Product and parts manufactured using Selective Laser Sintering (SLS) or Multi Jet Fusion (MJF) for example, can be polished using tumblers or vibro-machines to achieve a smoother surface texture. A tumbler contains chips, for example ceramic chips, and vibrates to gently erode the surface layers of the part to achieve a smooth and polished look and feel. The media used and time in the tumbler produces varying effects of surface smoothness.
At WAZP, we use surface smoothing and polishing technologies, including standard technology (tumblers) and/or our proprietary techniques to achieve a specified surface texture, and finish. The Surface Roughness (Ra) and Surface Gloss (Ga) is dependent on the parts or product's final specifications and our customers' requirements.
What is Ra and Ga?
Surface Roughness (Ra) is the measure of the finely spaced micro-irregularities on the surface texture which is composed of three components, namely roughness, waviness, and form.
Surface Gloss (Ga) or simply gloss is a measure of how reflective a material is at a specified angle based on refractive index.
