What mean sls 3d printing prototype ?


Selective Laser Sintering (SLS) is a 3D printing technology that uses a laser to selectively sinter (fuse) powdered material, typically nylon or other polymers, layer by layer, to create a three-dimensional object. If you're looking to create an SLS 3D printing prototype, here are the general steps you might follow:

About us

1.Design Your Prototype:

  • Use 3D modeling software (such as AutoCAD, SolidWorks, or Blender) to create a digital 3D model of your prototype. Ensure that your design is suitable for the SLS printing process.

2.File Preparation:

  • Save your 3D model in a file format that is compatible with the SLS 3D printer. Common formats include STL (Standard Triangle Language) and OBJ (Wavefront Object).


  • Some 3D printing software or online services provide pre-processing tools. These tools may include features for orienting, scaling, and adding support structures to your model.

4.Material Selection:

  • Choose the appropriate SLS printing material. SLS commonly uses powdered nylon, but other materials like glass-filled nylon, TPU, and more may be available. The material choice depends on the properties you need in your prototype.

5.SLS Printing:

  • Submit your 3D model to an SLS 3D printer. The printer will follow the digital model's instructions to selectively sinter layers of powdered material, building up the prototype.


  • After each layer is sintered, it's allowed to cool before the next layer is added. This helps ensure that the layers fuse correctly and maintain structural integrity.


  • Once the printing is complete, the prototype may need to undergo post-processing. This can involve removing excess powder, cleaning the part, and possibly surface finishing or treating it depending on your requirements.

8.Inspection and Testing:

  • Inspect the printed prototype for quality and accuracy. Test its functionality if applicable.

9.Iterate if Necessary:

  • If the prototype doesn't meet your expectations, you may need to go back to the design stage and make necessary adjustments. This iterative process is common in product development.


  • Keep detailed documentation of your prototype, including design files, printing parameters, and any post-processing steps. This information is valuable for future reference or for reproducing the prototype.

Remember to check with the specific 3D printing service or equipment you are using, as the exact steps and requirements may vary.
