Are you looking for an additive technology that you can use to build parts with complex, organic geometries that are also durable? Whether you’re a designer or engineer, Selective Laser Sintering (SLS) offers you the freedom to create intricate, high-quality parts with unmatched precision.
Selective Laser Sintering (SLS) is an industrial 3D printing process that produces accurate prototypes and functional production parts in minimal time. Selective laser sintering 3D printing is ideal for producing prototypes that require strength. It consists of functional plastic parts with mechanical properties for prototyping or small series production. Selective Laser Sintering (SLS) is a 3D printing technology that combines tiny plastic powder particles (nylon and carbon fiber) with laser technology to produce solid objects. A variety of nylon-based materials and thermoplastic polyurethane (TPU) options are available to create highly durable final parts where heat resistance, chemical resistance, flexibility or dimensional stability are required. With SLS 3D printing, no support structures are required, multiple parts can be easily nested into a single build, and is an economical solution when large quantities of 3D printed parts are required. We offer the best SLS 3D printing services which have become the most popular printing technology in industries like consumer goods, factory tools, aerospace components and more. We will create your 3D printed part accurately from your original object and deliver it within the timeframe we promise. Let us serve you!
Laser sintering is a popular and versatile 3D printing technology thanks to its high precision, design freedom, and wide range of production-grade materials. Suitable for all stages of the production lifecycle, from prototyping to small series or custom manufacturing, laser-sintered parts need no support structures, making it possible to produce even the most complex geometries.Try Anpllocnc’s online quotation system now and get a free instant quote.

SLS Tolerances:
For well-designed parts, tolerances of ±0.010 in. (0.25mm) plus 0.1% of nominal length can typically be achieved. Note that tolerances may change depending on part geometry.
SLS Part Warpage:
Larger part sizes (>7 in.) and parts with thin features are the most susceptible to warp. We recommend maintaining a uniform thickness of 0.125 in. (3.175mm) to ensure stability.
| Standard | Bead blast to remove all powder, which leaves a consistent overall texture. |
| Vapor Smoothing | Significant reduction of surface roughness from 250+ μin RA (as-printed) to 64 – 100 μin RA (after smoothing. Available for PA11 Black. |
| Custom | Secondary options include a primer or dye color that can be applied as well as taps and inserts. |
Selective Laser Sintering (SLS) stands out as a cutting-edge 3D printing technique, often employing nylon—an adaptable engineering thermoplastic—as its primary material. Nylon, a member of the polyamide family, proves highly suitable for functional prototyping and end-use production owing to its outstanding qualities.SLS can produce complex geometries much quicker and easier than conventional machining or molding without sacrificing build quality. Various materials are available for SLS production with properties comparable to those used in traditional manufacturing processes. Materials include:
Next generation Nylon 11 with the elongation and impact strength of the original but with better surface finish and feature definition
Flame, smoke & toxicity (FST) certified Nylon 11 per FAR 25.853
Original high elongation and impact strength SLS material specified in many aerospace products
General purpose Nylon 12 with good surface finish and feature definition with less deformation than Nylon 11
Flame, smoke & toxicity (FST) certified Nylon 12 per FAR 25.853
Glass-filled Nylon 12 with higher tensile modulus & HDT
Electrostatically dissipative with high strength-to-weight ratio
High strength and high temperature mineral fiber-filled plastic
Aluminum-filled Nylon 12 for the appearance of aluminum; also has electrostatic dissipative properties
his material is a mixture fine aluminium particles and polyamide powder and is recommended for metallic appearance. This material is highly stiff and has a shiny look with a matte surface.
This material is a mixture of polyamide powder and glass fibers with a white slight porous surface. This material is commonly used for complex designs (typically used in the automotive industry) due to its high stiffness. It has high temperature resistance when combined with good chemical resistance.
This material displays high weight strength ration and excellent stiffness.
Selective laser sintering, SLS printing, is a powerful 3D printing, additive manufacturing, technology that produces highly accurate and durable parts capable of being used directly in end-use, low-volume production, or rapid prototyping. SLS is one of the most inexpensive options for industrial 3D printing services because it can build parts in bulk without support structures. SLS printing materials are primarily nylon and come with various infills that enhance material properties–from stiff carbon-filled to flame retardant properties. Nylon is the most common material used for the SLS process. The finished parts usually have a rough outer texture. Flexible parts can also be made out of SLS. Nylon parts are known for their strength. Because of the homogeneity of the process, the parts are reliable and can be used as functional parts. The process is relatively inexpensive compared to SLA.
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. SLS is a process that can produce strong and accurate functional parts by sintering the powder into solid parts layer by layer usually with high powered laser beams.
Laser Sintering is a great option when the geometric complexity of a part makes it difficult to produce through other processes or when the anticipated production volume doesn’t justify the time & expense of tooling
SLA&SLS are suitable for the production of small parts, can be directly obtained resin or similar engineering plastic products. The conceptual model is mainly used for prototyping, or to do a simple test and assembly process planning.
Many people are more familiar with FDM-style 3D printing, where plastic filaments or threads are extruded through a print head. SLS is on average 8x faster than FDM printers, and in some cases up to 20x faster. SLS is a high-throughput, high-productivity form of 3D printing.
An FDM extruder dispenses heated filament through a nozzle, much like a hot glue gun. When you use a hot glue gun and pull the trigger, the glue squeezes out where your hand leads. The FDM extruder is mounted on a gantry system, so much like a glue gun, the rate and speed of the nozzle movement is limited by the rate at which the heated filament is extruded. SLS is not limited in this way because the material is not extruded but melted by a laser moving along a grating path at speeds of up to 5000 meters per second. This makes SLS an extremely fast and precise 3D printing method.
Selective Laser Sintering isn’t just for prototyping. It can be used to produce small quantities of production parts – ideal if you’re waiting for your injection mold tooling to be completed.
Because SLS works with thermoplastics, it can be used to quickly and affordably create functional prototypes for new product designs that will later be produced using injection molding. With our cross-functional engineering expertise, we can help you tweak your part designs so they work well in both environments.
SLS can be used to build work holding fixtures to secure metal parts for CNC machining. It’s especially well-suited for larger jigs and fixtures because of the large build volumes it makes possible and its small-feature accuracy.
If tight tolerances are needed, a part can be 3D printed with the critical dimensions oversized. It can then be machined to the required tolerance.
For parts that require excellent impact strength, high temperature performance, water resistance, stiffness and rigidity, or if you need higher resolution or better surface finish, Stereolithography (SLA) is a viable alternative.
If you need better isotropic characteristics, then you should consider Multi-Jet Fusion (MJF).
