What Is 3D Printing?
Three-dimensional printing is a process of producing objects by adding materials in layers that correspond to continuous sections of a three-dimensional model. It can work on almost anything - from concrete to living tissue. Three-dimensional printing has been used in a variety of fields including manufacturing, medical, industrial and sociocultural. It can create and complete complex shapes or geometries in situations where hand building or industrial manufacturing is currently not possible
What To Buy A 3D Printer For?
- To create prototypes for your own designs or inventions
- To make custom parts or accessories for your hobbies or projects
- To print models, miniatures, toys, or art for fun or education or engineering testing
- To explore new possibilities of design and fabrication with different materials and technologies
Overall, a 3D printer can help you manufacture items of various shapes and sizes, thereby improving creativity, innovation, and production efficiency.
What Are The 3D Printing Processes?
Common 3D printing processes include:
Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF): This process involves melting and extruding thermoplastic material through a nozzle to build the object layer by layer.
Stereolithography (SLA): This process uses a laser to solidify liquid resin into a solid object, layer by layer.
Selective Laser Sintering (SLS): This process involves using a laser to fuse powdered material, such as nylon, into a solid object.
Digital Light Processing (DLP): Similar to SLA, DLP uses a projector to flash light onto a liquid resin, solidifying it into a solid object layer by layer.
Advantages and disadvantages of FDM, SLA, DLP, SLS
FDM (Fused Deposition Molding) technology is a process of heating and extruding thermoplastic filaments and stacking them in layers to form a model on a printing plate. the advantages of FDM technology are simple operation, low maintenance, wide variety of materials, rich colors, non-toxic and non-hazardous, suitable for printing large size, low cost models. the disadvantages of FDM technology are low accuracy and surface smoothness, slow molding speed and easy nozzle clogging.
SLA (three-dimensional light curing) technology is a process in which a UV laser beam outlines the cross-sectional shape of an object on the surface of a liquid photosensitive resin, causing the resin to cure and bond together layer by layer to form a model. and cleaning resin.
DLP (Digital Light Processing) technology is the process of projecting a cross-sectional image of an object onto the surface of a liquid photosensitive resin through a projector, causing the resin to cure and bond together layer by layer to form a model. structure and cleaning resin.
SLS (Selective Laser Sintering) technology is a process in which a laser beam scans the cross-sectional profile of an object over a layer of powder material, causing the powder to melt or sinter and bond together to form a model. the advantages of SLS technology are that it does not require a support structure and can construct complex and intricate geometries with a high degree of design freedom. the disadvantages of SLS technology are that the equipment is more expensive and is mainly used for production applications in the industrial sector.
