EarningsRemember how I wrote on Monday that the PLMish world was quiet, at least as far as acquisitions were concerned? I spoke too soon!

Yesterday we learned of three deals, one in process modeling and two in 3D printing. Neither is an April Fool’s joke, though there were a couple of good ones, like this one from the good folks at John Peddie Research.

First, Aspen Technology announced that it has acquired Sulsim, a sulfur simulation tool from Sulphur Experts. Terms of the transaction were not disclosed. Process plants are required to remove sulfur from their emissions; Sulsim enables process engineers to model both equipment and reactions to make sure that regulations are met. Adding Sulsim to the AspenTech family means that process designers can model cleaning and recovery as well as the plant’s overall operations in a single environment.

Then, Stratasys announced that it will acquire Solid Concepts and Harvest Technologies. Both are additive manufacturing service bureaus — a segment that Stratasys CEO David Reis sees as critical to Stratasys’ success for concept modeling, low-volume and other specialist uses. Stratasys will pay a total consideration of up to $295 million in cash and shares for Solid Concepts. The details of the Harvest Technology were not disclosed but is also payable in cash, shares or a combination of the two.

Solid Concepts is the largest additive services provider in North America, with 6 facilities and 450 employees serving over 5,000 customers; it had revenue of over $65 million in 2013. Harvest is in Belton, TX, and focuses on advanced end-use applications, mostly in aerospace and consumer products. It has 80 employees and 1,000 customers.

Mr. Reis says that “parts sell 3D printers and 3D printers sell parts”. Surveys of Stratasys’ customers show that even those who own a printer often use service bureaus because they have specific process or material needs or face a spike in volume demand. This combination, Stratasys believes, gives it access to a lot of companies that see the benefits of additive manufacturing but may not own printers; too, it lets Stratasys offer services capacity to current 3D printer customers.

Stratasys will combine Solid Concepts and Harvest with its existing RedEye digital manufacturing service business.

Clearly, this changes Stratasys’ revenue and profit picture for 2014, but the company didn’t offer updated guidance during today’s conference call.

Update: Moments after posting this, word came that 3D Systems has acquired  Medical Modeling, a provider of personalized surgical treatments and patient-specific medical devices. What they do sounds really cool; get a sample here.

3D Systems also announced that it will consolidate all of its healthcare activities into a single unit under the leadership of former Medical Modeling President, Andy Christensen, who was named Vice President, Personalized Surgery and Medical Devices.

Terms of the acquisition were not disclosed.
