Design of three dimensional printing process

Design of three dimensional printing process

Three dimensional design
Design of three dimensional printing process: through computer modeling software modeling, model and then into “partitions” section of layer-by-layer, namely slice, to guide the printer printed layer by layer.
Design collaboration between the software and the printer’s standard file format is STL file format. An STL file using triangles to approximate the surface. Smaller triangles generated by its higher resolution. PLY is a three dimensional file produced by scanning scanner to generate VRML WRL file or input file is often used as a full-color print.

Epson R1800 Printer by reading the cross-section of the information in the file, use liquid, powder or tablet-like material these sections printed layer by layer, then sections of each layer in a variety of ways to glue together in order to create a single entity. Features of this technology is that it can produce almost any shape of goods.
Printer prints section of thickness (z direction) and flat direction that is x-y resolution in DPI (pixels per inch) or microns to calculate. Average thickness of 100 microns, or 0.1 mm, there are some printers such as the ObjetConnex series are three-dimensional Systems’ ProJet series can print out 16-Micron thin layer. gdPlane with laser printer you can print out a similar resolution. Print “ink droplet” is usually 50 to 100 microns in diameter. Using traditional methods to produce a model usually takes a few hours to several days, determined in accordance with the size and complexity of the model. While using three dimensional printing technology can be reduced to a few hours, of course, is determined by the printer’s properties, and depending on the size and complexity of the model.
Traditional manufacturing techniques such as injection molding method with low cost of producing polymer products, and three dimensional printing technology can be faster, more flexible and lower-cost way to produce a relatively small number of products. A desktop printer can meet the designer or concept development team created a model needs.

Printer resolution is sufficient for most applications (on a curved surface may be rough, like on the image as a saw), to obtain higher resolution can be as follows: first use current printers play a slightly larger objects, a little surface polishing to get smooth surfaces “high resolution” article.
Some techniques can be printed using a variety of materials. Some technology in the printing process can also be used to support, upside down, for example,to print out some objects needed to easily remove things (such as soluble things) as support.
