If you believe that all 3D printers use filaments, and terms like Stereolithography, Laser Sintering, and PolyJet Printing cause you headaches, then this blog post is for you.
In this post, we’ll give you an overview of the essential 3D printing technologies and 3D printing materials that are currently used on an industrial level. If you are looking to customize 3D products for your business, then it would be best to get help from experts from a 3D modeling agency.
Filament-based 3D Printing
Home printers typically work with plastic filament. The technology behind this is often referred to as “Fused Filament Fabrication” (FFF).
In our 3D printing factory, we have more professional, industrial-grade machines: our filament printers use a technology called “Fused Deposition Modeling” (FDM).
In an FDM printer, a long plastic filament is fed by a spool to a nozzle where the material is liquefied and ‘drawn’ on the platform, where it immediately hardens again. The nozzle moves to place the material in the correct location to build your model up layer by layer. When a layer is drawn, the platform lowers by one layer thickness so the printer can start with the next layer. Sounds similar to a regular home printer?
Powder-based 3D Printing
The next big family of printers that we have is not based on filament but powder. Laser Sintering is used to create 3D prints in Polyamide, Alumide, and Polypropylene.
The interior of the printer is heated up to just below the melting point of the powder of your choice. The printer then spreads out an incredibly fine layer of this powder.
A laser beam heats the areas that need to be sintered together just above the melting point. And voila: the parts that were touched by the laser are now fused while the rest remain loose powder.
Earth is home to millions of species. Among the millions of species, there is a superior species called humans. We are humans! And it is kind of ironic that we are known as superior species since humans are solely responsible for harming and polluting the environment.
The world anthropoid population has a negative impact on the environment. The world overpopulation concern is not limited to harming the environment in a single or only one way.
There are multiple ways through which human overpopulation affects the environment. Some of them are discussed below-
We all know that humans need food in order to survive and for getting food humans are dependent on farming for a very long time. With the advancement of time and with the increasing population, demand for food has risen.
There were more mouths to feed than there was food and to overcome this difficulty, farmers with the support of the government started cutting the forest in order to increase their hold on land that was fit for farming. As a result of this practice, forests started to shrink at a great pace thereby damaging the environment and natural habitat of animals at the same time.
Due to population rising at leaps and bounds, it was becoming impossible for the superior species to build houses to live in, it was becoming hard for superior species to pass through the forest in order to travel from one place to another.
So they arrived at the conclusion of cutting down the forest altogether to build houses, roads and to increase farming capacity.
Population spurt has forced village people to move to the cities to make their ends meet. Sometimes what happens is that due to unemployment people resort to unconventional ways to earn money. A large population is the reason behind unemployment and unemployment is the reason behind the elevation in the crime rate.
