Description
Technical field
The invention belongs to 3D printing technique field, particularly relate to a kind of method that the 3D of employing printing technique carries out carcass making.
Background technology
The normal printer used in daily life can printing calculator design flat objects, and so-called 3D printer is substantially identical with normal printer operation principle, just some difference of printed material, the printed material of normal printer is ink and paper, and 3D printer is built with different " printed material " such as metal, pottery, plastics, sand, out and out raw material, after printer is connected with computer, " printed material " can be stacked up from level to level by conputer controlled, finally the blueprint on computer be become in kind.Generally, 3D printer is a kind of equipment that " can print " real 3D object, such as prints a robot, prints toy car, print various model, or even food etc.Why being generically called " printer " is the know-why that have references to normal printer because layering processing process and inkjet printing quite similar.This printing technique is called 3D three-dimensional printing technology.3D prints and there is many different technology.Their difference is in the mode of available material, and builds establishment parts with different layers.3D prints common used material nylon glass, durability nylon material, gypsum material, aluminum, titanium alloy, stainless steel, silver-plated, gold-plated, rubber type of material.Wherein SLA and photosensitive resin solidification 3D printing technique are one of technologies using comparatively ripe.SLA laser formation and stereolithography, this technology take photosensitive resin as raw material, the outer line laser of purple light under being controlled by computer is the pointwise of track liquid towards numerical value with the profile of predetermined part each point of layer cross section, successively scans, and makes the curing molding by the thin resin layer of scanning area generation photopolymerization reaction.The feature of SLA technology has higher precision and good surface quality, and raw-material utilization rate is recyclable close to 100% environmental protection, and shaping completeness, close to 100%, makes mathematical model visualize, reduces the cost of errors repair.It when without the need to preparing any mould, cutter and tooling fixture, can directly accept product design data, produces the exemplar of new product, mould or model fast.Therefore, applying of technology can shorten new product development cycle, reduction development cost, raising development quality greatly.It can manufacture complex-shaped (as hollow parts), meticulous part (as handicraft, jewellery etc.), make design, interchange and assess visualization more, the work such as new product designs, sample manufacture, market order, Operational preparation can be walked abreast carry out, raise the efficiency.The material that SLA selects is all different with other technique, and the material of most of technique all only has physical change, and SLA then needs chemical reaction, and therefore SLA needs selection to have the material of absorption and response speed faster to laser, ensures curing rate with this.
Large lacquer craftwork is China's traditional handicraft, and be a kind of process of surface treatment, its marrow is of long standing and well established, have light clean, easily wash, the ground such as the features such as body is light, heat insulation, corrosion resistant, have good security, Japan are still feeder with lacquerware.Lacquerware production process is complicated, and work consuming is consuming time, and lacquerware kind is various especially again, not only for ornament furnishings, and vessel, stationery and the art work, but also be applied to musical instrument, funeral apparatus etc.Lacquerware costly, is divided into carcass to make and surface lacquer process two parts.Wherein carcass complex manufacturing technology, have wooden tire, metal tire, tread flaking etc., cost is higher.When making carcass, wood tire uses comparatively extensive, until today is still used, it makes without the need to mould, manual Che system (moulding is confined to circle), the light and handy feature having lacquerware to pursue, have customization basis, but bulk article uniformity is poor, and there is the problems such as material cracks in wooden tire, unstable.Metal tire manufacture craft is comparatively complicated, and body weight, needs die casting, die cost and errors repair cost higher, homogeneity of product is better, customizes difficulty, and later stage surface lacquer process polishing is more difficult.Tread flaking, folder Ramie tire, Ramie and burlap make the inner tube of a tyre with wood or mud, then with some layers of paper such as the burlaps of ash of painting, dry real after, remove the inner tube of a tyre, finally on burlap shell, coat with lacquer paint.See the Warring states at the beginning of this light and handy carcass, the Qin Dynasty is still rare, and Two Hans mid-terms is later popular gradually, and become the most universal method of making base, it needs the inner tube of a tyre, outer placenta, has high cost, high artificial drawback equally.
Surface lacquer process is divided into priming paint, table Ramie, dust, coats with lacquer the steps such as paint, and its operation and content make according to concrete lacquerware and require adjustment.Wherein priming paint commonly uses natural raw lacquer namely from the milky mucilage binding liquid that lacquer tree is tapped, once transfer brown to after ingress of air, the economic worth of raw lacquer is very high, there is corrosion resistant, wear-resisting, acidproof, solvent resistant, heat-resisting, water proof and good insulating, be rich in the characteristics such as gloss, the high-quality coating of military project, industrial equipment, agricultural machinery, capital construction, artifacts and civilian furniture etc., priming paint is carcass and intermediate medium, the excessively coating of coating with lacquer paint, finish paint and carcass are better binded, improves stability.Table Ramie is namely at carcass surface paper burlap, and to ensure the stability of carcass, strengthen intensity, this step can consider whether use according to the selection of carcass material.Dust the ash material of exquisiteness is scraped to invest carcass or burlap surface, polishing, beats and smear, break, and make surperficial thickness even, mosaic technology, except bottom ash, also wants last thin grey; Deashing, with sand paper or grinder buffing, reaches smooth, without ripple glaze; Scrape slurry, by thin ash material, grey base hole is struck off, find the place's repairing in time that comes off; Sand milling, with the fine grinding of thin waterproof abrasive paper, until surface smoothing is complete.Coat with lacquer paint, with polished lacquer or cashew nut paint, brush (or spraying, showering) on the grey base made (first up and then down during brushing, then brush successively from left to right) equably, lower basement room dries in the shade.After doing solid work, by sand paper sand milling.Then carry out as required coating with lacquer painting for the second time, for the third time ... method is identical, and lacquerware process of surface treatment is a lot of, element paints, pick paint, embossed lacquer, inlay mother-of-pearl inlay, money coloured silk etc., presents the diversity of technique, makes according to product requirement again.
In large lacquer craftwork production process, the integrity degree of carcass and smoothness very important to whole lacquerware quality, decide man-hour and cost.Even to this day, though large lacquer craftwork heritage and development continues into the present, but still the high cost of carcass making, high artificial technique drawback cannot be reformed.
