Selective Laser SinteringServices and Capabilities

Selective Laser Sintering (SLS) fuses thermoplastic powder layer by layer into strong, functional parts. It needs no tooling and no support structures, which makes it a practical choice for low-volume production and fast, testable prototypes.

About Our SLS Service

SLS turns thermoplastic powder into durable, functional parts. A laser fuses each layer of powder, and the surrounding loose powder supports the part as it builds, so there are no support structures to remove and complex geometry comes at no extra cost.

That makes it a favorite among engineers for low-volume production. You can consolidate several components into one part, build intricate internal features, and move from file to finished part without committing to tooling.

Why Engineers Choose SLS

SLS combines strength, speed, and design freedom, which is why it shows up everywhere from prototyping benches to motorsport programs.

Cost-Effective at Low Volume

SLS often beats injection molding on ROI for short runs, since there is no tooling to pay for before the first part.

Fast Functional Iteration

Parts come off the machine strong enough to test, so you can iterate quickly. The same speed supports work like Formula 1 wind tunnel testing.

Material Versatility

We print mostly nylon-based powders, available in unfilled, glass-filled, and carbon-filled grades plus flexible TPU 88A.

Applications of SLS

SLS suits work that needs quick turnaround and durable parts. It handles intricate geometry and can consolidate multiple parts into one component to simplify assembly.

Our SLS Machines: EOS P 770 and P 396

We run SLS on two EOS platforms. The EOS P 770 is one of the largest laser sintering systems available. Its dual lasers scan the powder bed in parallel, so large parts and densely nested builds come off the machine quickly, and the long build envelope lets us print big components in one piece instead of bonding sections together.

The EOS P 396 is our mid-size system. A single 70-watt laser and a 340 x 340 x 600 mm build volume make it a good fit for prototypes, smaller runs, and faster turnaround without tying up the large machine. Parts nest freely in the powder bed on both, so a single build can carry one large housing or hundreds of small parts.

Our Experience & Capacity

We have 30+ years of experience with SLS, going back to our first machine, a DTM 2000, in 1995. That work spans a range of industries and applications, from prototype development to full production. We build parts for automotive, aviation, and consumer goods programs, and we scale the same process from a single part to a production run.

Whether you need a quick functional prototype or end-use parts, we can recommend the right nylon grade and turn the job around on a reliable timeline. Explore the rest of our manufacturing capabilities to see how SLS pairs with our other additive and traditional processes.

Example SLS Parts

From production equipment housings and industrial machine guards to patient-specific dental appliances, SLS handles structural and skin-contact applications alike.
