Basis Of Presentation [Abstract]
Basis Of Presentation	(1)  Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements include the accounts of 3D Systems Corporation and its subsidiaries (collectively, the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim reports. Accordingly, they do not include all the information and notes required by GAAP for complete financial statements and should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the year ended December 31, 2012.
	In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments, consisting of adjustments of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The results of operations for the quarter and nine months ended September 30, 2013 are not necessarily indicative of the results to be expected for the full year.
	The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from those estimates and assumptions.
	Certain prior period amounts presented in the accompanying footnotes have been reclassified to conform to current year presentation.
	The Company’s Board of Directors approved a three-for-two stock split, effected in the form of a 50% stock dividend, which was paid on February 22, 2013 to stockholders of record at the close of business on February 15, 2013. The Company’s stockholders received one additional share of common stock for every two shares of common stock owned. This did not change the proportionate interest that a stockholder maintained in the Company. In lieu of fractional shares, shareholders received a cash payment based on the closing market price of DDD stock on the record date. All share and per share amounts set forth in this report, including earnings per share and the weighted average number of shares outstanding for basic and diluted earnings per share, for each respective period, have been adjusted to reflect the three-for-two stock split.
	All amounts presented in the accompanying footnotes are presented in thousands, except for per share information.
	Recent Accounting Pronouncements
	No new accounting pronouncements, issued or effective during the third quarter of 2013, have had or are expected to have a significant impact on the Company’s consolidated financial statements.

Acquisitions [Abstract]
Acquisitions	(2) Acquisitions
	The Company completed four acquisitions in the third quarter of 2013, which are discussed below. During the previous quarters of 2013, the Company completed three acquisitions which aggregated to a purchase price of $97,449.
	On July 15, 2013, the Company acquired approximately 82% of the outstanding shares and voting rights of Phenix Systems, a leading global provider of direct metal selective laser sintering 3D Printers based in Riom, France. Phenix Systems designs, manufactures and sells proprietary direct metal 3D printers that can print chemically pure, fully dense metal and ceramic parts from very fine powders. The fair value of the consideration paid for this acquisition, net of cash acquired, was approximately $14,561 based on the exchange rate at the date of acquisition, all of which was paid in cash. Phenix’s operations have been integrated into printers and other products and services revenue.  Factors considered in determination of goodwill include synergies, workforce, vertical integration and strategic fit for the Company.
	On August 6, 2013, the Company acquired VisPower Technology, Inc., a cloud-based, collaborative design and project management platform (“TeamPlatform”). The fair value of the consideration paid for this acquisition, net of cash acquired, was $4,998, all of which was paid in cash. TeamPlatform’s operations have been integrated into the Company’s professional and consumer offerings, including Geomagic Solutions and Cubify.com. Factors considered in determination of goodwill include synergies, workforce, vertical integration and strategic fit for the Company.
	On August 20, 2013, the Company acquired CRDM, Ltd. (“CRDM”), a U.K. provider of rapid prototyping and rapid tooling services. The fair value of the consideration paid for this acquisition, net of cash acquired, was approximately $6,399 based on the exchange rate at the date of acquisition, all of which was paid in cash. CRDM’s operations have been integrated into the Company’s global Quickparts Solutions custom parts and manufacturing services revenue. Factors considered in determination of goodwill include synergies, workforce, vertical integration and strategic fit for the Company.
	On September 6, 2013, the Company acquired The Sugar Lab, a  start-up micro-design firm based in Los Angeles, California, that is dedicated to 3D printing customized, multi-dimensional, edible confections. The fair value of the consideration paid for this acquisition, net of cash acquired, was $1,500, of which $1,000 was paid in cash and $500 was paid in shares of the Company’s stock. These shares were issued in a private transaction exempt from registration under the Securities Act of 1933. The Sugar Lab’s operations have been integrated into the Company’s printers and services revenue. Factors considered in determination of goodwill include synergies, vertical integration and strategic fit for the Company.
	The acquisitions completed in the third quarter are not material relative to the Company’s assets or operating results; therefore, no proforma financial information is provided.
	The Company’s purchase price allocation for the acquired companies is preliminary and subject to revision as more detailed analyses are completed and additional information about fair value of assets and liabilities becomes available. The amounts related to the third quarter acquisitions are allocated to the assets acquired and the liabilities assumed and are included in the Company’s condensed consolidated balance sheet at September 30, 2013 as follows:

Hedging Activities And Financial Instruments [Abstract]
Hedging Activities And Financial Instruments	(7)  Hedging Activities and Financial Instruments
	The Company conducts business in various countries using both the functional currencies of those countries and other currencies to effect cross border transactions. As a result, the Company is subject to the risk that fluctuations in foreign exchange rates between the dates that those transactions are entered into and their respective settlement dates will result in a foreign exchange gain or loss. When practicable, the Company endeavors to match assets and liabilities in the same currency on its balance sheet and those of its subsidiaries in order to reduce these risks. When appropriate, the Company enters into foreign currency contracts to hedge exposures arising from those transactions. The Company has elected not to prepare and maintain the documentation to qualify for hedge accounting treatment under ASC 815, “Derivatives and Hedging,” and therefore, all gains and losses (realized or unrealized) are recognized in "Interest and other expense, net”  in the condensed consolidated statements of operations and comprehensive income. Depending on their fair value at the end of the reporting period, derivatives are recorded either in prepaid expenses and other current assets or in accrued liabilities on the condensed consolidated balance sheet.
	There were no foreign currency contracts outstanding at September 30, 2013  or at December 31, 2012.
	The total impact of foreign currency transactions on the condensed consolidated statements of operations and comprehensive income for the quarter and nine months ended September 30, 2013 reflected a gain of $505 and a loss of $258, respectively, compared to a gain of $653 and a gain of  $138, respectively, for the quarter and nine months ended September 30, 2012.

	5.5% senior convertible notes and interest expense
	In November 2011, the Company issued $152,000 of 5.50% senior convertible notes due December 2016.  These notes are senior unsecured obligations and rank equal in right of payment with all the Company’s existing and future senior unsecured indebtedness.  They are also senior in right of payment to any subordinated indebtedness that the Company may incur in the future.
	The notes accrue interest at the rate of 5.50% per year payable in cash semi-annually on June 15 and December 15 of each year.
	The following table summarizes the principal amounts and related unamortized discount on convertible notes at September 30, 2013 and December 31, 2012:
	(in thousands)	2013		2012
	Principal amount of convertible notes	$	12,540	$	90,960
	Unamortized discount on convertible notes		-1,205		-10,429
	Net carrying value	$	11,335	$	80,531
	These notes are convertible into shares of the Company’s Common Stock at a conversion rate equivalent to 69.9032 shares of Common Stock per $1 principal amount of notes, which represents a conversion rate of approximately $14.31 per share of Common Stock.  The conversion rate is subject to adjustment in certain circumstances as more fully set forth in the indenture covering the notes.  Conditions for conversion have been satisfied and the notes are convertible. During the third quarter of 2013 note holders converted $15,000 aggregate principal amount of notes, which converted into 1,049 shares of common stock, on a split-adjusted basis. The Company recognized a $2,022 loss on conversion of these notes in interest and other expense, net. During the first nine months of 2013, note holders converted $78,420 aggregate principal amount of notes, which converted into 5,482 shares of common stock, on a split-adjusted basis. The Company recognized a $11,275 loss on conversion of these notes in interest and other expense, net.
	The remaining notes are convertible into approximately 876 shares of common stock. In certain circumstances provided for in the indenture, the number of shares of common stock issuable upon conversion of the notes may be increased, and with it the aggregate principal amount of the notes. Unless earlier repurchased or converted, the notes will mature on December 15, 2016.
	The notes were issued with an effective yield of 5.96% based upon an original issue discount at 98.0%.  The net proceeds from the issuance of these notes, after deducting original issue discount and capitalized issuance costs of $6,634, amounted to $145,366. The capitalized issuance costs are being amortized to interest expense over the life of the notes, or realized upon conversion of the notes.
	Upon certain terms and conditions, the Company may elect to satisfy its conversion obligation with respect to the notes by paying cash, in whole or in part, for specified aggregate principal amount of the notes. In the event of certain types of fundamental changes, the Company will increase the conversion rate by a number of additional shares, up to a maximum of 1,118 shares, which equates to a conversion price of approximately $11.22 per share.

Earnings Per Share	(11)  Earnings Per Share
	The Company presents basic and diluted earnings per share (“EPS”) amounts. Basic EPS is calculated by dividing net income  available to common stockholders by the weighted average number of common shares outstanding during the applicable period. Diluted EPS is calculated by dividing net income by the weighted average number of common and common equivalent shares outstanding during the applicable period.

Fair Value Measurements [Abstract]
Fair Value Measurements	(12)  Fair Value Measurements
	ASC 820, “Fair Value Measurements and Disclosures,” 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 which requires an entity to maximize the use of observable 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; or
	·	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.
	For the Company, the above standard applies to cash equivalents and senior convertible notes. The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
	Assets and liabilities measured at fair value on a recurring basis are summarized below:
		Fair Value Measurements as of September 30, 2013
	(in thousands)		Level 1		Level 2		Level 3		Total
	Description
	Cash equivalents (a)	$	289,219	$	—	$	—	$	289,219
	(a)	Cash equivalents include funds held in money market instruments and are reported at their current carrying value, which approximates fair value due to the short-term nature of these instruments and are included in cash and cash equivalents in the consolidated balance sheet.
	The Company did not have any transfers of assets and liabilities between Level 1 and Level 2 of the fair value measurement hierarchy during the quarter and nine months ended September 30, 2013.
	The carrying value of the senior convertible notes as of September 30, 2013 and December 31, 2012 was $11,335 and $80,531, respectively, net of the unamortized discount. As of September 30, 2013 and December 31, 2012, the estimated fair value of the senior convertible notes was $12,188 and $86,981, respectively, based on quoted market prices. The Company determined the fair value of the convertible notes utilizing transactions in the listed markets for identical or similar liabilities. As such, the fair value of the senior convertible notes is considered Level 2.
	In addition to the financial assets included in the above table, certain of our non-financial assets and liabilities are to be initially measured at fair value on a non-recurring basis. This includes items such as non-financial assets and liabilities initially measured at fair value in a business combination (but not measured at fair value in subsequent periods) and non-financial, long-lived assets measured at fair value for an impairment assessment. In general, non-financial assets and liabilities including goodwill, other intangible assets and property and equipment are measured at fair value when there is an indication of impairment and are recorded at fair value only when impairment is recognized. The Company has not recorded any impairments related to such assets and has had no other significant non-financial assets or non-financial liabilities requiring adjustments or write-downs to fair value as of September 30, 2013 or December 31, 2012.

	The Company’s effective tax rates were 31.9% and 30.8% for the quarter and nine months ended September 30, 2013, respectively, compared to 16.9% and 17.1% for the quarter and nine months ended September 30, 2012.
	The Company has not provided for any taxes on the unremitted earnings of its foreign subsidiaries, as the Company intends to permanently reinvest all such earnings outside of the U.S. We believe a calculation of the deferred tax liability associated with these undistributed earnings is impracticable.
	Tax years 2009 to 2012 remain subject to examination by the U.S. Internal Revenue Service. The Company has utilized U.S. loss carryforwards incurred during the 1997-2008 period and these years are subject to examination. The Company files income tax returns (which are open to examination beginning in the year shown in parentheses) in France (2006), Germany (2006), Japan (2007), Korea (2010), Italy (2007), Switzerland (2007), the United Kingdom (2009), the Netherlands (2007), India (2012), China (2013) and Australia (2008).

	The Company has supply commitments with third party assemblers for printer assemblies that total $17,613 at September 30, 2013, compared to $10,894 at December 31, 2012.
	For certain of the acquisitions, the Company is obligated for deferred purchase price commitments. At September 30, 2013, these commitments total $5,980, which are due through 2014, compared to obligations of $1,465 at December 31, 2012. Certain of the Company’s recent acquisitions contain earnout provisions under which the sellers of the acquired businesses can earn additional amounts. The total liabilities recorded for these earnouts as of September 30, 2013 and December 31, 2012 was $2,016 and $2,647, respectively. See Note 2 for details of acquisitions and related commitments.
	Litigation
	In 2008, DSM Desotech Inc. filed a complaint, which it has subsequently amended, in an action titled DSM Desotech Inc. v. 3D Systems Corporation and 3D Systems, Inc. in the United States District Court for the Northern District of Illinois (Eastern Division) asserting that the Company engaged in anticompetitive behavior with respect to resins used in certain of its stereolithography machines. The complaint further asserted that the Company is infringing upon two of DSM Desotech’s patents relating to stereolithography machines.
	On January 31, 2013, the Court granted the Company summary judgment for all seven of the counts alleging anticompetitive behavior. On February 28, 2013, the parties filed a stipulation of dismissal of the remaining counts, and the Court dismissed those counts in connection with the settlement of these portions of the litigation. On March 29, 2013, DSM Desotech filed a notice of appeal to the United States Court of Appeals for the Federal Circuit regarding the Court’s granting of summary judgment in favor of the Company on all seven counts of alleged anticompetitive behavior. DSM Desotech filed its opening appellate brief on May 28, 2013. The Company filed its response appellate brief on July 11, 2013 and DSM Desotech filed its reply appellate brief on August 12, 2013. The Company intends to continue to vigorously contest all the claims asserted by DSM Desotech.
	On November 20, 2012, the Company filed a complaint in an action titled 3D Systems, Inc. v. Formlabs, Inc. and Kickstarter, Inc. in the United States District Court for the District of South Carolina (Rock Hill Division) asserting that Formlabs’ and Kickstarter’s sales of the Form 1 3D printer infringed one of the Company’s patents relating to stereolithography machines. Formlabs and Kickstarter filed a motion to dismiss or transfer venue on February 25, 2013, and the Company filed a first amended complaint on March 8, 2013. On May 8, 2013, the Court granted the parties’ joint motion to stay the case until September 3, 2013 to enable the parties to continue settlement discussions. No settlement has been reached and the Company intends to pursue claims for damages against Formlabs and Kickstarter.
	The Company is also involved in various other legal matters incidental to its business. The Company believes, after consulting with counsel, that the disposition of these other legal matters will not have a material effect on our consolidated results of operations or consolidated financial position.
	Indemnification
	In the normal course of business the Company periodically enters into agreements to indemnify customers or suppliers against claims of intellectual property infringement made by third parties arising from the use of the Company’s products. Historically, costs related to these indemnification provisions have not been significant and we are unable to estimate the maximum potential impact of these indemnification provisions on our future results of operations.
	To the extent permitted under Delaware law, the Company indemnifies directors and officers for certain events or occurrences while the director or officer is, or was serving, at the Company’s request in such capacity, subject to limited exceptions. The maximum potential amount of future payments we could be required to make under these indemnification obligations is unlimited; however, the Company has directors and officers insurance coverage that may enable the Company to recover future amounts paid, subject to a deductible and the policy limits. There is no assurance that the policy limits will be sufficient to cover all damages, if any.

Basis Of Presentation [Abstract]
Description of stock split		The Company's Board of Directors approved a three-for-two stock split, effected in the form of a 50% stock dividend, which was paid on February 22, 2013 to stockholders of record at the close of business on February 15, 2013. The Company's stockholders received one additional share of common stock for every two shares of common stock owned. This did not change the proportionate interest that a stockholder maintained in the Company. In lieu of fractional shares, shareholders received a cash payment based on the closing market price of DDD stock on the record date. All share and per share amounts set forth in this report, including earnings per share and the weighted average number of shares outstanding for basic and diluted earnings per share, for each respective period, have been adjusted to reflect the three-for-two stock split.
