Text can include words, numbers, punctuation, and other characters. There are many reasons why you may want to add text to your 3D printed part. It may be for branding purposes or to communicate message. In this article, we highlight the three main ways you could add text to your part and the best practices for better results.

 

Embossed Text & Lettering

An embossed text is a text feature raised off the surface of a design. When used right, it creates an eye-catching effect. To ensure that the design is properly visible on the object, it must be designed with a minimum height that adheres to the 3D printer’s capabilities.

Recommended minimum embossed height:

SLA 3D Printing0.3mm
SLS 3D Printing1.0mm
DMLS 3D Printing0.3mm
MJF 3D Printing0.5mm
MJP 3D Printing0.3mm
FDM 3D Printing0.3mm

 

 

Engraved Text & Lettering

Engraved text and lettering is a practical alternative to 3D printing embossed text if you wish to conserve both time and material usage. While embossed details are often easier to see on a model, when done right, engraved text is a great option for adding text onto your part.

 

 

Recommended minimum engraved depth:

SLA 3D Printing0.5mm
SLS 3D Printing1.0mm
DMLS 3D Printing0.5mm
MJF 3D Printing1.0mm
MJP 3D Printing0.5mm
FDM 3D Printing0.5mm

 

 

Tips for Designing Text for 3D Printing. Use a Sans Serif Font like Arial – such fonts tend to be without heavy detailing and will print much clearer. Opt for larger fonts – a safe minimum font size for 3D printed text is font size 14.

Post Processing Options

In many cases, 3D printing a design with text isn’t possible due to visibility issues, design complications or it may even be that the part itself may be too awkwardly shaped for engraving or embossing. In such cases, we can add the text, lettering and symbols during post processing (after the 3D printing process is completed). There are several different ways to do this:

 

  • Laser engraving
  • Silk-screening
  • Pad printing
