}} It was created in March 2013 Defense Distributed printed using the Stratasys Dimension SST 3-D printer[http://defdist.tumblr.com/post/44209819568/printed-ar-lower-v5-review Printed AR Lower v5 Review], Defense Distributed official tumblr blog ([https://web.archive.org/web/20141006141400/http://defdist.tumblr.com/post/44209819568/printed-ar-lower-v5-review archive]) using the fused deposition modeling (FDM) method.

The receiver was able to handle enough stress to fire more than 600 rounds. Defense Distributed stated "actual count of the new SLA lower was 660+ on day 1 with the SLA lower. The test ended when we ran out of ammunition, but this lower could easily withstand 1,000 rounds."[http://www.3ders.org/articles/20130228-3rd-generation-of-3d-printed-ar-lowers-ready-for-download.html 3D printed AR lowers holds up 600+ rounds, file ready for download], 3Ders, Feb 28 2013.
