Which 3D Printing Process is Right for You? – The 3D Printed Letter Test

When it comes to choosing the best 3D printing process for a project, print size, print resolution, cost and material capabilities are important to take into consideration. Among the 8 additive manufacturing processes, Fused Filament Fabrication (FFF) is one of the most popular and affordable processes, and often considered as the go-to solution for 3D printing jigs & fixtures, manufacturing aids, functional production parts, etc.

Besides Fused Filament Fabrication (FFF), Selective Laser Sintering (SLS), Polyject and Stereolithography (SLA) are also widely adopted in many industries. Each of these 3D printing processes has its advantages, as well as limitations. Xometry, an additive manufacturing service provider, recently put their FFF, PolyJet and SLS 3D printers to a “3D Printed Letter Test”, the results are very interesting and useful for those who are evaluating the different 3D printing processes.

Xometry’s test results show that with FDM technology, the lettering and spacing are able to stay clear and crisp down to 0.83 mm letter width (Row 3). 3D Platform’s tech team also printed this object on the 3DP Workbench, and as the image shows below, the lettering and spacing are clear and crisp down to 0.67 mm letter width (Row 4). Though some letters are not as crisp as in Row 4, the 0.53 mm letter width (Row 5) still proves to be acceptable.
