Laser System for Rapid Prototyping
The RapidX250 laser micromachining system can be used in rapid prototyping applications to fabricate microfluidic devices, microelectromechanical systems (MEMS), and medical devices with tolerances approaching 1 µm. Offered by Resonetics LLC, the system employs a multiwavelength 193/248-nm excimer laser to fabricate MEMs directly in a single step. As a result, MEMS fabrication can be accomplished in much less time than it would take to prototype such devices via traditional multistep semiconductor lithography processes, according to the company. The flexible system is able to microfabricate both 2-D sheets and tubes and 3-D parts, including in x-y-z, theta, and goniometer motion coordinate systems. At 193-nm, the laser can cleanly ablate fluoropolymers, bioabsorbable polymers, and glass. The system's quick-exchange function lets the user easily switch to the 248-nm laser wavelength for machining polymers, ceramics, and metals. The user-friendly micromachining system also has a DXF file-to-CNC converter that facilitates conversion of concepts into prototypes.

Laser Cutting System Accessory
The designers' turnkey digital print-to-laser cutting system from Spartanics enables designers of medical devices, printed packaging and labels, faceplates and nameplates, and other laser-cut digital printing products to direct and control all print and laser-cutting finishing specifications at the earliest design stages. Unlike digital laser-cutting lines that require vector-based files to be input during setup, the print-to-laser cutting system allows product developers to use raster-image-processing software at the prepress level to specify not only print files but also laser-cutting files for finishing the product. It features the built-in capacity to extract the vector data embedded in PDF, ONYX, and other formats. In addition, the system allows the use of bar codes to signal job changeovers. This capability enables continuous production and cost-efficiency even with short-run jobs.

Automatic Tubing Coilers
High-performance tubing coilers in the Automatic Cut & Transfer series from Tulsa Power incorporate a dual-spindle-turret winder designed to wind tubing 0.032 to 0.625 in. in diameter in-line as part of an extrusion process. The fully automatic systems are equipped to coil or spool. They also have a cut-and-transfer feature that, upon receipt of a signal from the total-length counter, quickly cuts, clamps, and transfers products from the full reel to the empty reel without process interruption at speeds to 1000 ft/min. An ultrasonic dancer locates the position of the product without making contact and ensures smooth, tension-controlled winding of even very sensitive products. Allowing one operator to manage several extrusion lines, the coilers can reduce labor requirements. Their controls allow for reliable switchovers at high speeds.
