Design guidelines for including text on polymer AM parts

The inclusion of text on a polymer part means that logos, branding, instructional messages, unique identification codes or batch numbers can be incorporated into the CAD design and generated during the build process. Text can be embossed or engraved.

General design guidelines are as follows:

Font: For best results we recommend using Arial font. Other fonts can be used. We advise you speak to our CAD experts for advice on whether they would build well on your part.

Size: Font size depends on the orientation of the build. A good minimum size recommendation is 14 point. Anything less than 8-10 point could become difficult to read.

As a general guide, 1pt = approx. 0.25mm. Therefore :-

14 pt = 3.6mm
18 pt = 4.6mm
20 pt = 5.0mm
24 pt = 6.1mm

Depth: Embossed or engraved at 0.5mm is achievable with 1mm giving excellent results. Other sizes can be achieved; however, this is dependent on part geometry and build orientation.

Orientation: Build orientation is best in vertical side walls; however, this is dependent on part geometry and any other critical features in the design. Talk to our CAD experts for advice on how to achieve the best results.
