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...
Abstract The energy transition is one of the main challenges our society and therefore a major driver for scientific community. To ensure smart to sustainable future scenario different technologies such as harvesting using solar cells or windmills chemical storage in batteries, super-capacitors hydrogen have be developed ultimately deployed. New fabrication approaches based on additive manufacturing digitalization industrial processes increase potential achieve highly efficient required...
Experimentation and a survey of the literature clearly show that contact stability in force reflecting teleoperation system requires high levels damping on master robot. However, excessive increases energy required by an operator for commanding motion. The objective this paper is to describe new methodology reduces requirements without sacrificing stability. We begin describing approach modeling identifying remote environment system. combine conventional multi-input, multi-output recursive...
Metal Big Area Additive Manufacturing (MBAAM), an additive manufacturing based on wire-arc process, is progressively evolving from rapid prototyping to the industrial scale production. In MBAAM, height of printed part can easily reach eight feet, and printing last for hours or days. For such large structures, distortion residual stress management are primary challenges in production process. Although transient thermo-mechanical simulations with very small time increments have resulted...
Interest in multi-axis additive manufacturing has grown significantly recent years due to associated benefits that range from improved quality support for greater geometric complexity. A method of 5-axis Laser Hot-Wire Directed Energy Deposition is developed and demonstrated this study using an 8-axis industrial robot, comprised a 6-axis serial link robot 2 degree‐of‐freedom positioner. Coordinated motion used print Ti-6Al-4V objects predominantly through build plate rotation. Methods...
Both mid-wave and long-wave IR cameras are used to measure various temperature profiles in thermoplastic parts as they printed. Two significantly different 3D-printers this study. The first is a small scale commercially available Solidoodle 3 printer, which prints with layer thicknesses on the order of 125μm. second printer "Big Area Additive Manufacturing" (BAAM) 3D-printer developed at Oak Ridge National Laboratory. BAAM 4.06 mm. Of particular interest previously deposited new hot about be...
Big Area Additive Manufacturing (BAAM) is a large-scale, 3D printing technology developed by Oak Ridge National Laboratory's Demonstration Facility and Cincinnati, Inc. The ability to quickly cost-effectively manufacture unique moulds tools currently one of the most significant applications BAAM. This work details application BAAM system fabricate 10.36 m (34 ft) catamaran boat hull mould. goal this project was explore feasibility using directly mould without need for thick coatings. printed...
An extended-range IR camera was used to make temperature measurements of samples as they are being manufactured. The objective is quantify the variation parts fabricated. also map within build volume oven. development oven provides insight into global that may lead understanding variations in properties a function location observation part during construction how deposition process itself creates distributions, which can failure.
