Shares fell 23.2% to $8.12.

Revenue in the quarter was $152 million, down 8% from year-earlier revenue of $165.9 million. Analysts surveyed by FactSet had been looking for revenue of  $164.69 million.

The company reported a non-GAAP loss of 9 cents a share, much wider than expectations that called for a loss of 1 cent.

Canaccord Genuity has a hold rating on the stock and lowered its price target to $10 from $13.

The company's transition from plastic-based printers to metal-based ones has "been rough and at a slow pace," the analyst said. Metal printing margins are lower than plastic.

William Blair, who has an underperform rating on the stock, is concerned with cash burn in the near term and said even at $9 the stock would be overvalued.
