The same slice image, with different Grey offset values Anti-aliasing on Support #īy default, supports do not have anti-aliasing applied. Adjusting this parameter can have a significant impact on the quality of anti-aliasing. Other resins, often more qualitative, are more reactive and start to harden with less light intensity. However, some resins need more time than others to start this light curing process and, therefore, require more “white” color in the pixels forming the anti-aliasing. It is important to consider that the resin needs a minimum exposure to UV light to begin to solidify. 3D model by Bold miniatures, photo by DosGrajos. You can see the impact of the grey offset value on the quality of the anti-aliasing. The Grey Offset parameter allows you to edit the contrast of the grey levels, and also the grey value that acts as the starting point for the anti-aliasing. This option is strongly recommended to improve surface definition. This mode also consumes a lot of memory on the graphics card and can, in some cases, cause the 3D display of the application to be lost. This mode, available in all antialiasing types, offers an optimal quality for antialiasing, but it can significantly increase the computation time when exporting, especially on machines with limited performance. A lower value will concentrate the spreading on a smaller distance but will also limit the number of grey values. The higher the value, the more the grey level stretches along the image, allowing a smoother transition. The Level allows you to define the spread of the anti-aliasing along the curves of the 2D image. For example, 2 pixels for a 50 micron printer in horizontal resolution and 3 for a 35 micron printer. The smaller the pixels of your 3D printer, the higher the value. It is important to match the value to the resolution of your printer. Increasing the value will result in much smoother surfaces, but there will be a loss of definition of micro details. The Radius (Blur) value allows you to change the intensity and especially the spread of the blur applied to the edges of the image. Be careful, some of them can greatly affect the result obtained and/or the calculation performance of the final slices. The anti-aliasing offers several settings and parameters, available depending on the modes you choose. It is a mix between Smooth Surface anti-aliasing and Sharpen Details. However, there is a strong contrast at the surface border, and the blur is applied around it. This mode is similar to the Smooth Surface mode, with the same options. The Grey offset will allow better control of the starting point of the resin solidification. The use of the Level value will be important, often used at its maximum, to manage the spread of the greyscale level. This antialiasing mode is the historical one of Lychee Slicer, which offers very sharp details, but still leaves some aliasing potentially still visible, depending on the resin used. The Grey Offset allows for better control of the beginning of the resin solidification process. This will further improve the quality of the surface and will slightly limit the effect of stacked layers that can be seen on top of the curves. The algorithm applies an anti-aliasing effect on the edges of the image of each layer and then applies a slight blur of a few pixels on top of the result. This is the recommended mode for maximum anti-aliasing effect. In particular, for 3D printers that offer a very high horizontal resolution, under 35 microns as the pixel size makes the use of anti-aliasing less needed.

This choice remains relevant for models composed of many small and fine micro details. No anti-aliasing effect is applied to the edges of the images to be printed.

This also means that it’s important to consider that one setting may not give the same result from one resin to another, as well as from one exposure time to another. Some entry-level resins may not respond as well as high-quality ones. It’s also important to note that not all resins react the same way to anti-aliasing. Most of the time, we recommend using Smooth Surface anti-aliasing. Lychee Slicer provides different Antialiasing algorithms, producing different results based on your needs. The Antialiasing is designed to smooth the surfaces of your 3D print by adding extra greyscale pixels on the curvature of the images that the 3D printer will display on the screen.
