3D printers can be used in any industry as long as those industries need models and prototypes.Industries where 3D printers are in high demand include government, aerospace and defense, medical devices, high tech, education, and manufacturing.
Aerospace and defense.
Engineers at GE's China R&D center are still buried in 3D printing technology. Just a few days ago, they used 3D printers to successfully "print" an important part of an aero-engine. Compared with traditional manufacturing, this technology will make the part cost reduction of 30%, 40% shorter manufacturing cycle. Too late to celebrate the happy results, they hastily embarked on a new journey. Little known fact is that they have been "secretly" developing 3D printing technology for ten years.
Medical industry. An 83-year-old man suffering from a chronic bone infection had his jawbone "printed" by a 3D printer, the world's first case of a human skeleton made from 3D printed products.
Conservation. Museums often use sophisticated alternatives to protect original works from environmental or accidental damage, while replicas can spread the impact of the art or artifact to a wider audience. The Smithsonian, for example, used a giant 3D-printed replacement of the original Thomas Jefferson in the place of the original sculpture because it was to be placed on display in Virginia.
Architectural design. In the construction industry, engineers and designers have embraced building models printed on 3D printers as a method that is fast, inexpensive and environmentally friendly while being beautifully produced. It's perfectly suited to the designer's requirements and saves a lot of material at the same time.
Manufacturing. The manufacturing industry also needs a lot of 3D printed products, as 3D printing is much better than traditional manufacturing in terms of cost, speed and accuracy. And 3D printing technology itself is perfect for mass production, so manufacturing can benefit so much from utilizing 3D technology that even quality control is no longer an issue.
The food industry. That's right, "printing" food. Researchers are already trying to print chocolate. Perhaps in the near future, a lot of food that looks exactly the same will be "printed" using food 3D printers. Of course, by that time, it will probably be many times more expensive to make the food by hand.
In daily life and production, laser technology is more and more widely used, the following small introduction to the specific application of laser machines, in which industry will use the laser machine:
1, paper cutting (paper cuttings, cell phone key film, cards, etc.)?
Paper cutting is generally used in small models, double focus mirror, because the lavender paper is relatively thin, the graphics will be relatively fine, small air pump is most suitable, can use the radio frequency tube is more ideal. Cell phone button film is also currently more customers use, generally used for sampling. Usually small models, with 50mm focusing lens. Speed in 0.5-1 m / min, light intensity within 35%, graphic size of basically all customers to modify the map to achieve by changing the cutting seam size to add. But the requirements for the honeycomb bottom plate flatness is also very high.
2, fabric embroidery industry?
Fabric cutting is generally used in high-speed destruction machine CM or TM series, generally use 50mm focusing lens, single-layer cutting normal speed is 5 meters / min, light intensity of 40%, the size of the power of the air pump, honeycomb backing board good and bad and flatness, the size of the light intensity will affect the effect of the destruction of the fabric. The greater the light intensity, the greater the heat radiation, light will produce a gap. At present, the biggest problem of cutting is the phenomenon of yellowing, put the fabric flat on the honeycomb substrate, open the extractor fan, timely extraction of smoke and dust, to prevent the cutting of smoke and dust produced by the fabric smoked yellow, open the air compressor to ensure that the blowing suburbia, blowing away the cut seam within the impurities of volatiles and smoke and dust, blowing the use of inert gases (such as nitrogen) is more desirable.
(1), the cutting of ordinary fabrics (non-woven, polyester, indeed, silk, satin, twill, etc.) fabrics belong to the thin and light materials, in order to ensure the effect of the incision, we generally use 50mm focusing lens, spot fine, small slit. Turn on the laser machine external equipment (pumping, blowing), the fabric flat adsorption on the honeycomb base plate, blowing first with a high-power air pump air compressor. Speed: large graphics or graphics external curve smooth part can be used at a higher speed, CM machine, for example, generally in the 3-10 m / min; small graphics or graphics internal curves or corners of the part of the use of low-speed, generally in the 0.5-3 m / min, light intensity: the matching principle of light intensity is a high-speed with a large light intensity, low-speed with a small light intensity, the general adjustment of the time when the light intensity of 30-60; low-speed for the 18-35%. And to have the size of the light intensity difference, generally in the 5-15% or so, in order to realize the cutting straight line and curve acceleration and deceleration of the size of the light intensity match.
(2) the cutting of special fabrics (white cotton, dust-free fabrics, fabrics containing PC and plastic components, etc.) process requirements: white cotton is required to cut without yellowing, dust-free fabrics do not change color after cutting, the incision is not hardened, for these two types of fabrics, we have to choose 50mm focusing mirror, preferably imported radio frequency laser, to ensure the quality and stability of the spot. Turn on the pumping and blowing (turn on the air compressor when cutting white cotton cloth), and it is recommended to use nitrogen gas if possible. Speed: 1.5-3 m / min, light intensity: 20-30%, as to achieve the purpose of non-yellowing and the incision does not become hard, we have to use the medium speed to match the appropriate intensity of light to cut, too fast we have to increase the intensity of light, so that the incision will be due to high temperature scorching of the large intensity of light and discoloration or hardening, the speed is too slow light energy in the incision stays too long, and can not achieve the desired results. In terms of the current equipment and technology, to perfectly achieve this process requirements have some difficulty, especially the thicker white cotton surface, the incision will have discoloration, dust-free cloth will also have a slight hardening of the appearance.
(3) double-layer fabric (self-adhesive) cutting (the upper layer cut through and the next layer of no damage or slight damage)
This is the electronics industry processing process, the laser's light control accuracy, stability and light intensity and speed of the matching has high requirements, at present, we generally use the domestic glass tube prototypes, basically to achieve the effect, but for large-volume processing, it is recommended that the use of imported RF Laser. Turn on the ventilation blowing, the fabric flat adsorption on the honeycomb, and to adjust the flatness of the four corners of the honeycomb bottom plate. Speed light intensity setting: specific parameters depending on the material, both can achieve a better match on the line, generally on a layer of 1.5-6 meters or so, the light intensity of 18-35 or so; the next layer of light intensity speed has no specific requirements, in order to ensure a better quality of the incision under the premise that you can open as fast as possible, and in addition to the setting of the light intensity should be the difference between the two, so as to ensure that the depth of the cut to achieve consistency in acceleration and deceleration. . (Some materials can not blow)
(4) trademark woven mark cutting (fabric, woven mark, trademark)
Trademark cutting we are currently the main use of automatic camera and semi-automatic manual cutting of the two modes of work, the accuracy depends mainly on the debugging of the machine and the positioning of the accuracy of each woven mark out of some differences in each completely along the edge of the cut is not possible. For the cutting requirements we use the way with ordinary fabric cutting is almost, but because of the woven mark trademark in the precision and hardness are much larger than the fabric, in the light intensity and speed is also a big difference. Speed and light intensity depending on the specific processing pieces, reference parameters: speed 1.2-5 m / min, light intensity 20-55%.
3, knife mold plate cutting?
The knife mold of the knife seam is mainly 0.45mm and 0.7mm two kinds, the requirements of the knife seam is more stringent, and the requirements of the seam width is basically the same. The material is medium fiberboard and a 6mm glue board, these materials are relatively hard, can only be cut at a slow speed, so must be equipped with air compressor. 0.45 with a 63.5 lens, the speed is generally 0.2 meters to 0.4 meters per minute, 0.7 with a 50 lens, thickening the line of 0.3mm or so to cut twice, the speed is generally 0.3 to 0.5.
4, wood cutting And carving ?
Wood engraving is mainly used in die-cutting boards, wood models, veneer appliqué, hanger engraving, wooden picture frames and so on. Wooden board materials are plywood, solid wood, medium density fiberboard, the current application of the most cutting is plywood. General plywood distinction 3mm, 5mm, 7mm these can be cut, normal 3mm plywood sample speed in 1.2m/min can be cut through, some solid board can be cut 10mm. depending on the specific circumstances of the material. 6mm die-cutting board cutting the best use of 63.5mm focusing mirror, speed in 0.2-0.4m/min, light intensity of 75-80%, plus a large air pump or air compressor, the effect is more ideal! The result will be more ideal. Wooden board model cutting general thickness of 3 ? mm or less, the general speed is 0.5-1.2 meters / min. Wood veneer parquet cutting is generally equipped with double focusing mirror, demanding customers, try to use radio frequency tube. Because the radio frequency tube spot delicate,, small cut seam. Hanger engraving-carving is best to use a small area of the engraving machine. Wooden plate engraving according to the size of the graphics, the requirements of the effect and set the speed of the machine. Some customers want to carve more black, you can choose off-focus engraving. The size of the air pump affects the degree of scorching.
Hot diamond template cutting and engraving, hot drilling template a variety of commonly used materials, cutting with: hot drilling paper, engraving with (density board) or thin acrylic, hot drilling paper cutting is generally used 50mm focusing mirror, open the blowing and suction, will be adsorbed in the honeycomb cardboard flat, there are no special requirements for the cutting parameters and processing technology, due to the cutting part of the graphic will not be too large, the speed is generally 0.5-3.5 m / min, light intensity value is generally about 18-40, as much as possible to increase the blowing to reduce the discoloration of the edge of the incision. Hot diamond plate engraving speed in 10 meters / min, light intensity of 35%, the resolution of 600 dpi or more. Specifically depends on the size of the hot diamond, the larger the hot diamond, hot diamond thickness is also thick, hot drilling board to carve the deeper
5, leather cutting and engraving?
Leather is mainly used for shoe engraving, handbags, leather gloves, bags and so on. Production process of some small holes, surface hook line or cut pattern, process requirements: hook line surface is not yellow, carved out of the material color, leather cutting edge is not black, carved to be clear. Materials are synthetic leather, PU leather, PVC artificial leather, leather wool, semi-finished products, and a variety of leather fabrics and so on. Engraving speed depends on the size of the graphic, small pattern drawing line relative speed is a little slower, speed in 0.8 meters / min, large pattern cutting speed in 1.5-3 meters / min, light intensity in 75%, general leather can cut through. Leather cutting a little slower, speed at 0.4-1.2 m / min, light intensity at 60-75%, leather cutting incision will be black, air cutting, but the incision will form an oxidized layer, leather and other requirements of the incision a little bit of black, it is difficult to meet the requirements; must be processed, such as cutting can be blackened with the edges of the rubber clay to dip away. There is also cut out the odor, so far for this reason, there is no way to solve. For the use of nitrogen cutting requires the use of high-pressure nitrogen, slow, high cost, but cutting without oxidized layer, cutting effect is better. Not the same leather, choose not the same cutting methods, such as artificial leather marking can be wet water before marking, the effect is more ideal. Genuine leather cutting surface can be added to the patterned paper to prevent the surface from yellowing; edge blackening, the need for special treatment.
6, two-color plate engraving and cutting?
Drawing according to the material color, the same image of a character in black and white two-color plate carving out the exact opposite effect. Engraving is generally used 50mm focusing mirror, usually with a resolution of 350-500dpi, speed is generally 8-20 meters / min, light intensity 20-30%, the size of the air pump affects the degree of engraving burnt. The bigger the blowing, the more fuzzy the carving effect, so it is best not to blow, but also to take down the jet cup ｛In the case of not blowing the carving will be the air nozzle blocked. The cutting of two-color boards will be a bit melted, the edges will be blackened, and the edges must be scraped with a razor blade.} Speed of 1 meter / minute, light intensity 50-60%, sometimes can be added to the film cutting, cutting the film after tearing off the edge of the surface will be more ideal.
7, lamp engraving and cutting?
Lighting materials: basically PVC, there are surfaces with cloth, there are also with paper. Production process has a hole, carving, cutting flowers and so on, some need to focus off the drawing line, there are cutting flowers, depending on the size of the graphic, the general cutting speed of 1.5 meters / min, light intensity at 45%, the choice of a large gas pump or air compressor, the edge of the edge will not be yellowed. Engraving are generally 15 meters / min, light intensity of 30%, the resolution of 200dpi are reached at the bottom of the flat.
8, marble carving?
General marble engraving using pure black material, nothing miscellaneous. So that after image processing on the carving out of the figure of a clear image. Engraving speed in 8 meters / min, light intensity in 40%, the resolution is 600dpi, screen is 45 lines / inch.
9, carton packaging industry (rubber sheet)?
Rubber plate engraving is the main use of models YM series, generally choose 50mm focusing lens, format using > ? PLT and BMP two kinds of PLT is mainly used to hook edge. The two formats have their own advantages, case-by-case analysis. When the carving of the word height greater than 10mm or pattern stroke lines greater than 1.5mm, you can use the hook edge way, a show 7mm single-layer ordinary rubber version, for example, hook edge when the surface plus wet newspaper, with leakage of jet cup, to prevent blowing too much wet newspaper blowing up, so as to make the hook out of the line more delicate. At this time the general adjustment of speed: 0.5-0.8 meters / min, the faster the speed, the larger the sawtooth; light intensity adjustment: 20% -50%. With the different depths to be adjusted, if you want to deeper light intensity of up to 60% -70%. Double rubber version is: 4mm double rubber version of the light intensity to reach 1.5mm deep, the speed is generally adjusted to 0.5 meters / min, light intensity of 45%, depending on the circumstances. If you carve the word height is less than 10mm, this is generally used to carve, this time the speed is generally adjusted to: 10-15 m / min; light intensity adjustment for the top depth of 18% -28%, the depth of 55% -75%, the slope of 0.8-1.5 between the resolution of the general 500-600dpi, the denser the text or the smaller, the light intensity is also to set up a small slope is also set up relatively small.
10, acrylic cutting and engraving?
There are many kinds of plexiglass materials, imported and domestic difference is very big, imported plexiglass cut out very smooth, some domestic impurities are too much, will blister. Acrylic cutting generally use low-speed machines, because the laser tube power is not very large, and thin material precision requirements are high. General speed is not more than 3 m / min, such as the CMB series, linear guide produces a fine grain, smoothness is also good. At present, we have five kinds of focusing mirrors to focusing mirror focal length distinction for (50mm \63.5mm \75mm \100mm), plus double focusing mirror.
Introduced according to the thickness of the material:
Thick material cutting (10-20mm)
10mm or more plexiglass is generally used 75mm focusing lens, 25mm or more plexiglass 100mm focusing lens, the deepest cut 32mm plexiglass. 10mm plexiglass cutting: the cutting speed of the general for the 0.08-0.12 m / min, the light is also good. 0.12 meters / min, light intensity 60-70%. In the light intensity of 60% of the time when the most stable, leaky jet cup to adjust the size of the gas flow, so that the edge of the smoother. Because the greater the blowing wind cutting the melted object is aided by high-pressure gas blowing back to the plexiglass to form an unsmooth surface. Try to adjust the wind down. Sometimes, customers need to add paper or film cutting, this time the wind can not be too small, otherwise it will catch fire. Cutting plexiglass speed and light intensity must be a good match, the slower the speed, smoothness is not the better. 15mm or more plexiglass is best to use imported high-power laser. Plexiglass engraving with a leaky jet cup, try not to carve too deep, carve too deep it is difficult to reach the bottom of the flatness, the more the gas will affect the effect of the carving edge, to carve a finer and clearer, can not be too deep and blowing a small amount of gas, acrylic engraving need to pay attention to is the resolution of the settings, if the output of the BMP format, the resolution is generally to be in the 600dpi or more, at this time the speed of 8-18 m / min, light intensity of 20%-30%, sweeping off the blowing to make the bottom smoother.
Thin material cutting (2-10mm) 5 mm below the plexiglass with 50mm focusing lens, cutting speed is generally 0.35-0.8 m / min, light intensity of 45-65%, 5-10mm plexiglass is generally used in 63.5 mm focusing lens, cutting speed of 0.15-0.3 m / min, light intensity of 50-75%, large-area engraving machine. Carry out carving if there is a more serious **** vibration (vibration), will also cause the accuracy of the engraving machine greatly reduced, so cutting plexiglass models of the width try not to exceed 1 meter, there is plexiglass engraving character image process produces some white powder, thus feeling more clear, if the carving to be wiped with water to appear more fuzzy. To look like the specific effect and which processing. Glass (or mirror) carving.
For some real glass carving, some customers carve the effect of sanding on the glass, but the sharp and thin places will be broken, so the speed and light intensity are very high requirements. General speed in 10 meters / min, light intensity in 35%. Mirror engraving generally use metal marking machine, the bottom is more delicate and smooth.
