Go to the web site for the SEC - it's sec.gov - and hover your cursor over the "Filings" menu item toward the top right. From the resulting menu, choose "company filings search" and then on the resulting page enter "Stratasys Ltd". If you just enter "Stratasys" you'll get 2 listings, one for the pre-merger company and one for the post-merger company based in Israel. The search result will list all of the filings. The items you are looking for are the form 20-F dated 2013-03-07 and the form 6-K dated 2013-05-13 (there are 2 forms 6-K filed on that date, you want the one with the "Interactive Data" button next to it).
