Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On December 28, 2016, the Board of Directors (the “Board”) of 3D Systems Corporation (the “Company”) approved changes to the Company’s Amended and Restated By-Laws, effective immediately (as amended and restated, the “By-Laws”), to implement proxy access.

In response to a proposal received from a stockholder, we engaged in discussions regarding proxy access with a number of our largest stockholders. These conversations allowed us to gain valuable feedback as to the particular proxy access parameters that our stockholders consider appropriate. Based on that feedback and after considering various proxy access provisions adopted by other companies, the Board adopted a proxy access framework that it believes will provide meaningful access for stockholders while safeguarding the long-term interests of the Company and its stockholders and limiting the potential for abuse.

Section 2.13(d) of the By-Laws now permits a stockholder, or a group of up to 20 stockholders, owning 3% or more of the Company’s outstanding common stock continuously for at least three years, to nominate and include in the Company’s annual meeting proxy materials director candidates to occupy up to two or 20% of the Board seats (whichever is greater), provided that such stockholder or group of stockholders satisfies the requirements set forth in Section 2.13(d). Written notice of the nomination(s) must be submitted to the secretary of the Company no earlier than the 150^th day and not later than the 120^th day prior to the anniversary of the date that the Company mailed its proxy statement for the prior year’s annual meeting of stockholders. As a result, proxy access will first be available in connection with the Company’s 2018 annual meeting of stockholders.

The foregoing description of the amendment to the By-Laws does not purport to be complete and is qualified in its entirety by reference to the full text of the By-Laws, a copy of which is attached as Exhibit 3.1 and is incorporated by reference in this Current Report on Form 8-K.
