SLS 3D printing: Everything you need to know
NE Print Shop
SLS 3D printing is a 3D printing technology used for the production of complex and durable components.
SLS 3D printing, also known as selective laser sintering, is a self-supporting additive manufacturing process. In other words, it creates objects layer by layer without needing any additional support structures. It does so by using a powerful laser that selectively sinters thermoplastic polymer powders. SLS 3D printing offers high accuracy, flexibility in design, quick turnaround times, and a wide variety of finishes. It is a popular choice for rapid prototyping and custom manufacturing. While it is susceptible to shrinkage, wrapping, and over-sintering, it offers several advantages over other 3D printing technologies such as FDM or SLA.
The most commonly used material in SLS 3D printing is production-grade nylon. Parts made using this technology are durable and reliable. Moreover, it is capable of creating movable objects such as hinges, mechanical joints, and other complex parts. This makes SLS 3D printing ideal for prototype and production parts. Combined with the fact that it is a fast and efficient method, it can save engineers and manufacturers time and money.
Additionally, SLS 3D printing offers a variety of materials and finishes and a high level of customization. This makes it an ideal choice for different industries. Industries that are particularly keen on this technology include:
However, aside from large-scale manufacturing lines, SLS 3D printing can be of great use for small businesses too. While the initial investment in an SLS machine might seem like a lot, over time, thanks to the low cost of materials and quick turnaround times, it pays for itself.
As already mentioned, nylon is the most commonly used material in SLS 3D printing. Specifically, Nylon 12, also known as Polyamide 12 (PA 12). Depending on the machine and the needs of the project, other thermoplastic polymers may also be used. However, most are both more expensive and more taxing to use. For example, Polyamide 11 (PA 11) and PEEK.
Additives such as carbon fibers, glass fibers, or aluminum can also be used, but materials filled with these additives usually end up being more brittle and displaying anisotropic behavior.
Due to technological advancements, SLS 3D printers are now more compact and affordable than ever. Before recently, these machines were large and costly and, as such, reserved for a very specific type of customer. Today, several benchtop SLS 3D printers are suitable for offices and affordable for small businesses. Even industrial-sized models are considerably more affordable than their predecessors. So now is a great time to purchase one.

SLS 3D printing makes it possible to produce self-supporting, durable, reliable and highly customizable parts quickly and at a low cost. The technology is suitable for a wide range of applications and is a popular choice for engineers and manufacturers due to its advantages over other technologies.
The most commonly used SLS 3D printing material is Nylon 12, a highly durable thermoplastic polymer. It has great tensile strength, environmental stability, and doesn’t crack easily under stress. Its characteristics can be altered with certain additives to suit more specialized use cases.
Some raw materials used in 3D printing, such as powders, filament, or resin, can absorb moisture. This can change its properties and affect the quality of the final product, especially when plastics are in question. Hence, controlling the humidity levels in all production facilities is essential to preventing moisture damage.
SLS 3D printing has a variety of use cases due to its great mechanical properties, durability, quick turnaround times, and low costs of materials. It is particularly beneficial for prototype and production parts that require a high degree of customization, movability, tactile strength, and toughness.
