I go away for a couple of days, and what happens: merger mania. We’ll dive into a one or two of these in more detail as the week goes on, but here are the high points:

3D Systems acquires a company with the coolest name ever: TIM, The Innovative Modelmakers B.V., a provider of on-demand custom parts services in The Netherlands. TIM will be integrated into DDD’s on-demand parts service and offer its rapid prototyping, model making and manufacturing solutions to design-to-manufacturing professionals and consumers.

Autodesk buys “certain assets” of HSMWorks, until now a SolidWorks CAM partner. Autodesk plans to continue support for SolidWorks customers while integrating “the HSMWorks technology with its industry leading software and cloud services for manufacturing, and will make current HSMWorks products available for purchase and HSMXpress available as a free download.”

Bentley Systems acquired Ivara, a provider of asset performance management software for the asset-intensive mining and metals, oil and gas, petrochemical, power generation and utilities industries. Ivara EXP helps owner-operators boost the performance, reliability, and safety of their assets. Ivara joins Bentley’s line-up of asset management solutions under the AssetWise brand. CEO Greg Bentley said “The Ivara acquisition may be our most significant in years, because it creates an unprecedented opportunity for us to leverage information mobility … [W]ith Ivara we are accelerating information mobility – in terms of the amounts and types of information productively reused – by software innovations ranging from interactive inspections to health modeling, which apply consumer-driven technology advances to ‘industrialized’ projects and environments.”

MSC Software acquires e-Xstream, whose Digimat uses nonlinear micro-mechanics to model materials and physics, including any flaws that may be introduced during their fabriaction. This streamlines failure prediction and enables users to design components so that each part’s material composition is taken into account when designing for critical loads. This appears to dovetail nicely with MSC’s recent announcement about entering into fatigue-related services with HBM-nCode, and will further (as MSC CEO Dominic Gallello says) “blur the boundary between material engineering and structural engineering … helping manufacturers to dramatically reduce the cost of physical testing needed to validate a new material system.”

The Foundry merges with Luxology to improve how “artists produce content”.  According to the FAQ about the merger, everything stays as it is for now — both company names, all associated brands and how customers interacted with each company remain unchanged. Over time, however, it sounds as though Luxology’s modo customers will see expanded support via The Foundry’s wider support network, with staff from both companies. Josh Mings at solidsmack.com has a great interview with Luxology CEO Brad Peebler here with more info.
