Several 3D printing technologies cater to different needs, materials, and applications. Here are a few popular ones:
Fused Deposition Modeling (FDM):
Process: FDM printers melt and extrude thermoplastic filaments, which are deposited layer by layer.
Materials: PLA, ABS, PETG, and other thermoplastics.
Applications: Prototyping, hobbyist projects, and functional parts.
Stereolithography (SLA):
Process: SLA printers use a laser to cure liquid resin into solid layers.
Materials: Photopolymer resins.
Applications: High-resolution prototypes, detailed models, and dental applications.
Selective Laser Sintering (SLS):
Process: SLS uses a laser to sinter powdered materials, fusing them into solid structures.
Materials: Nylon, glass-filled polymers, and metal powders.
Applications: Functional prototypes, complex geometries, and small-batch production.
Digital Light Processing (DLP):
Process: Similar to SLA but uses a digital light projector to cure resin.
Materials: Photopolymer resins.
Applications: High-detail models and rapid prototyping.
