SLS Finishing Options

In Selective Laser Sintering (SLS), finishing processes are applied after printing to enhance surface appearance, improve part handling, and meet end-use functional requirements. At Panashape, all parts are depowdered as part of the standard workflow, and customers can select additional finish options to match their application needs.

We offer four finishing levels: Standard, Dye, Shot Peened, and Vapor Smoothing. All materials can be dyed, but Shot Peen and Vapor Smoothing are available only for PA12 Nylon due to material compatibility.

Standard Finish

All SLS parts receive a thorough depowdering to remove loose powder from surfaces and cavities. This results in a matte, textured surface that reflects the raw condition of the material post-print.

This finish is best suited for functional parts where surface appearance is not a concern. It’s commonly used for internal assemblies, fixtures, or components that require dimensional accuracy but not aesthetic refinement.

Black Dyeing

Black dye is available for all printed materials. We use a high-quality polyamide-specific dye process that penetrates the surface and creates a uniform, durable black finish. This dye doesn’t affect part geometry or add thickness, making it ideal for tight-tolerance components and complex geometries.

Dyeing is often selected for customer-facing components, low-glare applications, or any use case where white or gray raw materials are not desirable. Other colors may be available upon request for volume orders, but black remains the most consistent and functional option for everyday use.

Shot Peened Finish (PA12 Only)

Shot peening improves surface uniformity through a controlled blast of fine spherical media. This reduces surface roughness, removes minor defects, and gives the part a semi-satin look and smoother feel.

This option is currently available only for PA12 Nylon due to the way glass-filled and elastomer materials respond to impact. Shot peened PA12 parts are often used in handheld products, enclosures, or components requiring improved cosmetics without chemical treatment.

Vapor Smoothing (PA12 Only)

Vapor smoothing is a chemical finishing process that selectively melts the outermost surface of the part, creating a glossy, sealed finish. It improves surface cleanability, reduces porosity, and enhances moisture and chemical resistance.

This process is available only for PA12 Nylon, as other materials may not respond predictably to the vapor environment. Vapor-smoothed parts are often used in medical, consumer-facing, or environmental exposure applications.
