SLS 3D Printer Cost
Selective Laser Sintering (SLS) 3D printers represent a significant advancement in additive manufacturing, offering the ability to create complex and durable parts. When considering the cost of SLS 3D printers, it’s important to understand that prices can vary widely based on factors such as size, speed, precision, and the brand.
Entry-Level Desktop SLS 3D Printers
For those new to SLS printing or with limited budgets, desktop SLS 3D printers are accessible. Prices for these machines start at around $6,000, making them suitable for small businesses, educational institutions, and hobbyists. These printers typically offer a smaller build volume and may have slower print speeds but still maintain a high level of detail and part strength.
Mid-Range Desktop SLS 3D Printers
Mid-range models, like the Sinterit Lisa, are priced at approximately $13,990. They strike a balance between affordability and professional capabilities, and they are suitable for design studios and engineers who require higher precision and a larger build volume.
Professional Desktop SLS 3D Printers
Professional-grade printers, such as the Sinterit Lisa Pro, offer enhanced features like larger build volumes and improved precision. These models are priced at about $17,990, catering to professionals who need production-quality in a desktop package.
Industrial SLS 3D Printers
At the top end of the market are industrial SLS 3D printers. These systems offer the largest build volumes, fastest print speeds, and a wide range of material options. They are designed for high-volume production and can cost upwards of $100,000, depending on the specifications and capabilities required.
How does SLS 3D printer work?
Selective Laser Sintering (SLS) builds parts by fusing powdered material layer by layer with a laser:
1. Preparing the Powder Bed: The process starts with a thin layer of powder material—typically nylon or other thermoplastics—spread evenly across the build platform.
2. Sintering with Laser: A high-powered laser selectively fuses the powder particles in accordance with the cross-sectional area of the design. The laser’s path is dictated by a digital file, ensuring precise adherence to the model’s geometry.
3. Layering: After a layer is sintered, the build platform lowers, usually by about 0.1 mm, and a new layer of powder is applied on top.
4. Repeating the Process: The sintering and layering steps are repeated, building the object up one layer at a time.
5. Cooling and Extraction: Once printing is complete, the build chamber is left to cool, after which the finished parts are extracted from the loose powder.
6. Post-Processing: Excess powder is removed, often with compressed air, and parts may undergo additional post-processing like vibratory smoothing or dyeing to improve their surface finishes and properties.
