3D Printing Service Print Process
- Sep 04, 2017 -

3D printing service is a rapid prototyping technology, it is a digital model based on the file, the use of powdered metal or plastic and other adhesive materials, through the way of layer by layer to build the object technology.

3D printing is usually done using a digital technology material printer. Often in the mold manufacturing, industrial design and other fields are used to manufacture the model, after the gradual use of some products for the direct manufacture, has been used to print this technology from the parts. The technology is used in jewelry, footwear, industrial design, construction, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.

Ordinary printers used in daily life can print computer-designed flat items, and the so-called 3D printer and ordinary printer works basically the same, but the printing material is somewhat different, ordinary printer printing material is ink and paper, and the 3D printer with metal , Ceramic, plastic, sand and other different "print material" is a real raw material, the printer and computer connection, through computer control can "print material" layer together, and finally the computer blueprint into In kind. In layman's terms, a 3D printer is a device that can "print" out a real 3D object, such as printing a robot, printing a toy car, printing various models, and even food. The reason why the popular call "printer" is a reference to the general principle of the printer, because the process of hierarchical processing and inkjet printing is very similar. This printing technology is called 3D stereoscopic printing technology.

There are many different technologies for 3D printing. They differ in the way they are available and build parts with different layers. 3D printing commonly used materials are nylon glass fiber, durable nylon materials, gypsum materials, aluminum materials, titanium alloy, stainless steel, silver, gold, rubber

Print process

Three-dimensional printing design process is: first through the computer modeling software modeling, and then build the three-dimensional model "partition" into a layer by layer, that is, slices, to guide the printer layer by layer printing.

The standard file format for collaboration between the design software and the printer is the STL file format. An STL file uses a triangular face to approximate the surface of an object. The smaller the triangular surface, the higher the resulting surface resolution. PLY is a scanner that generates 3D files by scanning, and its generated VRML or WRL files are often used as input files for full color printing

Slice processing

The printer prints the sections in layers by liquid, powdery or sheet-like materials by reading the cross-section information in the document, and then laminating the sections in a variety of ways to create an entity. This technique is characterized by its ability to create almost any shape of the article.

The thickness of the cross section of the printer (ie, the Z direction) and the plane direction, that is, the resolution in the X-Y direction, is calculated in dpi (pixels per inch) or micron. The general thickness of 100 microns, that is 0.1 mm, there are some printers such as ObjetConnex series and three-dimensional Systems' ProJet series can print a thin layer of 16 microns. And the plane direction can be printed with the laser printer similar to the resolution. The printed "ink droplets" are usually 50 to 100 microns in diameter. Creating a model in a traditional way usually takes several hours to several days, depending on the size of the model and the complexity. And three-dimensional printing technology can be shortened to a few hours, of course, it is by the printer's performance and model size and complexity of the.

Traditional manufacturing techniques such as injection molding can produce polymer products at a low cost, while 3D printing technology can produce relatively small quantities of products with faster, more resilient and less costly methods. A desktop size of the three-dimensional printer can meet the needs of designers or concept development team manufacturing model.

Complete the print

The resolution of a 3D printer is sufficient for most applications (which may be rough on a curved surface, like a sawtooth on an image). To get a higher resolution item can be done by using the current three-dimensional printer Playing a slightly larger object, and then slightly through the surface polished to get the surface smooth "high-resolution" items.

Some techniques can be printed at the same time using a variety of materials. Some techniques use the support during printing, such as the need to use something that is easy to remove (such as soluble things) as a support when printing something that has an upside-down.
