Including Text

The inclusion of text on a plastic 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 and general design guidelines are as follows:

  • Font: For best results we recommend using ARIAL font. Other fonts can be used, but please talk to our CAD experts for advice on whether they would build well on your part.
  • Size: Font size depends upon the orientation of the build, but a good minimum size recommendation is 14 point. Anything less than 8-10 point and it could become difficult to read. As a general guide, 1pt = approx. 0.25mm. Therefore:
    • 14pt = 3.6mm
    • 18pt = 4.6mm
    • 20pt = 5.0mm
    • 24pt = 6.1mm
  • Depth/Height: Embossed or engraved at 0.5mm is achievable and up to 1mm gives excellent results. Other sizes can be achieved, however this is dependent upon part geometry and build orientation.
  • Orientation: Build orientation is best in vertical side walls, however this is dependent upon part geometry and any other critical features in the design. Talk to our CAD experts for advice on how to achieve the best results.
