Melt electrowriting (MEW) is an electrohydrodynamic process capable of producing organized patterns micrometer-scale polymer fibers. Integrating MEW with other additive manufacturing technologies, such as extrusion-printing or bioprinting, offers tantalizing possibilities for multi-scale biofabrication anatomically shaped scaffolds. However, introducing 3D structures onto the conventionally fla...

Abstract In recent years, the evolution of computer-aided design technology has established a new method to improve digital model creations. The is called Parametric Modeling. this paper, 3D metallic models are printed using novel Modeling approach. goal approach use parametric features simulate and print objects Laser Wire Additive Manufacturing (LWAM) process. proposed includes pattern creati...

With the integration of multiaxis layered manufacturing and material removal (machining) processes, a hybrid system has more capability and flexibility to build complicated geometry with a single setup. Process planning to integrate the two different processes is a key issue. In this paper, an algorithm of adaptive slicing for a five-axis Laser Aided Manufacturing Process (LAMP) is summarized t...

Single point incremental forming is one of the most intensely researched die-less manufacturing process. This process implies usage a CNC equipment or serial robot which deforms sheet metal with help relatively simple tool that follows an imposed toolpath. As every cold process, besides many given advantages it has also some drawbacks. One big drawback in comparison other processes low accuracy...

The three-dimensional (3D) printing technique for cement-based materials has been actively investigated and utilized in civil engineering. However, there is no systematic review of the fabricating devices. This paper reviews software hardware extrusion-based 3D concrete printing. Firstly, a dedicated tool path generating urgently needed to meet cementitious applications improve quality with too...

Abstract This paper explores how small-but–detectable changes in manufacturing protocol can alter interaction-design preferences for users. Building on a number of previous studies by the authors, this focuses manufacture set emotionally attuned pattern-based surface texture designs means computer-numerically controlled (CNC) machining. An experiment is subsequently reported that variations too...

Incremental sheet forming has, despite its great flexibility, not yet been widely adopted by the industry, due to limited geometric accuracy. One of approaches overcome this problem is development closed-loop control systems. Such systems are mostly based on linearization with respect a nominal toolpath. In work, different create such linearized process models reviewed. By implementing in numer...

This paper reports on a dual-axial tool servo diamond turning method for the one-step fabrication of hierarchical micro-nano-structured surfaces. With respect to motion (XZ), z-axis can generate primary surface with complex shape, and x-axis is used synchronously form secondary structure via controlling residual marks. The toolpath determination algorithm developed described in detail, effect m...
