What is SLS technology?

Selective laser sintering is an additive manufacturing (AM) technology that uses a high power laser to sinter small particles of polymer powder into a solid structure based on a 3D model. SLS 3D printing has been a popular choice for engineers and manufacturers for decades.

How does a SLS work?

The SLS 3D printer uses a laser as a energy source which selectively melts powdered plastic material, fusing them together into a 3D printed part. After the melting process is completed, the building platform is lowered, and a new layer of powder is added.

What is difference between SLS and SLM?

To nutshell it, if you’re working with an alloy of some sort, you’ll go SLS or DMLS; if you’re working with say, pure titanium, you’ll go with SLM.” So in lay terms, SLM is stronger because it has fewer or no voids which helps prevent part failure but is only feasible when using with a single metal powder.

What is SLS machine?

Selective laser sintering (SLS) is a powder bed printing technology. The SLS machine begins sintering each layer of part geometry into a heated bed of nylon-based powder. After each layer is fused, a roller moves across the bed to distribute the next layer of powder.

Is SLS cheaper than SLA?

Another factor is cost. SLA and resin-based printers are now available for less than $500 USD, while SLS machines are still well over $5,000 per unit. And in both designs, the cost is compounded over time, as the materials are often proprietary and quite expensive.

What is SLM in additive manufacturing?

Selective laser melting (SLM) is a part of additive manufacturing where a high-power-density laser is used to melt and fuse metallic powders together. This is a fast developing process that is being implemented in both research and industry.

Is DML same as SLM?

As DMLS and SLM are functionally the same, they share many advantages and limitations, with a few exceptions. Naturally, both share many advantages with other 3D printing technologies.

What is SLS?

SLS is built on proven hardware from the space shuttle and other exploration programs while making use of cutting-edge tooling and manufacturing technology in order to significantly reduce development time and cost. Orion Spacecraft Adapter Interim Cryogenic Propulsion Stage Solid Rocket Boosters RS-25 Engines (4) Core Stage Launch Vehicle

What is post-processing in SLS 3D printing?

Post-processing: The finished parts need to be removed from the build chamber, separated, and cleaned of excess powder. The powder can be recycled and the printed parts can be further post-processed by media blasting or media tumbling. For the detailed workflow, see the “ The SLS 3D Printing Workflow ” section below.

What is the surface finish of an SLS part?

SLS parts have a slightly grainy surface finish, but almost no visible layer lines. Media blasting or media tumbling SLS parts is recommended for a smoother surface finish. This example part was printed on a Formlabs Fuse 1 benchtop industrial SLS 3D printer.
