FDM (Fused Deposition Modeling) is a 3D printing technology that works on the principle of melting various thermoplastics (e.g. ABS or PLA plastic) and applying them to a precisely defined location for gradual creation of an object layer by layer. The basis for FDM printing is a high-quality 3D model, which is divided into thin layers with the help of software called SLICER. The printer follows these layers and prints the material along predetermined paths. The main advantages of FDM printing are low costs, ease of use and a wide range of available material types.
SLS (Selective Laser Sintering) is a method of 3D printing where a laser beam selectively sinters (bakes) thin layers of powdered material, usually plastic or metal. The process takes place layer by layer, with the laser combining particles into a solid object with high precision. SLS enables the production of complex and durable models without the need for support structures. It is used in industry for prototypes, functional parts and low-series products.
SLA (Stereolithography) is currently considered one of the most accurate methods of 3D printing. The technology works on the principle of curing photopolymer resin with UV light. The resin is then poured into a reservoir, where a high-resolution screen illuminates the resin in areas where it needs to harden. The process is repeated layer by layer, with the platform on which the resin is hardened moving out of the reservoir. The advantages of SLA printing include high accuracy, smooth surfaces and the ability to print complex geometries. The cost of materials is higher, and the printing time is longer compared to other 3D printing methods.
DLP (Digital Light Processing) print is a 3D printing technology where liquid resin is hardened with the use of a digital projector, which projects light patterns onto the surface of the resin. The light quickly hardens the selected parts of the resin, layer by layer, until a complete 3D model is formed. DLP print enables very high resolution and smooth surfaces, making it popular for precise prototypes, dentistry, and jewelry. The process is fast and accurate.
