Stratasys Collapse Asks If 3D Printing Boom Has Busted

Summary

Stratasys shares plunged 25% overnight.

The problems were mainly at MakerBot, which represents 12% of sales.

With the speculative fever broken, you can now make an investment decision on the company.

ATP currently up 7%.

ONVO could be interesting today :-

Micro cap Organovo (NYSEMKT:ONVO) is up 10% premarket on average volume in response to its announcement that it presented data on in vitro three-dimensional kidney tissue at the Experimental Biology conference in Boston.

The 3D tissue, fabricated using the company's NovoGen bioprinter, consists of multiple tissue-relevant cell types arranged to recapitulate the renal tubular/interstitial interface, specifically polarized renal proximal tubular epithelial cells and a living interstitial layer of renal fibroblasts and endothelial cells.

Analyzing the tissue on a slide under a microscope showed evidence of formation of microvascular structures and stable maintenance of the layered architecture for at least two weeks.

Organovo (NYSEMKT:ONVO) enters into a multi-year collaboration agreement with Merck (NYSE:MRK) to develop multiple custom tissue models. The deal includes access to
ONVO's exVive3D Human Liver Tissue service. Financial terms are not disclosed.

ONVO is up 17% premarket on robust volume.

Gap closure within sight on ATP.
