These font test cards are to investigate which fonts and font sizes are best for extrusion on 3D models. The Arial card is actually Arial Rounded MT Bold. The card with multiple fonts is standardized at 7mm height. Criteria for recommending 3D printer safe fonts; Can the text be read? Do all characters slice properly when at the same scale? Are there any printing artifacts caused by certain characteristics of the font? Can individual character be recognized by touch? Is the font open source or readily available?

Instructions

The Thingiverse community is invited to share examples of the Font Test Cards on various printer models. Please post in the comments which fonts you prefer for extrusion and why. The font card has common "web safe" fonts as a starting point for this investigation.
