Perfect Options for the 3D Printing and the best WaysOn November 10, 2019 by Marshall Appelgren
3D printing is today one of the pillars of the fourth industrial revolution and the types of 3D printing created are increasingly innovative. The technology that makes a factory fit your workbench while looking new, has been around for over 30 years. During this time several types were created and improved, and several applications that can benefit you were thought and structured.

Cast Filament Fabrication (FDM or FFF)
Among the types of 3D printing, it is the most used technique, because its cost is not so high, but in compensation does not allow manufacturing with so many details. This technique consists of heating filaments of plastic material, usually PLA or ABS, to a semi-solid state and depositing them through the extruder nozzle. By moving it on the X, Y, Z axes, the object to be obtained is layer by layer.
The main advantage of this type of manufacture over other types is the price of the material and is easier to store and use. Another advantage is its ease of use, having much more material to study besides a wide range of printers on the market, with the most varied prices, allowing from small entrepreneurs to large companies to have access to this technology.
3d printing types
Another point to be made is that the FDM technique does not require much post-impression treatment, but is usually required for the removal of the supports, when existing, which can be done mechanically or chemically. Its disadvantages are the need for support depending on part geometry and lower print finish quality compared to other methods.
Stereo lithography (SLA and DLP)
The quality of the piece produced by this technique is remarkable. A method developed by Chuck Hull is the oldest technique among the types of 3D printing, being used to this day. Refers to the use of a laser and a reservoir with liquid resin when the resin is struck by the laser at the contour relative to the shape of the object, this part solidifies and sticks to the bottom layer. Then the support platform rises or falls, depending on the printer, a fraction of a millimeter in the tank, allowing the liquid resin to settle where the last layer of the solid was and allowing the laser process to resume until ask to be completed.
Typically, this 3D printing technique needs to undergo both chemical and mechanical post-press treatment to remove any unwanted debris. Its main advantage is the possibility of manufacturing parts with a high degree of complexity and detail, is widely used in dentistry and jewelry. It has a much higher production cost than the FDM technique.
Selective Laser Sintering (SLS)
The main advantage of this method, among the 3D printing types, is that it does not need supports to support the model during its manufacture, avoiding some post-printing treatments and allows to print high complexity parts with excellent finishing. This technique makes it possible to produce parts with a relatively wide range of materials, such as nylon, carbon fiber nylon. It consists of a laser (CO2) that fuses small particles of powder material, thus forming each of the layers of the object. Dust that is not struck by the laser remains in its natural form and thus serves as its support.
