3D systems reported disappointing Q3 results with sales below consensus expectations due to demand for the company's metal printers that couldn't be manufactured in the quarter, Piper Jaffray analyst Troy Jensen tells investors in a post-earnings research note titled "Another Stumble, Expecting Better Growth in 2019, Reiterate Neutral." Despite the Q3 shortfall, the analyst believes 3D Systems has a "robust pipeline" of new printers that should help drive reaccelerating product growth in 2019. He reiterate a Neutral rating on the shares with a $17 price target.
