How accurate is SLS printing?

How accurate is SLS printing?

Selective laser sintering (SLS) is a particularly accurate process that is often used to produce complex geometries. SLS printing has a dimensional tolerance of ± 0.3% and a lower limit of ± 0.3 mm. This can result in warping, especially in larger SLS parts.

What is the tolerance of 3D printing?

General information about tolerances in 3D printing In most additive technologies, the dimensional tolerance is at least 0.1 mm. This means that the deviations in 3D printing are greater than in other technologies, such as injection molding or CNC machining.

What is SLS print?

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.

Is SLS stronger than FDM?

Comparatively, the FDM parts tested at -60°C show a difference in tensile strength 30MPa greater than SLS. This means that the mechanical properties of SLS parts are much more isotropic (up to 3 times more at low temperatures!) than the Ultem 9085 FDM parts.

Where is SLS printing used?

Its most common application is in prototype parts early in the design cycle such as for investment casting patterns, automotive hardware, and wind tunnel models. SLS is also increasingly being used in limited-run manufacturing to produce end-use parts for aerospace, military, medical, and electronics hardware.

Why is selective laser sintering ( SLS ) used in 3D printing?

Selective laser sintering (SLS) 3D printing is trusted by engineers and manufacturers across different industries for its ability to produce strong, functional parts.

What makes a good part for SLS manufacturing?

SLS production parts are strong, water and air-tight, heat resistant and repeatable. This robust process can build parts for all stages of the production lifecycle, from prototyping to low-volume manufacturing opportunities.

How big of a wall do you need for SLS?

We recommend all SLS parts have a minimum wall thickness of 0.040”. See the SLS design guidelines for more details. What is the largest part size you can make with SLS?

What kind of 3D printer do you need for media blasting?

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. As the unfused powder supports the part during printing, there’s no need for dedicated support structures.
