Additive Manufacturing SLS

As an experienced manufacturer, Fathom is known for producing high-quality additive manufacturing parts using selective laser sintering (SLS). Whether your project is time-sensitive, requires high precision, or is highly complex or short project run related, our team can meet the requirements of your project. SLS is just one of the many manufacturing technologies offered by Fathom. Get started today.

How Does SLS (Selective Laser Sintering) 3D Printing Work? / /

Selective laser sintering is a powder-based additive manufacturing method used to make end-use parts, models, and prototypes. During the SLS process, a thin layer of powder is spread over the build volume. A laser is used to sinter cross-sections of the part, which fuses the powder. Any unused powder serves as a support structure, and no support removal is needed. Once the part has been formed, it is excavated and bead blasted.

Benefits of Using SLS for Additive Manufacturing? / /

There are multiple benefits of SLS. As mentioned, no support material is needed, which results in a faster turnaround. It is possible to produce pieces with complex geometries in small to medium batches. SLS parts have good isotropic mechanical properties. Any unused material can be reused. Multiple parts can be produced simultaneously, which maximizes the build space of the SLS machine.

Types of Products that can be Made Using SLS Additive Manufacturing? / /

Selective laser sintering is used to make parts and prototypes for various industries. Fuel tanks, ductwork, clips, clamps, limb replacements and brackets have all been made using SLS. Engineering, healthcare, and automotive are just a few of the industries that use SLS components.

Additive Manufacturing Services Offered By Fathom / /

Fathom offers multiple additive layering technologies, including selective laser sintering. Additive manufacturing is the process of forming parts by layering materials. In addition to SLS, Fathom also offers fuse deposition modeling, stereolithography, multi jet fusion, polyjet, direct metal laser sintering, etc. Selective laser sintering is just one of 28 manufacturing processes offered by Fathom.

Additive Manufacturing FDM FAQs / /

Q: Does Fathom offer additive manufacturing services?

A: Yes, Fathom offers additive manufacturing services.

Q: What is an additive manufacturing machine?

A: An additive manufacturing machine produces a part by placing material in layers, gradually adding more raw material until a part is formed.

Q: Is Fathom ISO certified?

A: Fathom’s certifications include ISO 9001:2015, ISO 9001:2015 Design, and ISO 13485:2016. For site-specific certifications, please visit https://fathommfg.com/fathom-manufacturing-certifications.

Q: What is SLS manufacturing?

A: SLS is a powder-based manufacturing technology used to create end-use parts, prototypes, and models.

Q: What does the SLS stand for in additive manufacturing?

A: SLS stands for selective laser sintering.

Q: What is the difference between SLS and SLA?

A: Both SLS and SLA are additive manufacturing processes. SLS parts are made within a fully enclosed machine where the part cannot be viewed as it is printed. SLA parts are made on a machine enclosed with glass or plastic and the part can be viewed as it is made. SLA produces complex parts that can be brittle. SLS have a slightly rougher surface finish but similar detail and complexity. SLS parts can be used for mechanical applications.

Q: What is the material used in SLS?

A: Materials used in selective laser sintering include PA12, TPU 88A, PA12 glass bead, PA 11, and PA 11 fire retardant.
