In the opinion of management, the accompanying financial statements reflect all adjustments necessary for a fair presentation of the Company’s statements of financial position, results of operations and cash flows for the periods presented. Except as otherwise disclosed herein, these adjustments consist of normal, recurring items. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures at the date of the financial statements and during the reporting period. Actual results could materially differ from these estimates. For further information, refer to the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the Securities and Exchange Commission (SEC) on February 16, 2024 .

Earnings Per Share [Abstract]
Net Income (Loss) per Common Share	Net Income (Loss) per Common Share Basic net income (loss) per share is computed based on the weighted-average number of common shares outstanding. Diluted net income (loss) per share is computed based on the weighted-average number of common shares outstanding, increased by the number of additional shares that would have been outstanding had potentially dilutive common shares been issued and reduced by the number of shares the Company could have repurchased from the proceeds from issuance of the potentially dilutive shares. Potentially dilutive shares of common stock include stock options and other stock-based awards granted under stock-based compensation plans and shares committed to be purchased under the employee stock purchase plan. Performance stock units are excluded from the calculation of dilutive potential common shares until the performance conditions have been satisfied. Anti-dilutive options were excluded from the calculation of diluted weighted average shares outstanding and were 452,239 and 380,848 for the three months ended June 30, 2024 and 2023 , respectively, and 371,313 and 407,119 for the six months ended June 30, 2024 and 2023, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting Standards Codification, Fair Value Measuremen t (ASC 820), defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy that requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company's assets and liabilities that are required to be measured or disclosed at fair value on a recurring basis include cash and cash equivalents and marketable securities. The Company’s cash consists of bank deposits and cash equivalents consist primarily of money market mutual funds. The Company determines the fair value of these investments using Level 1 inputs. The Company's marketable securities consist of short-term and long-term agency, municipal, corporate and other debt securities. Fair value for the corporate debt securities is primarily determined based on quoted market prices (Level 1). Fair values for the U.S. municipal securities, U.S. government agency securities, certificates of deposit and U.S. treasury securities are primarily determined using dealer quotes or quoted market prices for similar securities (Level 2). The following table summarizes financial assets as of June 30, 2024 and December 31, 2023 measured at fair value on a recurring basis: June 30, 2024 December 31, 2023 (in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Financial Assets: Cash $ 94,871 $ — $ — $ 77,423 $ — $ — Money market mutual fund 1,278 $ — — 6,367 — — Marketable securities 2,465 14,327 — 4,482 22,550 — Total $ 98,614 $ 14,327 $ — $ 88,272 $ 22,550 $ —

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Under the Amended and Restated Proto Labs Inc. 2022 Long-Term Incentive Plan, the Company has the ability to grant stock options, stock appreciation rights (SARs), restricted stock, restricted stock units, other stock-based awards and cash incentive awards, which was approved by the Company's shareholders at a Special Meeting of Shareholders on August 29, 2022 and was amended and restated by the Company's shareholders at its Annual Meeting of Shareholders on May 23, 2024 (as amended and restated, the 2022 Plan) to increase the number of shares available for issuance pursuant to awards under the 2022 Plan by an additional 430,000 shares, add a minimum vesting requirement, and extend the expiration date so that the term of the 2022 Plan runs for ten years from the date of the shareholder approval. Awards under the 2022 Plan have a maximum term of ten years from the date of grant. The compensation committee may provide that the vesting or payment of any award will be subject to the attainment of specified performance measures in addition to the satisfaction of any continued service requirements and the compensation committee will determine whether such measures have been achieved. The per-share exercise price of stock options and SARs granted under the 2022 Plan generally may not be less than the fair market value of a share of our common stock on the date of the grant. The Company also has outstanding awards under the 2012 Long-Term Incentive Plan, as amended (the 2012 Plan), although the plan expired in February 2022 and no additional awards have since been or will be made under the 2012 Plan. The 2012 Plan provided the Company the ability to grant stock options, SARs, restricted stock, restricted stock units, other stock-based awards and cash incentive awards. Awards under the 2012 Plan that subsequently expired, were forfeited or cancelled, or settled in cash after August 29, 2022 became available for awards under the 2022 Plan. Employee Stock Purchase Plan The Company’s 2012 Employee Stock Purchase Plan (ESPP) allows eligible employees to purchase a variable number of shares of the Company’s common stock each offering period at a discount through payroll deductions of up to 15 percent of their eligible compensation, subject to plan limitations. The ESPP provides for six-month offering periods with a single purchase period ending May 15 and November 15, respectively. At the end of each offering period, employees are able to purchase shares at 85 percent of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last trading day of the offering period. Stock-Based Compensation Expense Stock-based compensation expense was $4.2 million and $3.7 million for the three months ended June 30, 2024 and 2023, respectively, and $8.5 million and $7.4 million for the six months ended June 30, 2024 and 2023, respectively.

For employees, options granted become exercisable ratably over the vesting period, which is generally a period of four years, beginning on the first anniversary of the grant date, subject to the employee’s continuing service to the Company. The weighted-average grant date fair value of options that were granted during the six months ended June 30, 2024 was $18.15. The following table provides the assumptions used in the Black-Scholes pricing model valuation of options during the six months ended June 30, 2024 and 2023: Six Months Ended 2024 2023 Risk-free interest rate 4.28% - 4.30% 3.90% - 4.55% Expected life (years) 6.25 2.00 - 6.25 Expected volatility 50.62% - 50.72% 49.23% - 55.92% Expected dividend yield 0% 0% As of June 30, 2024, there was $5.0 million of unrecognized compensation expense related to unvested stock options, which is expected to be recognized over a weighted-average period of 2.9 years.

Performance Stock Performance stock units (PSUs) are expressed in terms of a target number of PSUs, with anywhere between 0 percent and 200 percent of that target number capable of being earned and vesting at the end of a three-year performance period depending on the Company’s performance in the final year of the performance period and the award recipient’s continued employment. Certain PSUs granted by the Company in 2021 are based on performance conditions and the related compensation cost is based on the probability that the performance conditions will be achieved. The Company’s PSUs granted in 2022, 2023, 2024 and certain PSUs granted in 2021 are based on market conditions and the related compensation cost is based on the fair value at grant date calculated using a Monte Carlo pricing model.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is subject to income tax in multiple jurisdictions and the use of estimates is required to determine the provision for income taxes. For the three months ended June 30, 2024 and 2023, the Company recorded an income tax provision of $2.8 million and $2.6 million, respectively. For the six months ended June 30, 2024 and 2023, the Company recorded an income tax provision of $5.3 million and $5.0 million, respectively. The income tax provision is based on the estimated annual effective tax rate for the year applied to pre-tax income. The effective income tax rate for the three months ended June 30, 2024 was 38.3 percent compared to 117.1 percent in the same period of the prior year. The effective tax rate decreased by 78.8 percent for the three months ended June 30, 2024 when compared to the same period in 2023, primarily due to the prior year one-time tax impact of the foreign currency translation loss from the closure of our Japan business. The effective income tax rate for the six months ended June 30, 2024 was 35.0 percent compared to 68.7 percent in the same period of the prior year. The effective tax rate decreased by 33.7 percent for the six months ended June 30, 2024 when compared to the same period in 2023, primarily due to the prior year one-time tax impact of the foreign currency translation loss from the closure of our Japan business. The effective income tax rate for the three and six months ended June 30, 2024 differs from the U.S. federal statutory rate of 21.0 percent due to various factors, including operating in multiple state and foreign jurisdictions partially offset by tax credits for which the Company qualifies.
