Fused filament fabrication (FFF) has been used to create prototypes and functional parts for various applications using plastic filaments. It also extended the use of continuous fibers reinforcing thermoplastic polymers. This study aims optimize deposition design a coextruded carbon fiber (CCF) composite with polyethylene terephthalate glycol?modified (PETG) filament. The characterizations on r...

This study introduces a fused filament fabrication (FFF) process for manufacturing complex-structured asteroid analogue objects to be applied in tomographic microwave radar measurements and inversion studies. We describe an approach control the volume fraction of plastic and, thereby, effective relative permittivity within tetrahedral wireframe which serves as metamaterial representing actual c...

Recycling plastic waste is one way to minimize the negative impact on environment. The use of additive manufacturing which speeds up prototyping process and product design currently uses a 3D printer with ABS PLA filament materials. Remaining filaments unused parts/prototypes, or products that have been manufactured actual materials will be discarded. This causes for recycled 3d printing machin...

The drive towards smart and sustainable manufacturing is leading companies to opt for environmentally conscious technologies. This study assesses the environmental financial feasibility of using additive manufacturing, in this case, fused filament fabrication (FFF), instead injection moulding (IM) mass-produce cosmetic plastic packaging. Using a life cycle assessment (LCA), impacts raw material...

Neuroimaging technologies such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) collect three-dimensional data (3D) that is typically viewed on two-dimensional (2D) screens. Actual 3D models, however, allow interaction with real objects such as implantable electrode grids, potentially improving patient specific neurosurgical planning and personalized clinical education. Desktop ...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...
