China3D printingNet July 31st, a new initiative of the U.S. Department of Energy (DoE) Kansas City National Security Campus (KCNSC) is to use3D printingTo increase manufacturing speed and productivity.
In cooperation with Sandia National Laboratory, engineers from the multinational manufacturing group Honeywell are integrating algorithms and 3D simulations to optimize3D printingAnd the design and production of traditional machined parts.
Performed a study comparing work instructions based on 3D models and 2D work instructions, which proved that the3D printingThe entire construction of the wiring assembly operation reduced waste by 15%. By applying work instructions based on 3D models, reducing waste may save millions of dollars through physical prototyping of DoE.
Work instructions based on 3D models. The picture comes from KCNSC.
Partners known as the Simulation First program are using Sandia’s expertise in code development and KCNSC’s simulation applications to improve manufacturing processes that serve the DoE National Nuclear Safety Administration.
In this plan, Honeywell engineers are applying physics-based tools to simulate production operations. This is done to reduce the number of tests required to find the correct process and manufacturing parameters using additive manufacturing and conventionally manufactured components. The optimal weight, structure and robustness are some of the parameters that can be identified using the model before building a prototype.
Speed up the manufacturing process
To prove the function of the Simulation First program, Honeywell’s engineering team produced many foam parts. Due to its complex chemical composition and processing procedures, foam parts usually have low yields and are used for shock-resistant nuclear container parts.
According to this initiative, the KCNSC and Sandia team worked together to find a way to predict the expansion of polyurethane foam in the shell and provide a way to increase production capacity.then
A work instruction based on a 3D model was developed to predict the filling behavior of each package component. Now used on KCNSC more than 400 times, this model has led to the creation of physical prototypes and faster development plans.
Simulation in additive manufacturing
Abandoning the “trial and error” method of product development, the simulation of additive manufacturing has been applied to various industries. Last year, CERN started using Simufact Additive, a digital tool for optimizing laser powder bed fusion (PBF) for predicting SLM 3D printingThe result of this ensures more efficient use of high-value components.
Recently, 3D Systems began to provide its medical simulation solutions through virtual surgery planning (VSP) technology, and its 3D anatomical model series through technology company Stryker. As a result, 3D Systems provided VSP or anatomy services in more than 100,000 cases, including facial reconstruction surgery and full face transplantation.
