In order to work better for 3D printing, the dimensions of each braille dot has been set to the maximum allowed. This can cause the dots to be oversized on 3D printers with insufficient dimensional accuracy. Printing with anything larger than a 0.4 nozzle will likely lead to print quality problems as well. The braille dots are very small compared to the resolution that most 3D printers are capable of printing to, and so finer detail settings must be used when slicing the software.

Due to the close positioning and small size of the braille dots, stringing is possible and may require some post-processing to clean the dots up to an acceptable level. It may also be possible to reduce or eliminate stringing by adjusting the nozzle temperature and retract settings for your printer. If strings are observed on the print see the post-processing instructions for information on how to clean the dots up.
