RAPID prototyping, MANUFACTURING processes, MACHINING, SCARCITY, and MATERIALS
This contribution starts by observing the low presence of "indie made", distributed and digital fabrication based products in the everyday life of most people. We assume that this low presence is a result of limitations regarding the available physical behaviors, achievable functionalities, and accessible market, all of which can be optimized to the extreme with mass manufacturing. The paper explores possible design strategies to compensate these three key shortages of indie manufacturing for everyday life, aiming at better materials, more advanced functional "machines", as well as alternative ways of creating meaning. To broaden the available material qualities, the discussed strategy is developing (and designing with) microstructures to simulate various materials. To enter more functional product domains, or machines, the paper suggests facilitating the integration of mass-produced functional elements (e.g. electronics) into product "shells", realizable with distributed manufacturing. Finally, to compensate for limited distribution and marketing resources, we discuss the strategy of leaving the design project open for user interventions, focusing on the conceptual development of meaningful personalizable design. Regarding this latter, the paper also describes a design method and canvas tool, while the suggestions on materials/machines raise awareness around issues and upcoming solutions, contributing to some parts of the canvas.

Abstract: A new process and technology of rapid prototyping for a μ-micro motor is presented as a nontraditional machining and an advanced manufacturing technology (AMT) to be realized by using masks, including the operation principle of the motor, structure design, technique, driven circuit, and quality examination with Raman spectrum. The μ-micro motor is fabricated by the micro electro-mechanical systems (MEMS) process, the structure design must be considered to fabricate or assembly the parts during machining the motor in the meantime. The research proved that integration of IC (integrated circuit) process and MEMS using masks is effective in obtaining the rapid prototyping manufacturing of the μ-micro motor. With the mature technique to fabricate the motor, there are advantages to produce the motor in short time and with lower cost than before. The motor is a common power source of micro machines in military and civilian applications, for example, applied to micro robot, micro bio medicine, and micro machine. The size of the motor is 190 μm in maximum diameter by 125 μm in height that is bulk machined in array with the number of hundreds of micro motors on a substrate. [Copyright &y& Elsevier]
THREE-dimensional printing, RAPID prototyping, and MACHINING
The article reports on the ability of machining manufacturer Ultra Tech Machinery and technology manufacturer Fabrisonic to combine additive manufacturing and traditional computer numerical control machining into an equipment. Topics mentioned include the chief competitive advantages of 3D printing, the decision of Fabrisonic not to seek alliances with big machine tool companies, and a report from several groups in July 2016 about the potential for 3D manufacturing.

ENGINEERING education, PROGRAMMING languages, MACHINING, CAD/CAM systems, and PILOT projects
There is a growing interest in educating advanced manufacturing to a larger population, especially graduates of STEM fields, without a need for an advanced engineering background. Application of CAD/CAM software in teaching design and manufacturing skills is common, though it often relies on users' knowledge of machine language, e.g., knowing how to write G-code to work with CNC machines, in addition to fundamentals of process planning. A CAM software called SculptPrint was used to familiarize three high-school level students without any background in manufacturing with CNC machines. With simulations of automatically generated machining paths, the students were taught basic manufacturing concepts in process planning and fixturing in a semester-long timeframe. The students fabricated three axisymmetric parts when the software-generated G-code was exported to a CNC lathe. The participants created a set of tutorials and surveys that would be used to teach sophomores in mechanical engineering at Georgia Tech concepts of CNC machining and process planning and evaluate their understanding of choosing manufacturing processes, and process planning in machining specifically. Examples of questions are provided to demonstrate the pertinent machining concepts that the participants learned. The ultimate goal of this research is to help target learners to have a better understanding of choosing between additive and subtractive manufacturing for parts with specific geometries in addition to other prototyping constraints such as cost and time.
