3D printing is a process of making three-dimensional solid objects from a digital file process created by laying down successive layers of material until the object is created. Many filaments can be used in 3D printing, one of which is PETG (PolyEthylene ... see more

During the additive manufacturing “boom” of the last decade, consumer level 3D printers have kept pace with commercial/industrial printers, both in numbers and features. However, in material characterization data, the access to date for the consumer has s... see more

3D Printing Machine is a machine that works with the basic principle of CNC, namely the movement of the machine in making the workpiece which is regulated by the G code in 3 coordinate axes x, y, and z. Based on how it works, 3d printing machines are clas... see more

The introduction of bio-composites in the manufacture of tubes by the filament winding technique poses a real challenge for design engineers. This study aims to evaluate the mechanical properties in circumferential traction and in circumferential compress... see more

Processos tecnológicos de manufatura aditiva, como a de impressão 3D, vem permitindo transcender os limites do desenvolvimento dos produtos atuais a um custo menor em de forma mais rápida. Nos últimos anos a impressão 3D se tornou mais fácil de usar e mai... see more

The thermal conditions of a filament LED retro light bulb has been investigated. In such light bulbs, LEDs are mounted on filaments which have glass or sapphire substrate and are surrounded by yttrium-aluminium-garnet (YAG). Heat management is challenging... see more

In this report, we present our results from various studies to qualitatively discriminate the common military explosives viz. RDX, TNT and HMX in their pure form at a distance of ~6.5 m in standoff mode using femtosecond (fs) filament induced breakdown sp... see more

An integral account of design and analysis of grid-stiffened cylindrical structures is presented. For convenience, a two-phase approach is adopted. In the initial phase, with a view to arriving at a few initial possible optimal configurations, parametric ... see more
