Freeform 3D Printing: Towards a Sustainable Approach to Additive Manufacturing

Most additive manufacturing technologies, such as 3D printing, utilize support materials in the fabrication process. Beyond the technical challenges of support removal, these materials are wasteful – increasing fabrication and processing time while impacting quality. This paper presents “Freeform Printing”, a novel design approach for 3D printing without additional auxiliary structures. A 6-axi...

Implementation of a Lean Model for Carrying out Value Stream Mapping in a Manufacturing Industry

Value Stream Mapping technique involves flowcharting the steps, activities, material flows, communications, and other process elements that are involved with a process or transformation. In this respect, Value stream mapping helps an organization to identify the non-value-adding elements in a targeted process and brings a product or a group of products that use the same resources through the ma...

Navigating towards sustainable development: A system dynamics approach

Traditional fragmented and mechanistic science is unable to cope with issues about sustainability, as these are often related to complex, self-organizing systems. In the paper, sustainable development is seen as an unending process defined neither by fixed goals nor by specific means of achieving them. It is argued that, in order to understand the sources of and the solutions to modern problems...

Sustainable Urban Development with a New Approach to Ethics
