Re:       Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as special counsel to Desktop Metal, Inc., a Delaware corporation (the “Company”), in connection with the registration of the offer and sale by certain selling securityholders named in the Registration Statement (defined below) of up to 1,557,204 shares (the “Shares”) of Class A common stock, $0.0001 par value per share (the “Common Stock”). The Shares are included in the Registration Statement on Form S-1 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on December 23, 2020, as amended, and as further amended by Post-Effective Amendment No. 1 filed on May 26, 2021 (the “Registration Statement”). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus or prospectus supplement (collectively, the “Prospectus”), other than as expressly stated herein with respect to the issue of the Shares.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are opining herein as to the General Corporation Law of the State of Delaware, and we express no opinion with respect to any other laws.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof the Shares have been duly authorized by all necessary corporate action of the Company and are validly issued, fully paid and nonassessable.
