Significant Accounting Policies [Text Block]	Note 2 — Summary of Significant Accounting Policies Principles of consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, as listed within “Organization and business” above. All intercompany accounts and transactions have been eliminated in consolidation. Comprehensive income Components of comprehensive income include net income and foreign currency translation adjustments. Comprehensive income is disclosed in the accompanying consolidated statements of comprehensive income and consolidated statements of shareholders’ equity. Accounting estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and cash equivalents Cash and cash equivalents include cash and other investments, including marketable securities, with maturities of three months or less at the date of purchase. The Company maintains its cash in bank deposit accounts, which, at times, may exceed federally insured limits. The Company has not experienced any losses on such accounts. Marketable securities Marketable securities include held-to-maturity debt securities recorded at amortized cost. Management determines the appropriate classification of debt securities at the time of purchase and reevaluates such designation as of each balance sheet date. Debt securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost, adjusted for amortization of premiums and accretion of discounts to maturity computed under the effective interest method. Such amortization is included in other income, net. Interest on securities classified as held to maturity is included in other income, net. The classification of marketable securities as current or non-current is dependent upon the security’s maturity date. Securities with maturities of three months or less at the time of purchase are categorized as cash equivalents as described above. The Company reviews impairments associated with its marketable securities in accordance with the measurement guidance provided by ASC 320, Investments – Debt and Equity Securities, when determining the classification of impairment as “temporary” or “other-than-temporary.” The factors used to differentiate between temporary and other-than-temporary include assessment of the quality of the security, credit ratings actions and management’s intent to hold the security to maturity as well as other factors. Accounts receivable and allowance for doubtful accounts Accounts receivable are reported at the invoiced amount less an allowance for doubtful accounts. As of each balance sheet date, the Company evaluates its accounts receivable and establishes an allowance for doubtful accounts based on a combination of specific customer circumstances and credit conditions taking into account the history of write-offs and collections. A receivable is considered past due if payment has not been received within the period agreed upon in the invoice. Accounts receivable are written off after all collection efforts have been exhausted. Recoveries of trade receivables previously written off are recorded when received. Inventory Inventory consists primarily of raw materials, which are recorded at the lower of cost or market, using the average cost method, which approximates first-in, first-out (FIFO) cost. The Company periodically reviews its inventory for slow-moving, damaged and discontinued items and provides allowances to reduce such items identified to their recoverable amounts. Property, equipment and leasehold improvements Property, equipment and leasehold improvements are stated at cost. Major improvements that substantially extend an asset’s useful life are capitalized. Repairs, maintenance and minor improvements are charged to operations as incurred. Depreciation, including amortization of leasehold improvements and assets recorded under capital leases, is calculated using the straight-line method over the estimated useful lives of the individual assets and ranges from 3 to 39 years. Manufacturing equipment is depreciated over 3 to 15 years, office furniture and equipment are depreciated over 3 to 7 years, computer hardware and software are depreciated over 3 to 5 years, building costs are depreciated over 39 years, leasehold improvements are depreciated over the estimated lives of the related assets or the life of the lease, whichever is shorter, and building and land improvements are depreciated over 10 to 39 years. Assets not in service are not depreciated until the asset is put into use. The Company follows ASC 350-40, Internal-Use Software, in accounting for internally developed software. As of December 31, 2019 and 2018, respectively, $32.7 million and $16.6 million of software development costs were capitalized. Capitalized software development costs for the year ended December 31, 2019 were $16.1 million. Goodwill The Company recognizes goodwill in accordance with ASC 350, Intangibles—Goodwill and Other. Goodwill is the excess of cost of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. Goodwill is tested for impairment annually in the fourth quarter of each year, and is tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired. An impairment charge for goodwill is recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying amount. Other Intangible Assets Other intangible assets include software technology, customer relationships and other intangible assets acquired from other independent parties. Other intangible assets with a definite life are amortized over a period ranging from two to 10 years on a straight line basis, and are tested for impairment whenever events or circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows generated by the asset. The amount of the impairment loss recorded is calculated by the excess of the asset’s carrying value over its fair value. Accounting for long-lived assets The Company periodically reviews the carrying amount of its property, equipment and leasehold improvements to determine if circumstances exist indicating an impairment or if depreciation periods should be modified. If facts or circumstances indicate that an impairment may exist, the Company will prepare a projection of the undiscounted future cash flows of the specific assets to determine if the assets are recoverable. If impairment exists based on these projections, an adjustment will be made to reduce the carrying amount of the specific assets to fair value. Revenue recognition On January 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers, using the modified retrospective approach. The Company manufactures custom parts to specific customer orders that have no alternative use to the Company, and the Company believes there is a legally enforceable right to payment for performance completed to date on these manufactured parts. For manufactured parts that meet these two criteria, the Company will recognize revenue over time. Revenue is recognized over time using the input method based on time in production as a percentage of total estimated production time to measure progress toward satisfying performance obligations. Prior to 2018, the Company recognized revenue when it was realized or realizable and earned when all of the following criteria were met: persuasive evidence of an arrangement existed, delivery had occurred or services had been rendered, the price to the buyer was fixed or determinable and collectability was reasonably assured. Revenue was recognized upon transfer of title and risk of loss, which was generally upon the shipment of parts in the Company’s Injection Molding, CNC Machining, 3D Printing and Sheet Metal product lines. Leases On January 1, 2019, the Company adopted ASC 842, Leases, which introduced the balance sheet recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease assets, current operating lease liabilities and long-term operating lease liabilities in the Consolidated Balance Sheets and are recognized based on the present value of lease payments over the lease term at commencement date. Income taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes (ASC 740). Under this method, the Company determines tax assets and liabilities based upon the differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. The tax consequences of most events recognized in the financial statements are included in determining income taxes currently payable. However, because tax laws and financial accounting standards differ in their recognition and measurement of assets, liabilities and equity, revenues, expenses, gains and losses, differences arise between the amount of taxable income and pretax financial income for a year and between the tax basis of assets or liabilities and their reported amounts in the financial statements. Because the Company assumes that the reported amounts of assets and liabilities will be recovered and settled, respectively, a difference between the tax basis of an asset or liability and its reported amount in the balance sheet will result in a taxable or a deductible amount in some future years when the related liabilities are settled or the reported amounts of the assets are recovered, giving rise to a deferred tax asset or liability. The Company establishes a valuation allowance for any portion of its deferred tax assets that the Company believes may not be recognized. ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements by requiring that individual tax positions are recorded only when they meet a more-likely-than-not criterion. Additionally, ASC 740 provides guidance on measurement, de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Stock-based compensation The Company accounts for stock-based compensation in accordance with ASC 718, Compensation—Stock Compensation (ASC 718). Under the fair value recognition provisions of ASC 718, the Company measures stock-based compensation cost at the grant date fair value and recognizes the compensation expense over the requisite service period, which is the vesting period, using a straight-line attribution method. The amount of stock-based compensation expense recognized during a period is based on the portion of the awards that are ultimately expected to vest. The Company accounts for forfeitures as they occur. Ultimately, the total expense recognized over the vesting period will only be for those awards that vest. The Company’s awards are not eligible to vest early in the event of retirement, however, the awards vest early in the event of a change in control. In determining the compensation cost of the options granted, the fair value of options granted has been estimated on the date of grant using the Black-Scholes option-pricing model. Advertising costs Advertising is expensed as incurred and was approximately $13.0 million, $11.8 million and $10.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. Research and development Research and development expenses consist primarily of personnel and outside service costs related to the development of new processes and product lines, enhancements of existing product lines, development of software for internal use, maintenance of internally developed software, quality assurance and testing. Costs for internal use software are evaluated by project and capitalized where appropriate under ASC 350-40, Intangibles - Goodwill and Other, Internal-Use Software. Research and development costs were approximately $32.7 million, $28.7 million and $23.6 million for the years ended December 31, 2019, 2018 and 2017, respectively. Foreign currency translation/transactions The Company translated the balance sheets of its foreign subsidiaries at period-end exchange rates and the income statement at the average exchange rates in effect throughout the period. The Company has recorded the translation adjustment as a separate component of consolidated shareholders’ equity. Foreign currency transaction gains and losses are recognized in the consolidated statements of comprehensive income. Business combinations The Company accounts for business combinations in accordance with ASC 805, Business Combinations (ASC 805). On November 30, 2017, the Company acquired RAPID Manufacturing Group, LLC (RAPID) for $122.0 million, consisting of $110.6 million in cash and $11.3 million in the Company’s common stock. Recently adopted accounting pronouncements During the fourth quarter of 2019, the Company early adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2017-04, Intangibles – Goodwill and Other, which is intended to simplify the subsequent measurement of goodwill. The adoption of this guidance had no material impact on the Company's consolidated financial statements. During the first quarter of 2019, the Company adopted the FASB ASU 2016-02, Leases (ASC 842), which introduces the balance sheet recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The Company has adopted the new lease standard using the new transition option issued under the amendments in ASU 2018-11, Leases, which allowed the Company to continue to apply the legacy guidance in Accounting Standards Codification (ASC) 840, Leases, in the comparative periods presented in the year of adoption. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. The Company made an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. The Company will recognize those lease payments in the Consolidated Statements of Comprehensive Income on a straight-line basis over the lease term. The impact of the adoption was an increase to the Company’s operating lease assets and liabilities on January 1, 2019 of $13.1 million. During the first quarter of 2018, the Company adopted the FASB ASU 2014-09, Revenue from Contracts with Customers (ASC 606). This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue from the transfer of goods or services to customers in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. The Company adopted the new revenue standard using the modified retrospective approach. The Company manufactures custom parts to specific customer orders that have no alternative use to the Company, and the Company believes there is a legally enforceable right to payment for performance completed to date on these manufactured parts. For manufactured parts that meet these two criteria, the Company will recognize revenue over time. The transition adjustment recorded was an increase of $1.5 million to the Company's retained earnings balance as of January 1, 2018. During the first quarter of 2018, the Company adopted ASU 2017-09, Compensation – Stock Compensation, which is intended to provide clarity and reduce diversity in practice as well as cost and complexity when applying the guidance to a change to the terms or conditions of a share-based payment award. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. Recently issued accounting pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes, which is intended to simplify the accounting for income taxes. This guidance will be effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years with early adoption permitted. The Company is evaluating the impact of future adoption of this guidance on its consolidated financial statements, but does not expect the impact to be material. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses, which is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments held by a reporting entity at each reporting date. This guidance will be effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years with early adoption permitted. The impact of this guidance will not have a material impact on the Company's consolidated financial statements.

Foreign currency transaction gains and losses are recognized in the consolidated statements of comprehensive income.

Business combinations

The Company accounts for business combinations in accordance with ASC 805, Business Combinations (ASC 805). On November 30, 2017, the Company acquired RAPID Manufacturing Group, LLC (RAPID) for $122.0 million, consisting of $110.6 million in cash and $11.3 million in the Company’s common stock.

Recently adopted accounting pronouncements

During the fourth quarter of 2019, the Company early adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2017-04, Intangibles – Goodwill and Other, which is intended to simplify the subsequent measurement of goodwill. The adoption of this guidance had no material impact on the Company's consolidated financial statements.

During the first quarter of 2019, the Company adopted the FASB ASU 2016-02, Leases (ASC 842), which introduces the balance sheet recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance.

The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

Recently issued accounting pronouncements

In December 2019, the FASB issued ASU 2019-12, Income Taxes, which is intended to simplify the accounting for income taxes. This guidance will be effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years with early adoption permitted. The Company is evaluating the impact of future adoption of this guidance on its consolidated financial statements, but does not expect the impact to be material.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses, which is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments held by a reporting entity at each reporting date. This guidance will be effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years with early adoption permitted.
