Polymeerilangoista

Polymeerilangoista, also known as polymer filaments, are the raw materials used in 3D printing by fused deposition modeling (FDM) or fused filament fabrication (FFF) technologies. These filaments are essentially strands of thermoplastic material, typically wound onto spools, that are melted and extruded layer by layer to build a three-dimensional object. The diameter of the filament is crucial for the printing process, with common sizes being 1.75 mm and 2.85 mm (often referred to as 3 mm).

The variety of polymers available for 3D printing is extensive, each offering different properties suitable for specific applications. Common examples include polylactic acid (PLA), a biodegradable and easy-to-print option derived from renewable resources, and acrylonitrile butadiene styrene (ABS), known for its strength and durability but requiring higher printing temperatures and good ventilation due to fumes. Other popular filaments include PETG, which combines the ease of PLA with the strength of ABS, and nylon, valued for its flexibility and abrasion resistance. Specialty filaments exist with additives like carbon fiber, wood particles, or metal powders to achieve unique aesthetic or mechanical characteristics. The choice of polymerilanka directly influences the strength, flexibility, heat resistance, and overall appearance of the final 3D printed part.
