Benefits of Selective Laser Sintering (SLS)
SLS stands out among powder-bed 3D printing methods because it doesn’t need support structures. The surrounding unfused powder holds every part in place during printing, so complex shapes like undercuts, internal channels, snap-fits, and multi-part assemblies can be printed as one piece, with no support marks to clean up afterward.
Parts also come out strong in every direction (X, Y, and Z), making them great for functional testing and load-bearing end-use parts. SLS works with a wide range of engineering plastics, including nylon, glass-filled nylon, and flexible TPU, producing parts with impact and chemical resistance close to injection-molded plastic. And since leftover powder can be reused, it also helps cut material waste and cost.
SLS General Tolerances
Our dimensional specifications align with standard SLS industry benchmarks for accuracy and repeatability. Typical tolerances are ±0.3% of nominal dimension, with a lower limit of ±0.3mm for smaller features. Minimum wall thickness is around 0.8mm, and fine details down to 0.5mm are achievable depending on part geometry and orientation.

| PA12 Nylon 12 | ±0.3% or ±0.3 mm (whichever greater) | ±0.4% or ±0.4 mm (whichever greater) | 1.0 mm (0.8 mm minimum for non-load structures) |
| Glass-Filled PA12 | ±0.35% or ±0.35 mm | ±0.45% or ±0.45 mm | 1.2 mm |
| TPU Flexible Elastomer | ±0.4% or ±0.4 mm | ±0.5% or ±0.5 mm | 1.2 mm |
