A Prandtl probe is one of the standard instruments used for flow characterization in wind tunnel facilities. The convectional fabrication method of this instrument requires skilled artisanship, precision drilling, lathing and soldering of its several parts. This reflects into high costs of production in turn making wind energy studies expensive. With the adoption of additive manufacturing, the tooling costs, skills required and design to manufacture constraints can be addressed. This research presents a Prandtl probe that was designed using NX™ software, fabricated by desktop stereolithography additive manufacturing platform and validated in a wind tunnel for velocity range of 0 m/s to 51 m/s. This research attested the option of fabricating relatively cheap functional Prandtl probe with desktop stereolithography technology which can be used for accurate determination of flow quality in wind tunnels experiments. This provides various learning and research institution in developing countries that have already invested in additive desktop manufacturing technology certainty and a cheaper option to fabricate wind research instruments for use at their laboratories. Moreover, fabrication and validation of a 5-hole Prandtl probe can also be examined.

Compared to conventional sheet forming operations, incremental sheet forming (ISF) is a flexible forming technique that can achieve higher formability in terms of localized deformation. Due to excellent mechanical properties and X-ray penetration, polyether-ether-ketone (PEEK) is an ideal alternative to titanium alloy and stainless steel in orthopedic applications. In this study, a 3-axis desktop manufacturing system has been fabricated to investigate the temperature-dependent formability of PEEK in terms of manufacturing the cranial plate by using the ISF technique. Meanwhile, the forming force, temperature distribution, geometrical accuracy, and thermal properties were obtained and analyzed. The findings indicate that the ISF technique provides technological and economic advantages in cranial reconstruction by using PEEK.

This paper examines a new paradigm in the world of manufacturing—distributed manufacturing based on desktop manufacturing (DM)2. The evolution of (DM)2 began in the last decade of the 20th century and its technological development is well underway, as is evidenced by a World Technology Evaluation Center study (www.wtec.org). However, as managers begin to assess the competitive advantages of moving to this manufacturing model it will be important to consider the social and environmental implications of this paradigm shift as well as issues related to materials and energy utilization. The factors that now appear to be driving the need for radical departures from the more traditional manufacturing paradigms have been broadly articulated but the longer-term future of this manufacturing model is less clear. Several scenarios are proposed and discussed that suggest how manufacturing will shift to a more distributed model via the concept of desktop manufacturing (DM), which will coexist with the centralized manufacturing model but likely take on a greater and greater share of the total manufacturing market worldwide. Spurred on by the rapid emergence of miniaturization technologies, the development and refinement of these desktop manufacturing scenarios needs to be examined in the context of a number of important socioeconomic, environmental, and materials and energy utilization issues as (DM)2 continues to evolve as a transforming paradigm for the world of manufacturing. Scientific, technical, and economic barriers and challenges are identified and discussed.
