Application fields of 3D printing （3D priting）
3D printing is also called a "material" made Additve (Manufacturing) technology, based on the computer model based on 3 d design, through software hierarchical discrete and nc forming system, using a laser beam, hot nozzle way such as plastic, metal powder, ceramic powder, and other special materials accumulated the massive tissue bond, superposition forming, eventually create physical product Manufacturing method.
The additive manufacturing characteristics of 3D printing have given it the application potential and prospect in various industries. However, due to the different concerns and needs of various industries, the requirements for 3D printing are also different. We can take a look at the cases of 3D printing in various industries.
(1) Transportation
In this area, and more are some market-oriented enterprises, in addition to the advantage of 3 d printing manufacture technology interested in additional, at the same time also very concerned about cost, so in the field of transportation, using 3 d printing to explore and develop much more than the batch application, of course, there is 3 d printing their own cost and the influence of batch capacity constraints.For some plastic 3D printed parts, it is more used in the development and verification of some parts.
There are also a few high-end models that use 3D printed parts for customization, such as the exterior panels of the BMW Minicooper and the window rails used in the BMWi8.
In the field of transportation, for plastic parts, due to the limitations of the types and properties of 3D printing materials at present, it is more in the research and development stage to do trial production.Due to high cost and low production efficiency, metal parts cannot be used in mass production parts, so they are more limited to performance improvement parts of high-end models.
(2) Aerospace
In the aerospace field, due to weight reduction and strength requirements, the proportion of complex structural parts or large heterogeneous parts in aerospace equipment is increasing, which is the advantage of 3D printing.At the same time, in the aerospace field, the performance requirements of parts are highly sensitive, relatively insensitive to the price, but also conducive to the adoption of 3D printing technology (mainly metal 3D printing).
(3) industrial equipment
In the field of industrial equipment, it is more common to see the core printing of injection moulds, and the parts manufacturing of some non-standard equipment, as well as the application of auxiliary tooling in production lines.
(4) consumer goods
In the field of consumer goods, the customization advantage of 3D printing is more utilized to give products more personalized characteristics, so as to attract different groups of people
(5) Medical treatment
Medical devices, especially customized medical devices, are a field that perfectly matches the characteristics of 3D printing, and currently have a good prospect in dentistry, orthopedic implants, rehabilitation orthopedic devices and other aspects.

Laminated glass and insulating glass are both composed of two or more original glass sheets, but the combination methods are different.
Laminated Glass is made of two or more original glass sheets with a transparent plastic lining between each sheet, which is formed by hot pressing and bonding. The original glass is ordinary flat glass or float glass. The lining is mostly made of polyvinyl butyral and other plastic films. Laminated Glass is divided into flat Laminated Glass and curved Laminated Glass according to its shape. According to the appearance quality, it is divided into superior products and qualified products.
Insulating glass is made of two or more original glass sheets, separated by isolation frames at the periphery, and sealed with sealant, so that a dry air layer is formed between the glass layers. The original glass sheet adopts flat laminated, toughened, heat-absorbing, heat-reflective, embossed glass, etc. The sealant adopts two-component sealant, which must meet the performance requirements of insulating glass. The partition frame can be aluminum frame, stainless steel frame, etc. According to the plane shape, the hollow glass has square and rectangular shapes. Requirements for the appearance of hollow glass: The inner surface of the hollow glass must not be splashed with adhesive which may hinder the perspective. The inspection items of sealing, dew point, ultraviolet radiation, climate cycle and high temperature and high humidity performance of insulating glass must be qualified, otherwise it will be judged as unqualified product.
“Will this LED track light head fit in the track in my home?” We always receive similar questions from potential customer of our online store, though we have clearly described it’s a LED track light head for H type, or J type, or L type track. It seems that many customers don’t understand what’s the meaning of H, J and L, and don’t know what’s the type of the track installed in their home.
Why the track gets these names, H, J, and L? Actually the names are from the first letter of three lighting brands, Halo, Juno, and Lightolier, each brand set up its standard for track and track head, and there is no changeability between three brands. It’s not easy to tell the difference from the track outside, so let’s take a look at the cross-section of three types of track. Unlike J type and L type, which only have 2 strips of wire, H type has 3 strips of wire, the upper one is grounding, and two opposite ones are neutral and live, H type is also the most common track in the market, and is widely recommended for new installation because of easy availability and low cost. The significant difference between J type and L type is the distance between contact measure cross, 7/8 inch for J type, and 3/4 inch for L type.
Accordingly, there are three types of track head adaptor.
Following is an H type LED track head, there are three pins on the adaptor, the top pin is the grounding pin, the opposite pins are neutral and live pin, and the pin to pin distance is 1 inch, which is consistent with the 3-wire system in H type track.
Following is a J type LED track lighting, there are two pins on the adaptor, and pin to pin distance is 1 inch, which are consistent with the 2-wire system in J type track.
The difference between L type track head adaptor and L type track head adaptor is very minor, so keep in mind that the pin to pin distance for L type track head adaptor is only 7/8 inch, not 1 inch for H type and J type track head adaptor. While the L type track system is very few in the market, so generally the 2-wire track system is J type track and J type light head.
You may notice that the above three track types we talked about now are all single circuit, which means that you can only control the track heads on one track as a whole group. For most applications, such as accent lighting for wall arts in the living room, or task lighting over the kitchen island, simple on/off and dimming as a whole group is enough. If you want to control the track heads on one track by two groups or to render complicated digital lighting effect, there are two circuits or three circuits track type in the market, and also corresponding track head for that purpose. The major difference from single circuit track is that two circuit track and three circuit track have more strips of wire, for example, two circuit H type track has 4 strips of wire.
So please check the track carefully before selecting the right track head for it. H type, J type or L type, and also single circuit, two circuits or three circuits?
