Generate a lattice structure: Many of the parts manufactured through AM have a lattice structure instead of a full continuum.Functional design: The first objective is to generate a suitable design that meets functional requirements, then subsequently improve the design through optimization methodologies that work in parallel with simulation.The role of Simulation in additive manufacturing The ASTM F42 committee is working on defining AM standards with respect to materials, machines, and process variables. The additive manufacturing process is not certifiable yet, which is a major barrier in widespread adoption of these processes commercially.
Distortion: Thermal stresses can lead to distortion that can make the part unusable.These stresses can cause cracks in material during manufacturing. Cracking and failure: The process itself generates lots of heat that produces residual stresses due to thermal expansion.This happens due to material phase change which is typical to most additive manufacturing applications. Change in material properties: Mechanical and thermal properties of a manufactured part differ from raw material properties.Contrary to rapid prototyping and 3D printing, there has been a shift of focus to functional requirements in additive manufacturing however, these functional requirements may deviate from what is expected due to many factors typical of an additive manufacturing process. As a still-evolving technology, it now covers a family of processes such as material extrusion, material jetting, direct energy deposition, power bed fusion, and more.Īdditive manufacturing expands design possibilities by eliminating many manufacturing constraints. Additive manufacturing primarily refers to methods of creating a part or a tool using a layered approach. Stereolithography, a variant of additive manufacturing, was introduced in 1986 for rapid prototyping applications however, its true potential remained hidden for a long time. The 2017 Regional User Meetings are coming up!įor all the information regarding dates, venue, agenda and registrations, please click below.Īdditive manufacturing is not a new technology – it was introduced in the manufacturing industry in late 80s for very niche applications. How big this event could be in terms of public gathering! We try to never miss it because of its size and value a snapshot below from the 2014 event held at Providence, RI speaks for itself.

The new series of events was named the SIMULIA regional user meetings, which are now held at different locations every year: Great Lakes, Houston, California, Toronto, Sao Paulo (Brazil). As its popularity grew, the size of the event grew as well, so there was a need to offer it in multiple locations, making it more accessible to regional users.
Initially this event was called the SIMULIA community conference, with a single location at the North American Headquarters in Rhode Island. As SIMULIA is not so much a product but a portfolio that offers multiple products, SIMULIA regional user meetings are often a conglomeration of various product specific events: Abaqus, Tosca, ISight, Fesafe, Simpack, Simpoe, and the 3DEXPERIENCE platform. There is also an opportunity to present a white paper, listen to keynote speakers about the value simulation brings in virtual product development, get updates on new releases from the SIMULIA product management team, and contribute to this success by being a sponsor of the event. These meetings gather users to share their knowledge and experience in advancing methods and technology for finite element analysis, multi-physics, process automation, design optimization, and simulation management. The regional user meetings organized by SIMULIA once every year have a similar objective: bring together the user community.

In the simulation community, when it’s time to learn applications of software tools in real-life product development, one of the best ways to do it is to approach other users.
