 EXHIBIT 4.3 

RESTRICTED STOCK UNIT AGREEMENT 

AGREEMENT dated as of [Grant Date] between 3D SYSTEMS CORPORATION, a Delaware corporation (the “Company”), and [Name of Recipient]
(the “Participant”). 
 The 2015 Incentive Plan (the “Plan”) of 3D Systems Corporation is designed to assist the Company
and its subsidiaries and affiliates in attracting and retaining employees and consultants of outstanding competence by providing an incentive that permits the persons responsible for the Company’s growth to share directly in that growth and to
further the identity of their interests with the interests of the Company’s stockholders. The Participant is eligible to receive an Award of Restricted Stock Units (“Restricted Stock Units”), each unit of which is a notional
bookkeeping entry representing the equivalent of a share of Common Stock under Section 7 of the Plan. 
 NOW, THEREFORE, the Company
and the Participant mutually agree as follows: 
  

	Section 1.	Restricted Stock Units 

 Subject to the terms and conditions hereinafter set forth, the
Company hereby grants to the Participant and the Participant accepts from the Company [Number of Units] Restricted Stock Units. 
  

	Section 2.	Terms and Conditions of Plan 

 The Participant agrees that all Restricted Stock Units
issued pursuant to this Agreement shall be held in accordance with the terms and conditions of the Plan. The authority of the Company to enter into this Agreement and to issue Restricted Stock Units pursuant hereto is derived exclusively from the
Plan. If any terms or conditions of this Agreement conflict with any terms or conditions of the Plan, the terms and conditions of the Plan shall control. Any capitalized terms not defined herein shall have the meaning assigned to such term in the
Plan. The Participant acknowledges that a copy of the Plan has been made available to the Participant. 
  

	Section 3.	Restriction on Transfer 

 Except as permitted in Section 10 of the Plan, no
Restricted Stock Units issued pursuant to this Agreement, or any interest therein, shall be sold, transferred, pledged, encumbered or otherwise disposed of by the Participant so long as the Participant shall remain a Participant of the Company,
except that such restrictions may expire earlier as provided by Section 9 of the Plan. 








	Section 4.	Forfeiture and Period of Restriction 

 (a) Restricted Stock Units shall be forfeited, and
all rights of the Participant with respect to such Restricted Stock Units shall terminate unless the Participant continues in the service of the Company, a Subsidiary or an Affiliate for a period beginning on the date of the grant and ending on the
earlier of the third anniversary of such date or the date that the Participant’s employment ends on account of death or Disability, and satisfies any and all other conditions set forth in this Agreement. 

(b) Notwithstanding anything contained in Section 7 of the Plan to the contrary, the Compensation Committee of the Board of Directors of
the Company (the “Committee”) may, in its sole discretion, waive the forfeiture period and any other conditions set forth in this Agreement under appropriate circumstances (including, but not limited to, the death, Disability or Retirement
of the Participant or a material change in circumstances arising after the date of an Award) and subject to such terms and conditions (including forfeiture of a proportionate number of the Restricted Stock Units) as the Committee shall deem
appropriate. 
  

	Section 5.	Settlement of Restricted Stock Units 

 Upon expiration or earlier termination of the
restricted period provided in Section 4 above without a forfeiture and the satisfaction of or release from any other conditions set forth in this Agreement, or at such earlier time as provided under Section 4(b) above, the restrictions
applicable to the Restricted Stock Units shall lapse. As promptly as administratively feasible thereafter, subject to the requirements of Section 14 of this Agreement and Section 13 of the Plan (regarding tax withholding), but no later
than sixty (60) days following such event, the Company shall deliver to the Participant or, in case of the Participant’s death, to the Participant’s Beneficiary, (1) a cash payment equal to the number of Restricted Stock Units as
to which such restrictions have lapsed multiplied by the Fair Market Value of a share of Common Stock as of the date the restrictions lapsed, (2) solely in the Committee’s discretion, one or more share certificates registered in the name
of the Participant, for the appropriate number of shares of Common Stock, or a statement from the Company representing that such shares have been issued, are in book entry form and are free of all restrictions, except for any restrictions that may
be imposed by law, or (3) any combination of cash and shares of Common Stock. 
  

	Section 6.	Undertakings of Participant 

 The Participant represents and agrees that he or she will
comply with the Securities Act of 1933, as amended (the “Securities Act”), and the Securities Exchange Act of 1934, as amended (the “Securities Exchange Act”), with respect to such shares, and he or she will indemnify the Company
for any costs, liabilities and expenses that it may sustain by reason of any violation of the Securities Act or the Securities Exchange Act caused by any act or omission on his or her part with respect to such shares.

	Section 7.	Registration of Shares 

 The Company shall use its reasonable commercial efforts to cause
the shares of Common Stock issuable in connection with the Plan to be registered under the Securities Act of 1933, as amended (the “Securities Act”), but shall otherwise be under no obligation to register any shares of Common Stock issued
under the Plan under the Securities Act or otherwise. If, at the time any shares of Common Stock are issued pursuant to the Plan, there shall not be on file with the Securities and Exchange Commission an effective Registration Statement under the
Securities Act covering such shares of Common Stock, the Participant to whom such shares are to be issued will execute and deliver to the Company upon receipt by him or her of any such shares an undertaking, in form and substance satisfactory to the
Company, that (i) such Participant has had access or will, by reason of such person’s employment or service with the Company, or otherwise, have access to sufficient information concerning the Company to enable him or her to evaluate the
merits and risks of the acquisition of shares of the Company’s Common Stock pursuant to the Plan, (ii) such Participant has such knowledge and experience in financial and business matters that such person is capable of evaluating such
acquisition, (iii) it is the intention of such Participant to acquire and hold such shares for investment and not for the resale or distribution thereof, (iv) such Participant will comply with the Securities Act and the Exchange Act with
respect to such shares, and (v) such Participant will indemnify the Company for any cost, liability and expense that the Company may sustain by reason of any violation of the Securities Act or the Exchange Act occasioned by any act or omission
on his or her part with respect to such shares. 
  

	Section 8.	Rights of Holders of Restricted Stock Units 

 (a) Until the lapse or release of the
restrictions applicable to the shares subject to a Restricted Stock Unit, no shares of Common Stock shall be issued in respect of such Restricted Stock Units. Holders of Restricted Stock Units shall not have rights as stockholders of the Company,
with respect to the shares of Common Stock covered by such Restricted Stock Units or otherwise, and shall not have the right to vote such shares or the right to receive dividends until, and then to the extent that, shares of Common Stock are issued
in settlement of the Restricted Stock Units. 
 (b) A holder of Restricted Stock Units shall have no rights other than those of a general
creditor of the Company. Restricted Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of this Agreement.

Common Stock issued pursuant to Restricted Stock Units may bear such restrictive legends and /or appropriate stop-transfer instructions may be issued to the Company’s transfer agent as the Company and the Company’s counsel deem necessary
under applicable law or pursuant to this Agreement.

any receiver, trustee in bankruptcy or representative of creditors of such person. 
  

	Section 13.	Company’s Right to Terminate Retention; Exclusivity 

 Nothing contained in the Plan
shall prevent the Board from adopting other or additional compensation arrangements or modifying existing compensation arrangements for Participants, subject to stockholder approval if such approval is required by applicable statute, rule or
regulation; and such arrangements either may be generally applicable or applicable only in specific cases. Neither the adoption of the Plan nor the issuance of the Restricted Stock Units shall confer upon the Participant any right to continued
employment or service with the Company, a Subsidiary or an Affiliate. 
  

	Section 14.	Payment of Withholding Tax 

 The Participant undertakes to comply with any appropriate
requests that may be made by the Company in respect of the withholding of any federal, state or local taxes and any other charges that may be required by law to be withheld by reason of a grant or the issuance of shares of Common Stock pursuant to
