FAQs

How fast are 3D printers?

February 19, 2016 By Leslie Langnau Leave a Comment

The answer is it depends. Build speed, as it is used in this blog, refers to how long it can take to build a part as opposed to how fast do the mechanical axes supporting the material deposition nozzle, lasers, DLP system or build plate move. … [Read more...]
