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, 2013.
	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, 2014 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 condensed consolidated financial statements and accompanying footnotes have been reclassified to conform to current year presentation.
	All amounts presented in the accompanying footnotes are presented in thousands, except for per share information.
	Recent Accounting Pronouncements
	In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-12, Compensation – Stock Compensation (“ASU 2014-12”). ASU 2014-12 is intended to resolve diverse accounting treatment for share based awards in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 and may be applied prospectively or retrospectively.  The Company does not expect adoption of this standard will have a significant impact on the Company’s consolidated financial statements.
	In August  2014, the FASB  issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements – Going Concern (“ASU 2014-15”). ASU 2014-15 requires an entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern and if those conditions exist, the required disclosures.  The standard is effective for  annual periods ending  after December 15, 2016, and interim periods therein.  The Company does not expect adoption of this standard will have a significant impact on the Company’s consolidated financial statements.
	No other accounting pronouncements, issued or effective during the third quarter of 2014, have had or are expected to have a significant impact on the Company’s consolidated financial statements.

	(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 (loss). 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, 2014  or at December 31, 2013.
	The total impact of foreign currency transactions on the condensed consolidated statements of operations and comprehensive income (loss) for the quarter and nine months ended September 30, 2014 reflected a loss of $1,740 and a loss of $3,085, respectively, compared to a gain of $505 and a loss of $258, respectively, for the quarter and nine months ended September 30, 2013.

	The Company presents basic and diluted earnings per share (“EPS”) amounts. Basic EPS is calculated by dividing net income attributable to 3D Systems Corporation 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	'
	(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, 2014
	(in thousands)		Level 1			Level 2		Level 3		Total
	Description
	Cash equivalents (a)	$	278,800		$	—	$	—	$	278,800
		(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, 2014.
	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, 2014 or December 31, 2013.

	The Company’s effective tax rates were 26.2% and 34.4% for the quarter and nine months ended September 30, 2014, respectively, compared to 31.9% and 30.8% for the quarter and nine months ended September 30, 2013.
	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 2010 to 2013 are subject to examination by the U.S. Internal Revenue Service. The Company has utilized U.S. loss carryforwards causing the years 1997 to 2007 to be subject to examination. The Company files income tax returns (which are open to examination beginning in the year shown in parentheses) in Australia (2009), Belgium (2010), China (2010), France (2011), Germany (2011), India (2012), Israel (2010), Italy (2009), Japan (2007), Korea (2008), Netherlands (2007), Switzerland (2008), and the United Kingdom (2009).

	The Company leases office space under various non-cancelable operating leases. Rent expense under operating leases was $2,763 and $7,673 for the quarter and nine months ended September 30, 2014 compared to $2,122 and $4,940 for the quarter and nine months ended September 30, 2013.
	The Company has supply commitments for printer assemblies that total $55,494 at September 30, 2014, compared to $41,091 at December 31, 2013.
	Certain of the Company’s 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, 2014 and December 31, 2013 was $8,938 and $5,578, respectively.
	Litigation
	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 on 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. On November 8, 2013, the Company voluntarily dismissed the South Carolina complaint and filed a new complaint in the United States District Court for the Southern District of New York asserting that Formlabs’ sales of the Form 1 3D printer infringed on eight of the Company’s patents relating to stereolithography machines.  On December 20, 2013, Formlabs filed a motion to dismiss the Company’s claims of indirect and willful infringement, and the Company filed a memorandum in opposition on January 6, 2014.  Formlabs filed a reply on January 16, 2014. The Court ruled on the motion to dismiss on May 12, 2014, granting in part and dismissing in part Formlabs’ motion. The Company filed a first amended complaint on May 16, 2014, and Formlabs filed its answer on September 2, 2014. The Company intends to pursue claims for damages against Formlabs.
	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 first 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 the Company 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.

Subsequent Event	'
	(18)  Subsequent Event
	On October 10, 2014, the Company and certain of its subsidiaries entered into a $150,000 five-year revolving, unsecured credit facility (the “Credit Agreement”) with PNC Bank, National Association, as Administrative Agent, PNC Capital Markets LLC, as Sole Lead Arranger and Sole Bookrunner, HSBC Bank USA, N.A., as Syndication Agent, and the other lenders party thereto (collectively, the “Lenders”). The Credit Agreement comprises a revolving loan facility that provides for advances in the initial aggregate principal amount of up to $150,000 (the “Credit Facility”).  Subject to certain terms and conditions contained in the Credit Agreement, the Company may, at its option and subject to customary conditions, request an increase in the aggregate principal amount available under the Credit Facility by an additional $75,000.  The Credit Agreement includes provisions for the issuance of letters of credit and swingline loans.
	The Credit Agreement is guaranteed by certain of the Company’s material domestic subsidiaries (the “Guarantors”).  Pursuant to the Credit Agreement, the Guarantors guarantee to the Lenders, among other things, all of the obligations of the Company and each other Guarantor under the Credit Agreement.  From time to time, the Company may be required to cause additional material domestic subsidiaries to become Guarantors under the Credit Agreement.
	Generally, amounts outstanding under the Credit Facility bear interest, at the Company’s option, at either the Base Rate or the LIBOR Rate, in each case, plus an applicable margin.  Base Rate advances bear interest at a rate per annum equal to the sum of (i) the highest of (A) the Administrative Agent’s prime rate, (B) the Federal Funds Open Rate plus 0.5% or (C) the Daily LIBOR Rate for a one month interest period plus 1%, and (ii) an applicable margin that ranges from 0.25% to 0.50% based upon the Company’s consolidated total leverage ratio. LIBOR Rate advances bear interest at a rate based upon the London interbank offered rate for the applicable interest period, plus an applicable margin that ranges from 1.25% to 1.50% based upon the Company’s consolidated total leverage ratio. Under the terms of the Credit Agreement, (i) accrued interest on each loan bearing interest at the Base Rate is payable quarterly in arrears and (ii) accrued interest on each loan bearing interest at the LIBOR Rate is payable in arrears on the earlier of (A) quarterly and (B) the last day of each applicable interest payment date for each loan. The Credit Facility is scheduled to mature on October 10, 2019, at which time all amounts outstanding thereunder will be due and payable.
	The Company is required to pay certain fees in connection with the Credit Facility, including a quarterly commitment fee equal to the product of the amount of the average daily available revolving commitments under the Credit Agreement multiplied by a percentage that ranges from 0.20% to 0.25% depending upon the Company’s leverage ratio, as well as customary administrative fees.
	The Credit Agreement contains customary representations, warranties, covenants and default provisions for a Credit Facility of this type, including, but not limited to, financial covenants, limitations on liens and the incurrence of debt, covenants to preserve corporate existence and comply with laws and covenants regarding the use of proceeds of the Credit Facility. The financial covenants include a maximum consolidated total leverage ratio, which is the ratio of consolidated total funded indebtedness to consolidated EBITDA (earnings before interest, taxes, depreciation and amortization expense), as defined in the Credit Agreement, of 3.00 to 1.00, and a minimum interest coverage ratio, which is the ratio of Consolidated EBITDA to cash interest expense, of 3.50 to 1.0.  The Company is only required to be in compliance with the financial covenants as of the end of any fiscal quarter in which there are any loans outstanding at any time during such fiscal quarter.

	Recent Accounting Pronouncements
	In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-12, Compensation – Stock Compensation (“ASU 2014-12”). ASU 2014-12 is intended to resolve diverse accounting treatment for share based awards in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 and may be applied prospectively or retrospectively.  The Company does not expect adoption of this standard will have a significant impact on the Company’s consolidated financial statements.
	In August  2014, the FASB  issued Accounting Standards Update No. 2014-15, Presentation of Financial Statements – Going Concern (“ASU 2014-15”). ASU 2014-15 requires an entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern and if those conditions exist, the required disclosures.  The standard is effective for  annual periods ending  after December 15, 2016, and interim periods therein.  The Company does not expect adoption of this standard will have a significant impact on the Company’s consolidated financial statements.
	No other accounting pronouncements, issued or effective during the third quarter of 2014, have had or are expected to have a significant impact on the Company’s consolidated financial statements.
