping is used everywhere, so there are services for specialists from various fields. For example, the services of rapid prototyping are often demanded by medical institutions. In addition prototyping technology is used in the production of low-circulation, for example, in the manufacture of souvenirs.

3D-Scan is a systematic process for determining the coordinates of points belonging to the surfaces of geometrically-complex physical objects (including components) with a view to obtain their spatial mathematical models that can then be modified using the CAD-systems.

Scanning is performed with a step, which value depends on the required degree of elaboration of the surface relief. Scannable surface appears first in the form of so-called “point cloud”, which is then covered with the approximating surface, reproducing scanned with a certain accuracy.

3D-scanning is basicly used:

for creating 3D-models of hand-made art of relief items (medallions, sculptures, bas-relief, high relief, etc.) with a view of the industrial playback;

for creating 3D-models made by hand of designer pre-elaborations industrial products, in particular, with their subsequent modification of the methods of computer graphics;

for creating 3D-models of existing dies, molds and other products of complex shapes, such as unique, if needed, their changes, repairs or repeat;

for measurement of geometrical parameters of products, which can not be measured by standard methods.

Rapid prototyping is a modern and convenient way to make models. And we are going to tell you about one of the ways of rapid prototyping such as vacuum casting. Vacuum casting in silicone molds is a modern technology of manufacturing products from materials polymerized by chemical reactions or with low temperature curing. The advantage of this technology is its simplicity and short time of manufacture of foundry equipment from the two-component silicones. It uses the properties of silicone very accurately reproduce the size and texture of the surface of the master model, low tendency to adhesion, and elasticity of the material, allowing, in some cases, you simply solve the problem of availability of parts from undercuts. Preliminary degassing and casting in vacuum avoids the porosity and surface defects in castings.

Due to speed tooling, this technology allows you to get small (up to 20 – 50 pcs. quickly one form of silicone) in a batch, including the hull parts of devices, ergonomic handles, wiring accessories and other parts of complex shape.

The sizes of cast parts are limited to the greatest possible dimensions of the form (900 x 750 x 750 mm) and a maximum weight of the filling compound (up to 5.5 kg).

When it is necessary to ensure the screw fastening parts, a plastic can be filled with fittings with threaded holes.

The color of products in the desired color is done by adding in the foundry composition of the pigments. The customer can provide coverage corps devices conductive material to electrostatic discharge or shielding from exposure to electromagnetic fields.

Curing for the manufacture of master models can serve as a model provided by the customers (the materials as agreed), and the prototypes made by centers or 3D-printing.

In injection molding technology for the burned models the model of polystyrene for castings are used.
Polystyrene is typically used for making fully working prototypes with high accuracy performance, which can be used immediately after their manufacture.
It endures high mechanical and thermal loads
In casting technology to land the model of polyamide is applied.

The advantages of Rapid Prototyping Technologies (Rapid Prototyping)

Making models of any complexity with high accuracy
It does not require tooling
It shortens the time from design to manufacturing
Prototype allows evaluating the appearance of parts
It helps to check structural reliability and to make the assembly
It helps to check the performance of parts or assembly.
It reduces costs for design and production preparation
In other areas

as design layout and exhibition designs;
as master model;
as assembly units for checking layout decisions;
for a primary test (functional model);
as alternative foundry molds;
for translating design ideas
for manufacturing exclusive souvenirs
for creating models for jewelry and artistic cast

So you may see yourself that this method is not only convenient but also allows to make new models faster and better.

Rapid prototyping, vacuum casting in silicone molds and three-dimensional laser scanning are key technologies to update promptly the range of products, respond quickly to the constantly growing and changing demands of consumers, reduce training costs of production and its duration. These technologies are used at almost all stages of preparation of industrial products: when considering the idea of the feasibility issue, exploring design, construction, verification, collection, testing, refining, marketing research, the creation of devices and so on.

Engineering Centers has a wide range of technological capabilities that address a variety of tasks in these fields:

Getting spatial mathematical models of products using CAD tools or space laser scanning of existing designs;

Rapid prototyping techniques FDM (ABS-plastic ) and 3D-printing (of the powder, similar to gypsum);

vacuum casting in silicone molds plastics with different physical and mechanical properties, as well as injection waxes.

Plan to order fulfillment is pretty simple:

1) The customer provides a sketch, a drawing or a 3D-model, usually by e-mail to clarify the stated number of manufactured products, color and texture of the surface, the need for special coatings, such as shielding or conductive ;

2) specialist engineering center calculates the price and duration of works, if necessary, performed clarification and harmonization of technical requirements for products and delivery;

3) on reaching agreement of the parties to execute the required documents (contract, bill, etc.);

4) order is passed in the production

In fact, prototypes of products is a layer-creation of the physical structures on the basis of the developed mathematical model. Among the benefits of technology: the visibility, shorter pre-production, as well as reducing the cost of construction and design. Rapid prototyping involves several steps, the first of which is the mathematical modeling. This technology is to develop a mathematical model of a product in a format STL. Then, to refine the required types of surface texture is carried out to improve the prototype. Note that if you have a sample of parts, manufacturing of the prototype is not required. You are provided of a sample that can be used as a master model in the production of silicone tooling. Prototypes of products also include the refinement of the technologies, direct manufacturing of models and the final revision.
Rapid prototyping” is the common name of a number of new automated technologies, which came in the last decade to replace or assist in hand-made models, models or prototypes. Prototypes, in particular, are the first full-scale and often functional, samples of products of the new design or design execution issued, usually of 1-3 pc.

Usually two methods of rapid prototyping are used. They are FDM and 3D-printing. FDM-prototyping is a “growing” product samples in a special installation method of layer deposition half-melted plastic filament emerging from the die, in accordance with the control program. 3D-printing from finely divided powder layers lay out and glued with a special compound.
