Texture

This material is acrylate-based, so there are additional steps to consider when preparing a print. Being white in color, differential shrink, support scaring, rough down-facing surfaces, layering and scuffs/ glove prints will be less apparent than on parts printed in other materials and colors such as black. These defects will still show up in the parts but will be masked slightly by the satin finish of the parts.

Like injection mold tooling practices, adding texture or noise to the part design will further hide these sensitivities and produce a much more uniform looking part that requires little finishing. As a side benefit, it makes the easier to handle when cleaning the parts in their green state which leaves less glove prints and other marks behind. You can use the Add Noise tool in 3D Sprint to add texture to the part globally or locally. The default values are 0.0079” (0.2mm) for Granularity and 0.002” (0.05mm) for Range. The default values make a good texture. If a lighter texture is desired, decrease the Granularity by small increments. Going below 0.004” (0.1mm) will make the texture smaller than a layer thickness and may cause it not to show up well. If a heavier, more distinct texture is desired, use the default Granularity but increase the range in small increments. A range upward of 0.008” (0.2mm) works well.

Example of an Accura AMX Durable Natural Part without texture and two levels of texture. The middle part is using default parameters and the part on the right is using a Granularity of 0.0079” (0.2mm) and Range of 0.0079” (0.2mm).
