This article presents the design, construction, and test results of a linear ion trap, fabricated using digital light processing (DLP), which is a low-cost 3D layer-based manufacturing technique. The ion trap was incorporated into a portable mass spectrometer system and experimental mass spectrum was obtained for methamphetamine (m/z 182), cocaine (m/z 304), and rhodamine B (m/z 443), with a ma...

Companies and firms, nowadays, due to mounting competition and product diversity, seek to apply virtual cellular manufacturing systems to reduce production costs and improve quality of the products. In addition, as a result of rapid advancement of technology and the reduction of product life cycle, production systems have turned towards dynamic production environments. Dynamic cellular manufact...

While the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. However, the developments of nanoscale components and guiding methods are continuing with a rapid pace. Since waveguiding is a fundamental iss...

*Work supported by the U.S. Department of Energy under contract No. DE-AC02-98CH10886. [email protected] Abstract High field common coil magnets [1,2] using brittle High Temperature Superconductors (HTS) or Nb3Sn cables provide new challenges with respect to the design and manufacturing of coils. We are developing the scaleable techniques that can be used in the production of common coil or oth...

Porous materials and metamaterials play a key role in sound absorbing insulation solutions acoustics. With the growing interest additive manufacturing techniques, recent work has focused on printing of porous resonant structures for acoustic purposes. Usual metaporous surfaces/interfaces are generally built by periodically inserting elements an existing layer. This complex process can be signif...

Reviewed, accepted September 10, 2008 This paper presents methods for the rapid manufacturing of replacement bone fragments using a Subtractive Rapid Prototyping process called CNC-RP. The geometry of segmental defects in bone, resulting from traumatic injury or cancerous tumor resection, can be reverse-engineered working from medical images (such as CT scans), and then accurate defect fillers ...

SYSTEM CONSIDERATIONS IN MONOZUKURI MANUFACTURING THE modern world faces many very difficult challenges, including global warming, resource and energy depletion, and rapid socioeconomic change. At the same time, while rapid progress is being made on establishing the foundations of a prosperous society, there are also calls from around the world for highly reliable social infrastructure that pro...
