Selective Laser Sintering

SLS

Selective laser sintering is a powder-based 3D printing technology that uses a laser to fuse material layers into a final part. After the laser traces a cross-section of the CAD design(s) onto a material layer, the build platform lowers and another layer is fused on top. The build platform continues to lower until every layer is built and the part is complete.

Aarya Industries’ SLS materials include a range of optimized nylon and elastomeric powders.

Selective laser sintering is an additive manufacturing technology that uses a high power laser to sinter small particles of polymer powder into a solid structure based on a 3D model.
SLS is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts.
It is proving to be increasingly popular with clients, as its potential applications widen. Many clients now use this additive manufacturing process for low volume production of components and as an alternative to traditional production methods which involve the need for tooling.

Advantages of "Selective laser sintering"

A distinct advantage of the SLS process is that because it is fully self-supporting, it allows for parts to be built within other parts in a process called nesting – with highly complex geometry that simply could not be constructed any other way.
Parts possess high strength and stiffness
Good chemical resistance
Various finishing possibilities (e.g., metallization, stove enameling, vibratory grinding, tub coloring, bonding, powder, coating, flocking)
Bio compatible according to EN ISO 10993-1 and USP/level VI/121 °C
Complex parts with interior components, channels, can be built without trapping the material inside and altering the surface from support removal.
Complex parts with interior components, channels, can be built without trapping the material inside and altering the surface from support removal.
Vast variety of materials and characteristics of Strength, durability, and functionality, SLS offers Nylon based materials as a solution depending on the application.
Due to the excellent mechanical properties the material is often used to substitute typical injection molding plastics.

FAQ's on "Selective laser sintering"

What is Selective Laser Sintering used for ?

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.

How does Selective Laser Sintering works ?

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.

What is used as base material in Selective Laser Sintering ?

We offer SLS prototype parts using PA 2200 (base PA12) material. PA2200 is a fine, white powder with a well-balanced property profile that is ideal for a wide variety of applications.

What are the parameters for Selective Laser Sintering process ?

The main laser parameters include wavelength, power, scanning speed, hatch distance, scan pattern, vector length [12], ratio of length to width [25], scan angle [25], beam spatial distribution [26], beam spot size [27], point overlapping [28], and continuous or pulsed laser operation.

What is the resolution of Selective Laser Sintering ?

Laser sintering <5 μm features with high throughput. The μ-SLS system employs an optical system for printing the desired patterns onto the substrate with a feature resolution better than 5 μm and a pixel resolution close to 1 μm.

Why SLS is considered ideal for complex geometries ?

SLS technology is ideal for creating highly complex parts since it does not require support structures, unlike SLA (stereolithography) and FDM (Fused Deposition Modelling). … Furthermore, with SLS technology, you can create parts and geometries that would otherwise be impossible with traditional manufacturing methods.

What is the role of unsintered powder in SLS ?

Selective laser sintering (SLS) is a powder-based fusion technology that uses a laser beam to locally sinter polymer powder to build parts layer by layer. … Unsintered powder remains in place to support subsequent layers eliminating the need for support structures.
