3D printing, as all of you are aware of, is a kind of additive manufacturing technology that involves the creation of a three-dimensional object. The three-dimensional objects are created by laying down successive layers of materials.
The 3D printers are faster, affordable as well as easier to use. The very first thing to begin with here is creating a CAD sketch. The additive manufacturing device will read data from the CAD file and build a structure layer by layer from the printing materials. The printing materials may be anything ranging from plastic, powder filaments to a sheet of paper.
Here is an overview of the essential 3D printing technologies as well as printing materials that are presently in use on the industrial level.
Filament-Based 3D Printing
The home printers chiefly work with plastic filaments. The technology behind is referred to as the “Fused Filament Fabrication” (FFF).These printers use the following materials to print things.
·PLA (Poly Lactic Acid)
This is the easiest material to work with when you begin with 3D printing. This is an environment-friendly material that is safe to use since it is a biodegradable thermoplastic derived from renewable sources like sugarcanes and corn starch.
·ABS (Acrylonitrile Butadiene Styrene)
ABS is regarded as the second easiest material to function with when you begin working with 3D printing. Safe and strong, this is widely in use for things like Lego and car bumpers.
Powder-Based 3D Printing
This family of printers is not based on filament but on powder. Laser sintering is used for creating 3D prints in Alumide, Polyamide, Titanium, and Wood.
This is a strong as well as a flexible material that allows achieving a high level of detailing. The Polyamide objects are constructed using fine white granular powder.
This is a Polyamide-like material coming with a distinct sandy and granular look. The alumide objects are made using a blend of polyamide and gray aluminum powder.
Why do you think this is a great technology? This technology is well known because there is little need of a supporting structure. This allows complex designs as well as moving parts and interlinking.
Resin-Based 3D Printing
Resins are used as a material in 3D printing though the design freedom gets limited here owing to the necessity of supporting the objects in the course of the printing process. Here are a few examples of resins that can be made use of.
·High Detail Resin
The objects that are prepared of high detail resin are made of a photo polymeric liquid.
The objects made of printable resin come with a smooth surface and looks beautiful when printed.
The objects that are made of transparent resin are constructed of a hardened liquid. This material is strong, hard, stiff, water resistant and of course, transparent. Transparent resin is suitable for the models that require smooth, good and a quality surface.
How 3D Printing Works?
The process of 3D printing is divided into 3 main steps.
1.This is the preparation step that comes in right before printing when a 3D file of the object you want to print is designed. This file is possible to create using CAD software with a 3D scanner. You can also download it of an online marketplace. As soon as your 3D file is all set to be printed, you can move on to the next step.
2.This is the actual process of printing. You need to choose the material that will perfectly achieve the properties necessary for a given object. As already said, there are different types of materials in use for 3D printing. Most of these materials allow several finishing options that aid in achieving the precise design.
3.This step needs specific skills as well as materials. As soon as the object is first printed, it may not be possible to deliver till it is sanded, lacquered or painted.
The list of 3D printing processes and technologies continues to grow since 3D printing is changing continually. The 3D printing industry continues innovating the hardware as well as materials and processes for creating parts or objects. Depending upon aspects like budget, function or design, it is vital to choose the appropriate 3D printing process.
