3D printing is an additive manufacturing process that creates a three-dimensional object from a digital model. The object is built up layer by layer, starting with the bottom layer. The technology has come a long way in a short amount of time and is now being used to create everything from medical implants to car parts.
But what is 3D printing, and how does it work?.
3D printing is the process of creating a three-dimensional object from a digital model.
To create a 3D print, you need a 3D printer, a 3D model, and some type of filament. The filament is the material that the object is printed with. There are a variety of filaments available, including plastic, metal, and wood.
The 3D model is created using a 3D modeling program. There are a number of different programs available, including SketchUp, Autodesk 3ds Max, and Blender.
Once you have a 3D model, you can print it using a 3D printer. 3D printers come in a variety of shapes and sizes, from small desktop printers to large industrial printers.
The print process starts with the 3D printer heating the filament to a temperature that is just below its melting point. The hot filament is then extruded through a nozzle, where it is deposited on the build platform in the shape of the first layer of the object.
The nozzle is then moved up, and the process is repeated for the next layer. The object is built up layer by layer, until it is complete.
3D printing is a great way to create a physical model of your 3D models. It's also a great way to create prototypes of objects that you plan to manufacture.
There are a number of different 3D printing technologies available, including Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS).
FDM is the most common 3D printing technology, and it is used to create the majority of 3D prints. FDM works by depositing melted plastic filament in layers to create the object.
SLA is a more expensive technology, but it produces higher quality prints. It works by curing a liquid resin with a laser to create the object.
SLS is a more expensive technology, but it produces the highest quality prints. It works by heating a bed of powder to a temperature just below its melting point. The powder is then fused together with a laser to create the object.
