You can use a 3D printer to construct a variety of three-dimensional objects physically from digital 3D models. But you can boost the quality and usability of the 3D-printed object only by choosing the appropriate 3D printing technologies. Engineers often opt for selective laser sintering (SLS) as a fast and cost-efficient 3D printing technology. You can further leverage this widely used 3D printing technology to construct items with higher dimensional accuracy and better chemical and mechanical properties.

While planning selective laser sintering applications, you have the option to choose from various production-grade nylon materials in powder form. You can further boost the SLS 3D printing process using 3D nesting software. Enterprises from various sectors use SLS 3D printing technology to print production parts, complex prototypes, innovative tools, and complex parts. They have been extending selective laser sintering applications by creating new use cases regularly.

Varying Selective Laser Sintering Applications and Use Cases

Minimize Material Wastage

Selective laser sintering is often described as a zero-waste 3D printing technology. Unlike other 3D printing technologies, SLS enables engineers to recycle-sintered powdered materials. The non-sintered powdered materials can be recycled after the 3D-printing process without investing in extra time and effort. The new-age SLS 3D printers are built with features to combine new powder and recycles powder seamlessly. That is why; enterprises from various industries opt for selective laser sintering to curtail overall printing costs by reducing both material consumption and material wastage.

Customization and Low-Volume Production

In addition to minimizing material wastage, selective laser sintering is one of the fast 3D printing technologies. Its effectiveness in reducing printing time and cost makes SLS one of the preferred additive manufacturing technologies for low-volume production. Engineers further use an SLS 3D printer to produce customized products and models quickly based on varying customer needs. Enterprises from many sectors facilitate low-volume production and product customization through selective laser sintering applications.

Increase Throughput

SLS enables enterprises to produce customized parts in low-volumes. It further constructs parts and models with no support structures. Hence, enterprises leverage this industrial additive manufacturing technology to deliver a higher number of parts in increasing throughput. The additive manufacturing technology allows engineers to increase throughput without impacting the part’s quality, resolution, accuracy, and surface finish. Many enterprises these days opt for new-age SLS 3D printers to increase throughput and accelerate high-volume production by applying 3D nesting techniques.

Replace Subtractive Manufacturing Methods

SLS is one of the fast and most cost-efficient 3D printing technologies. It enables manufacturers to build production parts, complex prototypes, and end-use components without escalating costs. The manufacturers can further create strong and durable products using a variety of materials. SLS makes it easier for engineers to eliminate the design restrictions associated with conventional production methods. That is why; manufacturing companies find it easier to replace subtractive manufacturing methods with selective laser sintering.

Facilitate Rapid Prototyping

As mentioned earlier, selective laser sintering forms structures by sauntering powder filaments using a high-power laser. The high-power laser beams sinter and blends small powdered grains more efficiently. Hence, it becomes easier for engineers to produce complex prototypes with high precision while experimenting with multiple materials. Also, the engineers can use and evaluate the 3D-printed prototypes immediately after the post-processing stage. Selective laser sintering is currently used widely by manufacturers to add accuracy and precision to the rapid prototyping process.

Produce Heat-Resistant and Chemical-Resistant Parts

SLS facilitates the construction of strong and durable parts using a variety of materials. Engineers also have the option to use 3D printing technology to produce functional parts and tools that can resist both heat and chemicals. They can further produce parts with complex geometries, mechanical joints, or living hinges without increasing printing costs. That is why; SLS is currently used widely by engineers to produce a wide variety of industrial products according to varying process needs.

Create Innovative Tooling

The filaments and materials used in the SLS 3D printing process are effective in enduring a higher amount of stress and absorbing moisture. Also, selective laser sintering helps enterprises to create tools and items that are both strong and durable. That is why; enterprises opt for selective laser sintering to produce a variety of tools, fixtures, and jigs with intricate patterns and complex geometries. Engineers evaluate and fine-tune these complex and innovative tools through rapid prototyping.

Simplify Jewelry Design and Production

While using selective laser sintering, engineers have the option to use metal-based materials like copper polyamide or rapid steel. The support for metal-based materials makes SLS one of the widely used 3D printing technologies in the jewelry industry. Jewelry designers collaborate with 3D artists and engineers to design new jewelry pieces through the direct fabrication of metal designs. Many jewelers further use SLS printers to design personalized and unique pieces of jewelry for their clients.

Keep Medical Treatments Safe

Selective laser sintering is one of the 3D printing technologies that are compatible with commonly used dental materials like thermoplastic, plastic, metal, and ceramic. Also, it produces dental prosthetics with a higher accuracy level. That is why; manufacturers from dental industries opt for this industrial 3D printing technology to fabricate personalized dental prosthetics using ceramic or metal. Dentists have been integrating SLS into their routine practice to perform dental treatments safely. Likewise, physicians use SLS 3D printers to conduct feasibility studies by producing components and prototypes on-demand.

You can opt for SLS 3D printing to construct strong and durable three-dimensional items with high-level accuracy. But you must focus on streamlining the SLS 3D printing process while comparing selective laser sintering applications. Also, you should focus on customizing the printing process by choosing the right SLS 3D printer and the right material.
