Ladies and Gentlemen:

We are currently the principal accountants for voxeljet AG (the “Company”) and under the date of May 7, 2020, we reported on the consolidated financial statements of voxeljet AG and its subsidiaries as of and for the years ended December 31, 2019 and 2018. On January 15, 2020, we were notified that the Company’s Supervisory Board recommended the appointment of PricewaterhouseCoopers GmbH Wirtschaftsprüfungsgesellschaft (“PwC”) to serve as its principal accountant for the year ending December 31, 2020 and that KPMG AG Wirtschaftsprüfungsgesellschaft (“KPMG”) will be dismissed upon completion of the audit of the Company’s consolidated financial statements as of and for the year ended December 31, 2019 and the issuance of our report thereon. We have read the Company statements included under Item 16F on Form 20-F to be filed May 7, 2020, and we agree with such statements, except that we are not in a position to agree or disagree with the Company’s statement that subject to approval at its 2020 Annual General Meeting the Company anticipates that the Audit Committee will appoint PwC. We are also not in a position to agree or disagree with the Company’s statement that PwC was not engaged regarding the application of accounting principles to a specified transaction or the type of audit opinion that might be rendered by PwC on the Company’s consolidated financial statement, or the effectiveness of internal control over financial reporting. Nor are we in a position to agree or disagree with the Company’s statement that PwC did not provide any written or oral advice that was an important factor considered by the Company in reaching a decision as to any such accounting, auditing or financial reporting matter or any matter being the subject of disagreement or defined as a reportable event or any other matter as defined in Item 16F(a)(1)(v) of Form 20-F.

Very truly yours,

/s/ KPMG AG Wirtschaftsprüfungsgesellschaft
