The Material Of SLS 3D Printing Services

During the molding process, the unsintered powder acts as a support for the cavity and cantilever of the model, so SLS-molded workpieces do not require support structures like SLA-molded workpieces. Compared with SLA, the materials used in the SLS process are relatively rich, mainly including paraffin, polycarbonate, nylon, slender nylon, synthetic nylon, ceramics and even metal.

When the workpiece is completely formed and completely cooled, the worktable will rise to its original height. At this time, the workpiece needs to be taken out and the powder on the surface of the model needs to be removed with a brush or compressed air.

The SLS process supports a variety of materials, forming workpieces without support structures, and high material utilization. Although the price and material price of SLS equipment are still very expensive, the material needs to be preheated before sintering, and the material will volatilize odor during the sintering process, and the working environment of the equipment is relatively demanding.

Materials that can be successfully processed by SLS are paraffin, polymer nylon, carbon fiber, glass fiber, polymer, metal, ceramic powder and their composite powder materials

What Is SLS 3D Printing? – SLS 3D Printing Define

SLS 3D printing technology, SLS is called powder sintering in the industry, grasping two key words, powder and sintering, are the characteristics of SLS, SLS printing technology uses powder to spread a layer of powder material on the upper surface of the formed part, And heated to a certain temperature just below the sintering point of the powder, the control system controls the laser beam to scan on the powder layer according to the cross-sectional profile of the layer, so that the temperature of the powder rises to the melting point, sintered and formed with the lower part. achieve bonding. After the completion of one layer, the worktable is lowered by one layer of thickness, and the spreader rolls spread a layer of uniform and dense powder on it to sinter a new layer of cross-section until the entire model is completed.

How Does SLS 3D Printing Work? – Steps of SLS 3D Printing Process

  1. First, heat the powder bin and the build area to a temperature close to the melting temperature of the material, and lay a layer of powder material.
  2. Second, use the laser to scan the cross section of the layer, raise the powder temperature to the melting point, and selectively sinter the area to be printed to form a bond.
  3. After the sintering is completed, the building platform moves down, the scraper is covered with a layer of powder material, and the content of step 2 is repeated until the entire model is completed.
  4. After the printing is completed, the forming chamber is cooled (generally the temperature is below 40 degrees), and the parts can be taken out for subsequent processing.

The Advantage Of SLS 3D Printing

The main advantage of SLS is that it does not require a supporting structure. Unsintered powder provides all necessary support for the part. Therefore, SLS can be used to create free-form geometries, as long as it is within the parameters of the printing process, designers can display their talents as they want without worrying about manufacturing.When printing with SLS, especially for small batch production, it is very important to make full use of the entire build volume and increase the print-to-bin ratio (the volume ratio of the printed product in the entire print bin).

After the maximum print height is determined according to the layout requirements of the printed products, it will take approximately the same amount of time to print regardless of the number of printed products in the print control. This is because the speed of laying powder on each layer determines the total printing time (laser scanning happens very quickly), and the machine will have to cycle through the same number of layers.Therefore, for a factory that does SLS process 3D printing services, it can use a large number of orders, and optimize the combination of order products as much as possible in the same printing warehouse for production, which will greatly reduce the printing cost and improve the printing speed. (Reduce the time of waiting for orders and making up orders, and start production quickly).

  • There are many materials that SLS can use. The materials that can be used include polymer, metal, ceramic, gypsum, nylon and other powders. However, due to the refinement of the market, metal materials will now be called SLM. Now the material used in SLS should account for 90% of nylon material, so we usually default to SLS as printing nylon material.
  • Accuracy, now the normal accuracy is to achieve a tolerance of plus or minus 0.2mm.
  • No need for support, it does not need a support structure, the suspended layer in the lamination process can be directly supported by the unsintered powder, which should be one of the biggest advantages of SLS.
  • The utilization rate of materials is high, and the utilization rate of materials is high. Since there is no need for support and no need to add a base, it has the highest material utilization among several common 3D printing technologies, and the price is relatively cheap, but it is more expensive than SLA.
