Easy Guide to 3D Printing and Its Technologies

3d Printing ExamplesEvery year, technology companies are introducing new printing technologies for the manufacturing industry. In recent years, 3D printing has become very popular. The reason of its hype is the promising future of this technology that can transform manufacturing. With such options now, people can completely find a new way to create an item. In short, this technology does have the capacity to produce objects and fabricate them without using the traditional engineering skills. Imagine creating a replica of a product in minutes with one of the best 3D printers. Unlike the time taken in the traditional manufacturing process, 3D printing technologies can make the task easier and in lesser time. As a result, the industries can benefit from saving a lot of time by not engaging in traditional manufacturing processes.

3D Printing Technologies:

3D printing involves a number of technologies. Unlike the traditional printing technology, this process doesn’t include only a single technology of using inkject and printing cartridges. For all those tech savvy persons, 3D technologies make use of a combined process of additive manufacturing and software usage. The techniques used in the process use a material instead ink to create a 3D replica of the product. Of course, the process uses a block of material and gives it a shape to create the desired object. Here are some of the technologies used in 3D printing and modeling.


Fused Depositional Modeling is the most popular and first technique used in the 3D printing method. Users can either follow the FDM or FFM technology as per their choice. In case of the latter, the manufacturer can avoid trademarked terms while manufacturing the 3D model. The process starts with the extruding of the used material’s filament. As soon as the heating process is done, the heated material is squeezed through the nozzle of the pattern to give an outline to the material. The nozzle in fact moves over the surface of the pattern to fill the outline with the molten material in order to create the desired shape of the material.


Unlike the usage of molten heated filament in the above technique, the SLA technique makes use of polymer materials. The Stereolithography technology in SLA primarily relies on using photo-polymers, photo-sensitive resins, and materials that can change their shape by solidification with the exposure to UV light. The plus point is that manufacturers can use the UV light beam to harden the desired parts in the model to create the end product. During the process, a thin liquid is also poured over the hardened 3D structure to give the material the desired shape.


In this case, the 3D printers use a high power laser beam to create the 3D shape of the material by sintering the liquid or powdered material together. This is one of the latest technologies in 3D printing, which uses the extremely high resolution and strong laser beams on tough grade plastics.
