NEW YORK (TheStreet) -- ExOne  (XONE) tumbled 11.43% to $39.61, down $5.11 from its previous close of $44.72, at the close of the trading day on Wednesday after 3D Systems (DDD) significantly lowered its profit estimates for 2013, which again brought about fears of a bubble in the 3D printing industry.

3D Systems lowered its estimates to a range of 83 to 87 cents a share from a range of 93 cents to $1.03 a share. It cited greater spending on research, manufacturing and marketing as the reasons for the reduction. The company also forecast guidance for 2014 that was less than analysts' estimates.

ExOne's stock hit a low of $37.80 on Wednesday. It had a volume of 1,390,503, more than double its average of 690,032.
