Three-dimensional printing
Three dimensional printing is the process of printing three dimensional objects out of successive layers of super thin material; typically a thermoplastic material. Three dimensional printing is a popular way for many professionals to turn digitals concepts into models, prototypes, and ready to use products. Such products may include jewelry and small toys. Additionally, large production machines have industrial applications which can include component manufacturing and rapid prototyping.
Three dimensional printers can range in size from small personal models to larger professional models the size of refrigerators. The process to print on these printers is a fairly straightforward and simple process. The printer’s auto-loading containers are filled with the material which the object will be built from. Then, the operator would level the printing bed in the machine and adjusts the nozzle heads to the optimum height. When the machine is commanded to print, the nozzle continually moves in multiple directions and dispenses the heated material in successive layers which as a result from the desired object.
The movements of the printer are controlled by the digital design file. This file is typically created with the use of Computer Assisted Design software, also known as CAD. The file is then converted into printer code and fed to the printer via a memory card or attached computer.
There are a few disadvantages to using three dimensional printing software and printers. These include: limitations in size, imperfections as well as cost. Due to the strength of the materials used, three dimensional printers are unable to create objects which are large in size. In addition to the low strength of the material, many objects which are created through three dimensional printing tend to possess an unfinished look and possess a ribbed or rough surface finish. Lastly, the cost of three dimensional printing tends to be considered fairly expensive. The average cost of a three dimensional printer van range anywhere from $5,000 to $50,000 depending on the type of model needed. This is an expensive investment which doesn’t even include the price of accessories and materials.
