Rapid prototyping of rapid prototyping machines
Rapid prototyping tools empower individuals to create almost anything. Unfortunately, these tools are still far too expensive for personal ownership. The do-it-yourself community has responded with a slew of home-made rapid prototyping machines, but development times are slow because of the …

Rapid prototyping of green composites
Rapid prototyping employs digital fabrication techniques to quickly manufacture parts. However, the available materials are not yet suitable for making strong, large or durable objects. Composites are materials which are very strong and lightweight, combining the tensile strength of a fibre and the …

Rapid Prototyping Job Scheduling Optimization
Today's commercial rapid prototyping 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 …
