The utility model principle is as follows: first by microcomputer modelling software modeling, if you have ready-made model also passable, such as animal model, personage or micro building etc.Then cut into slices by slic 3r, by the data obtained by data line transfer on controller, the operation principle of 3D printer is substantially the same with conventional printer, is all made up of frameworks such as Control Component, mechanical component, printhead, consumptive material and media, and it is the same for printing principle.3D printer mainly devises a complete three-dimensional stereo model before printing on computers, and then prints out.
Three dimensional design:
The design process of 3 D-printing is first by microcomputer modelling software modeling, then the threedimensional model " subregion " built up is become cross section successively, namely cuts into slices, thus instructs printer successively to print.The Standard File Format cooperated between design software and printer is stl file form.A stl file uses triangular facet to come the surface of approximate simulation object.The less surface resolution that it generates of triangular facet is higher.
Print procedure:
These cross sections, by the cross sectional information in file reading, are printed with the material of wire diameter 1.75mm, then are glued together in every way by each layer cross section thus produce an entity by printer layer by layer.The feature of this technology is that it almost can produce the article of any shape.The thickness (i.e. Z-direction) in the cross section that printer is got and the resolution ratio in in-plane and X-Y direction are with dpi(pixel per inch) or micron calculate.General thickness is 200 microns, namely 0.2 millimeter, also has part printer such as Objet Connex series to also have D S ystems'ProJet series can print 16 microns of thin one decks.In-plane then can print with the close resolution ratio of laser printer." ink droplet " that print typically have a diameter from 50 to 100 microns.Producing a model by conventional method needs a few hours to a couple of days usually, determines according to the size of model and complexity.Can be then several hours by time shorten by the technology of 3 D-printing, it is determined by the performance of printer and the size of model and complexity certainly.Traditional manufacturing technology such as injection moulding can manufacture polymeric articles in a large number with lower cost, and three-dimensional printing technology then can with faster, the product that way production quantity that is more flexible and more low cost is relatively less.The three-dimensional printer of a Desktop Dimensions just can meet the needs of designer or concept development group modeling.
