Selective Laser Sintering
Functional Prototypes and Production Parts in One Day

Laser-sintering is well known as the technology of choice for ensuring the quickest route from product idea to market launch.

Selective Laser Sintering (SLS) is an additive process where layers of powder are deposited, solidified and sintered with a computer-driven laser to form a 3D model.

Selective Laser Sintering produces complex and finely featured parts with exceptional accuracy for design flexibility and verification. Part stacking and nesting mean faster build, more productivity and less waste, making SLS a practical process for final parts.

Because SLS prototypes and parts are not cut from stock, fewer materials and less energy are used. SLS is also consistent with the proprietary HARBEC QMS process and offers accuracy, speed-to-market, and competitive prices: all to your competitive advantage!

Going to a show and need to have fully functional parts? Call us. Or work with us to meet your rapid product development schedule.

With the addition of two 3-D Systems Sinterstations to our QMS™ program, we offer more material choices, more flexibility, and more benefits than ever before. From one to one hundred thousand pieces, we will deliver just what you need when you need it.

Transform 3D Data to Dimensional Objects Quickly

Turn 3D data into three dimensional plastic, elastomer, or metal objects utilizing any, or a combination, of our advanced technologies. Parts from HARBEC's new SLS build up to 11" x 13" x 17" and require no support structures. The variety of SLS materials available and the accuracy of the process allow parts to imitate or actually be a final product.

To expedite your design process, HARBEC's Real-Time Collaboration program enables you to work out details with our design engineers and our expansive library allows us to translate over 50 CAD file types.

Our Rugged Materials Will Withstand Rigorous Testing

With SLS, a wide range of materials such as nylon-like polyamides, glass-filled polyamides, and rubber-like elastomers are available.

SLS prototypes are built of rugged materials that will withstand aggressive functional testing under a variety of conditions. This allows designers to refine and verify part design. SLS parts resist heat and chemicals, are impervious to water, can be painted or dyed, readily joined mechanically or by adhesives and are machinable and weldable. The long term stability of many materials means parts can be used in final application.

The Simple SLS Process

Use the part as is—or sand, anneal, coat or paint it before using it for its intended application.

Take advantage of HARBEC’s new EOSINT M 270: a laser sintering system for the production of tooling inserts, prototype parts and end products directly in metal.

The Direct Metal Laser Sintering (DMLS) technology fuses metal powder into a solid part by melting it locally using a focused laser beam. Similar to SLS, the parts are built additively: layer by layer. Even highly complex geometries are created directly from 3D CAD data, automatically, in just a few hours without any tooling. It is a net-shape process, producing products with high accuracy and detail resolution, good surface quality and excellent mechanical properties.

A wide variety of metals can be direct metal laser sintered, ranging from light alloys via steels to super-alloys and composites.

DMLS is widely used to produce positive parts directly from CAD data. The components can be prototypes, series production parts or even spare parts. Also coming soon: the ability to readily manufacture individualized implants in bio-compatible alloys.

DMLS is also well known as a leading technology for toolmaking using an application known as DirectTool. With its high accuracy and surface quality, the direct process eliminates tool-path generation and multiple machining processes such as EDM (Electrical Discharge Machining). Tool inserts are built overnight or even in just a few hours. With DMLS, the freedom of design can be used to optimize tool performance, for example by integrating conformal cooling channels into the tool.
