Purpose This paper aims to investigate the deposited structure and mechanical performance of printed materials obtained during initial development Big Area Additive Manufacturing (BAAM) system at Oak Ridge National Laboratory. Issues unique large-scale polymer deposition are identified presented reduce learning curve for similar systems. Design/methodology/approach Although BAAM’s individual extruded bead is 10-20× larger (∼9 mm) than typical small-scale systems, overall characteristics...
The Big Area Additive Manufacturing (BAAM) system can print structures on the order of several meters at high extrusion rates, thereby having potential to significantly impact automotive, aerospace and energy sectors. functional use such parts, however, may be limited by mechanical anisotropy, in which strength printed parts across successive layers build direction (z-direction) lower than corresponding in-plane (x-y directions). This has been primarily attributed poor bonding between since...
3D printing by fused deposition modeling (FDM) is an advanced additive manufacturing technology for making thermoplastic-based structures. Several studies have recently investigated of polylactic acid (PLA) with biomass resources like cellulose, hemicellulose, lignin and whole biomass. Such biodegradable composites are better the environment can be used to replace non-biodegradable in a variety applications. Therefore, deep understanding such biocomposites needed supporting manufacturing....
Abstract Additive manufacturing allows for the production of complex parts with minimum material waste, offering an effective technique fabricating permanent magnets which frequently involve critical rare earth elements. In this report, we demonstrate a novel method - Big Area Manufacturing (BAAM) to fabricate isotropic near-net-shape NdFeB bonded magnetic and mechanical properties comparable or better than those traditional injection molded magnets. The starting polymer magnet composite...
This article develops a methodology to predict the elastic properties of long-fiber injection-molded thermoplastics (LFTs). The corrected experimental fiber length distribution and predicted orientation distributions were used in modeling compute composite. First, from (FLD) data terms number fibers versus length, probability density functions built computation. two-parameter Weibull's was also represent actual FLD. Next, Mori—Tanaka model that employs Eshelby's equivalent inclusion method...
