3Dtulostaminen

3Dtulostaminen, also known as additive manufacturing, is a process of creating three-dimensional objects layer by layer from a digital model. This technology utilizes various materials, including plastics, metals, ceramics, and composites, to fabricate intricate designs that are often difficult or impossible to produce with traditional manufacturing methods. The fundamental principle involves a digital file, typically a CAD model, which is then sliced into thin horizontal layers by specialized software. A 3D printer then follows these instructions, depositing or solidifying material according to each layer's shape, gradually building up the object from the bottom.

There are several common 3Dtulostaminen technologies. Fused deposition modeling (FDM) is one of the most widespread, where thermoplastic filament is melted and extruded through a nozzle. Stereolithography (SLA) uses a UV laser to cure liquid photopolymer resin layer by layer. Selective laser sintering (SLS) employs a laser to fuse powdered material. These diverse methods allow for a wide range of applications across industries such as healthcare, aerospace, automotive, consumer goods, and education. 3Dtulostaminen enables rapid prototyping, customized production, on-demand manufacturing, and the creation of complex geometries, revolutionizing product development and manufacturing processes.
