Local Adaptive Slicing for Layered Manufacturing
Existing layered manufacturing systems fabricate parts using a constant build layer thickness. Hence, operators must compromise between rapid production with large surface inaccuracies, and slow production with high precision, by choosing between thick and thin build layers, respectively. Adaptive …

Adaptive high-precision exterior, high-speed interior, layered manufacturing
Contemporary layered manufacturing systems build parts using a constant layer thickness. Such systems must seek a compromise between fast fabrication and large inaccuracies on the one hand, and slow fabrication and high precision on the other. This thesis demonstrates how this compromise can be …

Exploring property driven design fabrication through materials testing and software development
Since its introduction in the late 1980s, layered manufacturing has become an increasingly efficient and common means to delivering functional and visually representative prototypes in relatively short amounts of time from previously prepared Computer-Aided Design files. However, most layered …

Integrated process planning for a multi-axis hybrid manufacturing system
"In a multi-axis metal hybrid layered manufacturing system, in which a laser material deposition and material removal system with more than 3-axis mobility are configured, a process planning to automatic define motion path for the integrated system is critical. The purpose of this research is to …

Development of a layerless additive manufacturing stereolithography machine to improve surface quality and dimensional accuracy
Stereolithography (SLA) is an Additive Manufacturing (AM) process that has recently gained significant popularity in manufacturing research. The material used in SLA is a photocurable resin. SLA fabrication has conventionally been executed in a layered build process, which results in the staircase …

Rapid Prototyping Job Scheduling Optimization
… systems (i.e., solid freeform fabrication, layered manufacturing) rely on human intervention to load and unload build jobs. Hence, jobs are processed subject to both the machine's and the operator's schedules. In particular, first-in-first-out (FIFO) queuing of such systems will result in …

Automated Loading and Unloading of the Stratasys FDM 1600 Rapid Prototyping System
… A low-cost auxiliary system, named Continuous Layered Manufacturing (CLM), has been developed to automatically load and unload the FDM 1600 rapid prototyping system (Stratasys, Inc.). The modifications made to the FDM 1600 system are minimal. The door to the FDM 1600 build chamber is removed, …

Towards swarm-based design : distributed and materially-tunable digital fabrication across scales
… between fabrication units. Conventional manufacturing is typically confined to only one of these attribute axes, with certain approaches utilizing complex tunable materials but virtually no collaboration, and others assembling pre-fabricated building blocks with high levels of …
