Technologies 3D printers is an additive process that builds objects one layer at a time from the bottom up. The right technology depends on the materials, aesthetics, mechanical properties and performance you require. Learn about the technologies available from Stratasys and Stratasys Direct Manufacturing.
Stratasys develops and manufactures two of the most versatile and widely used 3D printing technologies available today.
FDM creates parts layer-by-layer with engineering-grade thermoplastics. FDM is often used to build complex geometries and functional parts, including prototypes, low-volume production pieces, manufacturing aids, and jigs and fixtures.
PolyJet is a 3D printing process that jets and cures thin layers of liquid photopolymer with UV energy. It is capable of printing in 16-micron layers and in multiple durometers and many colors for multi-material parts. PolyJet is an excellent option for realistic, high-resolution models and prototypes, short-run injection molds and master patterns for urethane casting.
Stereolithography (also known as SL or SLA) builds parts layer-by-layer using a UV laser to solidify liquid photopolymer resins. It is commonly used to produce concept models, master patterns, large prototypes and investment casting patterns.
Laser Sintering (also known as Selective Laser Sintering, SLS or LS) uses a CO2 laser to heat and fuse durable thermoplastic powder to build versatile parts with high elongation at break. LS production parts and prototypes provide lightweight, heat and chemical resistant solutions.
Direct Metal Laser Sintering (DMLS) fuses powdered metal and alloy materials with a high-wattage laser to produce robust, metal parts. DMLS produces fully realized metal parts, including tools and production parts for a variety of industries.
