3D Systems Surges With Rivals After Canceling at Conference

3D Systems Corp. climbed after canceling a conference appearance, joining an industrywide rally among makers of three-dimensional printers.

3D Systems won’t be able to attend a Pacific Crest Securities conference in August because of management scheduling conflicts, according to an e-mail from Stacey Witten, a representative for the company. 3D Systems had tentatively planned to attend but hadn’t yet confirmed for the event in Vail, Colorado, according to the statement. The cancellation may be stoking takeover speculation, said Angelo Zino, an equity analyst from S&P Capital IQ in New York.
