SLS 3D printing is one of the popular additive manufacturing technologies for building prototypes and low-volume end-use parts. It builds functional and robust models from reliable materials, such as nylon (PA12). SLS rapid prototyping makes it possible to create prototypes with complex geometries and features because it prints one layer at a time from powdered material. The powder surrounding the part eliminates the need for support structures during printing, allowing you to save time and minimize the need for post-processing.
How does it work? SLS stands for selective laser sintering, and it was first developed in the 1980s. However, it only achieved commercial success in the early 1990s. The printing process builds successive layers on a build chamber in an SLS machine. Every layer is fused with a laser and shaped to create a three-dimensional part. SLS rapid prototyping achieves complex shapes crucial to many industries looking to build working models and prototype parts. Applications of SLS 3D printing SLS prototypes are highly accurate, making them ideal for any stage of the production process. They can be concept models or parts ready for testing and presentation. SLS 3D printing can also produce end-use production parts for low-volume manufacturing requirements. Selective laser sintering lets you build a range of products, including brackets, enclosures, cases, and ducting. Materials used Powdered nylon (PA12) is preferred for SLS rapid prototyping. It is a fine white powder with well-balanced properties to suit various applications, especially for building high-quality, durable, and fully functional plastic parts. Its excellent mechanical properties make it a suitable alternative to conventional injection molding plastics. PA12 is biocompatible, so it's suitable for medical applications like prostheses. Its high-abrasion resistance also makes it ideal for building parts with articulated components. Finishing options The printing process builds parts from powder, so a rough surface finish is inevitable. The resolution may not be as high as other 3D printing processes, too. However, SLS rapid prototyping services can finish the nylon parts to improve surface smoothing and aesthetics. Your parts can be finished by dyeing, smoothing, lacquering, spray painting, etc.

Rapid prototyping is the fast fabrication of physical objects using CAD during the design phase of the product life cycle. It’s applicable throughout your design process, from conceptualization to final testing. Effective, fast prototyping helps product designers and engineers avoid design flaws and potential issues. A tangible version of their design allows them to properly analyze and study its features and verify its aesthetics and function, allowing for necessary improvements to enhance the quality while accelerating the time to market.
Today, you’ll find many rapid prototyping technologies from reputable prototype manufacturing companies in China. Here are some of them: Fused deposition modeling (FDM) FDM is among the versatile additive manufacturing or 3D printing technologies that builds parts by extruding a plastic filament through a nozzle, then laying it down on a build chamber one layer at a time. This way, it can create parts with complex geometries using a wide range of materials, such as ABS, nylon, Ultem, and PC. Some of its applications include building functional bits, housings, and enclosures. Although it’s ideal for fast prototyping, the process has restrictions that will require support material for any overhanging features. The supports are eliminated post-process. The 3D printing technology is also versatile for low-volume production. Stereolithography SLA 3D printing or stereolithography builds aesthetic models from the photocurable resin. A high-powered UV laser cures the resin one layer at a time. Some of its perks include a good surface finish and great accuracy in the CAD. Similar to FDM, SLA requires support structures, which will be removed after printing. Selective laser sintering SLS 3D printing enables fast prototyping using durable nylon (PA12). It is used extensively to build functional and aesthetic prototypes with complex features and overhangs without needing support structures. The process is versatile for low-volume production, too. Build your prototypes fast Choosing an ideal fast prototyping method can be overwhelming, especially considering your timeline, budget, and other factors. However, partnering with a reputable, experienced rapid prototyping expert can help you make informed choices. They can review your project and make suggestions that could save you time and money. |
