Build Plastic Parts with Our Selective Laser Sintering 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, then solidified with a computer-driven laser to form a 3D model. Selective Laser Sintering produces complex and finely featured parts with exceptional accuracy and unlimited design flexibility. Part stacking and nesting mean faster build times, more productivity and less waste, making SLS a practical process for low volume production parts. Because SLS prototypes and parts are not cut from stock, less material and less energy is 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!
Get a handle on your ideas . . . within a week! Going to a show and need to have fully functional parts? Call us. We will work with you to meet your rapid product development schedule. With the capacity of two 3-D Systems Sinterstations in 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 equiptment 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, final products. 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 the ability 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 able to be machined, and welded. The long term stability of many materials means parts can be used in final applications.
The Simple SLS Process
- Start with your 3D CAD data.
- Enter the data into the Sinterstation.
- As the process begins, a precision roller mechanism automatically spreads a thin layer of powdered SLS material across the build platform.
- Using data from the generated STL file, a CO2 laser selectively draws a cross section of the object on the layer of powder. As the laser draws the cross section, it selectively “sinters” (heats and fuses) the powder creating a solid mass that represents one cross section of the part.
- The system spreads and sinters layer after layer until the object is complete.
- Remove the part.
Stereolithography is an additive manufacturing process which employs a vat of liquid ultraviolet curable photopolymer “resin” and an ultraviolet laser to build parts’ layers one at a time. For each layer, the laser beam traces a cross-section of the part pattern on the surface of the liquid resin. Exposure to the ultraviolet laser light cures and solidifies the pattern traced on the resin and joins it to the layer below.
After the pattern has been traced, the SLA’s elevator platform descends by a distance equal to the thickness of a single layer, typically 0.05 mm to 0.15 mm (0.002 in to 0.006 in). Then, a resin-filled blade sweeps across the cross section of the part, re-coating it with fresh material. On this new liquid surface, the subsequent layer pattern is traced, joining the previous layer. A complete 3-D part is formed by this process. After being built, parts are immersed in a chemical bath in order to be cleaned of excess resin and are subsequently cured in an ultraviolet oven.
Stereolithography requires the use of supporting structures which serve to attach the part to the elevator platform, prevent deflection due to gravity and hold the cross sections in place so that they resist lateral pressure from the re-coater blade. Supports are generated automatically during the preparation of 3D Computer Aided Design models for use on the stereolithography machine, although they may be manipulated manually. Supports must be removed from the finished product manually, unlike in other, less costly, rapid prototypingtechnologies. (-Wikipedia)
Build Metal Parts with Our Direct Metal Laser Sintering Take advantage of HARBEC’s EOSINT M 290 and EOSINT M 270: laser sintering systems for the production of tooling inserts, prototype parts and direct manufactured parts in various metals. 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. DMLS is also well known as a leading technology for tool making 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.
HARBEC is known for its ability to CNC machine exactly what is required before you ever invest a penny in hard tooling or design something that cannot be molded. In about two weeks HARBEC can provide functionally correct, dimensionally accurate engineering prototypes from your supplied CAD files.
