Selective laser sintering is an additive manufacturing (AM) technology that uses a high power laser to sinter small particles of polymer powder into a solid structure based on a 3D model. SLS 3D printing has been a popular choice for engineers and manufacturers for decades.
Beside above, how does Selective Laser Sintering work?
Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Keeping this in consideration, how long is selective laser sintering?
Selective laser sintering (SLS) is an industrial 3D printing process that produces accurate – rapid prototypes and functional production parts in as fast as 1 day. Multiple nylon-based materials are available, which create highly durable final parts.
How much does an SLS machine cost?
But why choose SLS over other technologies?
| 3D Printer | Max. Build Volume (mm) | Market Price |
|---|---|---|
| Sintratec S2 | ⌀160 x 400 mm | From $30,000 |
| Sharebot SnowWhite 2 | 100 X 100 X 100 | From $40,000 |
| Wematter Gravity | 300 x 300 x 300 | From $120,000 |
| XYZprinting MfgPro230 xS | 230 x 230 x 230 | From $69,900 |
How much does selective laser sintering cost?
With a starting price of around $100,000 that goes well beyond that for the full solutions, traditional industrial SLS has been inaccessible for many businesses.
Is selective laser melting expensive?
SLM is a fantastic yet costly 3D printing technology. It is most useful for creating parts made of pure metals, as the higher temperatures can fully fuse powders together into dense parts. SLM parts are much stronger than most other metal 3D printed parts, making this technology coveted in high-end applications.
What are the advantages of SLS?
Benefits & Limitations of SLS
- SLS parts have good, isotropic mechanical properties, making them ideal for functional parts and prototypes.
- SLS requires no support, so designs with complex geometries can be easily produced.
- The manufacturing capabilities of SLS is excellent for small to medium batch production.
What is rapid prototyping technology?
Rapid prototyping is the fast fabrication of a physical part, model or assembly using 3D computer aided design (CAD). The creation of the part, model or assembly is usually completed using additive manufacturing, or more commonly known as 3D printing.
What is selective laser sintering used for?
SLS machines can print objects in a variety of materials, such as plastics, glass, ceramics and even metal (which is a related process known as direct metal laser sintering). This makes it a popular process for creating both prototypes as well as final products.
What is SLS prototyping?
Selective Laser Sintering (SLS) is a 3D Printing technology used for rapid prototyping and additive manufacturing of 3D parts with complex shapes and geometries. A wide of range of part sizes is possible with SLS, with a choice of finishing and turnaround options available to suit most requirements.
What is the difference between SLS and SLM?
In SLM, powdered material is melted, whereas in SLS the powder is heated below its melting point (sintering). When laser heats the powder material to below melting point, it forms solid by fusion. The working principle is almost same in both printing method.
What is the nozzle temperature required for PLA filament?
To find the optimal nozzle temperature we recommend starting with a temperature right in the middle of the manufacturer’s suggested settings. If the manufacturer recommends 190°C – 220°C, printing at 205°C is a good starting point. Based on the quality of the print we suggest adjusting ± 5°C at a time.
What material is used in selective laser sintering?
The most common material for selective laser sintering is nylon, a highly capable engineering thermoplastic for both functional prototyping and end-use production. Nylon is ideal for complex assemblies and durable parts with high environmental stability.
Which 3D printer works similar to a hot glue gun?
If you’ve seen a 3D printer in person before, chances are pretty good that it was an FDM printer. Functionally speaking, your average FDM machine works a lot like a hot glue gun that’s being operated by a robot. Solid material goes in one end, gets pushed through a hot nozzle, melts, and is deposited in thin layers.
