The laser sintering (LS) process uses a laser source to provide thermal energy and selectively fuse together particles of a powder material into complex three-dimensional shapes in a layer-by-layer strategy [52].
How does selective laser sintering works?
SLS 3D printing uses a high power laser to sinter small particles of polymer powder into a solid structure based on a 3D model. Printing: The powder is dispersed in a thin layer on top of a platform inside of the build chamber. This fuses the particles together mechanically to create one solid part.
How does SLS process work?
The SLS 3D printer uses a laser as a energy source which selectively melts powdered plastic material, fusing them together into a 3D printed part. Using 3D data from a CAD model, the laser melts the plastic material exactly at the predifined areas in the powderbed of the additive manufacturingadditive manufacturing3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties, requiring different temperatures to print. Filament is commonly available in the two standard diameters of 1.75 mm and 2.85 mm.https://en.wikipedia.org › wiki3D printing filament - Wikipedia system.
What are the advantages of laser sintering?
Selective Laser Sintering Advantages Best for producing strong, functional parts with complex geometries. High level of accuracy (though not as high as stereolithography). Doesn't require supports, saving printing and post-processing time.
What materials can be SLS printed?
A Brief History of SLS 3D Printing Their method has since been adapted to work with a range of materials, including plastics, metals, glass, ceramics, and various composite material powders.
What is SLS printing used for?
A SLS 3D printing service is used for both prototyping of functional polymer components and for small production runs. Its versatility makes SLS a great alternative to injection molding for low-production runs.
What materials can be processed with metal laser sintering or laser melting processes?
Some of the materials being used in this process can include Ni based super alloys, copper, aluminum, stainless steel, tool steel, cobalt chrome, titanium and tungsten. SLM is especially useful for producing tungsten parts because of the high melting point and high ductile-brittle transition temperature of this metal.
What are the disadvantages of selective laser sintering?
- Very expensive. The machines can often cost $250,000+, and the materials cost $50-60/kg.
- Cool-down time of 50% of print time can mean up to 12 hours of waiting. This leads to longer production time.
- Parts have a grainy surface without any post-processing.
What are the advantages and disadvantages of selective laser sintering?
S.No. SLS Advantages SLS Disadvantages
----- -------------------------- -----------------------------------------
4. Best for experimental use. Potential health hazards.
5. Very fast 3D printing. 3D prints are brittle in nature.
6. Robust 3D Printed parts. Post-Processing procedures are difficult.
7. High dimensional accuracy.
What are the advantages and disadvantages of stereolithography?
- It's quick.
- It's cheap.
- It aids prototyping.
- It's a multi-material process.
- It creates tools, quickly.
- High quality parts.
- Snap-together assemblies.
- Scaling is easy.
What are the disadvantages of stereolithography?
- Fragility: stereolithography uses equivalent materials which are resins.
- Expensive machines: if we had predicted the boom in 3D printing in the past few years, experts have neglected the cost of the machines and the difficulty of their operation.
Does SLS need support material?
Selective laser sintering does not require support structures because unsintered powder surrounds the parts during printing. SLS printing can produce previously impossible complex geometries, such as interlocking or moving parts, parts with interior components or channels, and other highly complex designs.
