Additive manufacturing or AM or commonly known as 3D printing, points out to the processes to synthesize a three dimensioned object with successive layers that end up an object with the control of a computer. Considered as the signal of the third industrial revolution, 3d printing succeeded the production line assembly in the manufacturing industry. Another simple definition of 3d printing or additive manufacturing, is that it is a process that makes three dimensional solid objects with the use of a digital file.

With the use of additive process, wherein several layers of material are laid down until a 3D printed object is created. Layers of thinly sliced horizontal cross section can be seen until the formation of the desired object. Find out for further details on camworks right here.
In order to create the object, you can start your 3D printing process by making a virtual design of the item you like to develop. With the aid of a 3D scanner that makes a 3D digital copy of the item, a virtual design is formed through this computer aided design file. Different technologies are used by 3D scanners such as time of flight, structured or modulated light, volumetric scanning and others. Recently, there are famous companies that enabled their hardware to perform 3D scanning. It is envisioned that future models of smart phones could have integrated 3D scanners. Nowadays, there are expensive professional 3D scanners to cheap DIY scanners that anybody can perform at home.
There are also different forms of 3D modelling software. One form is the industrial grade software with a license that costs thousands every year. Another example of the form is a free open source software that accompanies a tutorial video for beginners
Those who would like to start with 3D printing have to ask themselves whether it is the hardware that he or she is interested, or is it the creation of the object. There are available 3D printers for beginners that will help one decide either a pre-assembled 3D printer or a 3D printer kit. Given that you are on a tight financial condition but wants to learn3D printing, it is suggested that you start with a cheap 3D printer kits.
Know that not all 3D printers use similar technology. Considered as the most common technologies are the selective laser sintering or SLS and the fused deposition modelling or FDM. Another common technology is the stereolithography or SLA.
Rapid prototyping, architectural scale models, healthcare and entertainment are some areas where 3D applications can be further used. Paleontology, archaeology, forensic pathology and in crime scenes can make use of 3D printing for the jobs on hand.
