Extrusion-Based 3D Printer
An Extrusion-Based 3D Printer, commonly referred to as a Fused Deposition Modeling (FDM) printer, is an additive manufacturing device that builds three-dimensional objects layer by layer by extruding thermoplastic filaments. The filament is fed through a heated nozzle that melts the material and deposits it on a build platform according to a digital design. As each layer cools and solidifies, it bonds to the previous one, forming a complete object.
This form of 3D printing is one of the most accessible and cost-effective technologies, making it a popular choice in educational settings, prototyping, and hobbyist applications. The ability to use materials such as PLA, ABS, TPU, and PETG allows for flexibility in part strength, durability, and thermal resistance. Some printers also support composite filaments reinforced with carbon fiber, wood, or metal particles.
Beyond rapid prototyping, extrusion-based 3D printing is expanding into customized healthcare (like prosthetics), architecture (concept models), and even food and biomedical applications (bioprinting with paste-like materials). Advances in multi-material and multi-nozzle setups allow for complex, functional components to be printed in a single process. Integration with slicing software, cloud-based platforms, and AI-based defect detection further enhances the usability and scope of these machines.
