Manufacturing Using Fused Deposition (FDM)
The extruded molten polymer filaments in this technology are then solidified into filaments of hundreds of microns in an external low-temperature environment after being fed into the nozzle, heated, and melting in the nozzle. The melt deposition is done at a fixed pace in accordance with the planned trajectory of each layer of the part to create a 3D entity. A
The appearance of stereolithography (SLA)
SLA has a wide range of applications, and photosensitive resin is the substance used. Using a laser spot as the print head. The laser spot can quickly move in the resin to print a line and then solidify in the order from line to surface to complete one layer. The lifting platform then moves the height of one layer in the vertical direction and then solidifies another layer so that the desired result is achieved.
Choosen Laser Sintering (SLS)
Powder materials like metal and nylon powder are among those utilized. Sintering forms the powder into a tightly bonded whole that is subsequently covered layer by layer under laser scanning to complete the formation process.
Processing of Digital Light (DLP)
The liquid photopolymer is cured using a high-resolution digital light processor (DLP) projector. The DLP chip then projects a cross-sectional picture of the printed layer onto the resin, hardening the exposed material. All points in each layer are simultaneously cured, allowing for faster layer printing while the platform gently ascends vertically out of the resin vat.
(MJP)
MJP technology is to print a thin layer of liquid plastic that can be cured by UV light on a flat platform. Additionally, utilize a waxy substance as a support during printing. When a layer is finished being cured under UV light, the modeling table falls to create another layer, and so on until the entire part has been printed.
