Autodesk Dreamcatcher Generative Tools Will be Integrated into Netfabb 2018

Netfabb 2018, which has recently stood out as Autodesk‘s comprehensive additive manufacturing solution, will soon be able to combine human ingenuity and machine learning, where the two together are greater than the sum of their parts. The first new service to come to Netfabb is Autodesk Generative Design. After a few years incubating as Project Dreamcatcher in Autodesk’s research group, and coming to life in projects with customers like Airbus and Under Armour, this generative design solution is finally going to be available to mainstream customers.

Autodesk CTO Jeff Kowalski, the strongest supporter of the Dreamcatcher project, called generative design the true embodiment of CAD.  Where for so much of its history, CAD software was more about computer-aided documentation, rather than computer-aided design, CAD packages took the designer’s direction and recorded the lines made by that designer. But with generative design, the computer helps generate design options for the designer’s specified goals.

So how does it work?  Generative design technology takes goals set by a designer or engineer, e.g. size, weight, strength, style, materials, cost, and any number of other criteria, and then uses cloud computing to create a massive number of design solutions.

Using intelligent algorithms based on machine learning and advanced simulation, it produces smart design solutions that can be difficult for today’s designers and engineers to discover and model efficiently. The designer or engineer then identifies and adapts the right solution as desired. This process leads to major reductions in cost, development time, material consumption and product weight and gives our manufacturing customers the ability to design and engineer in brand new ways.

Autodesk Generative Design is not just topology or lattice optimization. While optimization focuses on refining a known solution without any notion of manufacturability, generative design helps the engineer explore a whole cadre of functional and manufacturing design options. With Autodesk Generative Design, a designer or engineer can not only discover a new solution, they can then bring it to life using additive manufacturing tools.Stanley Black & Decker, the hardware and tool maker beloved by consumers and professionals alike, has recently seized on the superpower of generative design. The company’s newly-formed Breakthrough Innovation group started with a pilot project to make one of the tools an electrical line worker uses every day – a hydraulic crimper – better. In this case, better meant lighter. A conventional crimper weighs 15.4lbs and is used hundreds of times in a work shift. But this innovation team couldn’t just use lighter material—the tool still had to be just as strong and durable.

Frank DeSantis, Vice President of the Breakthrough Innovation group, worked with our consulting team to define the desired criteria and insert it into the Autodesk Generative Design service. After examining thousands of combinations of materials and processes, the service generated many options from which the innovation engineers were able to decide on a path forward, satisfied that they had explored all of the options – not just the three or four or even 10 options that engineers may have considered if they used traditional design tools.

The resulting generative design may look a bit unusual to some, but it reduced the hydraulic crimping attachment weight by just over 3lbs, or 60%. The simulations that were run concurrently showed that the tool maintained the strength characteristics of the original tool and, because the generative design service is available for Netfabb users, it also allowed them to create an additive manufacturing strategy to fabricate the new attachment.

By using generative design and additive manufacturing technologies, the Breakthrough Innovation team was able to shave more than three pounds off the crimping tool attachment, reducing the weight by more than 60%.

“The generative design capabilities we can access with Netfabb are almost magical. It’s not brute force engineering. It’s elegant. You define a problem and you get a solution set unlike anything you’d predict. The results of the wire crimper project ensure we’re going to be applying the incredible combination of generative design and additive manufacturing that Netfabb offers to an array of other products we have in development. This is clearly the future and that’s what our Breakthrough Innovation group is all about.” Frank DeSantis, Vice President of the Breakthrough Innovation group at Stanley Black & Decker

Autodesk didn’t just want to expand the innovative designs you can consider when solving complex problems, but also give users greater confidence in their ability to manufacture them. Netfabb 2018 introduces the ability to predict and alter a 3D design to compensate for distortion introduced during the 3D printing process, giving users greater confidence that the part that comes out of the printer will match the design on the screen. There are many other additions to Netfabb 2018. The Autodesk Generative Design technology will be available to current and future Netfabb Ultimate 2018 users later this year.
