Custom Selective laser sintering (SLS) at Mucision

Selective Laser Sintering (SLS) is a potent 3D printing technology that produces highly precise and robust parts suitable for end-use, low-volume production, or rapid prototyping. As one of the most cost-effective industrial 3D printing solutions, SLS can fabricate parts in bulk without requiring support structures. SLS materials, primarily nylon-based, offer various infills that improve material properties, ranging from stiff carbon-filled to flame-retardant characteristics.

Utilizing additive manufacturing layer technology, SLS employs a high-power laser, such as a carbon dioxide laser, to fuse small plastic powder particles into a desired three-dimensional shape. The laser selectively melts the powdered material by scanning cross-sections generated from a 3D digital model (e.g., a CAD file) on the powder bed’s surface. After each cross-section scan, the powder bed is lowered, a new material layer is applied, and the SLS process is repeated until the part is completed.

What is SLS?

Selective Laser Sintering (SLS) is a powder bed 3D printing technology that manufactures highly precise and robust parts suitable for end-use and low-volume production. Often considered a relative of the renowned metal 3D printing technology, Direct Metal Laser Sintering (DMLS), both processes employ a laser to accurately fuse powder layers, constructing parts from a 3D CAD file. SLS specializes in nylon or polyamide powder particles, whereas DMLS utilizes metal particles. This technology is increasingly popular for prototyping and low-volume production.

SLS Finishes Available at Mucision

SLS parts are de-powdered with a sandblasting process and manual powder removal. Internal holes may be drilled to size if accessible. The finish is white matte (fine sugar-cube).

With a variety of color options, including black, blue, green, red, and yellow, the dye penetrates approximately 0.010 inches deep. While batch-to-batch consistency may slightly differ, black offers the highest uniformity, ensuring reliable and aesthetically pleasing results for diverse applications.

AMT PostPro3D is an advanced automated post-processing technology that delivers a superior surface finish. Vapor smoothing transforms surfaces from matte to semi-gloss while sealing and enhancing mechanical properties, ensuring consistent and aesthetically pleasing results for production. Additionally, vapor-smoothed components can be dyed, further expanding their versatility and customization options.

The Standard finish undergoes abrasive media tumbling, reducing visible grow lines and softening sharp edges. This process results in an eggshell finish that provides a smoother and more refined appearance compared to untreated surfaces, improving overall aesthetics and tactile appeal.

Mucision provides additional SLS finishing and customization options upon request.

The provided table outlines the standard tolerances for selective laser sintering. However, various factors such as build stresses and geometric complexities may lead to deviations in tolerances and flatness. Designs featuring thicker geometries, flat or broad parts, and uneven wall thicknesses may experience significant deviations or warping. Enhanced tolerances can potentially be achieved through manual quote review and successful prototyping, subject to case-by-case approval. General tolerances are applicable prior to secondary finishing or post-processing unless otherwise stated.
